FOX ESS - Battery G-MAX 215 kWh - EMU Version

A turnkey BESS solution for your C&I projects
The G-MAX EMU incorporates a LiFePO4 battery, power converter (PCS), BMS, protections and supervision in a single factory pre-assembled container — plug and play on site.

• System capacity : 215 kWh (3.2 V/280 Ah LFP packs) — nominal power 100 kW, peak 110 kW

• Raccordement : triphasé 380/400 V, courant AC max. 167 A, cos φ réglable de -1 à 1, THDi < 3 %

• Performance : round-trip efficiency > 89%, discharge depth 0-100%, ≥ 8,000 cycles at 70% EOL

• Environmental specifications : liquid cooling, IP55 (cabinet) / IP67 (battery pack), -25 to 55 °C, aerosol fire protection

• EMU control : control is ensured directly via the converter's on-board management unit (PCS), unlike an external EMS architecture — a configuration point to be validated with the manufacturer according to the system service targeted (see note below)

• Scalability : up to 10 units in parallel, i.e., a cumulative 2.15 MWh

Professional application areas
With a nominal power of 100 kW and a weight close to 2.5 tonnes, the G-MAX EMU is aimed exclusively at the commercial, industrial and service sectors — residential is not a relevant use case for this format ( FOX ESS offers the EP6/EP12/CQ7 ranges for this purpose).

• Industry & logistics : peak demand shaving, reduction of contracted power at energy-intensive sites

• Tertiary sector & public establishments : large-scale collective or individual self-consumption, securing critical power supply

• PV developers and operators : coupling with power plants Ground solar carports or solar parks requiring downstream storage; monetization of system services (frequency regulation, demand response)

The added value of POwR Connect
The G-MAX EMU is part of the new partnership FOX ESS at the house of POwR Connect Alongside the R110-G2 and R125-G2 inverter ranges, we, as a distributor dedicated to photovoltaic professionals, offer the technical datasheet, installation guide, manual, and manufacturer's warranty conditions (10 years) directly for download on the product page. We also provide technical support for sizing your C&I storage project. Creating a professional account grants access to volume discounts, stock availability, and dedicated support—eliminating the need to manage multiple contacts between the manufacturer and system integrator.

FAQ
What is the difference between the G-MAX EMU and the standard G-MAX? The EMU version controls the system directly via the converter's integrated power management unit (PCS), while the standard version relies on an external EMS module. The choice depends on the intended system service (self-consumption, load shedding, frequency regulation) — to be confirmed with your technical contact POwR Connect according to the project specifications.

Is the G-MAX 215 kWh EMU suitable for residential installation? No. With a nominal power of 100 kW and a containerized format weighing nearly 2.5 tonnes, the G-MAX EMU is exclusively designed for commercial, industrial, and service sector projects. For residential storage FOX ESS , POwR Connect offers the EP6, EP12 or CQ7 ranges.

Can the storage capacity be increased after installation? Yes. The G-MAX EMU is designed for parallel operation: up to 10 units can be combined, bringing the total capacity to 2.15 MWh, without taking over the existing installation.

What certifications and safety standards does the system cover? The G-MAX meets IEC 62619 (stationary battery safety), IEC 62477-1 (power converters), UN 38.3 (transport of lithium batteries) and UL 9540A (thermal propagation) standards, as well as European network codes (EN 50549) applicable to three-phase low voltage connection.
