I have a Daly BMS 16S on three of my battery banks. All connected (via UART) with Solar Assistant. I recently top balanced some of the cells in my bank, before top balancing any of the cells I disconnected battery from main bus bar and removed the voltage sense ribbon cable from BMS. I did not...

Recently installed 2 SPF-3000TL-LVM-ES 48. Tested after installation and inverter and MPPT charging all worked fine. (No grid hookup so did not test utility charging) They worked for about a week in MPPT charging mode (inverter side was not turned on as did not have loads attached). After a...

Anyone know if Growatt SPF LVM can operate in parallel with SPF LVM-ES? I was hoping they might, as they are very similar models, with the ES version being capable of operating without battery. I have 2 SPF LVM operating in parallel and wanting to add a third and a friend has a ES version they...

A neighbor ran his 16S LiFePO4 EVE 280 battery bank down to zero while he was gone for an extended period. I am trying to see if it can be brought back to life. I have charged up some of the cells and then tested capacity, and measuring 250-280AH on various cells. Based on a single test it...

I have struggled to get stable communication between my Growatt SPF inverters and Solar Assistant running on Orange PI. It works at times but get frequent CRC errors. I have tried different cables, purchased cables with ferrite chokes, re routed cables, wrapped them in foil, etc. Sometime I can...

If the EG4 6548 is basically the same as the MPP 6548 (with a prettier enclosure) how does it achieve the 500V PV input verses 250V for the MPP? Are they using a different MPPT board? Just curious?

I have an existing 5KW grid connected PV system on my home; Growatt MIN 5000TL-X, 240 split phase. I am considering adding a 6KW Growatt SPF offgrid inverter/battery to provide backup power during power outages. The on grid and off grid inverters would both back feed breakers in the same main...

Got an email from Daly introducing a new BMS that sounds interesting. (See below). Pricing is ~$100 USD for 100A 16S BMS. Curious to hear if anyone has tried this out and their impressions... Now we are introducing our Newest Product: Home Storage BMS with 1A ACTIVA BALANCE function. * Be...

In the process of building a Salt Water Reverse Osmosis (SWRO) system and would like to power the high pressure pump directly from my 16s LiFePO4 battery bank to avoid taxing my inverters and gaining some system efficiency. 48VDC motors are available in the HP range I need but have not been...

I have a 100A Daly BMS and the SOC accumulator only decreases over time. The instantaneous current meter shows bi directional current flows but the SOC accumulator only goes down over time. I have another Daly BMS on identical parallel battery bank and the SOC accumulator works on that one...

Recently switched to Daly BMS. Worked fine for about 2 weeks and then disconnected loads; no currently flowing. Was able to communicate with BMS via the Daly Smart App and was showing zero cell volts, -40F temp and AFE chip error. Checked voltage at pins on voltage sensing cable and got normal...

The Daly BMS phone App works great for system monitoring and changing settings . Would love to be able to monitor or and change settings remotely when away. I have tried Solar Assistant, but it does not display individual cell voltages or provide BMS status or ability to change BMS settings...

I recently upgraded the firmware on my SPF 3000TL LVM 48P which resulted in total loss of MPPT solar charging. Prior to upgrading solar charging worked fine; PV icon would show on the display screen and PV would power loads and charge batteries. Afterward no PV icon on display; no charging...

Attempted to update my SPF 3000TL LVM 48 to newest firmware. Flash started, got part way through and then hung. After exiting flash program, Inverter display was on but inverter would not respond to power switch. I had to disconnect from battery to power down. Reconnect battery and inverter...

I recently order 3 Daly Smart BMS 100A 16S LiFePO from Daly store on Aliexpress. https://www.aliexpress.us/item/3256801617598581.html?spm=a2g0o.order_detail.0.0.6166f19c36qHiU&gatewayAdapt=glo2usa&_randl_shipto=US I also ordered 3 RS485 cables as I would like to monitor the BMS with Solar...

Switching to Daly BMS but the length stock wiring harness that comes with the BMS is to short for my battery bank. I have three 16S batteries, each with there own BMS so hoping there is a simpler way to extend the wiring harness other than soldering 51 extension wires (3 x 17 each harness). The...

I have 2 Growatt SPF 3000TL LVM (in parallel) connected to 3 280AH LiFePO4 battery banks (also in parallel) each with a separate Daly BMS. This set up is for an off grid vacation home where I am gone 1/2 the year. I have been using Growatt ShineServer cloud/web based monitoring, which has...

I needed qty 16 EVE 280K cells in a rush and my normal supplier was out of stock at their US warehouse. Searched on Alibaba and found Shenzhen Oneier Technology Co advertising Grade "A" Eve 280K cells with stock in US warehouse. I reached out and was contacted by Lucia Luo. She was responsive...

Below is the QR code for EVE 280K cell I recently received. Curious to hear from folks that have figured out the code if this is an A grade or B grade cell and when manufactured. The deeper question, for solar storage application with relatively low C rates and maintaining SOC between 30-90%...

I currently have a Chargery BMS, works great but if a low voltage condition occurs it disconnects the battery from the Growatt 3000 (note the Growatt is an all in one, which has just one set of cables connecting the inverter/charger to battery. If you open the connection between battery and...

All in one inverter/ MPPT chargers like Growatt, MPP Solar make for easy setup and installation but the question is how to best setup a BMS when using an All in One? Here's the problem. With All in Ones the Inverter and MPPT are combined in one unit and there is just one set of cables...

I have a system with 2 Growatt 3000 (operating in parallel) and Chargery BMS with separate charge and discharge relays (external 250A DC contactors). With this configuration the BMS opens the discharge relay on discharge related faults, and the charge relay on charge related faults. PROBLEM...

Ordered some replacement cells for my battery bank and the new EVE 280 cells I received have studs rather than treaded insert. Thinking I will add studs to my existing cells so all are the same. Can anyone point me to a good source for studs that work with the EVE treaded post (6mm) Thx

When designing a system with paralleled batteries, each with there own BMS, is best practice to size each individual BMS to handle the maximum possible system current or simply max system current divided by the number of paralleled batteries/BMS. Lets say for example you anticipate 200A max...

I have a 48V-560AH LiFePO4) battery bank (2-EVE 280 cells in parallel , 16 series) solar only charging and float set to 54.5. I notice that within 30 mins of sun going down and no load (other than tare loss of inverters ~75W) that the voltage drops from 54.5 down to 53.8 and then levels out. See...

No doubt a dump question but hoping someone can explain why on a common port BMS (Daly 16S 48V 100A) there are different current ratings for discharging (100A) vs charging (50A)? I can follow the logic for different current ratings on a separate 2 port BMS but on a common port why does the BMS...

Hoping someone can explain what is the difference is in Battery type USE vs USE2? What impact does it have on settings available and how the inverter perform? Which is better USE or USE2 when using a LiFePO4 battery bank (not a Growatt Battery) ?

According to the manual the low voltage cut off setting 22 (voltage that the inverter will stop discharging) is settable in a range of 42-48V which is on the low side for a LiFePO4 battery bank. (I would like to set mine at 51.5V) Has anyone figured out a work around for this? Much better to...

What would be the simplest method (for layman) to set up remote monitoring of a Daly BMS? It appears the Daly supports Bluetooth, UART, Canbus but not Wifi. Was hoping to be able to monitor my battery when away, and unfortunately don't have a background in building a communications method. How...

Revisiting an old post but curious to hear what folks recommend for a BMS (100A 16S) that facilitates easy, off the shelf remote (off site) monitoring? By easy I mean does not require building special hardware or software. Anything new out there?

A 48V-560AH LiFePO4 battery bank I built about 2 years ago suddenly has a low cell. Nothing physical apparent, connections all tight including the BMS voltage sense wires. System has worked flawlessly up until recently when it went offline because the BMS disconnected because of a low cell...

Any one know if there is an easy way to force a Chargery BMS to energize the external relay even though a parameter setting is out of range? I suspect a weak cell (or bad cell voltage lead connection) has triggered the Chargery to open the discharge relay (NO relay) disconnecting my inverters...

Installing a 1000W inverter in my pickup truck (12V-100A max)) which will connect to my trucks starting battery. I was intending on using #4AWG cable for both positive and negative conductors (about 20' run from batter to inverter location) but ran across an article indicating it would be...

I would like to fine tune my charging settings to maximize the cycle life of my LiFePO4 battery bank (2p16s 280AH cells). Solar is the only charging source. Following the recommendations on this forum I initially set bulk to 56.4V (3.53) and float to 54V (3.38). With those settings I...

In the summer months my off grid system (5.5kw PV; 32kwhr battery, 6kw inverter) has the capacity to produce more energy than my system consumes. On most days my batteries are fully charged by 11am and my PV MPPT charger (2- Growatt 3000 LVM) will start limiting energy harvest for the...
