Our verdict

The high-voltage battery architecture is the distinguishing feature: an 80–480V battery port rather than the 48V-class port on the GivEnergy, Growatt and Sunsynk hybrids, which raises round-trip efficiency but is specified for Fox's own high-voltage battery range. Output is 5,000W rated at 22.7A per phase, so G99. Maximum efficiency is 97.08%, lower than the other 5kW hybrids added alongside it, and the EPS output can hold 6,000VA for 60 seconds. IP65 and 22kg.

Good
