Reference project

Tenant-Generated Electricity in Residential Properties

A 1960s apartment building is becoming a showcase for sustainable living. With a 21.5 kWp solar system, a heat pump, and a Voltfang battery storage system, it demonstrates how modern, self-sufficient, and energy-efficient living can be achieved.

2nd Life batteries will help conserve resources over the next 20 years

Implemented use case

In this modernized building, self-consumption was optimized to improve energy efficiency. With the help of our advanced energy management system, we ensured that the electricity generated by a 21.5 kWp photovoltaic system was efficiently used to meet the tenants’ own energy needs. This reduced energy costs and contributed to sustainability.

Aim of the project

In cooperation with our partner solarize, Voltfang is implementing a tenant electricity model that supplies the energy-efficient residential building—including its heat pump—with green electricity. The existing building utility connection is supported by a virtual total meter.

Our customized solution

The battery storage system was delivered with a usable capacity of 58 kWh and a power output of 30 kW. The battery storage system is equipped with compatible inverters to ensure efficient power conversion.
