I adopted a different strategy for showering...so this is no help whatsoever to your project, simply a different way of thinking about issue. I like to take long showers after a hike, but wish to keep power consumption and water use to an absolute minimum. I therefore use a recirculating pump in...

Exterior not aluminium. It is a converted minibus VW crafter....so thin sheet steel id imagine....typical van.

Moving RV. He envisions a short earth rod pounded in with a hammer and soaked with water. I dont fancy the idea myself, but everyone says that i must get the system 'checked out by a qualified electrician', but having done so, i'm now getting told frequently that he is wrong in his assertions...

Thanks for the replies folks....getting off topic when discussing boats, i feel. My comment on boats was only in relation to boondock's comment. I'd rather stay focussed on RV/motorhomes on insulated tyres. Thanks

@mikefitz Thanks mike...that was my thinking. Are you are qualified electrician by any chance? Could you please point me in the direction of the relevant section within the 18th edition regulations, so that i can argue my case with my 'electrical expert' friend. Thanks for your help.... this...

@Boondock Saint Thanks for your reply boondock saint... I thought i had all the grounding worked out, but a qualified electrician friend has thrown a spanner in the works by insisting that i need an earth rod for RCD protection. As regards boats, if they have a metal hull, would this not...

Thanks for all the replies folks. I have an electrician friend that insists i need an earth rod for the RCD to work.

In a rubber tyre insulated motorhome, is there any downside to attaching an earth rod to the chassis when parked up, when using 240v ac inverter power only(no grid tie or grid earthing) ? Is it safer with the earth rod connection or not?

In a motorhome setting with the vehicle insulated from 'true earth' by rubber tyres, does the RCD in a 240vac distrubution board still trip if either the live or neutral cables make contact with the van metal, when there is no true earth, only grounded to the vehicle chassis? On developing the...

Some paramter settings i'm going with: Charging... Inv/charger: Bulk =3.4v(27.20v), Absorb(taper down) 1hour,Float = 3.35(26.80v) Solar charge controller: Bulk 3.4v, Absorb 10 minutes, Float 3.35v (i never want my cells to be sitting 'full'). Discharging... Inverter/charger: Cut off...

The pack compression is such, that the wood can move freely under the bottom of the cells.

Some of my setup modifications i have made are: Placed a layer of compressible insulation between the battery cell faces. Installed 6mm to 10mm aluminium flanged studs on cell terminals. (All connections torqued to 4Nm) Installed flexible braided busbars across cell terminals and from cell pack...

I'm getting the distinct impression, that as popularity rises with these cells(across several vendors), 'lesser quality' is being slipped into the mix. I might be wrong...just a feeling i'm getting, the more threads i read lately???
