Procedure:
1) Prepare the positive and negative PV cables.
Insert the crimped positive and negative cables into the corresponding photovoltaic connectors.
1. Positive contact
2. Negative contact
3. Positive connector
4. Negative connector
Make sure that all the DC string parameters are acceptable to the inverter in accordance with the technical
specifications given in the datasheet and in the Azzurro ZCS configurator.
In addition, check that the polarities of the photovoltaic cables are correct. Insert the positive and negative
connectors of the HYD-ES inverter until you hear a “click.”
Use a MC4 wrench to disconnect
the photovoltaic connectors
NOTE : Both MPPT inputs of the inverter should be populated, even if the system only
has one string.
Use a “Y” cable or a square to split the string.
Configure the inverter in parallel MPPT mode directly from the display.
11. PV CONNECTION
NOTE : Before connecting/disconnecting the strings to the inverter, check that the DC circuit
breaker on the side of the inverter is in the OFF position.
Before removing the positive and negative PV connectors, make
sure that the DC rotary circuit breaker is in the OFF position.
