"unless there is high resistance in your wiring such as poor connection" Thanks Bud, you are the BEST! It was a bad loose crimp on the connector. I wouldn't never thought a cable would be bad since I bought the cable "professional" made. I put in a new connector today and it boots up. Going...

If I purchase an Ampere Time 24V 100Ah LiFePO4 battery (to rule things out), would it be okay to connect this battery with the 24V LiFePO4 Powerwall from bigbattery (they advertised 3KW, so 125Ah) via bus bar? I was told it is bad to mix brands of batteries.

So it also shows 26.5V dc at the lamps wires? Yes What is shutdown mode? Yes, I used the clamp on meter. Connected to LV2424, turning it on. Current is at 0.07A, 4.9V (this dropped from last measurement)

Connected two 12V car head lamps in series, 26.5V pulls around 5 amps.

BMS cable looks ok, multimeter reads 26.5V at the battery

I will double check the BMS connections. I do not have a battery charger. How can I test with the 12V car head lamps? Is this something I can get from wal-mart or autozone?

First my simple set up, One LV2424 connected to four 24V bigbattery connected in parallel, connect to solar input and grid input and output. I have been working at this issue for over 2 month now, I thought it was a bad inverter, now I am not so sure. This setup has been running fine for over...

@ohseedee , You might be over voltage your lv2424, at least that is the case with mine. Try connect your solar panels in parallel configuration.

Any updates on your findings, I am getting similar results.

Anyone got LV2424 to work wit his script? I got an invalid byte response error.

Assuming this is all set up and good to go, how would you incorporate jblance's mpp-solar script into grapha? https://github.com/jblance/mpp-solar

My comments followed by ### for your how to document. select Raspian minmal install only - this is key on the Pi Zero to save precious resources. ###I would say Raspian minmal install only without the desktop version ======================= after install and reboot login at the console as...

when running # ./powerMeter.py, got an error no module named 'minimalmodbus'

Maybe we should start another thread topic instead of hijacking this one?

I didn't get any data display on grapha.

stuck on step 182.

I will start going though it. Would this work with the jbalance's mpp solar graph? https://github.com/jblance

@BarkingSpider , my parts are in. Can this co-exist with the mpp-solar monitoring(the one on github) as well?

I will be using a pi 3b or 3b+.

I already have the pi, the module will be here on Saturday. Looking forward to your script, Joe. :) I also have an Eyedro, so I can compare the results.

Would this work on MPP Solar LV2424? If so, I just need to get the pi set up and a usb to serial adapters? Have you considered using prometheus/graphna/docker and package them into a container?

I am interested in this. Can you provide your python script somewhere like in a git repo?

Just got a Bluetti EB150. When plug in an outlet tester, all 3 lights came up. This happens on both AC plugs. I have never seem an outlet tester display all 3 lights. What does that even mean? Can anyone else confirm they have the same issue?
