Our third drawer, the smaller one, had the remaining four battery cells installed and wired up. We swopped out the isolating switch for a heavier duty model, capable of handling up to 100Amps. It is now ready to be installed into the cabinet itself.
We got one more drawer which is empty at the moment but we may invest in buying some more cells next year if we deem that it would be useful and help us capture more Solar and cheaper electric rates during the off-peak periods. We also will wait until the pound grows a bit stronger again as we have to buy the equipment in American Dollars!!
