Solarpals:
My brother has a 14 year old Sun Power system with 24 panels and a Sun Power inverter made by SMA. The system requires an inverter that can handle panels that use a positive ground. Apparently modern inverters cannot do that. He contacted SMA, and they cannot service it and apparently do not have anything in their current lineup (hey nice pun) that will fit the bill. I saw this inverter on Ebay SunnyBoy 4000TL-US-22 and wonder if it can do the job. None of the inverters I have looked at seem to list ground capabilities. Thoughts here? Sun Power cannot help him either. They just want to sell him a new system.
