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 charger is an AC to DC charging module. It has the advantages of wide constant power voltage range, high efficiency, high power factor, high power density, minimal electromagnetic radiation and interference, and high reliability to meet the fast charging needs of various batteries. ,Energy saving and environmental protection.

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.

Flexible solar panels differ quite from rigid, rectangular, glass-encased standard solar panels typically found on rooftops. Rather, flexible solar panels come in all shapes and sizes and are expected to be used in a greater number of situations than standard panels Whereas portable solar panels contain solar cells mounted in a lightweight, often plastic frame and thin-film panels are made of materials like copper, selenium, and gallium, flexible and standard solar panels use solar wafers to convert sunlight to electricity. Most often, flexible panels use wafers made from silicon, though they are far thinner than those in standard panels-as thin as merely a few micrometers in width. Whereas standard panels are sandwiched between layers of glass, flexible panels are placed between layers of protective plastic.
