if you're in "/opt/victronenergy/dbus-btbattery" directory you type "nano service/run" replace 70:3e:97:08:00:62 with your bt address hold ctrl + o, then hit enter to save type ./installservice.sh then type reboot

Interesting. So it may not care what the AC frequency is. Wonder if you could use one of these simple HF converters? https://www.amazon.com/dp/B0B6Q7L3TF/ref=twister_B0BL425KTV?_encoding=UTF8&th=1 It's 20khz instead of 60hz, but if all the air conditioner unit is doing is rectifying then seems...

LOL, check this out. TimeUSB battery with LiTime silkscreened on the BMS

Yes, Redodo, LiTime, and PowerQueen MINI's all have the compression plates. They all have the same guts, case, BMS, etc..

I would try to get that replaced from PQ. The manual states charging voltage 14.4 +/- 0.2 So if it will not charge to at least 14.2v after giving it some time to balance I'd ask for a replacement.

Here's the cells from the Mini batteries. 4 cell group = 100Ah

You're welcome, glad you like them :) On the max load, if you know to keep it under 130A you're fine. You might want to consider as your battery bank drains, and you get close to your low voltage cutoff on your inverter, usually around 10.5v you'll be pulling more current to keep up with the...

Cool little system! Only thing I would say is your 2000w inverter will be a little more power hungry (when loaded heavy) than your system will be able to provide.

From REPT they call the new process to achieve this capacity Wending. They sent me some for testing, here's the result: https://www.prnewswire.com/news-releases/rept-battero-and-powin-team-up-with-320ah-wending-energy-battery-for-8-4gwh-indonesian-cell-procurement-project-301926331.html Also...

I'm hoping to update my tracker with bi-facials soon. I'll for sure make a video.

I agree buying more panels can be cheaper/easier. But space, if you don't have the space for more panels a tracker is a viable option. And also consider bi-facial on a tracker. I need to try this

Yeah, the BT hardware (and/or kernel driver) in the RPi is flaky, it will hard lock occasionally, and the only way to recover is to reboot.

I've used a lot of the Epever 20a, and 30a in remote IOT applications. To this day they are all running, never had a problem. Now that being said I had a 60a Epever for my own personal use, it died in 3 months of use. Never got a response back from Epever. I've since switched mostly to...

Yeah, I haven't found the time to continue work on it ATM. I think the Louisvdw repo now has bluetooth, so you might try that. BTW if anyone is interested in my repo I added a Virtual battery driver so you can series multiple batteries, and show up as one. I have two 12v batteries in my garage...

That's pretty nice. I have not heard from LVGOO yet, maybe I can email them. Thanks

I suspect these brands are just that, a brand. Seems there's a single factory that churns all these out, and the brands can choose the models the factory offers to slap their name on, and market it. Just speculation on my behalf, but there is so much in common from the actual components, the...

FWIW I find the exact same components in most of these manufactures. I've even found a BMS that is silk screened "Li Time" in a Timeusb battery. Have a look

They sure did copy the styling off Victron. But yeah, it's not compatible with any Victron communications. If I could find time, I considered writing a Venus OS dbus driver.

Have you tried to power cycle your Cerbo GX? I sometimes have to do a full power cycle on mine.

Also make sure you're wired like this

Based on the voltages, both batteries look to be charged. Looks like the SOC tracking/calculation is not great. This can happen if you have small loads drawing power, and it's exacerbated with multiple batteries in parallel since the small loads are even smaller when you split that between...

Sweet!

I just reviewed the PowerUrus 12v 100ah. It's on Amazon for $400 now

I remember that video. Did you seal it back up? Seems like it might be ok if it's sealed preventing the electrolyte from drying up. But yeah, I'd be afraid to use that indoors man ?

Anytime (y) :)

See if you can get them to send you the source code for the firmware :). I know that sounds far fetched, but I have gotten manufactures to send firmware source.

Sweet! I can't tell, are you switching PV input from the MPPT to the Micro Inverter? I have a bunch of Enphase IQ7+ Micro, that I plan to feed DC from my batteries to dump into my home. I'll setup something to monitor my incoming grid so that I don't export.

They will have a 280ah complete kit with REPT Cells for $999 soon.

I use cement backer board https://www.homedepot.com/p/James-Hardie-HardieBacker-0-25-in-x-3-ft-x-5-ft-Cement-Backerboard-220022/100183556 you can use this on top of plywood or OSB.

Dang it! :LOL:

If you want some cheap wire you can get at home improvement stores I've use 12awg landscaping lighting wire https://www.homedepot.com/p/Cerrowire-100-ft-12-2-Black-Stranded-Low-Voltage-Landscape-Lighting-Wire-241-1602C/202206449

@HighTechLab Very smart move to be proactive, rather than wait for grievances to pile up!

I've already sent it back. MPPT's that can start with PV voltage absent battery have an auxiliary DC/DC converter (separate from the main MPPT DC/DC section) This converter takes the high PV voltage down to 3.3v, or 5v to run the micro-controller that runs the main DC/DC, and the MPPT...

It may be a fine unit, I dunno. If you buy one ignore the sticker that says 100vdc, and section in the manual that says 80vdc. DO NOT EXCEED 75v VOC Here's the video:

Yeah, fried the second one. I would stay far away from 75v to be safe. Video coming soon.
