Wrenches,
A longtime off grid customer with a 1997-era Trace SW4024 and a
Kohler 8.5RMY backup generator (with 1,800 hours over 16 years) has
never had an inverter failure, but requested my assistance with a
recent development. His generator has been set up on automatic
I thought the relays on the SWs were sealed, so visible arcing sounds
bad. Are you sure its not a loose connection?
Also on the batteries, anytime I've ever seen someone replace just a
couple of cells in a bank that old, it never ended well. It was like

years, even with keeping a close
I've not had good luck on Surrette 5000s actually. We had a set that
was really problematic early on with battery voltage temporarily
