Thanks for the reply. Sometimes a shot in the dark works. Cheers

Relay cont. Clicking on and off for pv charging, lcd shows the 110v on pv. Then clicks off and back to bat voltage on pv lcd.

I am having similar on spf 3000tl lvm. Lcd shows panel but no lines to indicate charging. Led charge light blinking, only voltage shown on lcd pv voltage is the battery voltage. Pv @ 110-113v tested from array down to breaker to unit. Shunt display shows several hundred watts in but in full sun...

with temp calc applied to voc.

Typical Growatt. By my calc should not exceed 130voc.

145.

Had Right hand fet failure, below transformers, mid unit vertical row. Magic smoke, etc.

Minus 20. Hawaii avg temp @ 72L 85H °F. Sorry for the late response and thank you. 3s3p to mndisco6 per mppt (x2)

My dual spf 3000tl lvm have a setting 22 for solar power balance which on those units run fine enabled. The spf 6000/8000 do not have said setting though.

I am having similar issues. Spf 8000 + 6000 2 lfp banks 280ah Both units (same system swapped units) at full charge or cv of 57.6v shut power for short bit (long enough to throw clocks to reset, lights out, etc) I assume it is the transfer time when shutting/ throttling array down to meet the...

What is your max utility charge current set to? If 10 amps then your 29.v or so charging would be around 300w.

A lot of us are in the same boat with these units.. Here is the thread about the problems and the issues it causes with neutral and grid.. Long but a must read.. I am still trying to figure/ settle on a solution as well. https://diysolarforum.com/threads/growatt-12k-passthrough.37359/

Blue sea and othe class t fuses also have a high AIC and offer ignition protected blocks.. Amperage 225A Maximum Voltage 125V DC Stud Size 190 3/8" Interrupt Capacity 20000A @ 125V DC Weight 0.30lb (0.14 kg)

I use the midnite mnedcrt 175 and 250s With AIC 50,000 @ 125VDC handled remotely in an enclosure and they are around 7".. not crazy huge... From their website: MidNite's breakers are rated to break the full rated load at the rated voltage repeatedly, with NO DAMAGE. Always use a properly sized...

Yeah I do see a lot of lfp banks "hidden" away but I rather enjoy seeing everything involved. It definitely is a conversation starter -even without the lights going. Mostly though people can't get over what all I run off of that bank and my system for its size.

Thanks!

Thanks?

Hello from Hawaii! Here is my small system that I put together about a year ago. Recently finished the lfp bank in the beginning of May. 8s- 280ah w/ 250 "smart" daly ( yes yes ugh.. a stepping stone) KG140F 400a 600v- shunt coulometer controlling a MNEDCRT breaker for ov/uv etc protections...

Well in my application the shunt/remote trip breaker is my battery's main disconnect as well one of serveral protection devices on my bank (fuses, etc..) . I use it rarely for this (manual- switch style shut down for upgrades/work) and hope it never has to be tripped by an event(remotely or...

I assume my fet bms would fry before the breaker is tripped due to the response time of the meter but my cells would live? I bought a kg140f on ali for around 50usd. Also spoke with the company and they are supposedly working on programming/ firmware update so as to control shunt/remote trip...

Ah got it. My shunt coulometer can handle 600v.

Have your batrium trip a mnedcrt and/ or mnepvrt. I have my shunt coulometer with multiple programmable protection values controlling these. If a sensed failure caused it to signal and trip the breakers I would want to be there to address the issue and fix it. So the inability for it to turn...

It also has usb.

Should have a circular bluetooth dongle for the daly smart app.

Thanks

It is a Growatt spf 3000tl lvm. With an ac push button breaker with no listed specs. It can surge 5s @ up to 6kw Has overload protection of: 5s@ 150% load 10s@ 110%- 150% load With programable restart en/disable after overload. It has honestly been a great unit. Just wanted to (and was wondering...

Right I am looking for something that will trip more on the actual rated load not 5-10x after long enough to well blow my inverter if it does not shut down the ac out properly in time.

Any ideas on which kind of breaker to use as ac main before subpanel (serving as my only breaker box) from inverter ac out? Can handle 30a continous out and 2x surge for 5s. I want to stay away from the max (or any surge) and I monitor/ know my home and system well. I just dont want the typical...

Thanks for the idea. I just went ahead and bought an external drive. Problems still remain though. For some reason I cannot get the software/ program to com with the charger? There are practically no directions for monitoring or computer setup. I have it unzipped, installed, and running but...

Thank you everyone and thanks again @BentleyJ for the help with this!

It or something that can will be used to trigger a mnedcrt (.1s pulse one time @ 24-30v ) remote trip breaker to battery bank and/ or pv after being signaled by my kg140f in the event of programmed protection being triggered by ov/under voltage, mppt failure, temp, ov current, etc instead of a...

I wish. The youtube video quality was crap.. I believe it says BatSpy REM Trip Module 18-75v in 24v out. Usually I can find just about anything with ease but this has been tricky.

I have been trying for days to put a name to this or source one with no luck. ? 18- 75v in 24v pulse out. Pulse out when power in cuts out. Anyone? Thanks

Aloha everyone, I have a fet (yes a daly "smart" 24v 250) based bms on my 8s lfp connected to my Growatt 24v spf3000lvm with a kg140f shunt monitor that has many programmable protection functions to control a no/nc (selectable) relay. I have a mnedc as my main battery breaker but have purchased...
