Frequently asked questions

We have put together some commonly asked questions

  • During GENSET Prime, in case the SoC exceeds the configured threshold, the controller launches the automatic transition to BESS Prime.
  • (only for ePowerControl MC) During BESS prime, in case the SoC drops below the configured minimum threshold, the controller launches the automatic transition to GENSET Prime.
The controller manages the Start/stop of the genset in grid following mode on load condition to provide support to the BESS. The genset’s active power output will be controlled to keep the active power of the BESS below a configurable maximum power.
To ensure the maximum exploitation of the PV resource, the controller includes a PV Optimization function, which sends active power setpoints to the BESS, running generators and PV inverters.
