Monitor progress for the lithium battery pack
Using the lithium battery pack means monitoring the cell voltages. My current voltage monitor is 8S. This involves a lot of taking out and putting back and pulling and moving. There’s gotta be another way.
First test of the lithium 12s monitor. Found one!

On with the show: Numbers
After 27 days I have sent 112kw of solar power to the batteries. I have sent 94kw of solar power to my inverter. And I have done some very bad math.
99 kws sent from the batteries to the inverter.

An adventure with John
John is my neighbor. I call him the rocket scientist. He worked in Canada’s rocketry program. Back in the day.
The beasties. One lurking in the background. The other taking front and center.
Recently I had a nice adventure with John. We tried charging the “bad battery.”

I remember research right?
I’ve done a lot of research on this lithium topic. A lot. And after awhile, well, some of it starts to blur together.
Pretty much as expected. The battery is at 3.83. Now with the cell log we can see thousandth of a volt variations in cells.
I saw a guy putting a cell log 8 into his Chevy Volt battery plug and getting live results from his battery. Voltage checks down to the .00X of a volt. How cool is that?

Canada Day is officially Christmas Day for me
Woke up at 5. Yup. 5 hrs of sleep and I’m getting dressed and running out through the cold morning dew to the solar shed. Time to check the first night of lithium battery goodness.
47.6. That’s the voltage of my battery pack after running over night.
A picture of concentration as I begin wiring up the batteries.
You would think I got enough of all this last night. But nope.

And I am too
In celebration of Canada Day the lead is out and the lithium is in. Canada’s first
diy Chevy Volt solar ESS is live.

The new battery box
The new battery box is under construction.
The battery box is prepped.
Keeping with the recycled theme. The box is built from the pallet the battery pack came on. That and some off cuts of plywood from another project. Sweet.
So a quick checklist:

Will flames erupt?
Testing of the charge / discharge performance begins.
Ammeter install complete. Time to monitor some discharge loads. Movie night it is. Note that the idle current of 11.9 w is a combined inverter and TV “off” load. The inverter is measuring at over 10 w idle.
Added: Victron 48-1200 inverter. Would have preferred a slightly larger/parallel design. But this will suit for a year or two.
Cheap chinese ammeter/voltmeter.
Hooked up the TV for a load. And watched a movie. Perfect testing conditions.
