I have a Solar City system that Tesla shut down remotely months ago because, according to them, it has faulty connectors between the panels which can short and cause a fire. This confuses me, because they shut off the inverter. I called and asked the rep on the phone that if the inter-panel connectors are bad, what does shutting off the inverter do to protect from fire? The solar panels are producing DC power whenever the sun hits them, if the connector shorts there is the same potential there if the inverter is off or on. I asked to have this explained to me but they have not offered anything that makes sense. Can someone explain to me how shutting off the inverter will prevent a short that happens up between the panels, before the power even gets to the inverter? It seems that if the connectors between the panels are faulty, the only way to prevent a potential short related fire is to cover the panels. Not shut off the inverter, which is way downstream of that. Only thing I can think of is if the inverter is off, there is no current flowing through the connectors (less heat, and therefor less likely to deteriorate further) but if they short anyway, the full current available is going to flow through them anyway.
Also, they said the estimated repair time is 300-400 days, which I think is rather extreme, especially if this is dangerous enough to shut the system down. And if that's not bad enough, they are charging me random amounts of money, between $19-$38 per month for the privilege of having a unusable system on my roof. They could not explain why the charges vary if the system is not producing.
Anyone have had an issue like this?
