The rest as they say is history! Peter found a $20.00 case and Geoff Adcock the CMCA sparkie popped it all in the box and did a superb job on this. Now this unit is not 100% electrically safe but using double insulated devices it is does have a much higher safety factor than if it was bolted into the motorhome as was originally intended. Geoff made up several leads for charging and running other devices. Everything is fused and overall a really nice piece of equipment that works well for Peter's purposes. Geoff popped the inverter on his oscilloscope and found that it was a sine wave type but it did have steps. From our own experience of buying all the wrong inverters (trying to save money!) is that you are better off paying your $500+ and going for Australian brands such as Selectronic, SEA etc. We have never got more than two years out of the cheaper ones so feel that these are a waste of money and they are of course never as safe. Our best advice is to buy from RV specials - usually solar shops such as Solar Panel Express etc.
