Solar battery hiccup

[Plogowoman]

Hello. We own a 2021 Roadtrek that we just love but it has one problem we can’t figure out - The battery level can be at 100% and you run the A/C and microwave or the coffee maker and microwave or any two things at once and it blips to 0% and you have to listen to constant beeping for a couple of hours IF you are in a sunny spot.
Just completed a pricey conversion to BUSS bar system and added another battery for a total of 6 and same thing happens.
Any ideas?
Thank you.

You are expecting to much out of the system .

What size and type are the 6 batteries?

None of the systems you mentioned are powered off my battery bank. Only when on genny or shore power.

Sounds like something between the batteries and the inverter is shutting down due to the large draw or rush of current. What kind of batteries and what is the system installed? And it would have to be a huge inverter regardless of battery power to run the microwave and AC. I agree that you are expecting to much and we will see when you tell us the inverter make and power.
