Well a few special moments from today
1- going through handover and chap starts telling me about my fridge, which I selected the Waeco RPD218 which is a 12v 240 only fridge. I asked him to turn off battery and show how it selects the power source. He flips the cct breaker and the fridge promptly turns off. I ask why and he says my fridge will only run on 240 and the tow car battery. Says they don't connect it to the house battery as will drain them to fast, blah blah one chap drained his car in a hour (bet it was 3 way, and no house batteries in the van). At this point I'm about to flip thinking my upgraded fridge isn't connected to the house battery and already thinking I'll just rewire the van myself. He gets to the drifter and then he turns in the house battery, I notice current draw increasing as he's turning on all the lights. Anyhow he steps out and I soon confirm YES is connected to my 2x 100amp hour batteries and my 300W solar, and confirm its current draw on the drifter as under 5 amp hour. So almost lost it.
2- hit home and connected the van up to the EU20 and runs fine. Couldn't get the hot water to run on 240. Read the manual and need to Flick switch on outside HW panel
Solar Reg he had no idea and couldn't tell me how to see the incoming solar amperage to batteries, only voltage which is useless, manual told me.
Sorry to hear of your problems ...hope it hasn't taken the shine off the new van excitement.
Re fridge....that's interesting as we are moving to a different fridge as well and just can't understand the rationale of the wiring from the factory. (Non Jayco)
Your Waeco would seem to have an electronic panel which automatically selects the power source and does the change for you? Our Thetford will have the same.
I'm not sure of the Waeco instructions for wiring but the Thetford wiring instructions specify what you seem to have...reason being the risk to the van and/or car battery if you don't disconnect from the car almost immediately and let it detect another power source. They state very clearly that wiring, on12v,should not be to van battery and to disconnect from vehicle ASAP. My dilemma is that I'm now unsure how the stupid electronic panel is supposed to operate when off grid. If the 12v is not wired to the van battery, how does the clever clogs fridge get power so it can make all those smart decisions?
I'm following it up but will be interested to hear how yours is set up and if it works ok, once you've sorted it out. (I know the fridges are different but I think the possible problem is similar...ok on 240v, OK if getting 12v from car, but not wired to van battery)
Why can't they just let us choose the power source ourselves??? and not complicate things unnecessarily?
But the van does look good!
