If your battery charger is available it implies that mains power is available so the inverter would not be needed???

Charging & running an inverter is what an expensive UPS (uninterruptible power supply) does.

But these Double Conversation UPSs (Eaton for example) are very top end for powering even more expensive equipment.

The only situation to charge & use your battery simultaneously would be if you have a heavy load which can be reduced with solar input.

But if you have 230v, use that.

Not necessarily. The charger might be using solar panels as a supply source.

No need to turn your charger off when using anything from your batteries, provided your batteries are in a reasonably charged condition to handle the load applied to them.

I suspect the inverter will be powering the whole van.

The the battery charger if plugged into van power would be just wasting power trying to replace what the inverter is using.

Maybe it's a 240V>12V charger.

Maybe it's a solar>battery charger.

Maybe it's a 12Vdc>12Vdc charger.

Who knows? confuse confuse confuse

I probably should have supplied more information :I have a BM Pro management system. and while using the inverter the battery is indeed being charged while neither on mains or solar.

While confessing to a high degree of technical ignorance what I think occurs is a loop - inverter>charger>battery>inverter .

What charger?

Inverter details?

Is it a 240V>12V charger plugged into the inverter and connected to the batteries?

Is the solar charger switched off only when the inverter is used, and if so, why?

Your original post refers to a charger and an inverter. confuse

I use invertor when charging by solar or from vehicle when driving. The charger auto swaps from vehicle charge to solar when I stop. I run invertor when driving as prefer to run the Engel off 240v with a proper 240v plug. I Don't trust the cig lighter connections.

Replace the sig lighter connectors with Anderson plugs and upgrade the cable too.
I believe that the car fridgesl rectifiy the 230Vac to 12Vdc and that the fridge compressor is powered by 12Vdc.
Else it would have two compressors.

Probably best to follow jegog's recommendation. Most efficient way.

Interesting that your solar is producing AC or for that matter the typical vehicle.

It's worth investing for a World Patent with your discovery, you need very deep pockets for such patent.

P.S. I will not be investing.
