Its an upgrade for us - the Microcare is only 1 Kw and the Axpert is 5Kw and within our dwindling budget. Also Microcare can fly a kite as far as after sales service goes - I have had a problem on both the controller and the inverter in the 18 months we have used them and I got sweet fanny adams from Microcare when I approached them for help - they refused to even talk to me as I wasn't an "approved intaller or distributer of their products". I had to sort out the issues myself, which I did manage to do. They will not see a cent of my money again and if anything goes seriously wrong, the stuff will become expensive sinkers for fishing.

I thought to use the existing system as is for a separate circuit for fridges and freezers. Then use the new lot for the rest?
According to Trojan the batteries should have a life span of 14 to 17 years at 80% DoD if looked after properly. This is why I ask if the 18 month difference in age is enough to be a problem.
