EpEver/EpSolar MT50 Remote Display: Overview

Answering viewer requests for an "all-in-one" video showing all the screens and settings on my EpSolar/EpEver charge controller with the MT50 remote display.

I have 2 of these controllers and displays, one 20A and the other 40A. This video focuses on the 20A/12V setup in my garden shed. The system has 2 strings of 2 - 60W and 2 - 15W panels in parallel, giving ~43Voc and 3.5Isc and 150W. Batteries are 26AH and 12AH AGM/sealed units in parallel for 30AH total capacity. They are in parallel since the capacities are different and I need to be able to remove either one to use it elsewhere.

The lights and fans in shed are powered off the DC Load terminals of the charge controller. This way, if a light is left on by mistake, the controller will shut off the load output below the low voltage disconnect level. The DC Load output also records energy consumption, which I track on a monthly basis.

Many people do not understand the DC Load feature and instead connect things directly to the battery. This is fine for heavy loads like a power inverter. But for smaller loads like lights, fans, and other electronics, the DC Load output will help protect the battery from over discharge. These controllers were originally designed for lighting applications and the DC Load feature has a many options for "On at Sunset"and "Off at xyzHours" for use in controlling lights at night. I think this scares off many people, especially if you have to look up up a number in a table to select on the controller. I always select the "Manual Control" option (usually the last option in the table!) and then the "Esc" key gives a simple on/off control for the load. All the controllers I've used have a 20A maximum DC Load output rating. They will shut off if that current is exceeded. If you wanted to control a higher current load, it's easy to wire up a DC relay to that output. Have the relay then switch battery current on and off to the higher current device.

See the video card links to videos with more details on the various screens.
