Product Usage Instructions

Installation of WI800-12 and WI800-24

Battery Cables: Connect the WI800-12 and WI800-24 inverters to the battery using appropriate cables. Use the following table to determine the cable section based on the distance between the inverter and the battery

1. AC Connection: Connect the AC load to the 230Vac output using the standard SCHUKO connection. Do not connect the inverter output to another AC source, such as the grid or a generator.
2. Inverter Power Saving Mode: Set the power switch I-0-II to position II [ECO] to activate the energy-saving function. This function reduces standby power consumption by 70% by activating the inverter for a short period every 2.5 seconds. The inverter switches to always ON mode for loads above 30W and returns to power saving mode for loads below 20W.
3. Renewable System: If you have a renewable energy system, connect it to the battery terminals using a dedicated charge controller. Always connect the WI800 inverter battery cables directly to the battery terminals.
4. Remote On/Off: Connect a remote power switch to the dedicated 2-pole connector by removing the default jumper. Make sure the power switch is set to ON or Power Saving mode.

LED Indication Definitions
Please refer to the following table for the LED status and error indications

overload
Green ON, Red DOUBLE FLASHING| Green OFF, Red ON| Imminent shutdown due to low battery
Green ON, Red FAST FLASHING| Green OFF, Red ON| Imminent shutdown due to high temperature
N/A| Green OFF, Red ON| Shutdown due to overload
N/A| Green OFF, Red SLOW FLASHING| Shutdown due to low battery
N/A| Green OFF, Red DOUBLE FLASHING| Shutdown due to high temperature
N/A| Green OFF, Red FAST FLASHING| Shutdown due to overvoltage

FAQ

• Q: Can I connect the inverter output to another AC source?
  A: No, you should never connect the inverter output to another AC source, such as the grid or a generator.

• Q: How can I activate the energy-saving function?
  A: Set the power switch I-0-II to position II [ECO] to activate the energy- saving function.

• Q: How do I connect a remote power switch?
  A: Connect a remote power switch to the dedicated 2-pole connector by removing the default jumper. Make sure the power switch is set to ON or Power Saving mode.

General Description

• WI800-12 and WI800-24 are DC / AC inverter, designed for off-grid applications, with high reliability and professional performance.

• The product was developed to produce a waveform of pure sine AC output, with high conversion efficiency, up to 94%, and very low power consumption in stand-by mode, less than 5W.

• These features are obtained through a hybrid configuration with toroidal transformer output and high frequency switching technology. (HF Technology)

• The energy saving function allows to reduce the consumption in a significant way in the event of lack of the connected load, ensuring a superior system autonomy.

• AC pure sine wave output

• Continuous power 800 VA Output voltage : 230V 50Hz

• Maximum inverter efficiency 94%

• Energy Saving Function

• Shutdown switch

• LED indications

• Battery voltage 12 or 24Vdc

• Sealed, liquid acid or lithium

• • IP20 housing

Protections

• Low battery
• Short circuit and AC overload
• Over-temperature

WI800-12 AND WI800-24 INSTALLATION GUIDE

1. BATTERY CABLES: the WI800-12 and WI800-24 inverters have to be connected to the battery with cables with a suitable section, in particular in the case of distance between the inverter and battery less to 1.5m or more but in any case within 3m, according to the following table;
2. BATTERY CONNECTION: configure your battery bank with voltage 12V for WI800-12 model, battery bank 24V voltage for the WI800-24 model, then connect the RED terminal to the POSITIVE of the battery and the BLACK terminal to the NEGATIVE of the battery; (WARNING: if you do not respect the polarity the inverter will be damaged permanently!)
3. AC CONNECTION: Connect the AC load user with 230Vac output, through SCHUKO standard connection; (CAUTION: Never connect the output of the inverter to another AC source, such as the electricity grid or a generator!)
4. POWER ON of the INVERTER : set the power switch I-0-II in position I [ON], perform the startup of the inverter and check the power supply of the user load; (WARNING: in case of overload for 3 times within 30 seconds, the inverter goes into automatic shutdown, for the restart is necessary to turn off the power switch, remove the cause of overload and provide with a new power on procedure!)
5. POWER ON of the INVERTER in ENERGY SAVING MODE : set the power I-0-II position II [ECO] switch, the power saving feature enables a reduction in power consumption in stand-by 70%, through the activation of the inverter for a short period every 2.5 seconds. The inverter switches to an activation status always ON for a load with more than 30W while turns into an energy saving status for a load with less than 20W;
6. RENEWABLE PLANT: if there is a plant of renewable energy production, connect the plant through a dedicated charge controller on the battery terminals. (WARNING: WI800 inverter battery cables should always be connected directly to the battery terminals!)
7. REMOTE ON / OFF : connect a remote on/off power switch to the dedicated connector with 2 poles removing the series closure jumper. (CAUTION: even the power switch must be set to ON or ENERGY SAVING)

MEANINGS OF LED INDICATIONS

From the front panel of WI800-12 and WI800-24 inverter, you can make the switch on and off of the inverter, you can also get reports about the working status and error:

Tab. 1 display LED STATUS – ERROR

WARNING : in case of LOCKED inverter, there is no supply voltage at the output AC-OUT, because occurred of one of the FOUR fault conditions specified in tab. 3, you need to RESTART the device, according to the following sequence

1. turning off with switch in position 0 [OFF]
2. wait for 2 seconds
3. new turning on with the switch in position I [ON] or II [ECO]
