I'm trying to find information on any 12V battery charger(for flooded lead acid) that will work with modified sine output from a generator. Want to purchase one but every charger these days have some sort of printed circuitry that may not work with a generator. Anybody have any knowledge / experience with this. Would appreciate any advice on name brands or models that would work.

Well the throne thing you need to work that out on your own
Now running off a generator keep in mind that frequency is constantly changing with variations of load. This is worse on smaller generators than very large ones but frequency will change.NABCEP certified Technical Sales Professional

A power generator is a combined unit of a engine and alternator.
A inverter produces AC power from DC & batteries.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

Sorry, I'm going to step aside on this thread, there is something I'm just not getting.

How about we start with make and model of the generator that is burning up the appliances.NABCEP certified Technical Sales Professional

To summarize what I take from it for this application:
1. Modified Sine Wave generators: Mostly if not exclusively older inverter type generators. If the OP has one of those, it could cause problems with electronic loads.
2. And if he has a generator which has a limited current output and poorly designed regulation, the peak output voltage may be stabilized, but the waveform can change in a way that increases the RMS voltage. That could overload heating appliances like a toaster very badly.
If the OP uses a meter which just measures the peak AC voltage and multiplies by a constant to read RMS, he would not see that the generator output was actually going too high.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

Have you checked the voltage on the generator?
Forget the exact problem, but an old one I had was putting out too high a voltage I think - and that lead to things catching light etc.
It was then stolen after I'd left it out (normally quiet street) - hopefully they used it first and burnt some of their stuff out .Comment
