-----strong possibilites for the "Battery-Bank' implementation you suggest,but a reservation or two!!
As I understand it the Bluegen produces A.C. power whilst your batt-bank would,of necessity,be D.C. power.
Thus a Transformer wud need to be introduced 'twixt the B.G output ---Batt.Bank??
UNLESS,of course,our Bluegen produces D.C. power which is "Inverted' to A.C. via the Smartmeter??scanno
