My E-Life Now !: DIY ESS - We're moving !

Like I was writing few days ago, we are going deeper into fall and the temperature is decreasing rapidly here in Paris; It is the perfect time to go ahead and move the ESS upstairs, from our bedroom to the living/dining room, to be able to use the Forced Charge Mode at night, when electricity from the grid is cheaper thanks to our TOU (Time Of Use) plan.

I had planned this move several weeks before, and yesterday was the right time to do this because we started using the heating again (Daikin heat pump) after several months of no use at all: The only very heaving stuff is the battery pack, and it is easy to break it into several pieces

First thing: Switch everything off: the Main Control Board Switch, then the AC breakers and the Battery Pack DC Breaker

So here I started unscrewing the battery pack terminals and removing the cells two by two

The modified Wattson is also unplugged from the Control Board and removed from the top of the metal cabinet

All the CALB CA180FI cells have been removed from the cabinet and moved two by two upstairs

Then, the biggest part: the cabinet is moved with all the rest in it: Chargers, Control Board, Grid Tie Inverters and Cables; the ESS is installed in the living/dining room here on top of the stairs

I left the cells in the exact same configuration and asked the kids to stay away from them (!!)

During the moving some items moved a bit and I had to rearrange them

Now I am putting the batteries back where they were ...

Et voila !

The modified Wattson has been plugged back into the Control Board, and the second one is still displaying the Generated Power

After switching back to on the Battery Pack DC Breaker, the Control Board is now energized again, and I switch on its Main switch: The Arduino board is powered and goes through its initializing sequence, the ESS is now fully on and in Charge Mode
