I didn't ask if 120volts would be enough in storage tuna. I asked if it was ok to leave the batteries connected in storage or disconnect them. (cycles was my concern, didnt know if constant trickle was better than just letting them sit with no load).
An energy audit is pointless. This is my first trailer. I've never used it. Ive already told you want I want to use. Furnace in the evenings and morning and laptop charger and a few leds. It doesn't require an audit to figure out thats a low number of amp hours each night.
MPPT is unnecessary from my research. I am trying to work on a budget here. For the cost of MPPT it is better to simply use a PWM controller and buy another panel.
