2. MECHANICAL INSTALLATION.
2.1. POSITIONING THE DEVICE
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.
Angle and spacing of the installation: Make sure the device is installed on a vertical surface and that the following minimum safety
distances are maintained with regard to other elements, in order to ensure optimum ventilation:

3. ELECTRICAL INSTALLATION.
3.1. 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.
DC
Connecting the solar park cables:
Material required:
1. Unscrew the MC4 connectors (supplied) and prepare the cables coming from the junction box of the solar park:
2. Pass the cables through the screw caps, crowns and rubber seals, as shown below. Then crimp the metal terminals to the cables.
To ensure an optimum
connection, use an
approved tool to
crimp the terminals.

8SALICRU
3. 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.
4. 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.
5. 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:
Specifications Inverter model
EQX 5000-2T EQX 8000-2T EQX 10000-2T
Maximum DC input power (W) 5500 8800 11000
Maximum DC input voltage (VDC) 900 1000
Operating range (VDC) 200-800
MPPT range (VDC) 260-800 350-800 400-800
MPPT trackers / inputs per MPPT 2/1
Max. input current per MPPT x no. of MPPTs 10 A x 2 12 A x 2 12,5 A x 2
Max. short-circuit current per MPPT (Isc PV) x no. of MPPTs 11 A x 2 13 A x 2 14 A x 2

6. Connect the cables to the inverter in accordance with the following connection diagrams:
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):

10 SALICRU
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
3.2. 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.

QUICK GUIDE EQUINOX - SOLAR INVERTERS
Connecting the network cables:
1. Unscrew the AC connector (supplied) and prepare the cables coming from the junction box of the power supply:
2. 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.
3. 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.
4. Connect the sleeve to the inverter’s AC connector.
5. Connect the other end of the sleeve to the AC protection in the junction box.
6. Connect the AC part of the junction box downstream of the main automatic circuit breaker for the power supply.

5.3. DISPLAY LED INDICATORS
The LEDs on the display will appear in one of three different
states: on, off, or flashing.
LED off
LED flashing
LED flashing
The inverter uses different combinations of LEDs to indicate dif-
ferent situations:
Status of the LEDs Status of the
inverter Description
Sleep The inverter has no power.
Internal check The inverter has power and it is performing internal checks before
starting up.
Generation The inverter is generating and there are no warnings or error
messages.
Generation
The inverter is generating but there is an active warning or error
message:
- The date/time may not have been set correctly.
- Potential fluctuation in the DC input.
- Potential fluctuation in the mains frequency.
- Possible fan malfunction.
Fault
The inverter interrupts generation and goes into sleep mode due to
anomalies in the mains or power supply:
- Insufficient DC input voltage.
- Mains undervoltage or overvoltage.
- Mains under-frequency or over-frequency.
Fault
The inverter interrupts generation and goes into sleep mode due to a
severe anomaly:
- The inverter's internal temperature is too high.
- Overvoltage in the DC power supply.
Error
The inverter interrupts generation due to an error caused by one of the
following:
- DC bus overvoltage.
- Boost failure.
- Internal AC overcurrent.
- IGBT protection.
- International communications failure.
- Internal relay failure.
- Internal memory failure.
- Short circuit in the inverter output.
Error
EThe inverter interrupts generation due to a serious error caused by
one of the following:
- Low isolation impedance.
- High leakage current.
- DC injected into the mains.
- Overcurrent in the DC input.
- DC polarity inverted.
