If you are doing solar you probably will like Anderson PowerPole connectors. I have decided these are the connectors that I want to use and currently using now.
Part of the reason for this decision is that I had to use them to use my current Lion LT solar generator. I had never used them before. As you can see they are divided into colors and each color is clearly labeled with the polarity it carries. What this means is that it is easy to remember which is positive and which is negative. You don’t have to know much about electricity to know that the color should plug into the same color.
One of the other neat things about this is the design of it. If you look carefully on the side you will see a rectangle of plastic that pokes out of the side. What this means is that you can uncouple the red side by sliding it from the front to the back and switch the side it is on. You can not only change the side, but you can change the direction of the plug. So this means that you can plug it into a wide variety of cables. I rather enjoy moving these adapters. It is fun to have that flexibility and design.
What I like about this the most though is the size of the cable. I shared before how I bought an adapter that was a huge diameter. I didn’t have much choice because that was an unusual adapter at both ends. However with this the cable is so small and it directly helps me. I am able to close the window and have a very small/almost closed profile of the window. That means that it allows even less air into my room, and during Winter will significantly make the energy loss less. I have also ordered some insulation that I will use to seal the gap and I don’t expect any air intrusion when I hang out the panels. The adapter cost me $20 but it will save hundreds in energy/heat not wasted and also quieter due to the noise being muffled.
The other adapter/cable I bought cost $100 for all the adapters I needed to make it work, but it is not wasted money. It will be a great backup cable, or cable if I need to use it outdoors. It also let me experience other types of connectors like DC 5.5mm, MC4, and Anderson SB50. Those are interesting, but have their own pros/cons. I like this one the best.
Once I plugged it in I also noticed that the solar generator charged up faster than it did in the past. Therefore I have to conclude that all of those adapters and the much longer length must have reduced the amount of voltage/current running through it. With DC is is always recommended to keep the distances as short as possible to minimize losses so now I have done this. I am so pleased with how this is working out.
