Set up your solar panels in two strings of 500 watts each in a 5s2p configuration, that's 64 volts (12.8x5), and two 40amp Mppt controllers in parallel. If you calculate your amperage, you now have 7.8 amps instead of 83. You can run that with a suitable 20 amp extension cord. The MPPTs will...

Good questions, all, and I'm interested in the answers because I plan to have my Victron charging off my 2nd alternator while driving with the solar panels on the roof charging via the MPPT controllers simultaneously during the day if I use the overhead 15,000 BTU A\C. Everyone I've queried so...

I'm old, retired, and on a budget; buy what you can afford that works for you; there's no shame in that. Ingenuity is cobbling together something cool out of bits and pieces on a limited budget and being satisfied with the results. :cool:

I thought this might interest some; Perovskite solar cells might revolutionize collecting our energy from our power plant in the sky. Now, of course, nobody has any idea as yet when they will be commercially available, but I'm going to guess that we're going to be hearing more about them within...

You can't fight human nature, and when you try, it fails because it is what it is; live with it or go crazy.

Good one!

A fury tree rodent with a cute fluffy tail, and no matter how hard one tries to keep them out of his (or hers) bird feeder, they always win.

Never apologize; it defeats one's sincerity. If someone gets upset, it is what it is.

I bought Chins 12-volt 200ah batteries for $600 each, and the 100ah batteries were $315 on Amazon. We have a Chins rep running a thread on the forums; here's the link: https://diysolarforum.com/threads/chins-battery-introduction.26787/ Will, who created this board, did a teardown of the 100ah...

I'd re-phrase your question in the BMS Forum Section:

Do the 2p8s and get a 200 amp BMS. This way, all you need is one BMS. What are you trying to power with a 6kW inverter? You're going to need a lot more battery. I have 24.8v @ 400ah and have a Giandel 24.8v 4kW inverter; divide that out, and you get 162 amps wide open.

LoL, good answer, short and to the point. :cool:

Good answers. A tip from an old engineer, a rule of thumb is 1.7 hp per 1kW of power when sizing generators to a specific load. Therefore a one hp pump requires approximately .7 kW to operate.

It's doable, but not sure the ends justify the means. Your belt runs the alt, h2o pump, and power steering pump. You can run an electric h2o pump, but that's an issue unless you want to do away with power steering. A good way to test your actual load on the battery is to hook up a shunt on the...

Why?
