WOW - a lot of info to wade through! Thanks everyone, for your time, interest, and knowledge!

Just to reiterate - everything in the system is new. The battery has never been drained below about 11V, because the inverter (which IS a "pure sine wave inverter) will indeed alarm right around there. The generator doesn't seem to very effective at charging the battery when it is so close to fully charged, which makes sense? Almost like there's a certain amount of "electrical pressure" like a balloon gets harder to fill the more you fill it...

And yes, I fully get that it's a wasteful way to charge a battery, but the alternative is lugging that beast back and forth to house power, until I set up a solar array. Until then, I'll burn some dinosaur bones in the interest of ironing out some kinks like this....


Thanks again,

Joe

Thanks, guys! Yes, Eric, I do have a volt meter - I'll pull it out and get you some more numbers...

I think you may have hit the nail on the head about the rope lights, though - although they are nearly brand new, there is about a 4' section that does not light.... oddly enough, there is about 6' of lights beyond these dark bulbs that do light, so juice is getting to them somehow.... could it still possibly be a "short" where they're dark? The ones that are lit beyond the dark bulbs do not appear to be any more dim than the bulbs preceding the "short" - maybe I'll just return them and see if a properly functioning one exhibits the same symptoms...

John, yes, I know the kill-a-watt you're talking about - don't have one, but have frequently thought it would be handy to have. Though, as I said, I do have a pretty good volt meter, so maybe I could garner the same info from that? Not sure, as I said, my electrical knowledge is pretty rudimentary...

Thanks, Eric! Again, the battery is only being drained from 12.5V down to about 11.5V, but that's enough to freak out the inverter for some reason....

Here's the link to the generator, too...

Not trying to send you down a rabbit hole that is not of your making, my friend! Don't spend any more of your valuable time on it than you like, ok?

Thanks, Eric! That's what I thought, without doing any math... I'll give you the link to the inverter - maybe there's something that will jump out at you there... think its 1000W...

I've charged rechargeable AA batteries, my phone, my bluetooth speakers, etc from the battery via the inverter - does not seem to trigger it so quickly. Again, it's not that the battery is dying, it just seems to be getting drawn down to a level that the inverter "deems" insufficient? Is that possible?

Hi, everyone! Thanks for letting me pick your collective Brain!

I recently purchased a deep cycle battery, a pure sine wave inverter, and a battery re-conditioner/trickle charger. I intend to build a small solar array in the spring. In the mean time, I am experimenting with charging the battery with my 1250 watt generator => trickle charger => battery. I know that this is a terribly inefficient way to go about things, but it's just a temporary way to begin the learning process about battery power and a way to avoid having to transport the battery back and forth to charge it from house power, so please forgive the transgression!

In any case, all that I typically power with the battery is a 50' run of LED rope lights out at my yurt. They are 110V plug-in type lights, plugged right into the outlet on the inverter. I believe the draw is pretty low (approx 33W) but even once the battery is fully charged to 12.5 or 13V, I can not run the lights very long (approx 45 minutes) before the inverter begins to alarm, indicating that the voltage of the battery has dropped below some critical threshold. (I think at that point the battery is down to about 11 - 11.5V).

Does this make sense to anyone with more than my very rudimentary electrical understanding (i.e. me)? I had hoped that the lights would just keep running until the battery was fully drained... what gives?

Looking forward to where this leads,

Joe
