PV Home Storage#
Storing the energy generated by the photovoltaic panels is becoming increasingly cheaper. More and more providers of PV home storages share a rapidly growing market: A variety of storage models is available. But do the values from the data sheet correspond to reality? Does the storage system keeps the promise of the manufacturer? Which safety measures are included in the storage? What is the actual efficiency of the system and will it cope with the predicted cycles? Fraunhofer ISE helps to capture the topics of security and efficiency of storages with high quality. According to the BVES guidelines for PV home storage systems, we test systems holistically. In our modern laboratories several storage systems can be tested simultaneously in HIL test benches (Hardware-in-the-Loop). In long-term tests, we carry out aging tests which are performed with realistic high-resolution load profiles at reproducible adjustable climate conditions.
