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.
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
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.
The 3kw 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 120V, several pieces in parallel can get 120V/240V split phase. All of parameter such as working mode, charging current, over discharge voltage can be set as you wish.
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
