I'm at the very beginning of my experience with solar energy and Victron.
That's why I ask you for help here - and apologize if the question is too trivial for you.
I have a very simple setup:
12V lifepo 30ah battery and Smart Solar MPPT 75/15.
Battery configured as lifepo with 12V.
Otherwise everything left by default.
For a first test with a 100W panel the battery was fully charged.
Street light function activated (or always on?).
At the load output of the SmartSolar I had connected 2x 20W halogen lamp as a powerful consumer.
My calculation was rough:
30ah at 12V is about 360Wh.
At about 40W, this should be enough for 9h - one night.
Overnight, I had left the consumers on to see what capacity the battery has.
The next morning the app showed me: Battery min: 0.07V.
(see the attached screenshot)
Now my question(s):
Had the voltage really dropped to 0.07V?
With such a low voltage, could the SmartSolar still write data itself?
Should the SmartSolar not ensure that there is no deep discharge?
Is my battery now non-reversible broken? What can I do to prevent deep discharge?
I thought the SmartSolar would do prevent that.
Thank you in advance for your help.
