Configure your Ultimati home battery

Ten questions, an instant indicative proposal for Ultimati Energie Standard: low-voltage RE-LA1 for single-phase or high-voltage RE-HA1 for three-phase. LV and HV can never be mixed.

Configure your Ultimati home battery

1. Annual electricity use (kWh)
2. Annual solar export / surplus (kWh)
3. Do you have or plan a heat pump?
4. Do you charge an electric car at home?
5. Do you have a dynamic energy contract?
6. How much do you want to draw from the battery in the evening and at night?
7. Grid connection
8. Where will the battery go?
9. Backup power wanted?
10. Do you want to expand later?

  • Indicative and not binding; based on your answers, not on a measurement.
  • HV modules only work with the HV inverter; not combinable with LV.

Still to be confirmed: Order code UE-12K-T2-HPB1 vs datasheet code -T2-HA1 to be confirmed with Ultimati Energie.

Required components & technical review

Confirm UE-12K-T2-HPB1 versus datasheet -T2-HA1 before combining with HV modules; no LV modules. The bill of materials must include meter, base, connections and protection. Selected-circuit backup depends on exact type and design; Standard warranty is not Premium warranty.

Quote only. The final bill of materials and compatibility are not yet approved.
