Off grid solar is, luckily, improving rapidly.
I started my build in 2010. In my area there were no good resources so I had to head to the internet and hack away on my own. I made a few minor mistakes, but mostly my 1kw system has performed above, way above, expectations. I have most of the amenities of modern life … I just can’t use them all at once or whenever I feel like. Luckily I don’t need air conditioning when the weather is cloudy. And if I have to wait for a sunny day to do laundry … well I’m drying my clothes on a line anyway.
These posts will document some of my trials and tribulations. I try to keep it light, hope you enjoy.
First year with lithium and the bird is still on the wire
Well, I’m jumping the gun on my one year lithium report,
but I have to say everything has gone very well
no cell drift. None. Zip. Zero.
efficiency far surpassing expectations
no maintenance other than monitoring

It was a lot of research and study getting the solution worked out. However, the work has paid off. Thanks to all those on the web and elsewhere who helped me with this. A couple of forums; ecorenovator and endless-sphere in particular. Peace and happiness to all.
If anyone tells you to buy lead acid as a battery solution for off grid living. Run, don’t walk, away. Lithium rules!
Just received my new inverter. A CNBOU 3000. Look, it has a new display showing the voltage and the amps out. I haven’t got a fully charged battery to run the burn in and test the various idle draw claims. But looks good with the nifty display, no?
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.
