What's wrong with normal RV batteries recharged by portable solar panels and a $100 controller? And what good is a micro system? Either your RV batteries (or "generator") are recharged or they aren't. If they aren't recharged you need more panels, a sunny day, a better location etc.
Portable panels need to be stored somewhere during travel. PWM controllers aren't very efficient. But even so, I'll probably get some portables too, for extended boondocking trips.
Micro systems are good if you need to power devices in a tent, for example.
Normal batteries? I assume you mean Flooded Lead Acid? The problem with FLAs is the limited depth of discharge, the weight, the energy density is low, it takes longer to charge to full and the lifespan is shorter.
I have gone from FLA to AGM to LiFePo4 and I will never go back to the first two. I've been boondocking for a month now and haven't fired up the generator once. Before I upgraded my battery to LiFePo4 and my panels from 90W to 300W we had to fire up the generator every day for a couple of hours to meet our energy needs(or drive most of the day).
Ask me anything.
