"An ESS is an Energy Storage System and its purpose is to store surplus energy, not used in your home, to re-use it later throughout the day or at night when solar generation is down;

It can also store energy from wind, or any other generation mean, even from the grid itself: you can help shave peaks and save money charging at night when electricity is cheap, and discharging during the day when it is expensive
My LiFePO4 DIY Battery ESS is an On-Grid Standalone System for people who already have solar or/and wind installed and would like to become even more grid independent

Using an additional inverter, it should be able to supply power inside your home - or office - only, in case of a power outage / black out"

Hi Kevin

Yes, I have seen Christophe's kit and would be really interested in an ESS. His product has the benefit that it is a true retrofit solution and does not need an inverter change.

I looked at his instructions and while I understand what's going on I think that it's way beyond both my technical ability and also risk aversion.

I wonder, now that Wattson offers OptiPlugs whether some of Christophe's solution already exists in that it would be possible to power a charger only when sufficient excess power is in the system.

Those batteries look very small to me! It doesn't say how many kWh you can store but they look smaller than an EV battery
8 x CALB 180Ah LiFePo4 which is 4,608 Watt-Hours (enough to power a 1kW electric kettle for 4.5 hours) and nothing stopping you adding more storage if you wish :)

It's easy to imagine that a system of this size could meet you evening energy requirements if you've run the heavy loads like dish/clothes washing during the day when the sun is out.
