Wrenches, I'm dredging up this subject again (previous postings 6/08) with a simple question that doesn't seem to have been answered:
Is there any issue connecting a batteryless grid-tie PV system to the load side of a panel that is backed-up by a generator on an automatic transfer switch, when the grid is down and the generator running? In this case the PV is 5.7kW, the inverter an SMA 6000, the generator unknown size/type, but propane, automatic start, and backing up the entire main panel. SMA tech support first said it's OK, then that the generator will blow up. I can imagine, if the inverter tries to sync with the inverter, that the voltage could rise, causing the inverter to disconnect, wait 5 minutes, repeat. Is there anything nasty that could happen?
