Re: Inverter/Transfer Switch
Ready, Fire, Aim!". 3 kw from 12 vdc is is ~250 amp. We really suggest you look at a 24 or 48 vdc system, as the battery wiring is simpler, the wiring more efficient, and more importantly, if you are going to drive 3kw out of 12 Volta you are gng to need a huge battery. I suggest, as did 'Coot, get a better handl on the loads. All design considerations strt with the loads,, all else is R,F,A!
My hunch is that if this guy is power hungry and uses a 7 kw genny, he is going to use all of the 3 kw of the inverter, and likely kill his batteries in the process. What on earth does one need to run in a Cabin that requires 7 kws or 3 for that matter. remember, cons action is a cheap lesson, as if he can reduce his loads, both total and peak, he will be able to buy a much better system, much cheaper.
Please note, being a moderator does not add any weight to my opinions 300 watts Siemens/BP panels,plus a Sun 90,, making ~400. ~30 amps into Rogue MPT-3024, 450 ah of Trojan T-105, Morningstar ts300 inverter, a Tri-Metric meter.a collection of antique generators, plus 2 Honda eu-1000i's (also a BS2512 IX controller) and assorted other stuff!
