5 Working Mode of 8kw Solar Inverter(intelligently & automatically transfer to different mode)
PT series IGBT design transformer based solar power inverter has two working mode:DC Priority and AC Priority
5.1. DC Priority (PV can support loadings without battery bank)The inverter converts DC input current from either the PV panels or battery bank into ACcurrent to supply the loads. When battery voltage is low, the inverter will automaticallyswitch to the main input power (gr/generator) to supply power to the load. The systemautomatically switches back to AC after the battery are charged again.
(1) PV with battery bank
(2) Battery only
(3) Only AC power
5.2. AC Priority
While the AC input is stable, the inverter works in the bypass to supply power to the load and charges the battery pack at the same time. When the AC input is too high / too low / serious distortion / abnormal frequency / fault, the system will automatically switch to the battery inverter to supply power to the load. Once the AC input has been stabilized, the system will switch back to the bypass mode to supply power to the load automatically.

(4) Battery only
