One would think that after 40 years off grid, I would have seen everything. But.......I have inverted for 28 years with a Trace SW 4024 inverter. Recently, a lightning strike near my PV system rendered my old trusty Trace unable to charge. (Inverter to 120 V was OK)
I decided to purchase another used Trace SW 4024 because I was familiar with it. The replacement works great except during charging from my P9500 df ONAN/CUMMINGS generator. Within 30 seconds of "charging" the Trace's DC Volts meter reads 28.0 V. My Outback 80 controller also reads 28 V and multi tester on my series lead acid batteries reads 28 V on all 5 series. When I turn off the generator, the battery voltage drops slowly back down. The final voltage is dependent on the voltage present when charging started.
My old Trace charged the batteries as expected (a slow climb) for 28 years.
Your thoughts are appreciated in advance.
