In two weeks we will be heading to the mountains where there is no power. We have an inverter generator we will use as needed. However, we are restricted to 10pm with running the generator. I have put together the following system to provide power to our tv, dvd, dvr. Two 6v gulf cart batteries connected in series, one 200amp fuse, one 2000watt psw inverter and all cables. My plan is to attach my smart charger to the batteries and charge the batteries each morning as we prepare coffee and normally run the generator for a few hours each day. I'll be turning the inverter off each night. Well there be any issues with leaving the inverter hooked up to the batteries during the charging cycle. Any input or advise would be welcome.

At one time most all convertors were not very good. That is not necessairly the rule nowadays. Some are very good smart type chargers.
What does your unit have?

There is no problem leaving the inverter on the batteries while you are charging the batteries. Everybody does that, as most inverters are "installed" so you can't disconnect them anyway.

Obviously, it is better to not have any draw on the batteries while you are trying to charge them as that slows down the time it takes (because your net amps in is less) and you want short as possible generator time.

Note you went from a 2000w inverter in the OP to a 1000w later. ???

The so-called standby draw of an inverter is fairly trivial in the scenario you describe. If you don't have a remote to inside the rig for the inverter, then if it means going out in the dark and rain to shut it off at night or to turn it on in the morning, then just leave it on ๐Ÿ™‚

pianotuna, The system I have put together is separate from my trailer. My plan is to recharge my 6v batteries from a portable smart charger that is plugged into my inverter generator. My biggest concern is leaving my xantrex 1000 psw inverter connected to the batteries while charging the batteries with the portable smart charger and am I missing anything on my set up.

Hi Robert,

Welcome to the forums.

Leaving the inverter on may lower the charge rate by what ever the parasitic draw for it. That varies from one inverter to another--but it can be as high as 3 amps.

This also depends on the converter and how it recharges the battery bank.

What make and model of converter is in the RV?

Be aware that the generator may not output full power at high altitudes.
Regards, Don
