Dave, "One cell will go high early and reach HVD before the MPPT has a chance to finish its

Here's what I ordered to load test, EbC‐A20 Battery capacity tester : https://www.ebay.com/itm/

As far as I can see the external potentiometer is not included with a new MeanWell so if you got one

Yeah that is way above my pay grade, that stuff is so small that I can barely even see it. (I'm

I do not know what you will be controlling with the EXT IO3. If is a Victron Battery Protect or a

Yes SBMS0 can handle that battery bank. It is in fact the same configuration that I have On Monday,

I have never seen that before. That half capacity cell will normally not be more than half the price,

Many thanks for the detailed reply and info. Yes, I was aware of the internal heat soak being the key

Ah, now I see you can't have a negative load current :) On Monday, December 22, 2025 at 12:59:06

Full sun today and also the shortest day of the year (technically the shortest is tomorrow but no

The cable requirement will be the same for positive and negative. If your panel is 15m from battery

You can also connect NTC thermistors 10K B3950 instead of 10kOhm resistors. The DMPPT450 without the

Thanks for the replies. The model I have is an MPB 1200-12. Yesterday I had the generator running and

Xavier, Your battery is fully discharged not just that one cell. The photo's you provided show a

Have you removed the red jumpers from your optoisolator board ? You mentioned that red LED is not ON

I took a few screenshots from my setup so you can compare. This is from today on my setup with 560Ah

So from the adapter project I learned, that you can also access the serial port by using /dev/serial/

Just letting you know, that I have added support for the serial Port / USB Connection. So you can

You do not need to set a max PVOUT current since most likely you are not using a dual PV array.

Yes you can have multiple EXT IOx set the same type. On Monday, September 29, 2025 at 12:37:17 AM UTC
