Surely you have just done the same thing and assumed something? Oh and Squirrel

I used the same kit, cables, power supply and voltages to balance the cells. I may have made an error along the way that went unnoticed by me but I can't be sure. I'm still convinced I had one duff cell from Senbury out of the 32 with the bloated cell but its my word against theirs and i cant...

TN-C-S is a combined N to PE at the point of supply plus PME along the supply line. As @SeaGal has stated you will require a separate Earth Electrode installed. the Sunsynk does have relay output to do this for you. Depending on what model/size Sunsynk you have, they have a full bypass mode so...

If its tripping the breaker/MCB then you have an over current situation, nothing to do with the datalogger, you have probably set your charge rate higher. What breaker size do you have installed?

@Chargery So another small revelation after reading the translated manual from the resources on here vs the manual I had 2. Cell voltage display is not accordance with actual cell voltage ---Check a) Check 9 pin balance wire connections are good and secure. --- Check b) Measure actual...

This is not true, Im coming up on six weeks when I ordered mine for air freight 7 day delivery, they eventually gave me a tracking number but the goods haven't even been collected. Don't buy in to their "it's in stock bollocks"

I had one of those isolators and it gave up spectacularly even under 1/4th of its rated amperage. They are junk. have a look around the back of the isolator.

Its my first outing with it, It cuts off on charge mode when the current drops to 10ma @3.65v , ive hooked it up to my network so its logging the charge curve to my NAS drive. so far its been blanacing for 6 hours and only dropped 160ma

I think its a fallacy having the fridge on a timer.

Thought id chime in here, I purchased the Seplos 16s BMS 100amp foor $125 after seeing a nice guy called Tony on here saying his worked great with the same inverter I have, it arrived yesterday, thought this would be the missing link between my current CAN compatible ME3000 storage inverter and...

Here you go, this is a shell script that I run from a Raspberry pi that pulls all the cell voltages, temps etc, could be made to write directly to influx to be read out in your dashboard, unzip the file, edit and change the TTY to your device and run ./seplos.sh 4201 not my work buy a ncie guy...

Glad its sorted out for you good sir. Happy new years to all.

This doesn't always work worldwide, I now have just over 22kWp of panels on my roof here in the UK, for the past 10 days its been almost dark, cloudy and generally shit weather wise. the most I have logged is 1.3kW being generated, just enough to run my home but doesn't charge my battery bank up...

Hi, thought id try out these active balancers people have been discussing. I have connected up the balance unit to a spare purposely unbalanced 16s 280ah LFP pack and it doesn't appear to be working at all, the run light comes on, on the connectors measure fine with a multi meter but it doesn't...

Firstly, thanks to all your recommendations. Secondly, I put the pack in to service last night, after the parallel balance at 3.65v My night load is quite high at 780w I woke up to see all the cells within 50mv of each other and an SOC of 42% on the bms and 44% on the inverter Id set my...

I guess if you are getting the max capacity out of your cells this way then stick with it. For me with the Sofar inverter and LA mode it was all over the place it doesnt work without the temp sensor connected in SLA mode and you have to disable the inverter logic. wit the Seplos in place it...

"Realtek USB to Ethernet connection" unplug that straight away, its probably too late but you will have potentially damaged the port on the BMS, its not ethernet! it just uses the RJ45 connection. As you even stated you didn't get a USB to RS485 adapter but you've plugged in an Ethernet to USB...

I have probably sold and deployed 120+ of these units in various different amp ratings and bar the diode issue/recall I have never seen a problem at all. The comms side of things works every time, I use this https://tinyurl.com/4fewc3x8 RS485 adapter, set the baud rate to 19200 n 8 1 and click...

Don't confuse A/C current draw at 120V with the DC draw at nominal 48v your readings are correct. As for your question, if you have16s4p all 280ah then you should have a 1120Ah pack in total or 53.7kWh pack capacity, either the cells aren't 280Ah, not wired correctly or they haven't got to full...

So I'm 3/4 through the install, things haven't gone exactly to plan so far. I had ordered and paid for the LG neon 2 panels but received Longi panels, although the Longi seem to have very good reviews and a better output. I had anticipated and specified one large inverter to fit alongside my...

Revelation time I just had a thought, as i'm powering the BMS from the battery pack itself, it also has the option to use an external DC power supply with a little toggle switch. although completely impractical for my use, ive run an extension cord outside to my battery box, pluged in a 12v...

Starlink is satellite based, I have it as my main connection here in the UK, it draws 90 watts under full load and give me around 300/350Mbps

They are uploading as I type this. Ill drop you a DM once done :)

How long is a piece of string answer. Cell condition second hand? Capacity? I.R? Use case for the customer, charge cycles, current demand, charge style and rate... list goes on.

I think you have misread my post completely, im not on a grid tie system or even feed in, this is stand alone system, its a hybrid inverter that feeds a totally separate non grid connected ring main for an out building. There's no sneaky theft by the utilities or dodgy smart meeters

The failry large elephant in the room, 3885mV single cell voltage for LFP?

HI Pete, I'm in the UK but much further south, near Cambridge , technically I'm in a slightly better location than you for being further south for PV production, My findings on my very large 22kWp system with 32kW of battery storage and an iBoost water heater, array 22 degrees from south. As...

In a nominal 48V pack i.e 16s, I disconnect the buss bar between cell 8 and 9 to create two lower voltage 24v packs giving a safer voltage to work with. then remove the cables to the inverter. Make sure the inverter is off first and no loads on the cells.

I'm working on a 3D printed enclosure for it as we speak, as soon as my replacement arrives this Wednesday (and hopefully works) I will let you know how it fits.

"Rated voltage 5.55A" :unsure:
