3KW 4KW 6KW Off grid Hybrid Solar Inverter Specification
3KW 4KW 6KW off grid Solar Inverter is a multi-function inverter/charger, combining functions of inverter, solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurableand easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.
The 3.6kw inverter can work with 24V battery and there are also models with 48V battery. The 4.2kw and 6.2kw inverters can only work with 48V battery. The 4.2kw and 6.2kw inverters can only work with 48V batteries. If your utility power is relatively stable and the main use of electricity is during the daytime, not having batteries can save the investment in the PV system. However, we still recommend adding a small number of solar batteries, which will make the output of the system more stable.

3KW 4KW 6KW Off grid Hybrid Solar Inverter system introduction
The following illustration shows basic application for this inverter/charger. It also includes following devices to have a complete running system: Generator or Utility and Solar Panels
Consult with your system integrator for other possible system architectures depending on your requirements.
This inverter can power all kinds of appliances in home or office environment, including motor-type appliances such as tube light, fan, refrigerator and air conditioner.

3KW 4KW 6KW Off grid Hybrid Solar Inverter Features
Built-in MPPT: The inverter has a built-in MPPT with an efficiency of up to 98%, which reduces the losses during the battery charging process.
Dust-proof net design: The dust-proof design prevents dust, flying insects, and small animals from entering the inverter. Reduces the probability of damage to the inverter’s circuit board.
Multiple Protection: The inverter has over-voltage, overload and over-current protection to ensure the safe and stable operation of the PV system.
Smart chip: Intelligent algorithm provides multiple modes of output to optimize the conversion efficiency.
Intelligent charging mode: You can set the battery charging mode in the inverter, you can set the charging priority among PV and utility.
Pure wave output: The pure sine wave output of the inverter can be adapted to more household appliances, and appliances that have strict requirements on the output waveform.
Wifi/GPRS monitoring function: You can monitor the PV system remotely by cell phone or computer. You can know the power generation situation of the PV system anytime and anywhere.
Solar independent load function: the off-grid inverter can work normally even when there is no city grid. Provide stable power supply for off-grid living.
Small and convenience: 3KW 4KW 6KW inverter is 42*35*11cm in size and weighs only 10kg. It doesn’t take up a lot of space and is easy to install.
