Thank you again for your input. I still have issues with this battery. It is a second time that charging quickly goes into float state after couple hours of moderate use (windows laptop 10-50W, 80Wh consumed since last top up as per VictronConnect) so it must be drained some. What could be the...
Ok, I think I have an imperfect set of (flexible) panels
Could you please help me understand its configuration?
I assume there are 2 serially wired sets of 12 parallel 9V strings (giving 18V panel)
I have correct open circuit voltage but lower than expected current flow
I have found places...
Ok, there was a cold solder on battery positive terminal of smart solar mppt wire connector; thank you victron's manufacturing plant; I hope it ends my journey with this mppt brick/solar setup
Hi, I have recently bought
basic LiTime 100Ah battery
After couple of days of uninterrupted usage yesterday I got cut off from the cells by BMS just by plugging 5W usb charger (through smart solar).
What could be the reason? The day before I have fully charged it (next pic).
LiTime support is...
How fast does it act? Why no burn marks?
Yes I was also curious why charging last only couple of minutes after reaching 14.4V. I have tail current set to 2A and absorption fixed of 24h. Could I somehow prolong charging?
Can you please recalculate it for today? Now when I have corrected bad solder point I do not get voltage drops while moving the cables which is good but I am still at 130W from both panels at once in a clear sky (~50%)
Ok then I am assuming a short (waiting for better connectors currently)
I knew that going below 2A will terminate it so I have set time to the max available.
Charge drop took couple of minutes.
I am charging below 10A. I have another issue of getting 150W max from nominal 2x140W panels. I...
Ok. I will give it a try.
Tessaloniki, Greece
Mobile so always aimed at the Sun.
18.7V
7.5A
In series so 40V/7.5A max
75/15 so within the limits (limited by thermals only)
