I have a multiplus 48/3000/35-50 inverter with a battery pack acting as redundant power for a server room. I have a problem where when the site is running on generator power, the inverter is apparently feeding power back into the grid (the "grid" wattage goes negative)
When this happens, the inverter throws overload warnings and will sometimes throw an alarm and disconnect my loads. (production servers) Once this happens, the power on the inverter needs to be cycled.
The load is relatively small at this point (300W) but the grid/genset is very large (100s of kW)
How do I configure the inverter to not transfer power back into the grid under any circumstances?
