    BMS charge double check please

    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...

    Lifepo4 charge discrepancy.

    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.

    Lifepo4 charge discrepancy.

    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?

    Lifepo4 charge discrepancy.

    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. YouTube MPP inverter video 1: C4 (bulk) 58v Fl4 (float)...

    Reconsidering SungoldPower 12k

    Reporting the audit. Question on block K10, it says voltage input. Should it be 48v for the battery, or 240v split from the inverter?

    Well, it was as bad as expected

    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...

    Reconsidering SungoldPower 12k

    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...

    Reconsidering SungoldPower 12k

    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.

    Reconsidering SungoldPower 12k

    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.

    Well, it was as bad as expected

    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...

    Reconsidering SungoldPower 12k

    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...

    Well, it was as bad as expected

    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...

    "Hatley has been arrested on 48 occasions since 1971". LOL. That's impressive. In a bad way, but impressive.

    Well, it was as bad as expected

    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...
