WG6.22 of CIGRE defines microgrids as "electricity distribution systems containing loads and distributed energy resources (such as distributed generators, storage devices, or controllable loads), that can be operated in a controlled, coordinated way either while connected to the main power network or while isolated." A microgrid can offer a
Now wrap your head around this: If you connect a PV inverter so that extra power is being fed into the grid BEFORE this sensing point, then instead of attempting to zero this point by taking power from the battery, the Multi will not attempt to zero it by putting the power INTO the battery. It works in both directions.
A reverse power relay prevents a solar system from backfeeding the grid, or limits backfeed, or similar functions. I''ve never had to install a reverse power relay, but I''ve heard they cost many thousands of dollars.
