Thank you in advance!
Float according to the MPP LV6048 screen of 54.6 was netting 3.2 at the cells, seems too low. For a few cloudy days, the inverter shutoff at 48v about 3am.
This BMS spec sheet (vendor finally sent one) show
balance starting at 3.5v
overvolt at 3.75
overdischarge at 2.2v...
Gottcha, thanks for the info. I'm having a ?BMS? Battery imbalance issue, I'll post it separately tomorrow with some specs. Im regretting not checking the BMS was smart to make the battery easier to monitor.. live and learn.
Thank you. I thought 57v and 58v seemed unreasonably high. Maybe the Big Battery units function better bouncing off the limiter or internally defuel the voltage?
Hello. Relatively new to The forum but not necessarily new to solar, just LFP batteries. I've gone through many of Will's YouTube videos, and I found a few disparities on recommended charging profiles and wanted to set the record straight.

C4 (bulk) 58v

What voltage should be placed in block K10? Battery voltage of 48, or inverter split phase combined 240? The figures vary wildly with changes. I'll post everything once that's settled.
I'll heed to the experience. It does seem wasteful, but I understand the logic. I was looking at it as needing larger inverter etc, but it's more of a usage levelling/maximization it seems, level overall throughout the day with a smaller inverter and more panels.. if even not all are fully...
I did find a couple of the SIs for what you expected on ebay. I figured the lower price meant they were knock offs. Good to know they may be genuine. Have you had any units fail? I've done a bunch of desktop PC repair in my day. Stocking a spare PCB and swapping one in, I'm fine with. I...
Gottcha to links. Nothing commission based here. Uhhhhhh. Math. More math lol. Ok, now I'll have to go back to the spreadhseet, at least there are no letters in this math.
Helpful, no. But insightful 🍿.
As with all things, just trying to get a feel for 'normal and acceptable' to make every dollar spent within my budget to live it's best life until it goes up in smoke on the way out the door.
I haven't heard of using motorcycle crates as suggested, that would be an awesome setup. Definitely want to build a DIY solar tracker. I know more panels will solve the loss, though using something at 60% contradicts my Ryobi and Harbor Freight mindset.. throttle down lol. I'll need to build...
As titled, I fell in love with paper-specs of the below inverter. Then I saw a post here where multiple users have seen a 155w standby draw.
No idea why that's in bold, sorry! Lol
My ground array will have 10 acres to play in, so size is of no concern. Would a draw like this realistically...
I left that one. I've watched a bunch of videos by Matt Risinger and living in europe for 8 years, the passivhouse (spelling varies by country), I'm sold on 2x6s, spray foam in cavities and 4" thick exterior foam. My budget absolutely won't cover spray foam, but seeing houses under...
I was thinking the same. Definitely worth a check though. At the very least it should be considered a property upgrade to qualify for the 27.5yr spread. Most things are a 1-for-1 replacement, this is more like a new feature and being attached to the dwelling does add value unlike a power pole...
