Double read

by Bigbillyg on

Hi all when I look at minute tab the reading is double to what is on my solar inverter

Have I wired the flukso meter up wrong I and using kilowatt hour meters with pulse out puts.

Thanks brett

Yes, it'll work; factor to be set in the configuration then is 0.5 for the pulse sensor (this is what I actually also use)

Could it be the cable that runs to the flukso box from the pulse meters? Been to large

No. If values are shown and they are doubled to what they should be, the factor set in the configuration is wrong... so, check on the sensor config in the web interface.

So the factor should be set to 0?

Thank you for your help

Do you mean under sensor the constant should be set to 0?

Not "zero", but "zero point five" equivalent to "one impulse quals to half a Watt-hour"

See installation manual, page 8 - for 2000 imp/kWh the "fractional meterconstant" is 0.5 - quote:

  1. Ports #4 and #5 on the screw terminal are pulse ports. They are mapped to sensors #4 and #5 respectively. A meterconstant de nes the amount of ow represented by each pulse. For electricity, the unit is Wh per pulse while water and gas are speci ed in liter per pulse. Fractional meterconstants are allowed down to 0.001.

So if I had a nother pause meter that was 1000 I/kwh the fractional would be 1?

Exactly - the Watthours per pulse.
