As I mentioned, my concern is the correct tending of the battery. The charge controller specification says that it handles the "Bulk, Boost, Float, and Equalization" charges. If I put a battery charger on the battery, then I may well defeat the variation required for tending the battery. I'll...

Your suggestion to clip the battery charger to the battery is not right. The charger output would be feeding into the charge controller output. You need diode isolation. You can't put two power sources in parallel without isolation. I don't want to have to worry about the charger doing the...

I'm putting together a small solar system, 2-100w panels and a Renogy charge controller and a single 100AH SLA battery. I'm not planning on a lot of bright sun here in SE Minnesota, especially during the winter months so I may well need some supplementary battery charging for my 12v power...

Interesting discussion! This is a very small - at home - installation, 2-100 watt panels, more or less for hobby at this point (getting my feet wet). As I mentioned before, they will be roof mounted (very low slope, easy access). One problem is that we are in a Mississippi River valley...

Thanks AmyG, those links were a great deal of help. I guess that I just didn't know that it was referred to as "solar tracker". Make sense though. I'm actually surprised that tracking the sun doesn't make as much difference as I thought that it would. TacomaJoe, you referred to the "SOC"...

I'm just setting up a 200w solar panel and 100AH SLA battery and considering adding a linear actuator to keep the solar panels turned toward the sun throughout the day. What do I measure for maximum charge to the charge controller, the voltage or the current? Is there any reason that I can't...
