CONNECTION OF VARIOUS PANELS
To increase your panels total power, you can connect various ones in a series-parallel installation.
The 90cm length cables are equipped with fast solar connectors making the connection easier.
Never connect more than 3 panels in parallel. The panels accept until 2 times their
power in return current.
Check that your panels power does not go over the power accepted by your charge
regulator.
Follow the connection order mentioned earlier.
CONNECTION IN SERIES
For this installation, the panels must be of the same electrical
characteristics: power, voltage and intensity (+/-5%).
Check that the panels power does not go over the charge voltage
•
accepted by your charge regulator.
• Connect the regulator to the battery.
• Connect the first panel positive connector (red) to the second
panel negative connector (black).
Connect the panels to the charge regulator.
•
In a series installation, voltages are added, but the total output current is
equivalent to the weakest of the panels.
In this case, the two 100W solar panels connected in series will give the regulator: 200W, 35,2V and 5,62A.
Example : If one of the panels is in the shadow and produces only 1A, even if the other panel produces 5A, the
total output current will be equivalent to the weakest, meaning 1A.
