I am having problems getting the Seplos BMS to communicate with my PC via the standard RS485 protocol. This is a long story but basically I am on my second BMS ( after seplos admitted the first had a problem) following a successful warranty claim. Today I spent approximately 4 hours with the...

I have the above Inverter and BMS and am wondering whether my inverter actually has CANBUS communication as I have been having some problems getting it to communicate with the BMS. I have also read that many others have the same issue and it turns out that some early versions of this Growatt...

I have the above controller and PSU which I am going to use to top balance my 280ah 16s pack. This post is not about the process of top balancing but rather the Riden unit,. On the front panel of this unit there are three connection posts 1. Black negative post 2. Green battery charging...

I have a Spelos 48v 200A 16S BMS (see link below) and this BMS has three contact/ screw points on a bar strip (see the attached jpeg....BT B+ and P+) for connection of the battery negative (B+) and inverter side positive (P+). I have a few questions on the purpose and options with connection as...

I am in the process of sizing the breaker/ fuse between my Growatt SPF5000 TL HVM inverter and my 48v Lifepo4 280AH 16s battery box. The system will be initially set up as a UPS only but later I will add PV panels and then at a final stage (after I expand the property) another bank of...

I need some help on a breaker recommendation for a DC breaker between my battery and inverter. What I am after is a 150a 48/60v breaker that will take a 2/0awg cable. The lugs on a 2/0awg cable are big and I am having difficulty finding a good quality breaker that will both meet the 150a cutoff...

There are several posts on this forum discussing the idea of placing LiFePO4 batteries in a fridge to keep them cool in extreme climates, but has anyone actually done this? Excellent research in the attached post by jmcroy however I cant find a post where anyone has implemented this solution. I...

I would like to order some of these for a battery box -the cable pulls thru them from inside the box to outside. Does anyone know what they are called? Apologies for the poor pic.

There are plenty of cheap BMS's available at 100a but when looking at 100a+ and a 48v 16S BMS the options become more limited and very expensive (the Daly 300a is $300). And after reading quiet a bit I am confused on whether I need a high capacity BMS. I have a Growatt SFP5000TL HVM-P "all in...

Hello everyone. This is my first post and after doing lots of reading here I have a question. Should I configure one 48 volt pack or two 24 volt packs for my battery bank? My inverter is a 48v Growatt SPF5000TL HVMP and I have 16 Eve 3.2v 280ah Lifepo4 battery cells in transit. From what I have...
