A Multiplus II shows negative AC output wattage in a Parallel Split
While I was troubleshooting the negative AC thing I found that when it is in inverting mode, it indicates L1 and L2 out of phase. When the grid is turned on, it accepts the
AC output negative when grid connected
When I have a 4000W load connected and switch no grid, the ac-out drops to 2000W but same amps. My supplier think its a mearing or shunt issue. If the second unit was
Positive and negative VARs and Solar inverter Grid connect
Assuming my understanding of the above is correct, adding negative VARs (adding capacitance) would usually have the effect of raising voltage levels due to most grids

What does the negative value for load mean in the System Status
If the load shows a negative symbol, then that means that the unit is in AC coupled mode. AC coupled is selling power to the grid from the AC output of the inverter.
A Current Control Method for Grid-Connected Inverters
In this paper, we design a voltage modulated direct power control (VM-DPC) for a three-phase voltage source inverter (VSI) connected to a weak grid, where the PLL system
