Maybe some remember my first Solar BMS. I had a successful Kickstarter campaign last year for that version and build about 100 units for those backers.

Now I'm in the middle of a new Kickstarter campaign and the first generation Solar BMS called SBMS4080 is powering my OffGrid house.
I already have two years of full type OffGrid with LiFePO4 and it works great for me.

Here is my house setup and as you see is a small installation with just 3x 240W PV panels and 24V 100Ah (2.5kWh) LiFePO4 battery
The 7 day energy production and consumption graph was done with the SBMS4080 so you can see how much energy I use and produce.
I use around 60 to 90kWh/month depending on month that is enough for me since most of my loads are high energy efficient.
Since PV panels are so inexpensive the heating will also be done 100% with solar electric in the near future no battery on that part just PV about 12x more than now and resistive heaters embedded in the concrete floor that will act as a thermal storage able to store 100kWh at 10C delta (the concrete floor is thermally isolated from outside and has about 14 cubic meter volume).
     


 


Here is a 3D render of how the new solar BMS will look like you can find more info on my webpage http://electrodacus.com or on Kickstarter page http://electrodacus.com/k/
The new SBMS100 can support up to 3kW of solar PV and a 3kW Load with 24V battery so 120A but there are many other improvements with this new version.
