MPPT 75/15 no output :(

Q&A and troubleshooting

Hey! I have an Mppt 75/15 installed in my van and to it I have connected as input a solar charger and the van engine. IT should be loading {And it does} a typical gel battery for a van. From it I have all the van appliances connected in 3 lines, EXCEPT the fridge which after previous glitches is directly connected to the battery.

Well, my problem is, the battery is well charged, the BT says it’s on almost 13V, and nothing works except the fridge {oh curious} which works just fine. For the rest of lights there is no energy. Thou, it’s the controller just not leaving any energy out :frowning:

I am totally new here, just created the account for this problem (this has happened some times but normally it fixed alone after 15-45 minutes, but today it looks like has decided to stay like that).

I. Have screenshots but I don’t see how to attach them.

Drag and drop your screen shots to your screen when typing a new message. Or use the little upload arrow at the top.

The icon with the up arrow is the one to upload image files etc.

Check that the jumper was removed, then try changing the load output to “Always off” then back to always on.
Or try User defined 1, and set up the voltage limits.

Also, I believe the load output should only be used for up to 15 amps. It may be better to install a small DC fuse box from your battery for distribution to your loads.
