Motorhome system mppt 75/15 not starting up daily until rebooting
hello
in the first screen shot, the voltage is not enought hight to sart the mppt (you need +5 V above battery voltage)
when you reset, may be the pv voltage was a litle more higher so enouth to start !
each time i see this it was a pv problem !
Thank you for your reply
Today was the same experience, no o/p at 16.63v until I rebooted the system and then ok.
The battery was 12.79v so again there was no 5v difference to start up automaticall.
The off load panel voltage was 22.5v incidentally
There doesn’t seem to be much I can do other than waiting for the battery to drop in voltage or the sun to shine stronger, (something that seldom happens in the uk at this time of the year)
it has been suggested I consider an additional pv panel in series to double the voltage!
