2008 25' - Trailer has been sitting for about a month. Replaced my gopower PCM solar charge controller with a victron 100/50 unit the other day - straight swap. Now I can read solar charging state and voltage on my smartphone - yeah.
Now comes the funky behavior in the trailer... (may or may not be related) I am in the trailer on battery power this afternoon (12.8v showing on the victron) playing the radio with sub woofer and have a dozen LED lights on... run the faucet and the water pump kicks in. After a few moments the LED lights start to dim/flicker. Then all of a sudden all 12v
power goes dark / turns off. click. A second or 2 later the power comes back on, radio turns back on, internet router reboots, pump kicks back on, etc..
Let the trailer sit a while, went back in tonight. Turn everything back on, showing ~12.5v on the victron (cold out) and same behavior... lights flicker a little / dim and power cuts out after the pump runs for 10 seconds or so.
Again, I am on battery power (not shore power) so the converter is not in play. no fuses are tripped.
I am thinking I may have a bad battery disconnect solenoid switch perhaps? Perhaps it doesn't think it is seeing enough voltage all of a sudden and automatically shuts down the main 12v
Batteries are 2 group 27 lifelines installed about 5 months ago.
I boondock about once a month and in 8 years have never had this happen before.
I'm going to juice of the batteries overnight on shore power and see if I can reproduce in the am... in the mean time -
