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

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 solar photovoltaic power system connected to the public grid is called on-grid photovoltaic power generation system. The system structure includes solar panel arrays, DC/DC converters, DC/AC inverters, AC loads, transformers, and other components. Inverter power: 20kW AC output voltage: three phase Solar panel type: mono or poly
