Additionally, the proposed charging algorithm ensures that the energy storage system imports energy from the grid during off-peak hours and maximises power generation from the DC subgrid. The efficacy of the proposed strategy is validated using a modified IEEE-33 bus system as a test case for a hybrid AC/DC microgrid.

So having a problem, load shedding starts all is well, however as soon as the inverter reconnects to the grid the earth leakage trips, assume its transient earth leakages or something (P.S. not load shedding related as if you kill the mains and reconnect, it does the same) I have nailed it down the the alarm system AC transformer

Update: Checked the OSG in section 7.2.5 and as far as understand it, as long as the cables are not "installed in walls or partitions", which surface mounted trunking isn''t, there is no requirement for RCD protection. The prospective fault current in a fault condition inside the Multiplus would easily cause disconnection of the 50A MCB

If the upstream one responds first, the AC input to the inverter will be disconnected, but then the inverter will run and the NE relay will need to close also, afterwhich the downstram RCD or RCBO will respond. This delay may exceed the allowable time for an RCD to disconnect. In addition there is the disruption to upstream circuits.
