Larry –
My immediate thought is that you would need a listed grid tied inverter designed for the purpose of connecting to this type of battery and inverting to the grid. A regular PV inverter won’t cut it since it is designed to MPT PV modules. The SolarEdge StorEdge product sounds like the closest thing on the market that might be close to working. But, once again, it needs to be setup to work with your particular battery. I think StorEdge is planning on working with Tesla and LG Chem RESU batteries in the 350 to 400 v range.

They have an existing grit tie system. What they want to do is connect a 5kW grid tie inverter to their 340 volt, 32kWh EV battery bank and feed the grid to discharge the battery. Why was not discussed but sure bugs me. My uneducated guess is the inverter will be immediately damaged. My thought is how would it limit the input current? Or, is there such an inverter available that can do the job? Any input is appreciated. Larry Crutcher Starlight Solar Power Systems
