6500EX upgraded to EG4 18KPV Emergency install. What questions do you have?

We live completely offgrid and have had the EG4 6500EX system for nearly 4 years. After many failures we needed to do an emergency upgrade. This is the whirlwind upgrade to the EG4 18KPV that happened unexpectedly in order for us to resume power here at the ZR90 Ranch. #EG4 #offgrid #solarpower #EG418KPV
