Ian at MPP Solar, sent me a new board that contained a new charge controller.
Nothing obvious except a pair of wires in a connector didn't seem as if they were snapped into place correctly.
But this is used in a mobile environment, concerned now that things come loose while vehicle is in motion...
Mpp solar 2424 LV HV Hybrid
Worked great for 15 days in smoke filled sky with 4x100w panels in series/parallel produced 30-36v
(Traveling north near Canadian border panels horizontal)
Stopped charging
No panel icon on on display
Batteries in series depleted to 23.7v
AC icon does not “connect” to...
23.7v
Measured at battery posts
Measured at terminals at
As seen on monitor
PV input is 0v on monitor
But no panel icon appears
PV input at panels is now 74.5v
PV input on terminals at controller is 74.5v
Reading were 30-36v working fine all systems go
Charging and discharging
Then nothing...
Thanks for all the help
Can’t find a fuse or any direction for the fuse “replacement”
Also unsure why unless it burned through that would cause it to short no vibration from sitting still
Confusing
But still under warranty
I’ll see what mpp solar can do for me and post their remedy when all is...
