Explain AC current limit Multiplus II 8000/48

Hello group, could someone explain to me exactly how AC CURRENT LIMIT works?

I have Multiplus II 8000/48 3 pieces operating in 3 phases. Does setting AC CURRENT LIMIT e.g. 32A mean that the inverter is able to pass through itself 32A in total or is it only the power from the battery and solar panels (MPPT chargers).

I would also like to ask for an explanation of how much power 1 inverter is able to pass through itself:
~6400W battery and MPPT

  • GRID - how much?

I apologize, but I did not find the answer to these questions.

No, its the maximum current the multi’s can draw from the grid…per phase

The Data sheet for the 48/8000/110-100 shows that it’s transfer switch is rated to 100A.
This indicates a peak power from grid limit of ~24kW. This should not be continuous, or switched frequently by the inverter. max continuous power should be about 15kW - 20kW per phase.

Thanks for the answers and sorry if they seem stupid, but I’ve only used GROWATT inverters so far and they weren’t that advanced.

For example:
I’ll set the CURRENT LIMIT AC to 45A (~10kW at 230V) which means that if the power from the battery and solar panels can produce ~6.4kW, then the inverter will be able to handle ~16.4kW per phase?

One more question, can I limit the power that the inverter can draw from the battery to 50A, for example? I currently have two 15kW batteries and I wouldn’t like to load them with more than 100A in total (50A per one)

No, there is no parameter in the system to limit the current used, only for charge current.
