Welcome

Hi, nice to meet you! Ready to get ECTIVE?

Thank you for choosing an ECTIVE CSI PRO inverter! Devices in the CSI PRO series are among the most advanced inverters from ECTIVE. They provide highquality alternating current with a pure sine wave, which can also be used to operate sophisticated and complex electronic loads: Power just like from a 230 V earthed socket at home – anytime and anywhere.
Thanks to special additional features such as a quiet fan, an integrated residual current circuit breaker with overcurrent protection and a particularly powerful charger, these inverters really deserve the product name ‘PRO’.

In order to supply even the most demanding electronic loads with clean power, the inverter converts direct voltage, such as that provided by a utility battery, into alternating voltage. Thanks to numerous protection mechanisms, durable power electronics and intelligent microprocessor control, CSI PRO inverters guarantee a high overload capacity and can therefore also supply loads with high starting currents or short-term high peak consumption without restrictions. This means that nothing stands in the way of a self-sufficient power supply for the most diverse and demanding devices.

To maximise flexibility, inverters from the CSI PRO series offer the option of using different power sources. If a shore power connection is available, this can not only supply consumers with energy via the inverter, but can also charge the connected supply battery thanks to the IUoU charger built into the CSI PRO. CSI PRO inverters are of course compatible with all ECTIVE batteries and, in addition to conventional wet batteries, also support advanced batteries with AGM, gel or lithium batteries. With practical functions such as mains or battery priority switching, operation can be customised to individual requirements at any time.

Safety Instructions

Read the operating instructions carefully before installing and using your ECTIVE PRO inverter.
Only use the device in accordance with the intended use described therein and observe the following safety instructions:

• Keep the inverter away from naked flames, sparks and heat sources as well as dust and moisture.
  Protect the device from impact and damage. Switch off the inverter for cleaning and only use dry cloths.

• Keep children away from the inverter.

• Avoid short circuits and polarity reversals at all costs.

• Do not open the housing of the inverter under any circumstances. Maintenance and repairs may only be carried out by a specialist who is familiar with all current guidelines (e.g. VDE guidelines). Ensure adequate ventilation in accordance with the instructions in the ‘Installation’ section.

• he inverter may only be connected to a power grid via the DC input, whereby the input voltage of 12 V must not be exceeded. Connecting to higher voltages will cause the fuse to blow immediately and can lead to irreparable damage to the inverter.

• Never connect an AC voltage source to the 230 V output of the inverter (earthed socket)! Such a connection poses a risk to life as well as immediate and irreparable damage to the inverter.

• Use cable sets with the correct cross-section. Observe the instructions in the ‘Connections and commissioning’ section. The 230 V output cable and DC supply cables must never be laid together in the same cable duct.

• Observe the maximum total output of the connected loads. Some loads require a short-term starting current at start-up, which can be significantly higher than the regular operating current. For this purpose, ECTIVE CSI PRO inverters can supply 150 % power for 10 seconds or 200 % power for 2 seconds.

• If the recommended total capacity (or the recommended continuous discharge current in the case of lithium batteries) is not reached, voltage dips may result in a loss of performance or severe restrictions on use.

• The device is equipped with safety mechanisms to prevent dangerous electric shocks. To ensure the highest possible level of protection during operation, the inverter‘s earth connection must be connected to a protective earth. The inverter must not be used in vehicles in which the positive pole is connected to the vehicle body.

• When not in use, switch off the inverter at the main switch after disconnecting it from the shore power. Current is also drawn when the inverter is idle, which may result in deep discharge of the connected battery. Observe the notes in the section ‘Notes on operation’.

• The inverter has various safety functions that automatically switch off the AC output in the event of faults. These include overheating, overpower and input voltage that is too high or too low. Observe the instructions and fault diagnosis in the ‘Troubleshooting’ section. Eliminate sources of faults immediately, as repeated switching on in the event of a fault can lead to damage to the device.

• Failure to comply with these safety instructions and the operation described in the manual will invalidate the warranty provided by the manufacturer. The manufacturer accepts no liability for damage caused by improper use.

Installation

Please observe the following installation instructions when installing your ECTIVE CSI PRO inverter:

• Disconnect the inverter from the power supply before installing or working on the device.
• Never open the housing of the inverter.
• Only mount or screw the inverter to solid mounting surfaces.
• Install the inverter in a location where it is protected from direct sunlight, heat sources, dust and moisture.
• The inverter can be installed both horizontally and vertically.
• Lay the cables so that they are not under tension or pull on the connections.
• When used on boats, inadequate sealing can cause corrosion damage. The installation should therefore be carried out by appropriately trained personnel.
• Use empty conduits or cable ducts to protect the cables.
• Never lay the 230 V output cable and DC supply cables together in the same cable duct.
• To ensure the highest possible level of protection, the inverter‘s earth connection must be connected to a protective earth. The inverter must not be used in vehicles in which the positive pole is connected to the vehicle body.
• As the inverter radiates heat during operation, it should be installed away from objects that are sensitive to high temperatures.
• Never cover the ventilation slots or the fan. To ensure good ventilation, the distance between the ventilation elements and the nearest surface must be at least 10 cm. If overheating occurs due to insufficient ventilation, the inverter switches off automatically.

Orientation of the inverter

The inverter can be mounted both horizontally and vertically.

Minimum distance for sufficient ventilation

The distance between ventilation elements and the nearest surface must be at least 10 cm. Ventilation slots and fans must not be covered.

Dimensions of the inverter

When installing in confined spaces, observe the minimum distance of 10 cm in front of the ventilation elements!

Connections and Commissioning

• Observe the following instructions when connecting and commissioning your ECTIVE CSI PRO inverter. In addition, all instructions in the ‘Safety instructions’ section must be followed to ensure safe operation.
• Inverters of the ECTIVE CSI PRO series are intended exclusively for use in stand-alone, so-called ‘off-grid’ areas. Never connect an AC voltage source to the 230 V output of the inverter (earthed socket)! Such a connection poses a risk to life as well as immediate and irreparable damage to the inverter.
• The inverter may only be connected to a power grid via the DC input, whereby the nominal input voltage of 12 V must not be exceeded. Connecting to higher voltages will cause the fuse to blow immediately and can lead to irreparable damage to the inverter.
• Ensure a suitable battery capacity or, in the case of lithium batteries, a suitable continuous discharge current. Follow the instructions on the following page.

Connect and commission the inverter

• First make sure that the inverter is disconnected from the shore power and switched off at the main switch (no LEDs light up). If the input voltage is a supply device such as a generator, switch this off as well.

• Use the DIP switches on the inverter to set the correct battery technology. Observe the following diagram:
  

• Connect the inverter to the battery, paying close attention to the polarity. During this step, sparks may occur due to the charging of the internal capacitors. Be sure to use cables with the appropriate cable cross-sections specified on the next page, as well as an appropriate fuse.

• If necessary, connect the inverter to the shore power or a generator.

• Switch on the inverter at the main switch and wait approx. 12 seconds for the inverter to start up. If shore power is available, the device switches on automatically.

Required battery capacities, cable cross-sections and fuses

When planning and installing your power supply, observe the specifications applicable to your inverter model. If the total capacity of the batteries falls below the recommended level, this may result in a loss of performance or severe restrictions on utilisation due to voltage dips.

Possible use of shore power
Two systems can be designed for the use of shore power, e.g. the power supply for a caravan on a campsite: If the entire power supply runs via the ECTIVE PRO inverter, no additional fuse is required as the inverter has an integrated residual current circuit breaker with overcurrent protection switch.
However, if the system includes a branch upstream of the inverter to which other sockets are connected, this part of the grid must be protected separately by an RCD. In any case, the connections to the supply batteries must be fitted with suitable fuses.

Full protection via the inverter.

Additional RCD protection necessary
Parallel connection of batteries

In order to provide the inverter with a higher total capacity, several identical batteries can be connected in parallel to form a battery bank. The voltage does not change when connected in parallel, so make sure you only use 12 V batteries!
In the following example, three ECTIVE LC 100 LiFePO4 batteries with a capacity of 100 Ah each were connected in parallel. The total capacity is 300 Ah and is therefore sufficient to operate a CSI 30 PRO as intended. A suitable fuse (see table on page 13) must be used when connecting the positive terminals.

Personal protection in the TN network
Inverters from the ECTIVE PRO series provide a so-called TN grid. This is an ‘earthed system’ – the neutral point of the system is directly earthed via the operating earth electrode and all bodies of the individual loads are connected to the operating earth electrode (PE).

Electrical installations must fulfil the requirements of personal protection in two ways:

Basic protection:
Protection of the person by preventing direct contact with the live parts of the equipment. This includes, for example, complete insulation of cables and covering them with an enclosure.

Fault protection:
Protection of the person against electric shock in the event of indirect contact, e.g. touching a live enclosure. This can be the case if, for example, a defective cable comes into contact with the conductive, earthed enclosure. In this situation, the basic protection has failed and the safety of the person must be guaranteed by the fault protection.

In TN systems, overcurrent protection devices and residual current devices in particular must be provided to protect against disconnection or fault signalling.

If a person touches a conductive enclosure that is energised due to a short circuit in a correctly planned and designed TN system, a high residual current immediately flows via the person to the power source. The system must therefore have suitable protective mechanisms such as fuses and RCDs that disconnect the circuit before people can be harmed. In an earthed system, a single fault will result in the entire system being switched off.

You can find more information on personal protection in different types of network here:
ective.de/mediafiles/Datenblatt/ective/Inverter-2024/ECTIVE-Personenschutz- im-IT-und-TN- Netz.pdf

Operation

To ensure safe and proper operation, please observe the following instructions and technical conditions.

Operating Conditions

• Operating temperature: -15°C to 40°C
• Storage temperature: -40°C to 85°C
• Relative humidity: 20% to 90%

Please note that performance may be reduced at ambient temperatures above 40 °C. In addition, the inverter has built-in overheating protection, which automatically switches off the device if the internal temperature exceeds 75 °C.

Maximum Total Output
Ensure that the total output of all connected loads does not exceed the maximum output of your inverter model. This also applies if the loads are supplied exclusively with shore power (bypass function in UPS mode).

CSI 25 PRO and CSI 30 PRO: Consumers with continuous currents over 10 A must not be connected to the earthed socket. Instead, use the direct connection on the AC terminal (‘AC output’).

Starting Currents – Power When it Counts
Some loads require a short-term starting current at start-up, which can be significantly higher than the regular operating current. Integrated protective circuits, durable power electronics and intelligent microprocessor control of the ECTIVE CSI PRO inverters guarantee a high overload capacity. This means you can also use loads with high starting currents or short-term high peak consumption safely and without restrictions:

• 150 % power for 10 seconds
• 200 % power for 2 seconds

Errors and Troubleshooting
Thanks to numerous built-in protection mechanisms, the ECTIVE CSI PRO inverter switches off automatically in the event of various faults. Status LEDs and any acoustic signals indicate the problem and allow the fault to be rectified. In such cases, follow the instructions in the ‘Troubleshooting’ section.

ECO Mode (Battery Priority) and UPS Mode (Mains Priority)
Inverters in the ECTIVE CSI PRO series can be operated in ECO mode or in UPS mode.

In ECO mode (battery priority circuit), the inverter supplies the loads with power from the connected battery, even if the system is connected to shore power. If the battery voltage falls below 11 V, the inverter automatically switches to UPS mode. If the battery is then charged so that the battery voltage returns to 14.2 V, the system switches back to ECO mode.

The UPS mode (mains priority circuit) provides an uninterruptible power supply: Connected 230 V consumers are supplied with shore power as a priority, while available shore power is used to charge the connected batteries. If the connection to the shore power is disconnected, the inverter switches to battery operation within 16 ms.

The green ‘ECO’ and ‘UPS’ LEDs on the inverter control panel make it easy to recognise which mode the device is currently operating in. In addition, the ‘Inverter’ and ‘By-Pass’ LEDs indicate whether the inverter is currently converting direct current from the battery into alternating current to operate loads (‘Inverter’) or whether shore power is being fed through directly to the loads (‘By-Pass’).

To switch between the modes , press and hold the main switch for a few seconds until the LED for the desired mode lights up and the other LED goes out. Press and hold the button for a further two seconds and then release it. For technical reasons, the other LED may shimmer slightly green depending on the lighting conditions.
In any case, the brightly lit LED indicates which mode the inverter is in.

For more detailed information on the behaviour of the inverter in the respective modes, please read the section ‘Battery Charger’

Idle Current
The inverter also draws current when idling. This can lead to a deep discharge of the connected battery, which can cause permanent damage to the battery. Therefore, switch off the inverter when not in use: First disconnect it from the shore power and then switch off the device at the main switch. To do this, press and hold the button for several seconds until the status LED changes from ‘ECO’ to ‘UPS’ or vice versa. Then release the button. It is not possible to switch off the inverter as long as shore power is present. In this case, the inverter switches back and forth between ECO and UPS mode when the main switch is pressed.

Press and hold the main switch for several seconds until the LEDs change. Then release the button to switch off the inverter.

Only possible if there is no shore power.

Overwintering & Prolonged Non-Use
If the inverter will not be used for an extended period of time, please observe the following instructions to protect your battery from discharging:

• Disconnect the inverter from all connected power sources.
• Disconnect all loads from the inverter.
• Switch off the inverter.
• Disconnect the battery from the inverter by disconnecting the connecting cables or using a circuit breaker to prevent deep discharge of the battery.
• Store the inverter out of the reach of children in a dry place, protected from direct sunlight.

Battery Charger

Inverters in the ECTIVE CSI PRO series have an advanced integrated battery charger with IUoU charging characteristic, which can be used to charge connected batteries directly with shore power.

Integrated Battery Charger
The right charging process for all battery technologies: In addition to standard wet batteries, the integrated multi-stage charger is also suitable for AGM, gel and LiFePo4 batteries (with BMS). An optimum charging characteristic can be selected for each battery technology. To do this, set the DIP switches on the inverter according to the overview on p. . 22.

Technical Properties

Efficiency (Charger): up to92 %

The function of the charger and the individual charging phases are explained in detail on the following pages.

The Three Charging Phases
Both the integrated charger and the MPPT solar charge controller charge connected batteries with a fully automatic 3-stage IUoU charging characteristic that is optimised for each battery technology. The system runs through the following three phases over the course of charging:

Main Charge („Bulk“): The battery is charged at a constant current and carefully increasing voltage up to a predefined maximum voltage value until 80% of the total charge has been reached.

Residual Charge („Absorption“): The battery is fully charged from 80 % to 100 % capacity using a constant voltage and gradually decreasing currents. The gradually decreasing current ensures that the terminal voltage does not become too high during full charging. The charging voltage depends on the battery technology, which can be selected using the DIP switches on the device.

Float Charge („Float“): The battery is kept evenly at ‘float’ voltage without overcharging or damaging it. The battery voltage is constantly monitored during this charging phase. If it falls to a predefined level, the battery is recharged to 100 % by pulse charging. In this way, it is constantly kept between 95 % and 100 % state of charge.

The current charging phase of the system can be easily recognised by the corresponding status LEDs:

Power: The charger is working.
Float: Trickle charge.
ABS: Residual charge.
Bulk: Main charge.
Wake up: A connected LiFePO4 battery is reactivated after it has been switched off by its internal BMS.

Note that the charging and discharging of the batteries depends on whether the inverter is operating in ECO mode or UPS mode.

In ECO mode, no shore power is used to operate utilities or charge batteries, even if the inverter is connected to shore power. The consumers are supplied with power from the batteries and these are only recharged with solar power – if available.

In UPS mode, the batteries are charged with both solar and shore power.
Follow the instructions in the section ‘ECO and UPS Modes’.

Useful accessories

not included in scope of delivery.

Please note: The conventional ECTIVE RC1, RC2, RC3 and RC4 models are not compatible with PRO series inverters.

Setting the battery technology using DIP switches
Before connecting a battery to the inverter, set the DIP switches to the battery technology used according to the diagram below. The inverter uses a specially adapted charging characteristic for each battery technology to ensure efficient and gentle charging.

DIP switch| Battery Technology| Voltage (Main and Residual Charge)| Voltage (Float Charge)
---|---|---|---
| LiFePO4| 14,6 V|
| Wet| 14,8 V| 13,8 V
| Calcium| 15,0 V| 13,8 V
| AGM| 14,6 V| 13,4 V
| SLA| 14,4 V| 13,4 V
| Gel| 14,2 V| 13,2 V
Constant Voltage
| 3,8 V| |
| 12,0 V| |

ECO and UPS Modes

The following overview describes the behaviour of the inverter in ECO or UPS mode under various conditions. The different scenarios are shown graphically in the diagram on the next page. A general explanation of the two modes and how to switch between ECO and UPS mode can be found on page 17.

ECO and UPS Modes

ECO Mode
In ECO mode, connected consumers are supplied with power from the battery. Even if shore power is available, it is not used to charge the batteries. If the battery voltage falls below 11 V, the inverter automatically switches to UPS mode. Once the batteries have been charged to such an extent that the battery voltage is back to 14.2 V, the device switches back to ECO mode.

UPS Mode
Szenario 1: Shore power is available
T0 – T5: (bypass current)
The inverter feeds shore power through to supply connected loads, the ‘Bypass’ LED lights up. Batteries are charged with shore power.

Szenario 2: Shore power fails
T5 – T6: (UPS function/inverter function)
If the shore power supply fails, the system automatically switches from the bypass function to the inverter function. The connected batteries are used to power the consumers and are loaded up to a battery voltage of 11 V.

Szenario 3: Shore power becomes available again after failure
T6 – T9: (Charging with charger)
As soon as shore power is available again, the system immediately switches to bypass mode and the batteries are immediately charged by the integrated charger.

Szenario 4: Shore power fails a second time
T9 – T10: (deep discharge of batteries, e.g. in an emergency situation)
If the shore power connection is disconnected a second time, the inverter switches back to inverter mode. The batteries are emergency discharged to a battery voltage of 10.2 V. If the battery voltage falls below this threshold value, the consumers are no longer supplied with power.

Szenario 5: Charging according to scenario 4
T10 – T11: (Charging after emergency situation)
If shore power becomes available again after scenario 4 (emergency discharge down to 10.2 V), the batteries are charged immediately to prevent damage to the batteries as quickly as possible. Charging takes place until a battery voltage of 14.2 V is reached.

Safety Features

The following safety functions of the ECTIVE TSI PRO inverters protect the user, devices and battery during operation.

• Overvoltage and Undervoltage Protection
  Switches the inverter off automatically if the set values are exceeded or undercut, prevents damage to the inverter and deep discharge of the supply batteries.

• Reverse Polarity Protection
  Immediately triggers the inverter fuse if the battery cables are reversed.

• Soft Start
  Limits the power required when switching on the inverter, thus reducing the load on the batteries and preventing fuse failures.

• Overload Protection
  Automatically switches off the inverter if the loads place too high a power demand on it.
  Overheating Protection
  Switches the inverter off immediately at internal temperatures above 75 °C.

• Short-Circuit Protection
  Switches the inverter off immediately in the event of a short circuit at a load.

• Residual Current Circuit Breaker With Overcurrent Protection
  Switches the circuit off automatically in the event of residual currents.

• Warning Signals
  In the event of a fault, acoustic signals and status LEDs draw attention to the underlying problem. Follow the instructions in the ‘Troubleshooting’ section.

Under certain circumstances, the device may remain switched on even after the AC output has been disconnected. In this standby mode, no-load current continues to be drawn and there is a risk of deep discharge of the connected battery. The AC output of the inverter is automatically switched off in the following fault cases:

• The internal temperature of the inverter exceeds 75 °C.
• The required power is above the continuous power of the inverter or above the short-term maximum power for starting currents.
• The input voltage is either too high or too low.

Please note that damage caused by reverse polarity and short circuits is excluded from liability.

In the event of an error, observe the ‘Fault’ LED and the acoustic signal to identify the problem. Rectify the fault as quickly as possible by following the instructions in the ‘Troubleshooting’ section.

Troubleshooting

The following overview contains solutions on how you can easily and safely rectify typical faults on the inverter yourself.

• Always follow the instructions in the ‘Safety instructions’ section when working on the inverter and the system connected to it.

• After rectifying a problem, make sure that the source of the fault has actually been eliminated.
  Repeated switching on while problems still exist can lead to irreparable damage to the device.

• Avoid short-circuits and polarity reversals at all costs, as these can cause damage to the appliance despite fusing and protective mechanisms.

The CSI PRO in the ECTIVE Eco System

The inverters in the ECTIVE CSI PRO series fit perfectly into the ECTIVE ecosystem, as they are compatible with batteries of all technologies. As a powerful charge controller is installed directly, no external battery charger is required to charge supply batteries with shore power. With an additional MPPT solar charge controller from ECTIVE, you can also use solar power to charge the batteries. This means that nothing stands in the way of an absolutely self-sufficient and mobile power supply, which only includes high- quality and perfectly harmonised ECTIVE products. By the way: the modern ECTIVE RC PRO remote control can be used for convenient operation and monitoring of the relevant values.
Would you like to add the right ECTIVE components to your system? We have put together a few suggestions here! Find out more at ective.de!

ECTIVE RC PRO

The ECTIVE RC PRO remote control is simply connected to the ECTIVE PRO inverter via an RJ12 cable and shows many relevant system values on a clear display:

• Current mode (ECO or UPS)
• Battery charge level
• Input and output voltage
• Power output
• Temperature
• Solar and shore power

You can easily switch between ECO and UPS mode at any time at the touch of a button, even if the inverter is not directly accessible.

Please note: The conventional ECTIVE RC1, RC2, RC3 and RC4 models are not compatible with PRO series inverters.

ECTIVE MPPT Solar Charge Controllers
Solar charge controllers are the link between the solar module and the battery, enabling a self-sufficient power supply in which the batteries are charged with solar power. The technically advanced MPPT charge controllers from ECTIVE adjust their input voltage so that the solar system always delivers maximum power.
Supplement your mobile power supply with a charge controller from the ECTIVE SC, ECTIVE DSC or ECTIVE SC PRO series to utilise solar power and be truly independent:

• ECTIVE SC Silent

• ECTIVE DSC

• ECTIVE SC PRO

ECTIVE Batteries
In combination with ECTIVE PRO inverters, modern ECTIVE LiFePO4 batteries are ideal for a reliable and efficient stand-alone power supply. The LC Slim BT, LC Under Seat BT and LC BT+LT series impress with their high maximum capacities, continuous discharge currents, practical Bluetooth function and numerous other features. Of course, you can also use batteries with other technologies (e.g. AGM or gel). Please note the capacity recommendations on p. 13.

ECTIVE Solar Panels
In combination with an external MPPT solar charge controller, you can utilise the entire ECTIVE solar panel range to make your power supply even more independent. Whether lightweight, flexible or portable for absolute independence: ECTIVE has the right solar panel series for every application.
