WF Inverter/Solar Inverter (700W-40KW)

WF is the WD series update model, has wide power range of single phase solar inverter, smallest one can do 700W, biggest one can do 40KW. The inverter can choose with our without built in solar controller. If without built in controller, it can work like UPS. If with built in solar controller, it has PWM or MPPT controller optional, controller current can according to system request to matched. This series inverter also can work for different type batteries, like lead acid battery, deep cycle battery, gel battery, etc. Can choose with APP WIFI module, so easy to check the solar system data, like solar generate power, battery voltage, load percentage, etc.
