mppt solar charge controller 192v-540v

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 10kW solar panel system: Inverter power: 10kW 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

The solar hybrid AC/DC air conditioner can work without battery, it works with unstable solar panel DC power at day time. At night or rainy days it automatically get grid AC power. It's  mainly used for school classroom, hospital, restaurant, shops, office… With APP monitor and control function through WIFI

The 50kw off grid solar system is designed for farm or hotel use. It can compatible with grid or generator. Solar is priority, gid and generator will be on standby mode. Inverter power: 50kW power frequency inverter AC output voltage: Three phase 208V or 380V Battery voltage: DC220V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly
