"I ran a 12v system until recently (8kw 12v inverter- and thats not a misprint- 8000w at 12v"
That's some serious stuff!
That's soem good ideas with using reverse LED truck lamps, didn't even think of that, so thanks.
"What I use are LED bulbs that fit standard ES light bases- so can be used in any 'mains' fitting- but running directly from the battery bank"
That's the way I went too (E27 base with ST58 and ST64 globes), for the lounge and kitchen anyway.
Much more to choose from with respect to good looking hanging pendants etc available only for AC general house use.
"BTW a warning for people- do NOT use AC breakers on DC- even at voltages well under their ratings- they can (and almost certainly will over time) arc weld shut- not something you want to happen to the safety cutout!!!!- us DC rated breakers- again readily available"
Absolutely and good advice!
I decided on non-polar DC breakers.
Wanted one non-polar breaker for the link between MPPT and battery and decided to
purchase direct and in bulk from manufacturer in China a set for whole system.
I did find it dificult to source class B breakers and had to settle for the class C.
Running only resistive loads I wanted the class B rather than the Class C that is best for surge/inductive loads...anyways, the fuse will break the curcuit before the MCB kicks in and decided to integrate the MCB's as a manual switch with the added benefit of having a circuit breaker in the mix.
Apologies for delay in reply, had a bushfire keeping us on edge for well over a week.
Choppers dumping water used our house as a flight path to the fires, sirens going off as they past overhead every 20 minutes whenever the ground crew called them up..
