okay update, got a second hf 35 amp battery.
tried the micro wave again. no dice. still not showing overload. think its out, or the wave form of the everstart is just too bad.
update on the ac uint. its a kenmore 5000 btu. still haveing hot restart issues. i can run the ac non stop. but restarting i cant do. on the odd side, the 'low fan' setting consumes 75 watts, the 'high fan' setting consumes 55. go figure. the ac running is pulling 300 watts. next up is a hard star capicotor since its the restaring thats a problem. that should help. also, im going to convert this to use 12v fan, elilminated the that 55 watts the fan uses. most of the noise is the fan anyways.
id like to use twin inverters anyways. one for the refridgerator, one for everything else. not really needed, just more of a back up. im planning to spend the whole summer in this, so figure april to october or so. ill be starting off with 200 watts solar, and maybe 400 if i can fit it on the trailer. ill be getting less that that, due to the angles, but it should flatten out the 'sun curve' , ill get less amps all at once, for trading if for a but more in the morning and afternoon assuming i park east to west. still working on an additional 100 watts on a sun tracker i can set up.
one thing a life time of camping has taught me, 1 i hate generators. 2, i need power. always rununing out of power and haveing to use the car.
ill probably end up getting a HF 800 watt generator and a ton of 15v 90 watt laptop power supplies to feed into the solar controller when the sun is not out.
im giving up on building one, for now anyways. with out any way to check SOC, i might was well use the el cheapo ebay 20 amp charger.
once i star gettting the lifepo4, ill guild a charger for that. those are alot eaiser to work with. paralleling the batteries shouldnt be an issue, relays to take them out of the bank to check the volatge, and a a shunt on each to keep track of how much im pulling. an arduino to run it all. ill be neediing an external ADC, one with an intigrated op amp to read the stupid low 75 mv full load shunt.
but that willl come later.
since i got a 3d printer, ill be trying to make a wind genrator. 50 watts or so on n42 15mm x 4mm neo magnets. but one thing at a time. first off the lead acid solar set up. three 35 amp hf batteries. the rest and come later.
mostly i need the refridgerator. on 70 amps i can do it. its an dorm fridge converted to ice chest (not sure if its worht it. draws twice what id did. lol) cooling has always been the problem camping.
the micro wave would be nice, but i guess i can do with out. and ac is pretty much a must, even if i got to shell out for a honda 1000eu gen.
well thats it for now. time for sleepy stuff!
