I installed a bc12-12-15
. Got from Jean Theart in cape town. Will find his details and post. Cost R1780. I chose this above the C-tec system as it has a built in load shedding function - I.e. when battery 2 is charging, fridge is connected to main battery, therefore proper charge is delivered to battery 2. ctec can do this by adding another unit, but costs are prohibitive. Will post pics soon... Busy moving house...
