Default Recommendations Desired: Converter/Chargers

lesson #? (and many more to come, im sure).

I pluged into a 30a connection that had 120v across the ground...
I checked the plug w/ my meter (before i plugged in), but i only checked the 2 hot legs (not the ground - DOH!)

SMOKED (literally) the converter/charger

any recommenations ? and why you like 'em would be appreciated.
and yes i will be adding a surge / wiring protector !

I have the a iota converters in my rig. Twin 45 amps with the smart iq modules, they work well and a small footprint for mounting. Three stage charging.

TWIN charger/converters ? why ?
Ive got a <burnt> 55a in there now, seems plenty & ive got no plans to add more 12v accessories (if anything i wouldnt mind a couple of 120v a/c lamps (for situations like this).

i definitely want a good (built in) intelligent battery maintainer....at least 3 if not 4 stage charging....right now, when the coach is in storage i kill the charger/converter & use batteryminders to prevent overcharging of the batts.

footprint isnt too much of an issue, since the current mounting location is inside, behind a closet/drawer & the distribution panel/breakers...quiet is important though.

Don, I'm confused about how this blew out to begin with. The recepticle had 120v positive coming from the ground hole? That sounds crazy. How could that have happened?

With a good converter/charger, like what you got, it shouldn't be able to overcharge anything, should it? I wouldn't think you would need to use that battery minder. I've got an Iota 55 amp unit and that's all I use all the long MN winters for storage. I don't think it's been a problem for me.

the 30a outlet was either wired wrong or SHORTED.
the outlet had 120v on the ground and hot/blade - which gave me 240 volts.

i have an analog meter plugged into one of my 120v outlets in the coach, it was PEGGED after i plugged the coach into shore power & my Volt/Ohm meter showed 240v across the 120v outlets.

all my 120v outlets were recv'ing 240v....the converter recv'd 240v instead of 120v. i would have expected a breaker to trip or some (possible) internal over voltage protection to have "tripped" inside my converter/charger - but i only see fuses for improper battery wiring (not improper ac voltage).

MY MISTAKE -

i only checked the two BLADES on the outlet and had 126v, had i checked the ground i would have seen the ground also had 120v across it too.

a surge protector would have saved me from this ground fault/short (lesson learned). I consider myself lucky that i didnt burn anything else up (electrically or by fire).

That's messed up. I hope it didn't mess up any items plugged in, like tv, stereo, ac, etc....

the POS parallax 7455 that was in the coach (and filled 1/2 the coach & bathroom w/ SMOKE) was not a multistage charger...generally i only kept the house batteries connected when we were traveling or dry camping, when the coach was in storage i used battery minders to keep the batteries charged (and to keep them from being overcharged).

ive used battery minders for years on our motorcycles, and have NEVER over charged or boiled dry any batteries.

both flat screens, and the outside (3rd) tv, along w/ all (3) stereo's, the microwave, fridge, and A/C's are fine...amazingly enough.
