It is hard to tell what the real cause of the fire without the details of the installation and pictures before the fire.
It reminds me of this guy that claims the NEW generator caught on fire...
Since BB also found leaking cells in their stock (see the pictures in one of the post) in their own place in Chatsworth, CA.which is not in the hot desert. I also wonder if seth would get good response from BB if he did not post his issue on the video and on this forum since BB was trying to...
'trying to connect them in series and all hell breaks loose.' that does not make sense to me if you connect positive of one cell to the negative of the other cell to make series connection, but the other terminals of the two cells are not connected to anything to complete the circuit so there...
The good news is that I just received the four LISHEN 280Ah today, I ordered them on the Nov 3rd, they arrived on Dec 13th and sit in the customs for 13day, FedEx picked them up on the Dec 26th and delivered to me on the Dec 30th which is not bad at all. The bad news is that the bottom of the...
I plan to put insulation sheet between the cells when I wrap them up. With this result, it will be bad case for mobile application if cells are not separated with tough insulation, I would not trust the PVC wrapping either. So if you strap them tightly, make sure to add insulation sheet between...
I am still using my two batteries packs in parallel and keeping close eyes on them until I have the money to build my second 280Ah pack, so far no issue, I am charging and discharging about 3KWHr everyday...
+1. I have the exact same meter.
The probes are for Volt, Ohm, Diode, Continuity, and Capacitance test; the probes are not for measuring the current.
You will set the meter to DCA and then you use the 'ZERO' button to zero out the meter then put the clamp on one of the panel wire to see if it...
I just start getting into the Solar system, my power requirement is only about 200Whr.
I bought two used Sunpower 230W panels from local seller to play with first, the PIP-1012LV just arrived today. I am still waiting for the LiFePO4 90ah and DALY BMS to show up for me to build the battery pack...
I wish you stick to the old thread, I did ask in the old thread post #15 "Can you try the old inverter (the one in your picture in post #1) to see what happen?" but never see the reply, and now in this thread we found out you have the same problem using old inverter. It is hard to keep track...
Did you connect the SCC to the battery first? do that with no panel connected yet.
What Voltage does the display of the SCC show for the battery Voltage?
Mine is ATORCH 150W, when I first use I could not get to 20A using 10AWG 15", I was able to get to 20A after cutting the wire to 6" but I had to put the unit on a stand to the same height as the battery, it ran for about 5 minute at 20A before blowing up the MOSFET.
I replaced the MOSFET and...
So no gambling buying stuff from Amazon or Ebay?
Or buy from US company like this one?

I wonder why the QR codes are scratched off, I thought Big Battery would use brand new grade A batteries from REPT (as corrected by the notes in the video).
7:50 Time code.
According to Leoch:
Dear friends, The pre-production units for LEOCH have already been shipped to some credible reviewers, including William Prowse, HOBOTECH, Silver Cymbal Productions, EBPMAN Tech Reviews, and Maxx Powell. Once it's out on YouTube, we'll post it here and also in the Facebook...
I just finished the capacity test of the my 12V Battery pack, the result is 278Ah.
I stop the test when cell # 1 (damaged cell from shipping) reach 2.61V, the other three cells still show about 2.85V, the CellMeter 8 shows about 200mv difference at this point, they were about 13 ~ 15 mV during...
What is LRA (Lock Rotor Amp) of that freezer? The startup current of compressor can be from 3 ~ 7 times of running current.
"When I turn on the inverter, BEFORE plugging in any load, the battery voltage tested by multimeter, and also on the inverter display, reads normally about 13.6v. As soon...
Can you provide the waveform before the FW update?
per this thread: https://diysolarforum.com/threads/resolved-eg4-6500-and-6000-lights-flickering-firmware.54956/
What happened: An unauthorized minor component hardware change was made at the Voltronic factory on the standard 6500 and 6000w...
They need to put insulator between that metal stanoff and the PCB which has trace on the bottom side of the PCB, right now they are relying on that the PCB will not flex and make contact,.
They had this problem Growatt 5000ES so they lay out the PCB to insure that contact cannot be made, i...
That is switching power supply PCBA (PCB PS-2000QAC-4 Ver.2), made by LINGQI inverter company.
Are the two big boards also have LINGQI printed on the boards too?
It looks like C3 was exposed to over Voltage so it blew up.
What is the DC Voltage rating of that big Lytics cap?
Interesting reading from Sunpower. I was looking to learn about shading effect and bypass diode, I did not know about heating issue due to shading, I member one of the member shows the pictures of burnt up cell that melt the panel.
Reverse Bias and Bypass Diodes
When cells are put into reverse...
That is one of my main concern, removing just screw without removing the standoff or put insulation sheet under the PCB is not acceptable, the clearance space between PCB and standoff may be only 10mil (0.01"), it can easily have arc over in damp condition/contamination. i can easily put Scotch...
