Need some advice. Sorry if this is a basic question. We have bought a property that has 20 -375w Panels. 2 x Solax X1-Hybrid 7.5KW Inverters. 2 x Lithium Batteries . Basically 2 individual systems. The system has never been set up. Can the 2 x Inverters be connected at the same consumer unit for self use. I only have 1 x single phase supply incoming from Grid.
