Zero load in worst case scenario for M II 8000 is rated at 29W. In winter I keep it in AES, which lowers it to 19W

We can revive this thread and see what they say: Victron Community Page. I thought the Multiplus II 8000 is heavy, I can't imagine the quattro 15k. 😅

If it is still of interest, I heard that updating the multiplus II 48/8000 to version 508 would make it work in parallel with another one of the same. I haven't yet gotten confirmation from anyone at Victron yet, but hoping to get it.

Here's a final video from a relevant series that does all this research for us! Andy is great: I think this sums it up well, but you can check out the other videos for a full journey related to the discussion here.

My main question was if not bringing the Lifepo4 cells to 3.65 V has a detrimental effect on them over time.

The balancing actually does work pretty well in my case as well, and it does start depending on how you program the BMS. Here is a screenshot of the battery after it went through a short cycle to 100% - it is autumn now - and the bms did some balancing.

Hello fellow solar enthusiasts! My system is working like a charm. I charge the pack of 16 Eve lf280k to 55.2V in absorption, and they are all fairly balanced. I've never seen the delta above 0.020 V. Each cell voltage never goes above 3.5, 99% of the time stays in the 3.45V area when fully...

Thank you all, I love a good discussion on this forum... almost like a pub evening, except we're missing the beer and burger. Summer's over here in the UK :ROFLMAO:, the rain came back and did a much better job than I did trying to reach those panels on the house.

Hi fellow solar enthusiasts! We had a high pollen ? period here in the UK and everything was covered in yellow dust. I knew about the pollen period, but had no idea it can significantly decrease production until I noticed the numbers being quite a bit lower than expected. I noticed in peak...

I'm not even 40 years old... :giggle:... so I'll need numbers. Yes, I've heard 4NM for the older model with welded studs, but haven't seen info on these types I have now.

Thank you everyone for their replies. It looks like I can use either bolts or studs, for bolts I'll have to be careful not to pierce the cells. Does anyone know the recommended torque to tighten these please? Thanks!

Hi, I've got a new series of lf280k, planning to add a second bank to my battery, however, these came with different terminals. The bolts are like in the pictures... Any reasons why I can't get proper bolts (with the head) to tighten the busbars in properly? Thank you

Thank you, everyone! Regarding solar and anything around it, there's no better place to get info. I'm glad I asked, it spares me extra expenses, as I already have the 1/4" x 1" pure copper bar. There won't be more than 300A traveling through it, so that's safe to use. Thanks again!

Hi! I've found various info on Google searches but wondering what would be the right way to size my busbar. For wires, I can look in the table of the providers for the wires I buy. They have an amp specification in accordance to their size. But with a bare copper tape / bar this information is...

Brilliant, thank you everyone so much. I'll be using the long bolts on the sides to mount them on a custom panel. I've already un-bolted the current mechanical lug and it looks like an m8 bolt fits there, so I can put a proper compression lug there.
