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.

such on grid solar system is usually for home use. Solar panel will be installed on the roof, solar power will support loads first, the excess power will be sold to grid. If the grid does not allow feed in function, one limiter can be installed. The output of 15kW/20kW is three phase.

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

The 80kW off-grid solar system is suitable for commercial power stations. It has an intelligent power generation platform and energy storage system. It can be compatible with generator to save fuel bill. Inverter power: 80kW power frequency inverter AC output voltage: AC120V/240V split phase or three phase 208V/380V Battery voltage: DC360V Battery type: Gel battery or LiFePO4 battery Solar panel type: Mono or poly
