A SMALL CONNECTOR PROJECT

When I added the 48 volt solar panels to the bimini project I needed a way to connect both the 12 volt panels and 48 volt panels to their appropriate battery banks. So I rigged up a temporary junction box using a barrier strip and a small plastic project box as a temporary install. Here is what I had and it has work pretty good over the years.

 Well several years later I'm getting around to an upgrade . I'm finally getting around to making a better way to connect the solar panels to the solar controllers using Anderson Powerpole connectors. Like the ones shown here:

The blue connector signifies that the voltage the wires are carrying is 48 volts and is used to charge my electric propulsion battery bank. Speaking of colors notice how the red color has faded from this wire:

Exposure over the years has caused it to almost become white in color. Another good reason to have color coded connectors like Powerpoles on the ends of the wires.

 The Anderson Powerpole connectors can also be mated as shown here:

 This assures the proper ground (black connector) travel with the positive voltage wire. This helps to eliminate confusion with different voltage systems. You can also buy an optional clip that locks the pairs of Powerpole connectors to add some extra security that they won't pull apart.

So after replacing the lug connectors with Powerpoles I also put a little dab of Marine Goop on the back of each connector to help seal the wire and connectors.

Now both the 48 volt  and 12 volt solar panel connections can be easily accessed for troubleshooting and testing. I have plans to put some instrumentation in line to measure how well the panels are doing in the near future and I will post about those tests here on the blog.
