mppt solar charge controller 192v-540v

The off grid solar inverter can be put outside and work without battery. Both solar panel and grid are connected to the inverter, solar is priority, grid will be backup. It is very suitable for such situation: loads work at daytime, with grid connection. Electricity bill can be saved a lot. The inverter power range can be 5kw to 500kw.

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 solar Multi-split 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

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.

LV-BAT-R5.12Aa is a lithium battery with an operating voltage range between 45.6~56.2V. It is designed for residential energy storage applications and works together with a low voltage hybrid inverter.LV-BAT-R5.12Aa is not suitable for supporting life-sustaining medical devices. LLV-BAT-R5.12Aa ihas built-in BMS (Battery Management System), which can manage and monitor cells information including voltage, current and temperature. Besides that,BMS can balance cells charging to extend cycle life.BMS has protection functions including over-discharge,over-charge, over-current and high/low temperature;the system can automatically manage charge state,  discharge state, and balance state. Multiple LWBAT-R512Aacan be connected parallel to expand capacity and power 15 LV-BAT-R5.12Aa can be connected in parallel at most

The on grid solar power system converts the solar energy into electrical energy, without the storage battery, and directly sends the electrical energy to the grid through the grid-connected inverter. Inverter power: 10kW AC output voltage: three phase Solar panel type: mono or poly
