50a mppt charge controller

   Most charge controllers have three sets of terminals. One set goes to the battery. One set goes to the solar panels. That’s pretty self-explanatory.

   The third set usually says LOAD or LVD. #solar charger controller mppt          This output is designed to be a level of battery protection and there are two schools of thought on this. But first, where do these wires go?                                                                                                                                                                           

   The load output is meant to power all of your small electronics through the charge controller. #mppt 100a        So you’d have the (+) wire run to a DC fuse box that is connected to your lights, refrigerator, usb chargers, etc. And the (-) wire connects to a bus bar for the return wires of all these electronics.

  If the batteries drop below a certain voltage, the solar charge controller will cut power to the fuse box to protect your batteries from being drained further.                                                                                  

   Some smart charge controllers will adjust this voltage cutoff if your batteries aren’t getting full charge daily. This is how wiring to the load terminals looks (fuses omitted)
