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

What is off grid system? Off-grid solar energy systems are also called stand-alone solar systems. It does not connect with Grid or called Utility. It is very popular and suitable for remote areas where there is no public power or Public power is instable.It can be for Home applications, Commercial applications and Industrial applications. The off-grid solar energy system can be 1kW/2kW/3kW/5kW/10kW/12kW/16kW/20kW/24kW/30kW/50kW/80kW/100kW/120kW/ 150kW/200kW/Customized off-gid power system Off-grid system is suitable for areas without grid-connected or unstable grid-connected power. Off grid system is usually composed of solar panels, connector, inverter, batteries and mounting system. Description of 15kW solar panel system: Inverter power: 15kW AC output voltage: AC110V/120V Battery voltage: DC24V or DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS
