Description
Fox ESS H3 PLUS 125kW 3‑Phase Hybrid Inverter
Key benefits
- 125kW three‑phase hybrid inverter for large commercial and industrial sites combining high‑voltage LFP batteries with substantial PV capacity.
- Designed for long backup capability, fast EPS switchover and 100% unbalanced three‑phase output to support critical loads on complex three‑phase supplies.
- Integrated with FoxCloud V2.0 for advanced remote monitoring and system management across multi‑inverter and multi‑battery installations.
Brief description
The Fox ESS H3 PLUS 125kW Commercial 3‑Phase Hybrid Inverter sits at the top of the H3 Plus range, which spans from 50kW to 125kW for commercial applications. It supports high‑voltage LFP battery stacks, long backup runtimes and less than 10ms EPS switching, making it suitable for logistics hubs, production lines, data rooms and other sites where continuity of supply matters. With a wide DC voltage window, high efficiency and IP65 construction, it is well suited to indoor plant rooms or sheltered outdoor installations.
Key features
- Three‑phase hybrid inverter with 125kW nominal AC power and up to 137.5kVA AC output on the H3‑125‑Plus model.
- High‑voltage LFP battery support (180–950V) with up to 240A charge/discharge across three battery ports (80A + 80A + 80A).
- PV input up to 250kW with 8 MPPTs and two strings per tracker for flexible commercial array design.
- EPS function with less than 10ms switching time, 155kVA EPS rating and 300A LRA for starting demanding loads.
- Colour LCD display plus LED/Wi‑Fi app interface via FoxCloud V2.0 for local and remote visibility.
