Checkbox 500V (4,240,155)

The Fronius Checkbox 500V ensures your storage system’s operational reliability, even in exceptional situations. Compatible with the Fronius Symo Hybrid, and LG Chem Resu batteries. As the battery is designed for 500 V while the inverter is designed for 1000 V, the Fronius Checkbox 500V measures the incoming voltage and disjoins the battery in the unlikely occurrence where the system fails.
