Also you mention the solid state inverters from Jaycar, are they the Pure sine or the standard inverters in 800w?
The Jay Car reference was for solid state relays http://www.jaycar.com.au/productView.asp?ID=SY4086 for use with the Dingo to switch solar input up to around 80 amps with a good heat sink, beyond that you need a tunnel heat sink and fan cooling. You could either switch the on/off of an inverter like this http://www.ebay.com.au/itm/Pure-Sine-Wa ... 3f1081fb33 or switch the 240vac output using a relay like this http://www.jaycar.com.au/productView.asp?ID=SY4084, which has it's good points of the inverter not trying to start up under load if the charger starts up as soon as power is supplied, but the disadvantage of wasted stand by current of nearly 1 amp eating up your solar input.
If the charger goes through a check system mode before actually starting the charging process I''d go for wiring into the on/off rocker switch in the inverter and switching that with the "G" terminals in the Dingo.
Program 4 on the charging side for the Dingo allows a lot of adjustments to bulk, absorption and float voltages and the length of the absorption stage from mins to 4hrs. They are quite a good bit of gear for the money, and best of all, they are Aust made, so a call to the help desk puts you in touch with an Aussie speaking engineer if it's a really tricky question, but the young lady on the switch can answer just about any question you throw at her, a very switch on company.
