Evaluate my electrical
Now I've done pretty much everything myself (with a little oversight on the tricky stuff), so bare with me.
I have a 125 amp breaker box, with 6 switches, four 15 amp breakers for outlets/lighting throughout, one 30 amp breaker for a rooftop AC, and one 30amp breaker run to an outlet in my storage area for power tools (converted bus chassis, back was used as a walk in horse trailer for my sister, sits about 2 feet lower than bus body but rear air keeps it high when driving)
On top of that I have 300watts of renogy solar coming in, with a 30 amp charge controller/batter monitor.
I also have a AIMS 2000w inverter with a 70a charger built in, it can handle surge of 6000w for 20 seconds allegedly. This thing seems too smart for its own good so far... Lol
I have a champion 3100 watt inverter generator ( plugging in 30amp shore cord into 30amp plug to power RV AC when not on shore)
My battery bank is two 225amp hour batteries wired to make 12v. I do plan on dramatically increasing the bank size in the future.
But, for now between solar charging/inverter/generator I might be good.
My question is, Is it worth it for me to run a smart isolator to the alternator as well? I have a 140amp isolator which should suffice before I get a new alternator in stage 2 of the beef up. Can I get by with the solar/generator/shore power charging without needing the alternator?
My needs on the inside of the bus are: 120v water pump, 4.5 cf mini fridge/freezer, phone/laptop charging occasionally, and led rope lights. Food will be cooked off a small George foreman, stove top, or the grill I'll bring along in my back storage. My Coleman Mach RV AC draws at 14-15 amps and surges pretty high, I plan on only running that when necessary off the generator or shore power.
I'm having trouble with the air conditioning load going through the inverter, initial surge it handles with ease. But, when it kicks later on it struggles. My guess is the wiring from battery bank to inverter is too low of a gauge, I might need to run 0 or 1 gauge for the connection. I thought to run the AC I could just turn off the inverter, but I think I'm missing something with that guess.
The desire for the run off the alternator is because I'm 21 years old and my girl and I are going on a 5 month national parks pass trip across the USA before law school starts. And so much driving it feels silly to waste it.
Thank you guys for your help already on my previous posts, it means a lot!
