In this tutorial, we will look at the measurement points to be carried out in order to check that the solar kit Avidsen 114375 is working properly.
You will find opposite the terminal correspondences on the MPPT board of the solar kit
See connection for a list of batteries for use with the current range of 24V engines.
Take a multimeter and set it to measure voltage (Vdc). If you have a multimeter with a gauge, set the dial to 200V.
Position the multimeter probes on the SOLAR IN input on the MPPT board.
Connect the red probe (V) to SOLAR IN + and the black probe (COM) to SOLAR IN -.
Correct the polarity of connection panel if necessary.
If the voltage displayed is around 5V, panel is not producing enough energy to charge the batteries. Check the orientation and sunlight of panel. The battery charging current is 0mA. The batteries will not be charged.
Disconnect the solar panel from the MPPT board and measure the voltage on the wires coming from panel.
Take a multimeter and set it to measure current (A)
Position the red probe on the multimeter’s 10 A input.
Measure either at panel or on the wires arriving at the MPPT board, positioning one probe per wire.
Expected current (variable according to sunshine): Maximum 500mA
Then reconnect the solar panel to the MPPT board.
Take a multimeter and set it to measure voltage (Vdc). If you have a multimeter with a gauge, set the dial to 20V.
Position the probes on each battery terminal.
Expected voltage: Between 12.1V and 13V
If the voltage is lower, the battery is malfunctioning.
If the battery is at 12V, connect a 12V device to the battery and check whether the voltage drops or remains stable.
Take a multimeter and set it to measure voltage (Vdc). If you have a multimeter with a gauge, set the dial to 200V.
Set multimeter probes to BATTERY + and -.
Expected voltage: 27VDC
If you read 0V, the MPPT board has failed.
Take a multimeter and set it to measure current (A)
Position the red probe on the multimeter’s 10 A input.
Disconnect one of the battery terminals.
Position one probe on the free terminal, and the other probe on the free battery terminal.
Expected current (variable according to battery charge demand and sunshine): Between 50mA and 300mA approx.
If you don’t measure any current, the MPPT board is faulty.
If the current varies (increase or decrease), it’s just that the MPPT board is calculating the best charging current.
Take a multimeter and set it to measure voltage (Vdc). If you have a multimeter with a gauge, set the dial to 200V.
Position the sensors on the MOTORIZATION output terminals of the MPPT board.
Expected voltage: 27VDC
If you measure 0V, the MPPT board is out of order.
To check that the connection between the MPPT board and the actuator is correct:
Position the probes on the metal fins of the connector (for AVLO Battant 24V boards)
Expected voltage: 27VDC
If you measure 0V, check the connection between the MPPT board and the connector.
Take a multimeter and set it to measure current (mA).
Disconnect one of the battery terminals.
Place one probe on the free terminal, and the other probe on the free battery terminal.
Current expected:
Card in standby mode but without motor movement (green light on): 42mA
Card in standby (green LED off): 3.2mA
Card in standby mode but without motor movement (green light on): 35mA
Card in standby mode (green LED off): 2mA
If the current value rises briefly, it’s because the electronic board has picked up a 433.92MHz radio signal during measurement.
Take a multimeter and set it to measure current (mA).
Disconnect the red wire from SOLAR IN
Position one multimeter probe on the red origin wire of solar panel, and position the other multimeter probe on the SOLAR IN + terminal of the MPPT board
Expected current: 8mA
If the current is 0mA, the MPPT board is out of order.
Under no circumstances should the transformer’s fuse holder be used to make the connection between the solar kit and the gate operator.
Otherwise a permanent discharge current will flow through the transformer coil, discharging the batteries prematurely.
panel must be south-facing (south-west to a lesser extent).
solar panel must be inclined at 30°.
The sun must strike solar panel directly. On overcast days, the load will be much lower, or even zero, depending on cloud cover.
If there is even partial shade at solar panel, the batteries will not be charged.
Regularly clean the solar panel with a soft, dry cloth
Regularly check battery voltages.
recommended Batteries should be recharged with a dedicated charger before the onset of winter, and sometimes during if you notice a loss of speed.
Batteries must be disconnected from the solar kit when recharging.
