Fronius Checkbox 500V

The Fronius Checkbox 500V guarantees the operational reliability of the storage solution with Fronius Symo Hybrid and the compatible LG Chem RESU batteries - even in exceptional situations. As the battery is designed for 500 V and the inverter is designed for 1000 V, the Fronius Checkbox 500V measures the voltage and disjoins the battery in the unlikely case of failure.
