My understanding is the same as William's that my total back feed value is based on the over current devices for each inverter which is 40 amps X 4 = 160 Amps. Where I'm having a problem is choosing a panel based in respect to considering both the inverter feed and the utility side or just the inverter feeder side. Considering just the feed of the inverters is certainly preferable as Mark suggests since that would allow for use of a 200amp panel. My take on it in that respect is a 200 amp panel, with no additional slots other than those for the 4 inverters with clear signage that no load circuits are permitted in this panel. A second small panel would then be employed if any load circuits were required for lighting or monitoring devices. Thanks Rich
