dionvdberg Posted April 30, 2022 Posted April 30, 2022 (edited) Good day all, moving this topic from General to Solar... So I have the following: 3kv Axpert clone 24v 4x canadian solar 350watt panels Victron bmv-712 Victron battery balancer Raspberry pi running icc software Forget the batteries, I’ve gone through 4 of them because of wrong settings or float bug issues, all was agm batteries. So I’m looking at getting a pylontech, but the only 24v option is the up2500. Is this a good option, and then where do I start with the correct settings because of the float bug? I only need around 600w backup for max 4 hours. So, what is the best way to put all this together, or should I scrap the axpert clone and go 48v? If I use a pylontech, should I remove the Victron BMV? This is my Inverter - https://www.fullcirclesolar.co.za/product/3kva-vp-3000w-unit-vat-incl-copy/ Any advice welcome, Thanks!

If your load is over 600W they will come short. The BMV can be handy to have but the battery balancer will not be of any use. Sorry to hear of the wrong setting on the AGM's. Quote
dionvdberg Posted May 2, 2022 Author Posted May 2, 2022 (edited) Thanks for the info! Yeah according to everything I've read, the settings was correct, but I have a suspicion they were chronically undercharged (Float bug maybe?), both sets lasted me just over a year.. So I'm just trying to avoid losing a very expensive Lithium also.. Cheers Dion Edited May 2, 2022 by dionvdberg Quote
