CONNECTION OF VARIOUS PANELS (FOLLOWING)
CONNECTION IN PARALLEL
For this installation, double solar connectors especially made for parallel mounting are necessary.
Never install more than 3 panels in parallel.
Panels must be of the same power.
• Check that the panels power does not go over the one accepted by your charge
regulator.
Connect the regulator to the battery.
•
Connect all the panels positive cables (red) to the positive double solar
•
connector (red), and all the negative cables (black) to the negative solar
connectors (black).
Connect the panels to the charge regulator.
•
To make the panel/regulator/battery connection, we recommend our ready-to-use
UNICONNECT kit, to optimize your electrical performances and simplify the
mounting process.
In this case, the two 100W solar panels connected in series will give the regulator:
200W, 17,6V and 11,24A.
In an installation in parallel, the panels intensities are added, but the voltage stays the same.
Ex : If a panel is in the shadow and produces only 1A but the
other one produces 5A, the final intensity produced will be 6A.
In an installation using 2 or 3 panels, parallel coupling will
guarantee an optimum production, especially in case of shadow.
