Deye GE-F256-BC-2-A3257.23kWh 819.2V outdoor battery cabinet for commercial sites

Overview

The outdoor battery cabinet of the ORION E series: 257.23kWh in a single IP55 enclosure, sixteen 314Ah BOS-B-Pack16-A3 modules in series at 819.2V, a built-in air conditioner that keeps the temperature difference between cells within 6°C and an aerosol fire suppression system with a water inlet. There is no inverter inside: it pairs with Deye 60–125kW hybrid inverters or with the SUN-125K-PCS01HP3 PCS, and the accessory kit changes accordingly. Up to ten cabinets run in parallel, about 2.57MWh. Made to order, delivery 3–4 months; transport is quoted for the delivery address.

• 176.84, 208.99, 241.15 or 257.23kWh in one outdoor cabinet
• 16.08kWh, 314Ah modules, 11 to 16 in series
• IP55, operation from -30 to 55°C
• Air conditioner, aerosol and water fire interface
• Inverter brackets on the cabinet wall
• ≥8000 cycles, 10-year warranty

How it works

The GE-F240 series, part of Deye's ORION E range, is an outdoor battery cabinet that houses BOS-B-Pack16-A3 modules (314Ah, 51.2V, 16.08kWh), a BOS-B-PDU-2-A distribution unit with BMS, an air conditioner and a fire suppression system. GE-F176-BC-2-A3 holds 11 modules at 563.2V, GE-F208-BC-2-A3 13 modules at 665.6V and GE-F240-BC-2-A3 15 modules at 768V, for 176.84 to 241.15kWh.

Recommended current is 157A and maximum continuous current 180A, with 285A discharge peaks for 15 seconds between 20 and 45°C; rated DC power is 88, 104 or 121kW. The cabinet pairs with a Deye hybrid inverter mounted on its side wall, which links PV, grid, loads, generator and battery, so a single cabinet can form a PV plus storage or PV, storage and diesel system.

Safety and thermal management

Deye describes six layers of protection: electrical isolation, fire detection, active exhaust, explosion venting, fire suppression and thermal isolation. Inside are smoke, heat and CO detectors, an aerosol unit triggered electrically or by flame, two explosion venting panels and a DN40 inlet for a customer-provided water supply, with a manual master valve at least 3m from the cabinet. The air conditioner keeps cell temperature spread within 6°C, without derating up to 45°C.

Installation and compatibility

The cabinet stands on a concrete foundation at least 300mm above the surrounding ground, levelled to 3mm, extended 100mm beyond the cabinet and with cable trenches for bottom entry. For several cabinets the manual sets clearances of 100mm and 1500mm, as drawn in its layout. Sites must be more than 2km from the coast and at set distances from pollution sources; corrosion protection is C4-M as standard, up to C5 on request.

Two accessory kits cover the inverter connection: GE-F256-AP-A for SUN-125K-SG02HP3-EU-GM10, SUN-80K-SG02HP3-EU-EM6, SUN-50K-SG01HP3-EU-BM4 and SUN-50K-SG02HP3-EU-BM4, and GE-F256-AP-C for the SUN-125K-PCS01HP3 with MPPT and STS modules. Deye allows up to 10 cabinet systems in parallel on the AC side or 10 on the DC battery side. The PDU needs a 200–240V, 3A auxiliary supply for its fans.

Monitoring and settings

A coloured Deye logo on the door shows standby or discharge, charge, alarm and fault, and the PDU display shows state of charge and fault codes. The battery reports to the inverter over CAN 2.0 or Modbus RS485, and the system can be monitored and controlled in Deye Cloud through the inverter, the web portal or Bluetooth on site. An emergency power-off button and a manual service disconnect allow safe isolation for maintenance.
