Hi all I have mppt 75/15 I run my fridge of a leisure battery but every night it goes down and in the morning I have to go to my app and reset to default settings to get it all back up and running maybe I have set it up properly so some help would be much appreciated

Is your battery big enough? Sounds like its too small

[image] Casper: reset to default settings But then you set custom settings again? How would resetting to default settings change anything if its already the default settings? 115Ah is about the same as i have in my 4x4 as the aux battery, and im able to run the compressor freezer for several…

Not that I’m aware off I do have the app with history on it

Please post the settings from the app, press the cogwheel for that

Hi I pressed the cogwheel then which one do you need me to post battery, load output, streetlight,TX PORT FUNCTION, rx port function, or VE smart networking

post battery settings please. Also any history.

Are you using the load output to run the fridge? If so, then connect the fridge directly to the battery. The load outputs dont like inrush currents. I cant run my compressor freezer rated at 4A on the 15A load output for example

Mppt keep going down
