I am attempting to add the 100A autotransformer to my Sol-rk 12k setup for balancing the load (single-phase 240v). My setup most closely resembles 2.3.1 "Balancing a Generator or Stacked Inverters" in the manual except that my inverter supplies the load from the grid when sun's down and batteries are empty.
What's the recommended way to maintain that grounded neutral path back to my main panel at the service entrance since I'm creating a new Neutral at the AT? The manual isn't clear on how to utilize the ground relay with non-Victron inverters.
