If you have Solar or/and Wind installed, you probably Produce more Electricity than your House is using
With this System I developed over the last two years, using Top of the Line Quality LiFePO4 Batteries from CALB, Chargers, Grid Tie Inverters, and Control Board, you will be able to capture the Excess Generated at Home and ReUse it when necessary: when the sky is grey during the day, when your house AC loads require more than your Generation, and of course during the Evening, when the sun is not shining anymore
This LiFePO4 DIY ESS is currently installed at my place, inside my apartment, and does all this Automatically
I first built this for myself, but now it is working well, I want to share this Low Cost Solution with others all around the World
You can also store Low Cost Electricity at night and reuse it during the day when its price is higher
Residential Energy Storage is Hot Topic right now and Incentives for these are given in Germany, Netherlands, USA and Japan
But these Energy Storage Systems are usually very expensive, and I built a Solution that does exactly the same, for much less
Also my knowledge of LiFePO4 Charging and Discharging, overall Battery Management Method, allowed me to have 0 Incident with 2 Brands of LiFePO4 Cells so far; I know what I am doing
Finally this ESS Battery Pack can be used in case of Power Outage / Blackout, by simply connecting a regular (not grid tie) inverter to its terminals, and provide Power for home appliances
Now it's your turn !
DIY ESS Kit #1 is composed of the base to build your own LiFePO4 ESS :
- The brain of the system : Arduino Leonardo board flashed with my Program : Save hundreds of hours of testing, tuning and programming
+ PROGRAM
- The Kit Building Documentation: Detailed steps to build the ESS, even if you are not a specialist
- The Components List: Simply lists all the Components needed and the Vendors contact details
- The User Manual: The daily use instructions, including Safety and Battery Pack protection hints
And this is what you should get:
The Kit I am selling is composed of:
- Arduino Leonardo Board, flashed with the Program I developed
- Detailed Step by Step ESS Building Documentation
- Components List and where to get them
- DIY ESS User Manual
- Grid Tie Inverters : the SUN250G has been a very good GTI for years, is more efficient than a Power Jack (similar product); they can be used in parallel, their DC input accepts 10.8V to 30V, which is perfect for my 24V battery bank; They have a one year warranty; They are very affordable, , 110-230VAC
- Relays : Small standalone design, with red led to indicate that it is closed/active, standard connector, low cost, have been working for the last year now with no failure; If any, each relay can be changed in 1 or 2 minutes with a small screwdriver
- Controller : The ESC (Electronic Speed Controller) used is probably the best in the world, Made in the UK, micro-controller based, does not heat up and can carry high current up to 40A at 26.6V which is more than we need here;Product Link
- Voltmeter : This programmable dual relay digital voltmeter is the key to monitoring the Battery pack charge and discharge limits, and keeps it in the safe range; It is available only in the USA, is easy to program manually, is precise enough and does the job !

My System is based on Quality Components:
- Energy Monitor: Created in 2006, Wattson is for me the best: it displays clearly in real time your home Usage, Production & Net usage with large visible digits and colors; Using RF, it can travel in your home since it is also battery powered; Easy to install and it looks like a design object
