A non Smart solar inverter treats all household loads including Electric vehicle equally. The real time capability of the solar inverter to deliver maximum power to the electric vehicle is called PV Optimised. This model cannot charge an Electric Vehicle (EV) in a PV optimised or forecast based manner, when solar power should feed the car and not the household loads. Select in [pathtogreenhomes.com] (pathtogreenhomes.com). The best EV charging solar inverter with PV optimization capability.
A non smart solar inverter treats all household loads including Heat pump equally. The real time capability of the solar inverter is to put last priority as the heat pump , with excess solar power used for space heating or space cooling .The priority of smart inverters shoud be as follows 1st EV, 2nd household loads , 3rd battery charging and lastly heat pumps. . This Delta model cannot communicate with a smart grid ready Heat Pump. Select in [pathtogreenhomes.com] (pathtogreenhomes.com) the best Heat pump- compatible solar inverter
