Interesting.
Sounds like I need to have a good look at the insurance policy.
I had never heard of Licensed Techs for 12 Volt installations, nor the need for certification as in 240 volt or Gas.
Obviously I had for 240 volt. Something I have been thinking about while looking into Inverter installation.
Interestingly enough the Motorhome had an old 1500Watt Modified Square Wave (the ultimate misnomer) inverter installed by a so called Expert here in SA when it was bought new, along with solar panels, PWM solar controller and DC-DC charger. We bought it a few years old, used. It has an outlet on the exterior wall, below Mains input. Idea being to connect with extension lead, thus avoiding the expense of proper installation. We never use it. It is something I am going to look into if I instal an inverter though. I want it wired in properly (in A Van) with no temporary connection for use. Just turn on inverter and use any mains outlet.
The same installer installed a Redarc BC-DC totally incorrectly so nothing would surprise me. They had the house batteries charging the house batteries with nothing powering it from starter battery or alternator, nor any wire remotely large enough for the required current. Found a small shop in Broome on a 'Big Lap' with terminals and bus bars and installed correctly myself. Few years ago now.
Point being it is very hard to know who to believe these days. I certainly would not be going back to that installer though.
Where does one go to find such a licensed Tech?
Preferably one who can inspect and sign off on my own 12 volt installation and do any 240 volt installation.
My plan atm is to keep Lithium to A Van along with Inverter and external outlet to power Motorhome from Inverter when required. For use of 240 volt in Motorhome and top up SLA batteries in Motorhome via mains charger.
IE: Only changes being made to A Van. I am thinking medium term though of ripping out 3 way fridge and gas cooker to instal 12 volt compressor fridge and just using inverter to run coffee machine, electric jug, toaster etc. It is after all my Man Cave, not to mention relationship preserver.
Also thinking of a rack for small electric fat bike where gas bottles are atm. Great for beach fishing, collecting fire wood when bush camping, carting water in camp grounds etc. All with trailer I modified myself, both trailer and bike having 20"x4" tyres.
