Does not draw voltage mppt blue solar 75v / 15

Good afternoon. I have a regulator connected to a solar panel and a battery. It has been working perfectly for me to light two 12v bulbs in a country house.


I have noticed that there is no voltage coming out of the LOAD output. I disconnect the fuses from the loose board the battery and reconnect everything. It takes voltage out of LOAD for 3 or 4 minutes and stops doing it. I have looked at the fuse on the regulator and it is fine.


I discard the battery because I have tried two and the same thing happens to me.


What can happen to him?


Thank you very much

What are your settings for the load output on the mppt?

If your have a multimeter you can check your battery with it.

This will make your life easier with victron connect.

Are there some jumpers at the bottom, these can set cut off voltages.

A manual may also help.
