How long will a 10 KW generatoer run on a good new battery??

Personally.. I think the generac people are FOS... sounds like salesmans speak to me.. typical non engineers trying to give advice on stuff they know nothing about.

electrons are electrons.

if you have a low noise, regualted supply that is at proper battery charge voltage.. it will be NO DIFFERENT than the line their ATS would be sending back to charge the battery.

can't have the cake and eat it too.. so that proves the generac people are FOS and don't know what they are talking about.

( conversely.. that means they may just want to sell you THEIR charge kit.. )

Mind you i would not use a 'dumb' battery charger.. or an un regulated float that had other functions... battery voltage can go too high in some cases... that's why a regulated and emi/rfi filtered supply will be fine...

I have several Battery Tender Jr.'s that I use on Big Reds etc. that puts 800 miliamps. I don't think that would be enough to keep things going when the unit is running.
I also have a CTEK smart charger that puts 3.8 amps on the battery. Do you think that could stay up with the engine requirements when running?
Thanks

Good point about disconnecting the battery. Will do.
Many thanks.

Pulled the ground cable from the battery, and the engine stopped immediately. It is running off battery power.

I just don't see the point of a generator that doesn't run without a battery, or that doesn't recharge its battery, if one is required. Isn't one main point of a generator that I can just keep pouring more fuel in and keep it running?

What I would suggest, if you don't want to hook the battery up to a charger, is to buy a second battery and have it hooked up to a charger while the generator is running. When the first battery goes dead, shut down the generator and swap the batteries.

Solution: Sell the Generac and buy a real generator.

I would wonder if there wasn't something wrong with the generator. I've just never heard of a generator that didn't charge its own battery. If that's the case I'd get adifferent generator.

Good luck.

are you guys not reading any of the posts... at all..

it's been said MULTIPLE times why it won't charge. it is relying upon a line back from the ATS for the charge.. it must have a charge module in the ATS that rectifies some of the gen heads output and sends back as charge/run current for the battery.

that's probably their way to save 10 cents vs putting a dunamo on her or having a starter/generator setup, or a magneto.. etc... i think i might have gone a different way with a charge tap off the head.. or something more similar to the dynamo on a rider mower that doesn't use a start/run setup.. etc.. but that's me. the solid state charge off the ac output can be handled EASILLY in a similar fashion that the generac people are doing it.. but without the sales strong arm tactics..

I am reading the posts, and I understand this. I just think it's dumb. If the ATS is an optional component, then the charging circuit should not run through the ATS. If the ATS is non-optional, then it's back on the OP for not having one. But that doesn't sound like that's the case.

IMHO.. it's a cost saving measure implemented in a poor way. I believe they should sell as 2 options.. ie.. generator with ats, with charge controlled by ats.. with no ats, then there should be an external plug in module.. or a dynamo onthe engine belted up..... etc..

Why not just put a magneto in?
