I wanted to share my experience with my battery bank in the hope that others might to.
I started out with two US2000B PylonTechs but then quickly added two more. I later added a US3000 when I decided to venture further to the dark side and be less reliant on eskom.
So far my batteries have done in the region of 700 cycles, mostly down to 30% state of charge daily and all 5 batteries are still showing a state of health of 100%.
I suspect the secret to their good health is that I charge the batteries with all they can take early in the morning to keep the temperatures down and I have limited the draw on the batteries to 1000W after sunset, the balance coming from the grid if its available.
I have been very happy with the PylonTechs over the four years I have had them and I have recommended them to anyone asking for advice. I would gladly buy them again without hesitation.
Here are my stats this morning which some might find interesting. The highest cell difference between any of the batteries in the bank is 5mV and its interesting to see how the BMS shares the loads between the batteries.
The temps are a bit high but the bank is stored in my garage and I try to keep it cool as far as possible.
This is a typical sunny day with my home automation running the show:
And here are the stats for my bank from my Home Assistant showing a 24 hour period with minimum and maximum values
Anyone care to share their data? I am very interested to see how the data compares on other installations?
