question

Good work Guy. I mean *really* good work. Don't stop now...

Excellent work! It's a great place to share and learn, plus I have made new friends too!

Hi Guy maybe you can answer this one as it seems to be related to how the unit works.

HI, I have a smart controller Mppt 100/20 controller in my caravan. Since installation I have noticed that when connecting any item , by either a connection to a 12v lighter connection or installing fuses, that the 12v output from the controller drops to OFF state for a period of about 1 sec then turns on again. With the solar panels , 2 x 180w outputting about 20v, disconnected this does not happen. In this state I can see from the app that when the TV for example is connected to a 12v power that the surge current is about 300ma. This would seem to be too low to trigger short circuit protection levels. The controller is set for loadcontrol of smart battery and no links inserted. The problem is not load dependant, that is the load output drops to OFF with all lights , fans etc on or off when a TV is connected to 12v point.. Max load with everything running is about 8amps which is well within the specs for the unit. The unit has a direct connection to the RV battery. Measuring battery voltage at BAtt connection points shows no drop in voltage. There does seem to be some voltage change at the output terminals when the issue happens but its hard to see if its related to the output being turned off. Any help appreciated.
