Hi I would like to install an 8kw inverter with a battery in parallel with a 3kw inverter with a battery and about 1kw of solar I have 3kw solar installed on a 3kw inverter already. I was hoping to use an export limiter grid side. Dose anyone see any problems with this. I have been told it's not possible and that I will have voltage issues and not be able to charge the battery off the grid at anymore than 3kw/h this sounds nonsensical but mabie I'm missing something.
