Hi, I have a Victron SmartSolar 100/15 MPPT SCC connected to a Cerbo GX for remote control via VRM and VictronConnect. I am currently not using the relays on the Cerbo but I know they can be both connected to a manual mode (and one can be programmed which is not something I need right now)...

Thanks for taking a look at this! I didn't realize that while there is no load the battery voltage is actually a useful indicator of the SOC like with lead batteries. I got so used to not relying on it for LFP because it is (to my knowledge) too inaccurate while under load that it didn't cross...

status.png shows the charger is enabled and charging but in bulk state. settings.png shows the float should start at 13.5 V and absorption at 14.2 V. We see that the battery is not at that voltage, but it has no load and history-recent.png shows daily there is energy going into the battery but...

It is a 12 V battery and I have two 175 Wp 10 A solar panels hooked up to the SCC in series going to the SCC. The SCC is configured correctly for a 12 V LFP system so AFAIK it should be charging the battery with the correct algorithm. I am glad to hear the temperature is not a problem, I got the...

Hi, I have a miniature solar setup with a few panels, an SCC and a 206 Ah LFP battery. I used to have the setup power 24/7 lights in my shop but I disconnected the load some time back due to making changes to the shop lighting and I never got back to reconnecting it yet. I use a Victron SCC and...

Yeah I am definitely going to be looking at replacing the panels. The ones I have currently aren't able to top up the batteries as fast as I'd like. With the new spot and better panels I am positive I should see much better charge times as I will be able to both catch and convert more light.

The solar panel array will be land mounted and the line from it to the SCC input will be in a conduit and buried. The line from the SCC output to the battery is just wall mounted, the SCC and the batteries are in the same spot in the shed.

Good point about the MC4s! I think I will go with 10 AWG and accept the voltage loss. Maybe I will upgrade to higher Wp panels so that the output voltage of the array is higher and it is still high enough even after the loss. I will keep the temp adjustment in mind, thank you. I am using a 12 V...

So for my current 4 175 Wp panels with 18.3 V and 9.56 A (under load) connected in series, so 73.2 V and 9.56 A or 700 Wp if I ran a 70 m (230 ft) length of 10 AWG (6 mm2) copper cable I am looking at a 7.13 % voltage drop, so 67.98 V on the other end going to the SCC. That's 650 Wp. And if I...

Hi, I have a barn where I have run a small solar system I use to power its lights as well as the occasional power tool. There is a semi-insulated brick room in the barn so I can keep the electronics (solar charge controller, invertor, batteries with internal heaters) there. The barn has a south...

I didn't consider that, it is true that I can stop while still well within the safe levels and switch chargers once able to. I think I'll do that. Thanks!

You're right, I misinterpreted some of the earlier replies. Yeah, I think this is ultimately why I'll wait for the Victron wall charger to come before I do anything with the battery. The charger that I have on hand seems very odd to me. I still don't get why there is a range of voltage at the...

Yeah I left out some of the context from my original thread. My situation is that I'm not at my house where the solar system is now, but I did receive this battery and rather than just stare at it for a few weeks, I figured I might as well do the first two cycles as recommended by the...

I see. Still, I would have expected to see those values represented not as a range but as lines showing the voltages for the different states. I am attaching a picture of the label.

I found this weird, but the label on the charger says its output is 13.6-14.7 V / 1 A. I am confused why it would be a range. It is not an LFP charger so it does not state any specific voltages at the different charging stages like bulk and absorbtion.
