Hello, I would like to ask if you can use powerassist with inverter as primary source in overload condition. I am asking this to determine if 1x inverter will be sufficient or whether it would have to paralled 2x to accomodate rare cases or overload (electric cookers 4kW + random loads under 3kW). Let me explain:
Inverter: Multiplus-II 5000VA
Grid: Available and connected, limitless
Battery: Ideal and limitless
Normal conditions: Loads under 5000VA operate on invertor without issues (>95% time)
Question condition: Loads exceed 5000VA - Invertor overload (not counting on 130% overload possibility @ 5minutes)
When loads exceeds rating of invertor I would like it to feed in the rest from the grid (if available) resulting in 5000VA from invertor and rest taken from grid - stable over 5000VA system for limited time period. Meaning the priority should be always on batteries and invertor power and grid only used if required. I understand that if grid fails at that moment, the system would shutdown due to overload.
It this possible?
What are the limits? (Total combined power, Switching times, Minimum difference in power consumed vs power assisted, etc.)
I couldnt find answers anywhere in data sheets and powerassist manuals.
Thanks
