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

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.
