What i want to do create a 2nd fuse panel ran entirely off solar.
For the easy of math i only want to run one window air conditioner, 12000 btu. (This will be scaled up at a latter date)
15 amps at 115 volts= 1720 watts
I would need 6 x 320w solar panels just to run in a 100% efficient world...
What is everyone using for a 48v to 13.8v converter?
The biggest i find is about 60 amps
I have a 5kw rv set up thats not installed yet.
The motorhome has both 12v and a trace engineering 2500w inverter.
I have 2 options
going to 36v or 48v and using a buck converter for everything.
I'm feel like im concerned with what lots of people here seem to be doing.
Tesla has a 85kw pack in there car, It is that large cause it has to be(amp draw).
Now your never going to hear them advertise that.

Its a total pos,
Way to long to heat up
Doesn't get hot enough
Doesn't transfer heat for very long
Its so long and heavy that it almost takes 2 hand to run
It was listed as 220v but has a usa plug on it.
I wonder if it really needs 220v and that is the problem.
Soldering fuse wire to a...
as you already know buying batteries and flash memory on ebay from china, its all fake.
so are the fotek relays, many youtube videos of them being tore down and checked.
40 amp will not work with 40 amps.
if you can afford a fotek relay on ebay its fake, the real ones are EXPENSIVE.
So 2 years ago when I started, this is how I tested my batteries.
I tested all 320 batteries in a weekend.
I wasn't after perfect results,
My solar controller logs everything.
I would be able to tell if I have a strong or weak set in the pack and add or subtract cells to even it out.
So in my search of a cheap power supply.
Constant voltage and current limited.
Find or wind a transformer from 110v to 16v

Looks like they just stacked the chips in parallel.
