11.7 Line choke
The line choke can be used as an option:
• To support overvoltage protection
• To smoothen the line current
• For protection in the event of distorted line voltage
• To limit the charging current, for example, when several inverters are connected
together in parallel on the input end (nominal current of line choke = total of nom-
inal input currents)
11.7.1 UL and cUL approval
The listed line chokes have cRUus approvals independent of the inverter.
