The connection to your battery is interrupted.
Check your wiring, connectors, fuse etc.
If you have a lithium battery with bmv, it might have disconnected you.
They are lithium.. and mppt 75/15
What do you measure with a dvm on the battery and the mppt terminals ?
Your battery voltages are strange.
For a 24V battery to low and for a 12V battery to high.
Give us some more details about your system, maybe some pictures.
The MPPT is connected to a Smart Network; what other devices are in that network?
Check the fuse at the bottom left of the MPPT.
Why, 13.7 is exactly float voltage for 12v lithium ?
The first screenshot shows almost 19V and the history in the 2nd one shows 16/17V and over 24V as battery voltage.
The first screenshots are with the mppt in bulk, the last was in float.
When there is no connection to the battery these are typical voltage levels.
It should not overshoot the configured absorption voltage just because there is no battery*.
That only happens for a second if you suddenly disconnect the battery during the charging but the voltage should go down then.
If you start a MPPT with just PV connected it starts “charging” and goes up to the configured absorption voltage,
Yes, i agree, but the overshoot is registered in the history.
Right now my 100/20 is not connected to the solar panel.
Sometimes i read a panel voltage == battery
Sometimes 5.x v
Sometimes 0
The dvm shows 5.x
I have seen that as well.
There is a fuse at the bottom of the mppt @Rene7 did you check it?
Thanks for ur awsum thoughts everyone.. I did change the settings, from 24v to 12v and it worked proper right after, when I change it, it will show different modes (float..etc.)but always just 0w-1w..I will send more pictures 2morrow as its dark here for now thanks..00
Not yet.. Thank you.. But the mode lights still working and the thing turns on and off.. Hmm
