Thanks for the research. Some of my cells are in Mexico at my house and I am storing the rest for now in Tucson while I move to Ketchikan Alaska for 2 years...eventually, i will build them into a system in My Baja house...lol

Discharging temperature range: -28 °C to +50 °C / -18 °F to +122 °F Charging temperature range: -28 °C to +50 °C / -18 °F to +122 °F From your link... I was able to charge and discharge simultaneously but only by bypassing the bms. heading to Baja Manama so I haven't had more time to play with...

I put the battery back together today for further testing. I will try to contact Voltabox but I think their American branch may be closed down. I figure each module must have 11 cells in series to make 25 volts. My guess is that each module has it's own BMS that is tied together with the other...

I have not had time to work on it. The bms it came with shut down when I charged and discharged it at the same time. I may not be able to use the bms...

No, once I figure out the BMS wiring, I'm going to connect it to my All-in=One and my PV array and test the capacity through trial and terror...

I changed plans from using the 32 CATL LIFEP04 cells I bought in the group buy fiasco (now to be used at my house instead). I've been buying a lot of stuff on Ebay and Alieexpress using an app called social good which gives you 50% and 100% back in crypo for shopping through the app on those...

I got these cells from Michael in the group buy debacle. They arrived in much better shape than most of the groups orders. You can see my posts on the subject. 7 or 8 arrived with small dents and 1 with a medium dent. I paid $3825 for the cells and $306 for the Overkill 48V BMS's. I was putting...

I am building a vehicle based system with 2800 watts of solar (2 strings) to a MPP LVX6048 All in One with all loads being 120V for now. I have 32 CATL 271AH batteries that I plan to build 2 battery banks in parallel with their own Overkill BMS systems (see drawing). I wonder if this battery...

My last two boxes came in so here is the final summary: Ordered 34 grade A CATL 271AH with M8 studs, with busbars and hardware and including capacity testing and matching. Received 32 unmarked cells with no paperwork or labelling. All studs are M6 instead of M8. Received only 21 busbars and no...

I looked at some of them.

Hoping for the best but expecting the worst, I hid in the shadows of my driveway to waylay the UPS driver on a nice cool day at Furnace Creek (107 degrees). 6 of 8 boxes arrived today with a couple of them torn with visible batteries inside. The end result was 7 or 8 cells with minor dings plus...

The UPS truck is enroute to my house with 6 of 8 boxes of my batteries. Should I reject them if they look poorly packaged. What happens then?

Frustrating...

Generator needs to supply a 120/240v output. 2 hots, a neutral and ground.

From Michael's quote "free capacity testing and matching prior to shipping"

I intend to pick mine up at the first UPS location after arrival at the port. If I have the same supplier and crappy packaging, it might help to determine whether they are getting damaged during the UPS part of the journey. Even if the damage is happening during UPS transport, the fundament...

I have 34 CATL 271 cells en-route with a shipping label date of 6/29...expecting UPS to update in the next week or two. I will call UPS and ask them to hold them for me for pickup at the first location possible. Would that be LA? They are coming to Death Valley, CA...

This is the kind of diagram I would like to see for the LVX.

Of course in the video, the ohms stayed steady at 2 but in reality it was fluctuating... There is continuity in all three cases.

I did some testing on the unit by connecting temporary power from my house panel (bonded neutral) to the input of the LVX. There was no outut AC, PV, or battery connected. First the unit will not power up on only 120V input. You need 240/120...Gnd, L1, L2 and Neutral connections. GN shows the...

My meter reads 0 ohms between the output neutral terminal and ground with no external wiring connected. Someone could disconnect their output to eliminate any downstream ground-neutral connections (shouldn't be any) and turn power on. Then check for continuity between N and G output terminals...

The pictorial wiring diagram from their website does not show the same wiring as the manual I downloaded from Watts247. The terminal blocks in the manual and on my unit have G, L1, L2 and N connections for both input AC and output AC. The ground connections have continuity and also the output...

Did you connect the input to 240 plus a neutral or just 129v?

In your house system, if a ground fault occurs, fault current travels through the equipment ground (ground wire, typically) back to your service panel, then through the main bonding jumper to the neutral which allows the breaker to trip, No bonding jumper means no protection. The fault will...

Merging utility power with inverter can get complicated, Look at how Victron accomplishes power balancing on page 4...and they are not trying to simultaneously supply grid power and inverter power...https://www.solar-electric.com/lib/wind-sun/VE-Manual-Autotransformer-32A-100A.pdf The LVX is...

Your solar panels could exceed the nameplate power depending on your elevation. What is your elevation?

Is the fan the only load? If so, try adding a resistive load just in case the fan is not allowing it to exit low power mode...

It's on the large side:)

DEVA employee here. I live near Furnace Creek. I just replaced some weather station AGM batteries that lasted 5 years in a metal box in the sun at Stovepipe wells. It will reduce lifespan for sure but you should still get some decent life out of them. Putting them underneath is a good idea as...
