mppt solar charge controller 192v-540v

The 5kw solar inverter is integrated with MPPT solar charge controller inside. It can also connect to grid to take grid as backup when battery is over discharged. The output voltage is 220V, maximum 6pcs in parallel. 3pcs in parallel can get three phase 380v output. All of parameter such as working mode, charging current, over discharge voltage can be set as you wish.

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. 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

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

Off-grid or hybrid optional 6KW inverter, Max 3pcs in parallel Grade A battery cells, up to 6000+ cycles 5.5KWh battery, Max 12pcs in parallel Easy to install, combined freely BMS & battery capacity auto-sense WiFi/GPRS remote monitoring (optional)

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 energy storage inverter can be used for both on grid and off grid solar systems, it integrates controller and inverter. During the daytime, the PV array generates electricity to provide power either to the loads, or  to the grid or charge the battery.  The battery can be charged either by PV power or by grid, the power stored in the battery can be released whenever the loads require it.  Moreover ,the inverter can give three phase unbalanced output accroding to set up, to make a most flexible power solution.
