- Estimated round-trip efficiency (charging + discharging): 87.1%
- RTE measured by MyGrid: 86% with 800 W charging and discharging; 87.1% with 1,200 W charging and 800 W discharging. Actual efficiency depends on power level and conditions.
- Effective cycles per year: 330
- Solar electricity used directly without a battery: 30%
- Discharge power 800 W for at most 8 hours per day
- Shiftable share of your daily consumption: 45%
- Range around the estimate: ±20%

Indicative. RTE measured by MyGrid: 86% with 800 W charging and discharging; 87.1% with 1,200 W charging and 800 W discharging., depending on power level and conditions. These figures stay cautious, assuming 87.1% of the capacity reaches your appliances. ModuleTwo delivers up to 800 W at a time through a regular socket, so with a heat pump or dishwasher it covers part of the consumption; the rest comes from your panels or the grid as usual.
