The differences that matter
- Phases → three-phase against single-phase: it depends on the home's electrical supply.
- Backup → none against a UPS with a 10 ms transfer: in an outage only Zendure steps in.
- Power → 7 kW against 3.68 kW continuous and 7 kW against 4 kW charging (manufacturer-declared values).
- Environment → IP30 and −5 to 45 °C against IP65 and −20 to 55 °C; 165 kg against 80 kg.
Which one to choose
Choose sonnenBatterie 10 performance if…
the house is three-phase and needs power: 7 kW continuous and charging, 10 kWh usable expandable to 50 kWh, with wallbox communication and the sonnenVPP virtual power plant. The trade-off: no backup power, 165 kg, IP30 and −5 to 45 °C.
Choose Zendure SolarFlow 4000 Mix Pro if…
the house is single-phase and needs continuity: UPS with a 10 ms transfer, grid charging with time-of-use tariffs, IP65 and operation from −20 to 55 °C, 80 kg. The trade-off: 3.68 kW continuous and 4 kW charging, single-phase only.
