Solar trickle charger fail!
It's a 10W solar trickle charger. Found my dual battery down to 9.6V and can't operate my powered jack. Good I have my spare battery, for my kayak motor, that saved the day. My 100W Renogy so...

Is your 10 watt panel going through a controller? If so at the best you get a bit less than one amp and if you have a big battery in an RV parasitic loads and self discharge can be more than that.
Also unless there is some kind of reverse current protection (There is in the charge controller) the 10 watt panel takes 'em down in the dark.
The bigger panel likely was used with a charge controller. possibly an MPPT (Maximum Power Point Transfer) these are DC/DC converters that swap volts for amps so you get the maximum power from your panels. they also contain reverse current protection So at night. they "Vanish" electronically
The 10W trickle charger is not going to a controller.
The 100W is.
So, do I get it that the rate of discharge from phantom drain from the RV is higher than my rate of charging on the 10W solar trickle charger?
Again, thanks everyone for the information. I'm buying a battery disconnect switch.
