The 5kw solar inverter is integrated with MPPT solar charge controller inside. It can also connect to grid to take grid as backup when battery is over discharged. The output voltage is 220V, maximum 6pcs in parallel. 3pcs in parallel can get three phase 380v output. All of parameter such as working mode, charging current, over discharge voltage can be set as you wish.

The 30kW off grid solar power system can be used for remote area without grid connection. Wifi or GPRS monitor can be avaible for such system.  Inverter power: 6pcs 5kw in parallel AC output voltage: AC220V/230V/240V or AC380V/400V/415V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatiable with generator Monitor: WIFI or GPRS

This is brand new three phase hybrid inverter with low battery voltage 48V, ensuring system safe and reliable.With compact design and high-power density, this series supports 1.3 DC/AC ratio,saving device investment.It supports three phase unbalanced output, extending the application scenarios.Equipped with CAN port(x2) BMS and parallel, x1 RS485 port for BMS,x1 RS232 port for remotely control, x1 DRM port, which makes the system smart and flexible.

This is a multifunctional inverter,combining functions of inverter, solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user configurable and easy accessible button operation such as battery charging, AC/solar charging, and acceptable input voltage based on different applications.

The 100kw off grid solar system is suitable for area where there is no public electricity or public electricity is not stable. It will be a good solution to supply power to the loads and decrease the electricity bill and fuel bill. Inverter power: 100kw power frequency inverter AC output voltage: split phase 120V/240V or three phase 208V or 380V Battery voltage: DC360V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with generator and grid

The off grid solar inverter can be put outside and work without battery. Both solar panel and grid are connected to the inverter, solar is priority, grid will be backup. It is very suitable for such situation: loads work at daytime, with grid connection. Electricity bill can be saved a lot. The inverter power range can be 5kw to 500kw.
