PV Module Selection: (Only for the model with PWM solar charger)

When selecting proper PV modules, please be sure to consider the below requirements first:

  1. Open circuit Voltage (Voc) of PV modules does not exceed the max. PV array open-circuit voltage of the inverter.

    Rated Out Power12V24V
    Charging Current (PWM)50Amax.
    Max. PV Array Open Circuit Voltage55Vdc80Vdc
  2. Max. Power Voltage (Vmpp) of PV modules should be close to the best Vmp of inverter or within Vmp range to get the best performance. If one PV module can not meet this requirement, itS necessary to have several PV modules in series connection. Refer to the below table.

    ModelBest VmpVmp range

Note: * Vmp: panel max power point voltage.

The PV charging efficiency is maximized while PV system voltage is close to Best Vmp.

Maximum PV module numbers in Series: Vmpp of PV module *Xpcs = Best Vmp of Inverter or Vmp range

Mounting the Unit

Consider the following points before selecting where to install:

  • Do not mount the inverter on flammable construction materials.
  • Mount on a solid surface
  • Install this inverter at eye level in order to allow the LCD display to be read at all times.
  • For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the side and approx. 50 cm above and below the unit.
  • The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
  • The recommended installation position is to adhere to the wall vertically.
  • Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.


Battery Connection

Battery Connection

CAUTION: For safety operation and regulation compliance, it金 requested to install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in some applications, however, it% still requested to have over-current protection installed. Please refer to the typical amperage in the below table as the required fuse or breaker size.

WARNING! All wiring must be performed by qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for battery connection, lb reduces risk of injury, please use the proper recommended cable and terminal size as below.

Please follow the below steps to implement battery connection:

  1. Assemble battery ring terminal based on recommended battery cable and terminal size.
  2. 1.5KVA model supports 12VDC system or 24VDC, 3KVA model supports 24VDC system. Connect all battery packs as below chart. It台 suggested connecting at least lOOAh.
  3. Insert the ring terminal of the battery cable flatly into the battery connector of the inverter and make sure the bolts are tightened with a torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly

AC Input/Output Connection

CAUTION!! Before connecting to the AC input power source, please install a separate AC breaker between the inverter and the AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 10A for.5KVA,32Afor 3KVA.

CAUTION!! There are two terminal blocks with ''IN" and ''OUT" markings. Please do NOT disconnect input and output connectors.

WARNING! All wiring must be performed by qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce the risk of injury^ please use the proper recommended cable size as below.

Suggested cable requirement for AC wires



Torque Value



0.5~ 0.6 Nm


12 AWG

1.2~ 1.6 Nm

Please follow below steps to implement AC input/output connection:

  1. Before making AC input/output connection, be sure to open the DC protector or disconnector first.
  2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
  3. Insert AC input wires according to polarities indicated on the terminal block and tighten the terminal screws. Be sure to connect PE protective conductor (@) first, k—Ground (yellow-green)

WARNING: Be sure that the AC power source is disconnected before attempting to hardwire it to the unit.

4. Then, insert AC output wires according to polarities indicated on the terminal block and tighten terminal screws. Be sure to connect PE protective conductor (®) first.

5. Make sure the wires are securely connected.

CAUTION: Important

Be sure to connect AC wires with the correct polarity. If L and N wires are connected reversely; it may cause utility short-circuited when these inverters are worked in parallel operation.

CAUTION: Appliances such as air conditioners are required at least 2^3 minutes to restart because it's required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check the manufacturer of the air conditioner if it勺 equipped with a time-delay function before installation. Otherwise, this inverter/charger will trigger an overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner.

Inverter works very well, charging current from the grid is 30A as stated. Running on off grid photovoltaic system there is important that when we have lack of sun in the winter, charging from generator will be fast. Tested all features including connecting to PC, the only thing is that there should be USB output, not RS232, who use it on modern computers.... But this has been solved very easy with simple RS232 to USB converter for 2 euro. No load consumption when 230v output is on is circa 1,1A, when it is off it is only 10mA. When there is voltage on photovoltaic input, display is turned ON and it it drains from the battery 250mA until there is enough power from solar panels. Than starts charging battery from photovoltaic source. Very good product for the price, i recommend it! Fans start when photovoltaic input exceeds circa 300W or load in 230v from the battery exceeds 400W. Tested on room temperature

Did not twist the 2nd fan, made a mistake and did not start. Pressed it on the wing, she clicked and stood up. After that, everything worked fine. I liked the device. Not very noisy. Although the fans blow powerful. Charging from the network 30A.
