My 2006 2100w Sunny Boy inverter is dead. I'm confused about what inverters can replace it. I have a 2000w array, ten 200w panels wired in two sets of five panels.
A new Sunny Boy 3000w inverter is $1500 or more, that should work. But I'm seeing Chinese inverters for $400 to $800. SunGoldPower connects to the grid at 120v, not 240v. Does that mean that their inverters can't sell power back to the grid in the United States?
This 2000w inverter
is $407 without the limiter that stops the inverter from selling power back to the grid (?). I'd have to hire an electrician to rewire the panels into five sets of two panels (which would improve partial shading performance). Plus the inverter has to be indoors, I'd have to have an electrician move the wiring from where the Sunny Boy is outside.
I bid on a used Sunny Boy 2500w inverter on eBay: https://www.ebay.com/itm/334534269348. With luck I'll get it for under $400 with shipping.
The installer made several major mistakes. The result is that this $25,000 solar array produced $1850 of electricity before the inverter finally died. (I paid less than $4000 after the subsidies.) I want to get the solar panels working again for as little money as possible before I tackle the major problem (moving the panels from the shady south section of the roof to the sunny north section). I'm fine if a used inverter only last a year or two. That will give me time to fix the big problems with the solar panels and then I can think about buying the latest, greatest inverter (and whether I want to add more solar panels, batteries, etc.).
