Hi All,
Some of you may know me from an older post where I talked about my energy efficient small offgrid house where I live now.
I made the decision to use Lithium iron phosphate (LiFePO4) battery for energy storage since it is the most cost effective solution for energy storage.
There was a problem that needed to be solved and that was to build a solar charge controller able to charge and monitor this type of battery (and any other Lithium since is fully programmable) since still a large majority use the old and expensive Lead Acid.
The solar BMS (Battery Management System) charger is now in beta stage and decided to make this Open Source and available on Kickstarter for those that need something like this.
Here is a
3D render of how the final solar BMS will look like there are some minor changes from the beta most significant the 6 capacitive buttons instead of the capacitive scroll wheel and 3 buttons.
And here is a link to the
Kickstarter project page for more info.
