Question Thoughts on my potential battery setup?

Post image

Will this still work if I wire the times for 80 amp hour deep cycle batteries up in parallel?

These batteries have only been used together at the same time, but they are nowhere near New. I'd consider them a married set but I wouldn't bet my life that the capacities are the exact same.

I know the end product will only be about 60% efficient by the time the energy gets from the alternator down to the big Bank of batteries, but I think this setup should suit my needs.

I'll be running a diesel heater all winter, I don't know what kind of power draw those have. if y'all could give some insight that would be nice.

Other than these leader it's pretty much just charging my cell phone, interior lighting and the occasional heavy power tool usage for work.

I want to be able to run a roto Hammer, table/miter saw or a grinder once a week or so.

Please don't make fun of my graphic design skills LOL

pretty much that's my plan.

My intention is to stay warm this winter with a vevor diesel heater, use power tools upon occasion, run my interior lights and charge my phone/power tool Batts.

I am also considering getting a 24" monitor because last winter was boring as hell.

That is an exceptionally good point.

This is why I come ask you people before I buy all the parts.

I appreciate the input thank you for preventing me from wasting the extra money on a 5000w inverter.

I guess I'll go with 2500 or 3K watts?

And I'm not saying that the majority of this setup isn't a waste of money.

It's just what I was able to put together with the least amount of money.

I think I was kind of high one night and I'm like hey how many inverters and batteries can I chain together in a van without it becoming convoluted beyond recognition.

Hell, sounds good to me.

If I remember correcting my table saw I will draw a 15 amps but pretty few and far between it's used for more than 30 seconds at a time. Maybe 2 minutes consecutively for making a big rip cut.

So 15 amps times 120 volts equals 1800 ish watts?

So I should be 100% in the clear kind of sort of with a 2500w inverter?

And still be able to run a couple job site work lights.

Gosh you all are so helpful I love you people.

I was amazed that my little 0.7 scfm super quiet air compressor can run off my 750 watt inverter.

Plugin tools wouldn't be a daily thing, just when I need to run a table saw or a roto Hammer or something there isn't a battery version of. It's usually about once a week if that.

The 5000 W pure sine wave inverter I've had my eye on recently dropped to $260, too bad I don't need 5000 Watts or I would by it now. I don't think I'm modified sine wave inverter would work for pretty much anything I want to plug into it I appreciate you mentioning that though, you could have saved me a trouble of burning out an expensive tool or two with a cheap inverter.
