Moisture in Inverter
I've got an SMA SB5000TL-22 inverter in a client's basement that has moisture beading up behind the glass window in front of the LCD screen. My techs plugged the conduit going to the outside, so there's no way moisture is getting in that way. The inverter was replaced once, on the assumption that the seal might be bad on the black plastic face plate, but the problem also occurs on the new inverter. My only idea is opening the spare conduit inlets on the bottom of the inverter and or putting desiccant packs in. Alternatively, I may just recommend the customer purchase a dehumidifier. Anybody else got any better ideas? SMA was no help.
