SOLAR PANEL/S CABLE CONNECTION
IMPORTANT: DO NOT connect solar panels that have inbuilt regulators or use a supplementary external
regulator. The Manager has an inbuilt regulator that may not function correctly if regulated solar panels are
connected.
The Manager 50/75/100 will always draw as much power as possible from solar and is capable of drawing
power from multiple solar panels with large solar arrays, which can be congured in a combination of parallel
connections. Ensure the open circuit voltage of the solar panel array is below the maximum solar input
voltage rating of the Manager at minimum ambient temperature (see 'Electrical Specications' (page47)).
See 'Connecting Multiple Solar Panels' (page31) when connecting more than two solar panels in your
system.
When connecting 1– 2 solar panels it is important the solar connection meets the following requirements:
The solar panel ground is connected to a common ground point (i.e. common ground busbar).
The solar cable gauge is capable of carrying the combined short circuit capacity of both panels.
