Safety and Conformity

Safety Instructions

• Danger to life due to lethal voltages Lethal voltages are present within the unit and on the power supply lines. Therefore, only authorized electricians may install  and open the unit. Even when the unit is disconnected, high contact voltages may still be present within the unit. Danger of burn injuries due to hot enclosure parts
• During operation, the four sides of the enclosure lid and the heat sink may become hot. Only touch the front enclosure lid during operation.
• Grounding The PV Generator Comply with the local requirements for grounding the PV modules and the PV generator. We recommend connecting the generator frame and other electrically conductive surfaces in a manner which ensures continuous conduction with ground in order to have optimal protection of the system and personnel.
• Capacitive Discharge Currents PV modules with large capacities relative to earth, such as thin-film PV modules with cells on a metallic substrate, may only be used if their coupling capacity does not exceed 470nF. During feed-in operation, a leakage current flows from the cells to earth, the size of which depends on the manner in which the PV modules are installed (e.g. foil on metal roof) and on the weather (rain, snow). This “normal” leakage current may not exceed 30mA due to the fact that the inverter would otherwise automatically disconnect from the electricity grid as a protective measure
• Un authorised engineer opening the unit will void the system

DC and AC Breaker

The system is to be fitted with DC battery isolation and AC isolation.

Grounding The PV Modules
This unit is a transformer-less inverter. It has no galvanic separation. Do not earth the DC circuits of the PV modules to the inverter. Only Earth the mounting frame. If you bond the PV modules to the inverter you will receive an error message “PV ISO Low”.

Product Description

Inverter Line Drawing

Operation of the Unit

Energy produced by the PV system is used to optimize self-consumption. Excess energy is used to charge the batteries, once the batteries are full the surplus is then fed into the public grid When PV energy output is insufficient to support connected loads, the system automatically draws energy from the batteries if battery capacity is sufficient. If the battery capacity is insufficient to meet own consumption requirements, electricity will be drawn from the public grid.

Storage of Inverter

Choose an appropriate location.

• The unit must be stored in original packaging.
• The storage temperature should be always between -25°C and +60°C.
• The storage relative humidity should be always between O and 95%.
• Do not stack no more than 4 high.

Selecting the Installation Location

This is guidance for the installer to choose a suitable installation location.

• The inverter shall not be installed where in direct contact with water or in direct sunlight.
• The unit shall be mounted at least 914 mm (3 feet) above the ground.
•  The installation location must be suitable for the inverter’s weight and dimensions for a long period of time.
• Select the installation location so that the status display can be easily viewed
• Do not install the inverter on structures constructed of flammable materials.
•  The humidity of the installation location should be O – 95%, without condensation.
• The installation location must be safely accessible to get to at all times.
• Vertical installation or tilted backwards by max. 15° and make sure the connections of inverter are at the bottom. Never install horizontally and avoid forward and sideways tilt.
• Be sure that the inverter is out of the children’s reach.
• Do not put anything on the inverter. Do not cover the inverter.
• Do not install the inverter near television antennas.
• The Inverter requires adequate cooling space. Provide the best ventilation for the Inverter to ensure the heat escapes adequately. The ambient temperature should be below 40° C to ensure optimum operation.
• The inverter should not be installed in direct sunlight, direct heavy water sources or unstable locations. We recommend that the inverters be installed at a location with some cover or protection.
• Observe the minimum clearances to walls, other inverters or objects as shown in the diagram below in order to guarantee sufficient heat dissipation.

Clearance using Inverters In Series

• There must be sufficient clearance between the individual inverters to ensure that the ambient air from the adjacent inverter is not taken in.
• If necessary, increase the clearance spaces and make sure there is enough fresh air supply to ensure sufficient cooling of the inverters, and heat dissipation

Mounting the Inverter Bracket

WARNING
In order to avoid electrical shock or other injury, inspect existing electrical wiring systems or plumbing installations before drilling holes for bracket fixings

• The dimension of bracket as in [Figure 8]:
• Using the mounting frame as a template, drill holes as illustrated in the i mage below.
• PLEASE NOTE: If damage arises to the inverter as a result of insufficient fixings so as to withstand the load of the inverter, or the installation is not carried out in accordance with the manufacturer”s requirements, the warranty may be voided.

Mounting the Inverter on the Wall

Falling equipment can cause serious or even fatal injury. Never mount the inverter on the bracket unless you are sure that the mounting frame is securely mounted on the wall.

• Raise the inverter a little higher than the bracket. Consider the weight during the process to maintain the balance of the inverter. Hang the inverter on the bracket through the hooks on bracket.
• After confirming the inverter is fixed securely, insert the Two safety locking pins on the left and right side to prevent the inverter from being lifted off the bracket.

Check Inverter Installation Status

• Check the mounting of the inverter by trying to raise it from the bracket. The inverter should remain firmly attached.
• Please ensure that the correct mounting surface is selected to allow for vibration of the inverter during normal operation.

Electrical Connection Safety

• Danger: To Life Due To Lethal Voltages! High voltages which may cause electric shocks are present in the conductive parts of the inverter. Prior to performing any work on the inverter, disconnect the inverter on the AC side, PV side and battery side. Do not reverse the polarity of the battery! It will damage the inverter and void any warranty.
• Danger: of damage to electronic components due to electrostatic discharge. Take appropriate ESD precautions when replacing and installing the inverter.
• EARTHING: Before connecting the DC power cables, the AC supply must be earthed.

Installation Diagram

NOTE: Ensure all wiring is correctly selected and connected in accordance with BS7671 :2018, IET wiring regulations.

Connect To The Grid (AC Utility)

• A Conductor Cross-section: See the conductor cross section in the flow chart
• B Bare Length: 8mm around

Suggestions for the PV modules of the connected strings:

• Same type of modules
• Same quantity of PV modules connected in series

Under all conditions! Make sure the maximum open circuit voltage (Voe) of each PV st ring is less than 600Vdc.

• Do not connect strings with an open circuit voltage greater than the maximum input voltage of the inverter. If the string voltage exceeds the maximum input voltage of the inverter, the inverter can be damaged due to overvoltage. All warranty claims become void.
• Check the design of the PV installation. The max. open circuit voltage, which can occur at solar panels ambient temperature of -10°C, must not exceed the max. input voltage of the inverter.
  • Before connecting PV panels to the DC terminals, please make sure the polarity is correct. Incorrect polarity connection could damage the inverter.
  •  Check short-circuit current of the PV string. The total short-circuit current of the PV string should be less than the inverter’s maximum DC current.
  • Connect the positive and negative terminals from the PV panel to positive{+) terminals and negative{-) terminals on the PV-Inverter. Each DC terminal on Inverter can withstand 11 A.
• For instance, if the positive pole of a string is connected at MPP tracker A and the string’s negative pole at MPP tracker B, this is called a mixed connection, the inverter no longer fulfils the requirements of the EMC Directive.
• Only connect strings at one input zone and never mix the input zones A and B.
• High voltages exist when the PV panel is exposed to the sun. To reduce risk of electric shock, avoid touching live components and treat connection terminals carefully.

Connect To The Battery

Before connecting to the battery, you must install a separate DC breaker {not less than 63A) between the inverter and battery. That will ensure the inverter can be securely disconnected during maintenance.

danger: Reversed Polairty will damage the inverter.

• It is very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of injury, you much use the proper recommended cable size, refer to the following
•  The battery must be installed in accordance with the manufacturer’s instructions.
• The MAX charge/ discharge current of the inverter is S0A.
• The inverter’s battery rated voltage is 51.2V nomimal. The battery series connection voltage must not exceed 51.2V nominalor it will damage the inverter and void any warranty.

Follow the below steps to implement the battery connection:

1. Check the battery nominal voltage meets the inverter spec.
2. Disconnect the breaker between inverter and battery.
3. Check out the polarity of the battery and the inverter.
4. Terminate battery DC cables by means of the lugs provided.
5. Screw the DC cable to the inverter’s battery input terminal.
6. The correct battery technology must be selected upon commission, so that it can be controlled via the BMS Figure 19

we recommend using the GivEnergy appointed lithium battery, because the battery BMS communication has been designed to be compatible with the GivEnergy Hybrid Inverter.

Danger to life due to voltages
Before you install the BAT.NTC, you must turn off the inverter, check all the separate breakers are off, and the inverter’s LED is off. Then you can safely install the BAT.NTC terminal to the inverter.

Connecting Monitoring Point

In the system, a CT or mid approved meter must be installed to monitor the power of the house to decide the inverter status: charge or discharge. CT or meter must be installed at the origin of supply. In this case, the inverter can monitor all household consumption of power. According to the sensor, the inverter will control the PV power feeding to the grid to balance the level of household power use.

Place the CT reader in-between the meter and the inverter. This must be positioned in front of local load and around the LIVE wire only with the arrow pointing TOWARDS the inverter.

The Inverter Parameter Setting

Connect to the inverter via the Engineers software or portal to set the battery parameter, grid charge time, inverter discharge time and various other functions.

Without setting the parameters, the inverter will not be commissioned.

WARNING: Check that all the wire s are securely connected before the battery breaker and the AC isolator is switched on. The PV should be switched on first to start the inverter, and you MUST set the parameter of battery according to your battery system.

Communication

Wi-Fi/GPRS
Hybrid inverter uses Wi-Fi/GPRS as standard wireless communication.

DRM
The DRM connection CN8 in the front plate, as the picture:

When it receives the order from DRM0 connection, the inverter will act responding to the order, the output power should be reduced to 0 (Short connection between Rj45 No.5 and No.6).

Start-Up And Shut Down of the Inverter

Start-Up and shut porcedure

1. Connect the AC circuit breaker, ensure system is reading import
2. Turn on the PV isolator;
3. Turn on the battery breaker, then turn on the battery;
4. The inverter will start automatically when the PV voltage is higher than 1 S0V and the battery voltage is higher than 46.4V;

Shutting down the Inverter

1. Turn off the AC circuit breaker to prevent it from being reactivated;
2. Disconnect the Battery breaker to prevent it from being reactivated;
3. Turn off the PV isolator;
4.  Check the inverter operating status;
5. Wait until LED display has gone out, the inverter is shut down.

Maintenance and Cleaning

Checking Heat Dissipation

If the inverter regularly reduces its output power due to high temperatures, please improve the heat dissipation conditions. You need to clean the heat sink, or look for other obstructions.

Cleaning the Inverter
If the inverter is dirty, please shut down the inverter and clean the enclosure lid.

Checking the DC Switch
Check for externally visible damage and discoloration of the breaker, and the cables at regular intervals. If there are any signs of visible damage to the breaker, or visible discoloration or damage to the cables, contact the installer.

A Once a year, turn the rotary switch of the DC switch from the On position to the Off position 5 times in succession. This cleans the contacts of the rotary switch and prolongs the electrical endurance of the DC Disconnect.

Decommissioning

Uninstalling the Inverter

1. Disconnect the inverter as described;
2. Remove all connection cables from the inverter;
3. Remove locking pins;
4. Lift the inverter off the bracket and unscrew the bracket screws;

Danger of burn injuries due to hot enclosure parts! Wait 20 minutes before disassembling until the housing has cooled down.

Boxing the Inverter

If possible, always pack the inverter in its original packaging and secure it with tension belts. If this is no longer available, you may also use an equivalent sized carton. The box must be capable of being closed completely and made to support both the weight and the size of the inverter.

Storing The Inverter
Store the inverter in a dry place where ambient temperatures are always between -25°C and +60°C.

Work Modes

The GivEnergy Series Hybrid Inverter has the following main work modes:

DAYTIME MODE
The system optimizes the delivery of generated PV power, prioritizing LOCAL loads then BATTERY if necessary and finally ending excess generated power to the GRID.

NIGHT TIME MODE / ON PEAK EVENING
This is prioritized to discharge the battery ready for the OFF PEAK time to refill if necessary at the cheapest rate. When the battery is depleted automatic switching will occur and GRID power will be used.

EMERGENCY BACK UP AND ISLAND MODE
The system has the ability to be a stand alone system in ISLAND MODE. There is also an essential backup power system available for use when there is a power cut.

DEMAND SIDE RESPONSE
There is an option in our software to allow remote data collection/analytics. This gives vital information to utility providers and can allow a high level of indication to when demand will occur.

Manufacturer Warranty

This inverter is covered by a 5 year warranty. Completion of the commissioning process registration validates a standard factory warranty of 5 years from the date of commission
