261 kWh Liquid-Cooled Outdoor Energy Storage System
GYL-261 brings LFP battery storage and a 125 kW bidirectional PCS together in an integrated cabinet for commercial and industrial energy management.
Storage and power conversion, brought together
Store energy, manage site demand and coordinate charge and discharge from one integrated platform. GYL-261 combines battery capacity, bidirectional AC conversion, liquid cooling and connected controls for a compact outdoor installation.
Integrated PCS
The inverter is included in the cabinet architecture, converting power between the battery and the AC system.
Liquid-cooled batteries
Thermal management supports consistent operating conditions across the battery system.
Connected operation
Cloud web and app monitoring support remote visibility, scheduling and operation.
Five functions. One coordinated system.
Battery | Stores energy
LFP cells store electrical energy as DC power.
BMS | Supervises the battery
The battery management system monitors cell conditions and sets operating limits.
PCS | Converts power
The bidirectional inverter converts AC to DC for charging and DC to AC for discharge.
EMS | Plans operation
Energy management selects when to charge or discharge within battery and PCS limits.
Cooling and protection | Maintain conditions
Thermal management and protection systems support operation and respond to abnormal conditions.
Put stored energy to work
Peak demand management
Schedule discharge during demand peaks to help reduce grid draw, subject to the site load profile and tariff.
Renewable energy integration
Coordinate storage with the site's renewable generation and AC distribution design.
Backup and off-grid projects
Off-grid output supports suitable system designs. Transfer arrangements and critical loads determine backup performance.
Designed for visibility and daily operation
Remote monitoring
Monitor the system through cloud web and app interfaces, with local and remote wireless control.
Smarter scheduling
AI-assisted strategy optimisation supports energy scheduling around operating priorities.
Temperature management
Liquid cooling and control algorithms support a system temperature difference of ≤5°C under the specified operating conditions.
Layered safety
Detection, prevention, ventilation and fire suppression form a coordinated safety approach.

From cell handling to system integration

Coordinated cell handling, battery assembly and cabinet integration support a consistent production workflow.
Define the configuration
Align the battery, PCS, cooling and control interfaces with the order specification.
Plan quality checks
Set inspection and functional verification requirements for the assembled system before delivery.


Prepare the cabinet for its next destination
Plan handling and protective packaging around the cabinet dimensions, weight and shipping route. Discuss crate, pallet and destination requirements as part of the order.
Reserved handling interfaces support lifting and installation planning. Site access, foundations and service clearances should be ready before delivery.

Before you select your system
Is the inverter included?
Yes. This integrated design combines 261 kWh of battery capacity with a 125 kW bidirectional PCS.
Does 261 kWh mean two hours at full power?
261 kWh divided by 125 kW is about 2.1 hours before losses. Actual duration depends on usable energy, operating limits and auxiliary consumption.
Is backup transfer seamless?
Off-grid output ratings do not specify transfer time. Select and verify the switching arrangement for the connected loads.
What should I send for a quotation?
Share the load profile, operating objective, grid voltage, site conditions, quantity and destination market.
