Applications

🏠 Residential buildings & single-family homes

The BT51200 is an ideal 10 kWh solar storage for private households. Excess PV electricity is stored during the day and used in the evenings – for greater self-sufficiency and lower electricity costs.

🔌 Upgrading existing photovoltaic systems

Thanks to 51.2 V low-voltage architecture the storage is excellently suited for PV retrofitting, without having to replace existing modules or inverters.

⚡ Wall-mounted backup & emergency power systems

In combination with an appropriate inverter, the BT51200 can be emergency power and backup concepts integrated to reliably power critical loads.

🏢 Commercial & Peak-Shaving

For small businesses, offices or workshops, the storage system load shifting (Peak Shaving) and better utilization of self-generated solar energy.

🌞 Hybrid & off-grid systems

Suitable for Hybrid and island systems, e.g. in holiday homes, agricultural operations, telecom sites or remote installations.

🏷 OEM & system integration

Ideal for OEM customers and system integrators, who want to implement their own wall-mounted ESS solutions or battery cabinets based on a proven 51.2-V module.
