Data Sheet

02. WHY CHOOSE A COOL ENERGY BATTERY STORAGE SYSTEM?

Cool Energy battery storage systems are engineered to optimise energy usage by storing surplus electricity for later use. They support both on-grid and off-grid operation, helping reduce grid dependency, increase solar self-consumption, and improve overall energy efficiency.

03. DOES THE SYSTEM WORK WITH SOLAR PANELS AND THE GRID?

Yes. Cool Energy systems integrate with solar PV to store excess generation and can also charge from the grid. This enables off-peak charging and peak-time usage, helping to reduce energy costs.

04. WILL IT PROVIDE BACKUP POWER DURING A POWER CUT?

Yes. Built-in emergency power supply (EPS) functionality allows the system to automatically switch to battery power during a grid outage, supplying essential loads without the need for additional external switching equipment.

05. IS THE SYSTEM SAFE AND SUITABLE FOR INDOOR OR OUTDOOR INSTALLATION?

The system uses lithium iron phosphate (LFP) battery technology and low-voltage architecture for enhanced safety and longevity. Its compact, wall-mounted design and robust environmental protection allow installation in a wide range of indoor or outdoor locations, subject to site conditions.

06. CAN THE SYSTEM BE EXPANDED AS MY ENERGY NEEDS CHANGE?

Yes. Cool Energy battery storage systems feature a modular design, allowing storage capacity to be expanded over time as energy usage increases or additional solar generation is added.

07. WHAT INSTALLATION AND ELECTRICAL CONFIGURATIONS ARE SUPPORTED?

Cool Energy systems support flexible installation options, including AC and DC coupling, and can be configured as all-in-one or modular systems depending on site requirements. Adjustable power output and compatibility with common grid standards help simplify system design and commissioning.

08. HOW IS THE SYSTEM MONITORED AND CONTROLLED?

The system can be monitored and managed via a smart app using wireless connectivity. This allows users to view battery status, energy flow, and system performance in real time, helping to optimise usage and identify issues quickly.

09. IS THE SYSTEM DESIGNED TO MEET UK SAFETY AND GRID COMPLIANCE REQUIREMENTS?

Yes. Cool Energy systems are engineered to comply with applicable UK and international standards covering battery safety, inverter operation, and grid connection. Integrated protection features, certified components, and compatibility with common DNO requirements help simplify installation, commissioning, and regulatory sign-off.
