Inside the cabinet
Scroll to open the cabinet and see what’s inside.
01 · Enclosure
Liquid Cooled BESS for C&I.
Battery, power conversion, energy management, cooling and protection are integrated in a single high-density C&I enclosure.
02 · Battery
LiFePO4 modules at the core.
LFP chemistry is engineered for energy density, long cycle life and operational safety.
03 · Control
BMS, PCS and EMS working as one.
Cell-level monitoring, bidirectional power conversion and smart scheduling coordinate when to charge and when to dispatch.
04 · Protection
Cooling and safety, built in.
Temperature management and multi-layer electrical protection keep the system stable and safe.
What is BESS
Scroll through a day at a site with Durasol storage — from the first sunlight to the middle of the night.
Time
06:00
Battery
20%
Day · 06:00 – 15:00
Store the sun.
Solar powers the facility and every surplus kilowatt-hour charges the battery instead of being wasted.
Evening peak · 17:00 – 21:00
Shave the peak.
As the sun sets and demand rises, the BESS discharges to cover the peak — cutting expensive grid draw.
Night · 22:00 – 04:00
Power through the night.
Stored energy keeps the site running. When tariffs are lowest, the grid tops the battery up for tomorrow.
Sunrise · 06:00
Ready for a new day.
The cycle repeats — every day, automatically, managed by the EMS.
Why storage
- 01
Energy Cost Optimization
Store energy when it is available or economical and use it when tariffs or demand are higher.
- 02
Peak Load Management
Reduce peak demand charges by discharging stored energy during high-load intervals.
- 03
Backup Power
Support critical loads during grid interruptions and improve operational continuity.
- 04
Renewable Energy Integration
Capture surplus solar generation and dispatch it when production decreases.
- 05
Energy Reliability
Stabilize facility power quality and reduce dependence on fluctuating grid supply.
- 06
Load Shifting
Move energy consumption across time periods to align with operational and tariff goals.
- 07
Grid Support
Help facilities manage demand, reduce strain on supply, and improve energy flexibility.
- 08
Reduced Grid Dependence
Increase self-consumption of on-site generation and lower reliance on grid power alone.
