The converter or inverter has little to do with tripping the 30A breaker. The breaker trips when the amps get too high and the amp draw via the converter/charger is quite modest. Probably no more than 2-4 amps.
If this only happens in the rain, then most likely something is shorting. Could be an exterior outlet on the RV, or water leaking somewhere inside the RV, or somewhere along the shore power cord.
Mr. Wizard I'd like to ask several questions... (pick your brain a little if possible)...
HOW TO GROUND PROPERLY WITHOUT USING CHASSIS?
rv electrical items i have:
100w solar panel w/100a mppt controller, 2k rms 4k peak 120v inverter, 2 farm style cold weather batteries about 75Ahrs each(MIN. 900CCA), ( will be adding 2 agm types on separate circuits for hotplate as money permits, then using inverter only for high watt items WITH THOSE and mppt controller for interior lights, small electronics on current batteries)...these batteries are not really RV batteries(lead acid); but they have similar chemistry composition "thicker plates" so they charge quick and discharge quick; but are not sealed so I have them separated in a ventilated box away from living areas.
So OK...
I'm building DIY a van camper, and have slight electrical knowledge from setting up stereo systems and such. But 120v and 12v confuse me a lil as to the step ups and step downs when powering inverters... and with that I know that you have to properly ground to avoid excess current going back into the components or yourself through any metal or connected devices that you may touch... So
What I need to know is: HOW TO GROUND PROPERLY WITHOUT USING CHASSIS?
1) how do I properly ground my electrical setup to provide extra recharge boast when overcurrent is presented thru wiring, not just to waste it in a chassis ground or make the chassis "live" by grounding the inverter to it. the inverter is a 2k continuous 4k peak from harbor freight and has a earth ground it seems, the fork with 3 poles on it. can I send that ground back to the negative of the primary battery or should it be the non inverter connected battery in the bank? Since the batteries are connected to the inverter producing 120v alternating, isn't a lot of the energy being sent THROUGH the components and not being directly used, forcing the inverter to heat quickly? Would a ground back to battery help cut energy waste?
CONVERTING STARTER TO AC GENERATOR
2) do you have any tips on converting a starter magnetic core into a generator. I am about to buy a new stator for a salvage starter I've cleaned and checked. It seems to be rather good after de-oiling... but i need to make sure that my poles and magnetic field are ok. I have volt/ohms meter but its the old needle gauge kind so testing is a bit skittish. What's the best wiring for this? Basic assembly is where I think i can put it together as far as the actual components.... starter body and stator coil / pulley on dc fan spindle connected to small battery / pulley fitted to starter spindle using belt similar to car fan belt for durability / all fastened into a apc power supply case enclosed in 1/4 in thick wood shingles, covered by thick foam rubber matts. Does any of that make sense? How/What is the BEST WIRING TO GET 120V AC from this.... I've seen it done on alternators being tapped for AC, and now the newer ones have tap screws built in but are rather expensive. Can you suggest / reply with link to a diagram to follow?
Sorry for the long-windedness Mr. Wizard; but I hope you understand my attempted configurations here. Please fill free to reply as time permits. I can also load pics of components if need be.
THANKS IN ADVANCE FOR YOUR ASSISTANCE!!!
