Mounting process
Material required

Steps to follow:
ELECTRICAL INSTALLATION
DC (DIRECT CURRENT) INSTALLATION
Make sure the inverter’s isolator switch is in the OFF position.
Make sure the protection systems in the junction box are activated and that there is no voltage in the cables you are going to handle.
Connecting the solar park cables:
Material required:
- Unscrew the MC4 connectors (supplied) and prepare the cables coming from the junction box of the solar park:

- Pass the cables through the screw caps, crowns and rubber seals, as shown below. Then crimp the metal terminals to the cables.

- Insert the metal terminals into the MC4 connectors, until you hear a click. Once this is done, pull gently on the cable to make sure it is correctly attached.
- Screw the cap onto the body of each connector, making sure all of the elements fit together perfectly and that the rubber seals seal the cable with the connector:

Use the special spanners for MC4 connectors in order to ensure optimum tightening without damaging the connectors. - Check the polarity and voltage of the photovoltaic panels before connecting them to the inverter, in line with the values shown in the following table:

Connection process for facilities with solar parks of varying power (panels with different orientations and/or strings of different lengths):
If the facility’s solar panels are not on the same level, i.e. they are exposed to different levels of radiation (whether due to the shape of the roof, differences in inclination, or different string lengths), the connection process must be carried out as follows:
The devices allow for a maximum solar power imbalance of 40%-60%.
Connection process for facilities with a single solar park (i.e. panels with the same orientation and strings of the same length):
For facilities where all of the power is in the same solar park, the power must be distributed between the two tracks, joining both inverter inputs as shown in the diagram below:
This configuration requires modification of the “Adjust Model” parameter on the device. Refer to the section titled “Changing the MPPT Model” (Page 17).
Strings that can be connected to each MPPT, depending on the device model:
| Model | String / MPPT |
| EQX 5000-2T | 1/2 |
| EQX 8000-2T | 1/2 |
| EQX 10000-2T | 1/2 |
AC (ALTERNATING CURRENT) INSTALLATION
Make sure the protection systems in the junction box are activated and that there is no voltage in the cables you are going to handle.
If you are installing the optional ESM3T EQX energy meter, we recommend installing the inverter as near to the electrical connection as possible, in order to avoid extending the RS485 communications cable.
Material required:
Connecting the network cables
- Unscrew the AC connector (supplied) and prepare the cables coming from the junction box of the power supply:

- Pass the cables through the screw cap, crown and rubber seal, as shown below. To optimise the connection, we recommend crimping the terminals at the ends of the cables.

- Insert and screw the cables to the corresponding terminals on the connector: R phase, S phase, T phase and earth (G). Once this is done, pull gently on the cables to make sure they are firmly attached.
- Connect the sleeve to the inverter’s AC connector.
- Connect the other end of the sleeve to the AC protection in the junction box.
- Connect the AC part of the junction box downstream of the main automatic circuit breaker for the power supply.
