In reply to Nic Westhuizen. The purpose of inverter is defected if it still need power from the grid

More and more electricity companies are banning Grid tie solar systems. In our case even if you set your inverter to Zero Sell back / feed in, the power company still doesn’t allow the system. Without using expensive batteries the only other solution is a GRID ASSIST inverter that allows an AC input on the Input to the inverter and then supplement the solar energy with AC/Grid power in an event where solar is insufficient or absent. This inverter can then be plugged into a wall socket and connected in line with the load,(i.e. pool pump) thus no approval from the power company is needed. Unfortunately there are not many of these GRID ASSIST inverters on the market. Can this smart inverter be programmed to act like a GRID ASSIST inverter?

I guess it’s time for me to replace my ASi MSX-43w and Omnion 2200 inverter with a better PV array after 20+ years

We need someone to make smart microinverters now. The inverter guys are on the job, but the microinveters manufacturers are grossly late.

C’mon guys, get smart. (Hoymiles, Deye, AP Systems, Lead Solar, NEP, Darfon)

I would just mention that it is most commonly referred to as the 2017 NEC rapid shutdown requirement in the rest of the country.
