I'm looking for a power monitor for the EHU.. basically a panel mounted digital ampmeter with a range 0 - 16 amps.. or wattmeter.

I know Maplin sell 13A plug in types but has anyone seen a panel mounted version ?

Thanks Jim

PN 8247 looks just the job, I'm familiar with Bluesea products, but I'm struggling to find a UK retailer, they only list wholesalers, ..but I'll keep looking

Cheers

Hi Bryan

Not wide off the mark, thanks, ideal size,
but it needs a CT (current transformer), not sold by the seller.
Someone somehere will sell both.. just need to keep lookiing..


As an aside, you would think this would be a popular thing to have fitted in a motorhome, or as a retrofit, I know the yanks fit them now.. :RollEyes:

The 20 amp one I linked to needs a


'20A 75mV Shunt must be used for the meter to read/measure current.'

Is that any easier to come by or is that an expensive hard to get extra too?

just remember
IMPORTANT: A 20A 75mV Shunt must be used for the meter to read/measure current.
a shunt or transformer is needed with these meters which costs more than the meter itself.

Ideal and easy to install :thumb:..


Jim

but, as usual, Jim.......they're out of stock.
give 'em a ring and ask when they will be back in stock.

i ordered an 'out of stock' solar panel from them. after 3 weeks i rang them......"they will be back in stock in 11 weeks Sir"
needless to say i cancelled the order.

Sorry Jim, thought you wanted amps...the kind of unit you mention is similar to this : Link Removed which I use at home :thumb:

BTW, neither unit is true panle mount but I'm guessing that you'll mod it to be so :rofl:

Power Monitor update

Hi

The monitor arrived and its fitted and working, shows the Real-time consumption and can be programmed to give audible alarm when it exceeds a preset limit.

Simple to fit, the Clamp just goes round the positive Incommer to the Meter and with batteries inserted a press of the button and the sender "finds" the Recever and "bingo".

Some of the results (about the house) are "illuminating" Viz:-

Tumble dryer 3+KW/hr:cry: Oven 2.5KW/Hr:Tongue1:

Biggest reading was 18.8 KW/Hr during Sunday Lunchtime, when the House was full of "visitors" for lunch, and SWMBO was doing a batch of washing as well!!! :Doh:

R-V (with passive heating on) 3.5KW:cry::cry::cry: Time to go to Spain!!!::bigsmile:

To fit it to the R-V I will have to isolate the Positive Incomer, you cannot just clip it round the EHU cable, it distorts the reading.

So far well worth the £30.

Pete
