I’ve read/heard other have issues after doing updates on JK BMS’s but other devices, inverters as well. I would assume you could skip doing any updates at all to maybe avoid issues if all is well? I’ve had issues with my main house inverters after doing updates. Once the issues were resolved...

I ordered my first JK 4s w/1A balancer for small 12v project to give lights and power for a chicken coop. Finally got it installed and running Friday. So far so good, no issues yet. No problem connecting or setting up. However YT videos are the only way to learn settings, installation etc that I...

Thanks for the info. I watched several of Andy’s videos from Off Grid Garage as well. Seems to work well if you can control them to work only when needed or at certain voltage levels etc.

Good deal. I assume it can only balance one cell at a time. Transferring from high cell to low cell. My assumption is that all active balancers do that? I haven’t done extensive research on balancers or BMS’s with active balancers.

Good to hear that JK have worked out the issues discussed here in. I’ve read this thread, as I just purchased a JK for a small 4s 12v setup to operate items for a shed. I’m curious as to the active balancer feature. Even if you are NOT charge/discharging and batteries are at rest, will the...

I'm glad I'm not the only one here that watches Ben's YT channel (and others) to keep an eye on the suns activity. I really enjoy Ben's channel. I'm amazed at the people that have no idea what could happen and have that "look" when I talk about CME's.

Sorry, I have not replied sooner. I saw your message the other day. I got very busy and just forgot about it. I apologize greatly. I still have one of these if you want it. Where are you located? Inside the US, lower 48? Total would be $25 and $8.50 shipping: Total $33.50. What’s your PayPal?

Which box and where did you find it? What batteries? I’ve seen a similar charge controller on Amazon.

Great name!! BINFORD!! Used to like that show!! Nice set up!!

Trust me, I don’t want to share the thoughts I had, when I learned that…

That, I do not know?

A factory reset will reset KWh to 0. If you know the passcode.

I do not know what type or name brand it is. I’m not sure if those lugs were taped originally? I recently upgraded from the older 12 K models to the newer 12 K models. So when Scott sent his electrician out to do the swap, he is the one that put tape around the lugs. Not really sure why he did that.

Are you referencing something like this...

Shipment arrived today in good condition, cells all look good, flat, nice welds and all 20 metered at 3.296. Very pleased with this shipment from Amy @ Shenzen!

I’ve done one previous order with Amy, very pleased with my original order. Pleased so much in fact, I’ve got 20 more cells that should be arriving tomorrow (Tuesday). I can post pictures and impressions of the shipment when it arrives.

Very nice, clean, awesome setup!!! Great ideas and innovative!

I think you’re referring to the red wire going to power Batrium. All others are fused. I realized I missed fusing that one when we swapped inverters recently. However, with the issues I’ve had, plus work/life, I’ve not had a chance to fix. But believe me, it’s something I want to address. I even...

I will look later this afternoon. Edit: I looked at pictures on my phone, Same boards, not like updated MPPT boards.

No, never had time to do that. However it seemed fine until fans kicked on. RMA’d unit as of today. Less than 30 days old.

Nothing has helped. Even swapped out new MCU board.

Good to hear from you. I text you a few times with no replies. You outta come visit and check things out here, should come visit. Reach out if you want. So far 40 amps X 2 = 80 amps, has been sufficient to charge back to 3.35/6 v per cell each day. 3.35/6 Vpc, 53.9/54 volts is about 90%, that’s...

Exactly. In my garage, I have an original 1953/4 GE refrigerator still operating as it was sold, not refurbished. In the kitchen, an LG inverter fridge (25 cu/ft) that uses 562-kWh’s per year. How long will it last?

We built new so we had the advantage to plan this out. 2x6 exterior walls with spray foam insulation. Encapsulated our crawl space which regulates temperature and humidity. However dehumidifier does use energy but it is on a timer to operate 9am to 5pm when PV is likely. Crawl space stays...

Just fyi: Firmware update just finished and now says MCU Vers: 6224. Last update was Wednesday, (5-days ago) and it was 6222.

Thanks the good info and suggestions. That’s why I enjoy reading or posting here. Currently getting latest firmware/comms/mcu pushed again even though they’re on latest version. Since the factory reset did not help, we’ll see what this does. If issues persist, then see what SolArk suggests on...

Yes, however why would fans coming on cause PV to drop? The unit should work as designed. The other unit works even when fans come on. Update: Just performed a factory reset to see if helps and it did not.

It’s my understanding from SolArk that the 100 amp limit is per inverter. (200 amps total) Wednesday morning, when talking to tech support, the tech confirmed this, but, it may be worth a try to raise it and see. I did pull Batrium comms, with SolArk on its own, I still got the yellow warning...

Both are: Comm: 143f-1724 Mcu Ver: 6222 Update was done Wednesday. I saw another post here where SolArk leaves out 12K on the settings screen. Ditto for mine.

Issues are with one of the brand new units. (Installed Tuesday 10/17) Old units are in the box on a shelf currently. Latest firmware was done the day after they were installed. Both new units are on same firmware.

@HighTechLab have you seen this before or have thoughts on this?

Here’s a video of the glitch when cooling fans kick on. Watch solar drop out and battery charge turns to discharge for a bit. It recovers but shouldn’t do this when fans kick on. With this unit being the current number one, it draws down number two. When the other unit was number one, and this...

Yes. Old settings basically the same. I screenshot all screens before the swap. However, gen charge is now on grid input, recommend by SA in an off grid setup. Replaced because I had early models with “green” boards as I was told. Certain small electric items (hand held router, electric...
