The installation method for DC connector.
To better dustproof and waterproof the internal inverter, all DC connectors provided in the
accessory bag should be connected to the inverter. If only some of the DC connectors are used,
the DC connectors without connection should be blocked with a non-conductive insulator.
This function is only for local firmware upgrades and parameter calibrations.

The RS485 port of the inverter is used to connect the EzLogger Pro, and the total length of
connecting cable should not exceed 1000m.
