Measuring data

[watervole]

A thought from Alex_Holden.

If I had two sensors with logging (My current one doesn't have a logger), then I could use one after the inverter and one in the usual position and get some really pretty graphs.

I can't currently justify spending £70 to get a pair, but I do like the idea of being able to see both generation and consumption.

How much power does the Owl use?

[watervole]

3 AA batteries. They'll probably last a year or so.

[davidwake]

Get rechargable ones and top them up every midsummer's day.

Surely the other end must be connected to something to read the electricity?

[watervole]

THey probably are rechargeables. I didn't look inside, but that's what we normally use.

It may use batteries at the other end, but I'm not sure where that part is attached.

[davidwake]

The write-up says 6 AA batteries, so I suspect the other unit is similarly powered. There must be some use in order to transmit the information to the portable unit.

[alex_holden]

Yes, there are batteries in both parts. The transmitter is connected to a sensor that normally clips around one of the thick wires that goes into the meter.
