Demands：
A site in Eastern Europe needed backup power when its solar PV system was not generating electricity. The battery storage system had to supply on-site loads in off-grid mode and be available in time for the planned installation.
Solution：
PVB supplied two 100 kW / 241 kWh all-in-one air-cooled energy storage systems. Each unit features ≥90% system energy efficiency, an IP55-rated enclosure, and an operating temperature range of −30°C to +50°C. A transfer cabinet enables switching between grid-connected and off-grid operation.
Feedback：
The customer noted that having both units in stock at PVB’s European warehouse made it easy to arrange collection around the project schedule. Direct pickup helped the team get the equipment to the site quickly and proceed with installation.
