MPPT controller timer settings (1 Viewer)

[Xan]

New solar kit now freshly installed.

MPPT controller is one of these

Currently have left everything on factory settings, should I change anything?

As far as I'm aware, you set the timers both to n = not used or something like that.

I believe they refer to the terminals labelled 9. These are not used in my installation and I believe they can be used for attaching timed lights or similar.

It depends if you have a load connected or not. The battery discharge level set to 10.5V I think is too low for comfort 11.9 is a discharged battery 10.5v and if you do not charge fairly soon you could kill the battery. The load is on a timer unless you select manual and have it on permanently. If no load is connected then you lose the over discharge protection.

wot roger sed !

set battery type to your particular battery type..gel, lead acic etc then leave alone.

the timer mode is for night lighting etc and will turn on and off a porch light etc if connected.
it does nothing when the panel is providing charge current...only works at night or if the panel is covered etc...and will only provide maybe a couple of amps max.

The battery cut off voltage will be UNDER LOAD and does not reflect the state of charge.
