The 3kw off grid solar system is usually for home use where there is no grid or grid is unstable. It can supply power to normal home loads such as washing machine, LED lights, fan, air conditioner. Inverter power: 3kW 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

An on-grid inverter’s main job is to convert DC power generated from the PV array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. In the developing world, hybrid inverters are more of a necessity to compensate for weak or intermittent grids or a lack of grid electricity all together.

The 10kW solar off grid power plant is composed of solar panels, batteries, inverters and other accessories. This system can supply power to home loads independently, also it can be connected to grid or generator to take them as backup when battery is over discharged. Inverter power: 2pcs 5kw in parallel AC output voltage: AC110V/120V or AC220V/230V/240V Battery voltage: DC48V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly Compatible with grid and generator Monitor: WIFI or GPRS

This is a multifunctional off grid solar inverter, integrated with a MPPT solar charge controller, a low frequency pure sine wave inverter and a UPS function module in one machine, which is perfect for off grid backup power and self-consumption applications. This inverter can work with or without batteries. The whole system also need other devices to achieve complete running such as PV modules, generator, or utility grid. The wifi/GPRS module is a plug-and-play monitoring device to be installed on the inverter. With this device,, users can monitor the status of the PV system from the mobile phone or from the website anytime anywhere.

Such hybrid solar system can work as both solar on grid system and solar off grid system. It can utilize electricity price difference, charge battery at low price and discharge at high price to maximize system profit, compensate local transformer limit. It can  provide back-up power supply for unstable grid, during grid failure, seamless switches to off-grid mode within 20ms to realize uninterruptable supply

The solar photovoltaic power system connected to the public grid is called on-grid photovoltaic power generation system.
