Question: what are the pros and cons for my settings if I use 1 x 4 panel in series 4 x 23.9V = 95.6V :arrow_right: 95.6V / 10.74A …or if I use 2 x 2 panel in series/parallel 2 x 23.9V = 47.8V, 2 x 10.74 = 21.48A :arrow_right: 47.8V / 21.48A I know that both needs different parameter MPPT contr…

If the values are set correctly, the shunt recognises the full charge at some point and corrects the SOC to 100% ooops … but you have Settings to show us … ?

The first thing you notice is that the temperature compensation is switched off. For a battery that is ‘almost’ outside, this should be included. However, this is where the manufacturer’s data comes into play again … which you still need to enquire about … All this will be interesting when the sun…

In the topic I asked them to close earlier today the experts said to not play with the settings of the shunt. So I didn’t. The battery was on 14.1V when I connected. Now it’s on 13.36V which is 100% if I listen to the SOC. Then what was that 14.1V in the beginning? 120%?:smile: But seriously…I don…

On a 24V system. Based on Norwegian prices. I’d use 2x2 with 2x SmartSolar 75/15. 1: Redundancy, if 1 charger fails you are not stranded 2: You can DIY, sort of legaly🙄 3: Unless you are stationary you will get shade on a 4x string. PV panels reach Voc max at sunrise so that is not an issue as…

I have a 12V system…with 280Ah LiTime lifepo4 battery.:wink: My system is 95% ready and installed and - mostly - working. But thinking on a little update to optimizing things to my RV.

Oki. I’ve done a reset on it it few hours ago and didn’t touch it yet.

" Tail current In VictronConnect see: Settings > Battery > Tail current. Some lithium battery chargers stop charging when the current drops below a set threshold. The tail current must be set higher in this case." I don’t understand what to do with this…

SmartShunt settings are wrong for LiFePo4 (charging V, discharge floor, peukert…). See documentation, particularly Lithium section: https://www.victronenergy.com/media/pg/SmartShunt/en/configuration.html#UUID-43af2c64-8f8f-f942-0603-283d02efa6aa

I had an installation on the roof of our wheelhouse with 6 panels in parallel. This may sound weird, (extra thick wiring) but on a ship it is rather unforseeable if one ore more panels may get in the shade, Same migt be the case with a camper. In a serial setup one of the panels could block half o…

… I’m totally with you on that when you look at this roof …

Is it really difficult here with a parallel arrangement …
The issue is achieving max Voltage as early as possible … so in series
