It was a pleasure to meet Wayne and see the great job he has done of upgrading the previous fit out. Margaret was very impressed with the amount of room inside...... fortunately I think I convinced her that we couldn't buy it and take it back to Mannum 
This system has an added feature, it has a load relay driven by the Dingo designed to power a 24v water heater element so excess solar is automatically utilised for water heating or any other device connected to this load relay and turned on at the time. There is also a 3 way switch added to allow auto operation, off and manual by pass if the battery pack didn't quite reach full but had enough spare capacity to allow a hot shower.
It the inverter photo another relay can be seen in the upper back corner, this is for the lithium control system to control the charging part of the inverter/charger is a cell goes high voltage while charging by forcing the charger to stop and the inverter to switch on so the high cell is pulled down.
Even while it was raining.... which was 90% of the time and another 5% it was hailing..... the solar still continued to charge and an equal amount from the from 7 panels as the back 7 panels (the 2 x 40 amp circuit breakers allow each set to be disconnected for testing etc. The best we saw with the sun at poor angle of alignment was 54.5 amps @ 13.6v so only just better than 50% so it will be interesting to see the output during better solar conditions.
