My Energy Storage System - DIY ESS - has been running with Solar for 3 Years now and saved me 800 EUR

On July 7, 2016, my home made Energy Storage System, named DIY ESS, has been running fine for 3 full years :)

Link from July 7, 2013 :

After several months of building and testing it back in 2012 & 2013, I finally had my Solar panels connected to a working SMA inverter and I have been storing my Surplus Solar Enegry ever since ...
(Solar panels install had been done several before that

During these last 3 years I had no breakdown what so ever, and absolutely no LiFePO4 Battery pack problem using it 24/7 (8 CALB CA180FI prismatic cells)

Today, few days after, it shows that I saved 577 EUR but you have to add 220 EUR approx. that were not taken into account during the first months (Wattson Anywhere portal data gathering came later)
For more details on my last 500 EUR update in April :
So the total savings as of today is 577 + 220 = 797 EUR, almost 800 EUR :)

I also sold few kits online to people around the world during the same period and it is still available here :

I will continue using it until I have a Tesla Energy Powerwall installed later .... and the beauty of it is that all the of the shelf components used in it will be sold and bring me a good part of my money back ;)
