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.
The solar power inverter is highly integrated with the digital technology, which can improve the MTBF and reliability of the system, the whole systems are controlled by an independent high-speed DSP chips which can ensure the stability and reliable operation. Optional power: 40kW 60kW 80kW 100kW 120kW 150kW 200kW Battery voltage: DC192V/DC216V/DC220V/DC240V/DC360V/DC384V Battery type: Gel battery or Lithium-ion battery AC output voltage: three phase 208V or 380V/400V/415V
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.
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.
