I’ve had this inverter for around 4 years now. Took me a while to dial everything in as I built my battery myself, but it has mostly powered our 240V water well for all of that time. However about a year ago, it started randomly tripping off with an output out of range fault. It tends to...

Agree that a set up where the BMS would also cut off the solar input would have saved my Growatt from it’s own limitations. My system is running nicely now. Going on 3 months of uninterrupted ops! What works for me is staying well away from the min and max voltages for the 48V battery. That...

It’s an add on that is basically a battery level meter and a button that will short the two pins needed to turn it on.

I just dragged a wire across the pins where the light box plugs in. Don’t actually know which two it is. I ordered a light board but I have not even installed it since my system has been running non stop for 2 months or so.

Way late on a response but here is an update on my Growatt SPF6000TDVM. The system is up and running and I've had 3 blissful weeks of continuous operation finally. The Growatt is paired with a DIY 48V 16S 120 Ahr LFP battery pack operating with a 150Ahr Daly Smart BMS and a 2 kW solar array. I...

So I’ve been through all 20 pages on this thread and just about all others related to the Daly Smart BMS. I have a 16S 150A unit on a 48V 120Ahr LFP battery module. I use the iPhone Bluetooth app to monitor and tweak parameters. Lots of fun getting all to work over the last 3 weekends! Here is...

Hey Schovie, where did you purchase the light board from.

I had 2 bad cells out of a lot of 17 I purchased on Alibaba. Separate story about the poor quality control (and also bait and switch as they did not ship the Shenzhen Basen cells on the contract and instead shipped Higee cells). But right now I need one decent cell to get my 48 V pack back up...

RCinFLA That’s exactly where I’m headed. Bought an 80V 5-A power supply and I’m going to charge very slowly as I don’t want t disassemble the pack. And you are right on. The problem with the BMS is only that it can’t keep up when the voltage goes exponential on the cells that “top off” first...

I am new to this but I am experiencing exactly why you need to top balance at least with LFP. Similar to Airtime, my 16 120 Ahr LFPs arrived at about 50% SOC and all within 4-5 mV. Built a 16S pack with a Daly Smart BMS. Hooked all up to my 6kW Growatt SPF600TDVM Hybrid inverter, and all was...

Hey Damian. I’m sorta up and running. Not hearing that humming noise you mentioned When the charge controller is operating. I do have a high battery voltage fault I don’t understaNd as the battery is sitting at 53V (multi meter, shunt, and Growwatt all say the same). Any idea what is causing my...

First - I have to believe there are thousands of these BMS out on the market and I'm really surprised how poor the user documentation (in English) is from the Daly. What I take from this is the US is way behind the rest of the world and we are just not a big enough market for them to pay...

Installed on a brand new 48V 120 A-hr LFP battery module. So I just can’t get this thing to initialize. I verified the balance wires were hooked up in the correct order (voltage increases 3.27 V in order), NTC connected, and I’ve short B- to P- a dozen times. I actually ordered 2 just in case...

I’d be interested if folks have identified any repurposed existing containers that work great for enclosing a DIY 48 V LFP battery module? I’ve got 16 120A-hr prismatic cells on the way from Alibaba. Each cell is 1.9” (W) x 6.9” (L) x 6.7” (H). An 8x2 configuration would be approximately a...

Hey Damian. Not quite there yet. My 16 120 A-hr LFP cells don’t arrive from China till the end of this week. Can’t say for sure if you have a problem, but I have read several different sources that note these units are pretty noisy. Let me know if you figure something out. With my work...

Short update. Confirmed the Growatt SPF6000TDVM is indeed true split phase and they are the OEM. 2kW solar panels purchased, inverter installed, 17 Basen 120 A-hr LFP prismatic cells on a boat between US and China, Daly 180 A-hr BMS (Wfi module included) arrived, and about 2/3rds of the AC...

So here’s what I learned. The Growatt SPF6000TDVM Is identical to the Sigineer M6000L-48SP. Identical manuals except the Growatt has their logo on the manual. And Growatt pointed me to the unit information on their website. So one is just a re-label of the other. Still need to confirm both...

I hear you and am cautious. It is perplexing that the LF model does not show up on the Growatt website. The eBay seller I will say has a very high rating and has been active for years. Will do the due diligence before spending my money! Will see what Growatt says and report back.

Hey. I’m looking at the LF series also. There is essentially no information out on this series except for a brochure and postings of units for sale on eBay. I have corresponded with the seller and he affirms the LF series is true split phase. It does nor suffer from the poor surge performance...
