You will find below against the standard connection of batteries for use with the engines of the current range in 24V.

Step 1: Measure solar panel voltage

Equip yourself with a multimeter and position the voltage measurement (Vdc). If you are equipped with a calibre multimeter, position the wheel on 200V.


Prior condition:

Solar panel: Connected

Batteries: Branched

Position the multimeter probes on the SOLAR IN input on the MPPT card.

Put the red probe (V) on SOLAR IN + and the black probe (COM) on SOLAR IN -.

  • Verify that the value displayed on the multimeter is positive (no - displayed to the left of the value raised.

Correct the connection polarity of the panel if necessary

  • Expected voltage (variable according to sunshine):Maximum 45VDC

If the displayed voltage is around 5V, the panel does not produce enough energy for charging batteries. Check the orientation and sunshine of the panel. The charging current of the batteries is then 0mA. Batteries will not be recharged.

Disconnect the solar panel from the MPPT card and measure the voltage at the wires from the panel.

  • Expected voltage (variable according to sunshine):Maximum 45VDC

Step 2: Measure the short-circuit current of the solar panel

Equip yourself with a multimeter and position the current measurement (A)

Position the red probe on the 10 A input of the multimeter

Prior condition:

Solar Panel: Unplugged

Measure either at the panel or at the level of the wires arriving at the MPPT card by positioning one probe per wire.

Expected current (variable according to sunshine):Maximum 500mA

Then connect the solar panel again to the MPPT card.

Step 3: Measurement of battery voltage

Equip yourself with a multimeter and position the voltage measurement (Vdc). If you are equipped with a calibre multimeter, position the knob on 20V.


Prior condition:

Batteries: Unplug

Position the probes on each terminal of the battery.

Expected voltage: Between 12.1V and 13V

In the case of a lower voltage, the battery has a malfunction.

If the battery is 12V, plug a 12V device into the battery and see if the voltage drops or remains stable.

Step 4: Measurement of charging voltage

Equip yourself with a multimeter and position the voltage measurement (Vdc). If you are equipped with a calibre multimeter, position the wheel on 200V.


Prior condition:

Solar panel: Connected

Batteries: Unplug

Position the multimeter probes on BATTERY + and -.

Expected voltage: 27VDC

If you release 0V, the MPPT card fails.

Step 5: Measurement of charging current

Equip yourself with a multimeter and position the current measurement (A)

Position the red probe on the 10 A input of the multimeter

Prior condition

Solar panel: Connected

Batteries: Branched

Motorization: Disconnected

Unplug one of the pods from one of the batteries.

Position one probe on the free lug, and the other probe on the battery terminal that is free.

Expected current (variable according to battery charge demand and sunshine): Between 50mA and 300mA approximately

If you do not measure any current, the MPPT card fails.

If the current varies (increase or decrease) it is just that the MPPT card calculates the best charging current.

Step 6: Measurement of the output voltage Motorization

Equip yourself with a multimeter and position the voltage measurement (Vdc). If you are equipped with a calibre multimeter, position the wheel on 200V.


Prior condition:

Batteries: Branched

Position the probes on the MOTORISATION output terminals of the MPPT card

Expected voltage: 27VDC

If you measure 0V, the MPPT card is HS.

In order to verify that the connection is good between the MPPT card and the motorization:

Position the probes on the metal blades of the connector (for AVLO Battant 24V cards)

Expected voltage: 27VDC

If you measure 0V, check the link between the MPPT card and the connector.

Step 7: Measurement of electronic card consumption

Equip yourself with a multimeter and position the current measurement (mA)


Prior condition

Batteries: Branched

Motorization: Branched

Unplug one of the pods from one of the batteries.

Position one probe on the free lug, and the other probe on the battery terminal that is free.

Expected current:

  • AVLO Battants 24V

Card out of standby but without motor movement (green light on): 42mA

Standby card (green off): 0uA (not measurable by multimeters)

  • CA2B9SL Cold 24V

Out of standby card but without motor movement (green light on): 35mA

Standby card (green off): 0 uA (not measurable by multimeters)

If the current value increases briefly, it is just that the electronic card picked up a 433.92MHz radio signal during measurement.

Step 8: Measurement of MPPT card consumption

Equip yourself with a multimeter and position the current measurement (uA)


Prior condition:

Solar panel: Connected

Batteries: Unplug

Motorization: Disconnected

Unplug the red thread from SOLAR IN

Position a multimeter probe on the red wire from the solar panel, and position the other probe of the multimeter on the SOLAR IN + terminal of the MPPT card

Expected current: between 3uA and 8uA

If the current is 0mA, the MPPT card is out of service

Attention!

Under no circumstances should use the transformer fuse door to make a connection between the solar kit and the gate motorization.

Otherwise there will be a permanent discharge current in the coil of the transformer, which will have the effect of discharging the batteries prematurely.

Attention!

The orientation of the panel must imperatively be SOUTH (SUD OUEST to a lesser extent)

Solar panel must be inclined at 30°

The Sun must directly hit the solar panel. In case of overcast sky, the load will be much lower or even zero depending on the cloud cover.

In case of shade on the solar panel, even partial, there will be no charge of the batteries.

ENTRETIEN
Entretien

Regularly clean the solar panel with a soft, dry cloth

Check battery voltages regularly.

It is advisable to charge the batteries using a dedicated charger before winter arrives and sometimes while if you notice a loss of speed.

It is imperative to unplug the batteries from the solar kit in case of charging
