Hi, I am looking for some guidance, I have an ESS system, with Fronius primo on input, with a Multiplus in grid parallel ESS with Pylontech / RS 450-100, ET 112 meter
In EVCS Auto mode, When the battery is not at 100% the system charges the car at the full power of both inverters, which is great, but when the battery gets to 100% the EVCS ramps down to only use the Fronius, the RS solar then goes into idle along with the Multiplus, so my car only charges at half power after battery hits 100%, If i set it to manual at a high charge rate the Multiplus will kick in with the RS solar also ramping up, Why in auto mode will the EVCS not utilize the power of the Multiplus and excess solar when the battery reaches a full state? Is there a setting somewhere I have overlooked?
Kind regards
Stew
