Well Battery Question

I think I get it.....

You want to recharge your batteries through the mains or gennie powered smart charger while the inverter is connected to the batteries?

If that's it, the answer is yes, but with reservations.

Best, Peter

Thanks Peter.Battery Value
Your First question you sent to me re Charging Cabin Batteries by inverter connected to same batteries , if this is possible Both inverter & smart Charger are fixed in Truck
But you stated with reservations.Please advise on what problems I will have and are I asking for some think I don't need.

I only use the smart charger to charge batteries when home to house hold Power,The Generator via smart charger if batteries are getting low when camped for some time & the solar panels can"t keep up to my power supply no sun only rain

I have a isolation switch between my starter- and cabin batteries, and also a solar regulator between solar panels and cabin batteries. with Gauges to show charge rate to batteries,& gauge to monitor Batteries 12.5 approx
I am looking for information to improve my system if possible

I wish to charge Cabin batteries with the Inverter is running of cabin batteries when camping .l thought this would drain my cabin batteries not build the power up
When driving all 6 batteries are all been charged by Truck alternator.
Should I connect Solar Panel Permit as I only connect when parked

Crackles summed it up pretty well below....

No you definitely can't charge your cabin batteries via inverter connected to them and smart charger plugged into the inverter. If you tried doing this, your batteries will get discharged, as you already assumed correctly.

The 'with reservations' is for mains/generator powered charging the cabin batteries while the inverter draws power from them. Yes, that's possible but your charger might get confused by the inverter current.

Best regards, Peter

Thanks Crackles.& Peter.
I myself thought this was true what you both advised,as I use the Inverter only in a urgent situation as I can see the batteries drop fast in power when The Inverter is on
So as most would say what works good leave will alone.
