I do about a hundred miles a day of garage sales on a motorcycle.
I put the booty in a box on the back end. When I get home,
it's not unusual to find a bunch of screws in the bottom of the
box that were shaken out of the stuff I bought.
I had an analog voltmeter in the back for a year or so.
When I needed it, I discovered that the insides were about the
consistency of a pile of sand. That's with an OHV twin engine
shaking the stuff.
You don't seem to have any charge control. I'd at least stick
a big SCR with a zener like a typical cheapo battery charger.
You wanna be careful about overcharging the expensive battery.
I'd get the component temperatures WAY down.
Reliability doubles for every 10 C you can get the temp
down. When the diodes fail shorted, there's a lot of
current that's gonna go somewhere you probably won't like.
Fast charging/discharging the battery/inverter setup might not be very
efficient and is hard on everything.
You might be trying to do too much with one system
and compromising everything.
Might be more reliable/efficient to run the big generator
for the big stuff and a 1KW generator for small stuff
on the battery/inverter system.
I have a Coleman PM500 generator. It's a 2-stroke PITA,
but it weighs 12 pounds as I recall.
Compare that to lugging around a big battery.

I have no ideal if the solar panel can take the vibration. I am going to find out. The solar panel is racked to the generator with rubber vibration isolators.
The battery is AGM, good vibration resistance.
I have a 30 amp Morningstar prostar PWM charge controller. I run solar and my home made 220vac powered battery charger through it.
