Fox ESS · single-phase hybrid inverter
Fox ESS H1 & AC1 (G2) hybrid inverter, 3–6 kW
Two machines on one platform. H1 is a full hybrid: it works with the PV array and the battery at the same time. AC1 is a storage inverter with no PV input — it connects to an existing grid-tied system and adds a battery and backup power to it.
H1 or AC1 — the difference
H1 goes on a new system: it has a PV input. AC1 is for retrofits — the panels already run through a grid-tied inverter and AC1 simply adds a battery to the system.
Storage grows with the site
Up to seven high-voltage batteries in series — 33.24 kWh in total. Start with one and add more as needed.
Backup power
The EPS output picks the house up when the grid fails: switchover under 20 ms, so equipment does not reboot.
High-voltage battery
Running at high voltage gives better charge and discharge efficiency than low-voltage systems: 98.5% and 97.0% respectively.
