Hello everyone,
My system off-grid assisted is programmed to only charge with solar and don't discharge my 3 Growatt batteries more than 30%. At night I turn on my AC. The expected behavior is that AC runs off the batteries and when reaches 30% start using grid power. This is what I think I configured.
Setings:
01 SBU (priority is solar, battery, grid)
12 B2AC (back to grid power) set to 30%
14 Charge source priority: OSO (Only charge with solar)
LAst night I added 2 more batteries. Total 3. They stabilized at 60% overall. Turned on my AC and as expected all power came from batteries. Went to bed. Woke up at 6 am with a beeping alarm. Fault 04 Battery to low. The batteries were at 28 %. Then I noticed that it is charging with grid electricity. It should not because of setting 14.
Now the batteries are at 44% and keep charging. Curious to see what will happen when the sun hit the panels in about one hour. Did I forget a setting? Any suggestions? Thank you.
