Same up here in the southern sierra. I get calls from ABB and a few from SMA to look at systems that people far away installed and as a local 3rd party it can save some money. Whatever they quote me I triple the price. 1/3 up front and the rest when it is done. ABB is really slow with payment. I think they sold their inverter business? Sunpower is a great panel but they have had some bad runs. Probably why there are so many new/used panels on the secondary market. They are great for Offgrid ground arrays and no AFD.

We tell them that a system is arc faulting, and then they insist on sending up a 3rd party contractor to inspect the system and potentially install what they call "Tigo Diodes". I am still not exactly sure what that is. It also seems to take them months to send anyone to upstate NY, as we have a bunch of customers that have been waiting months for the 3rd party contractor to come take a look. You likely could only follow this route though if the system was installed by a Sunpower dealer and you are a Sunpower dealer yourself. If the original system was from a Sunpower dealer, you can also have the customer call Sunpower directly.

We were told by our SMA friends that a firmware update/fix was forthcoming in mid-August and we've heard nor received nothing last month. Does anyone know anything as to where they're at on this?
