Hello,
I have been running an ESS consisting of the following components for about 3 months:
- EM24
- 3xMultiplus 5000
- 1x Fronius Symo 10.0 (connected to ACout)
- 45kWh battery
Everything was working fine until our network operator carried out maintenance work today and as a result the frequency in the local network was increased to 51 Hz. (at AC IN)
The Multiplus 5000 immediately began charging the battery from the mains. Although several consumers in the house should actually draw their energy from the battery, the entire house was supplied from the local network.
Is there a configuration error in the ESS?
Thank you
Best regards
