Minimum wattage of the power clamps

Hello everybody.

I'm new here. I have installed 2 current clamps.
1 on the main cable, for my total consumption of energy.
1 on the solarpanels cable.

When the solarpanels starts up my inverter begins with 1 watt and goes on to almost 2000 watt. But when i see THE grafics on flukso, iT start with almost 200 watt?!

When my house consumption is around 400 watt, and my solarpanels give around 400 watt back, THE clamp of the Total consumption must be around 0 watt!!!
But both of THE clamps have no grafics between 0 and 200 watt!?!
So whats happening?

Hello Hans,
First of all, a current clamp is not good to measure solar because of bad power factor in low power ranges.
Several times that this problem is coming back and discussed here on the forum.
To measure the solar power right, you must use a kWh meter with SO output that give pulses in the order of 500, 1000 or 2000 pulses /kWh.
Then set the sensor correction factor accordingly on 2, 1 or 0.5.
A example of a din kWh meter here:

For your second problem (both clamps that have no graphic), perhaps another Flukso owner can help you out for this...but...
What graphics do you mean ? w, wh or cumulative and in what time-frame ?
Did you have a graphic with only one clamp (consumption for example) ?
How are your sensor settings for both consumption and solar ?

Everything is fine now. I bought a din rail s0 meter with 1000 pulses per kwh.
The description on the s0 meter said that the voltage of the pulses must be between 12v and 27 volt. But I connect the flukso and measured with a voltmeter, and it works perfect! With 3,23 volt!
Somethimes life is so cool...
So now I have everything connected.
Main electricity, solar panels, gas and water.
It left only 1 thing.
I want to capture my woodburning stove with watercompartment.
I allready have a watermeter installed on it.
Yesterday it warms around 700 liter water from 25 to 60 degrees. (To my radiators and my floorwarming). I want to bring that on the map, so I can see which days are cold, because I use only gas for showering and bathing.

Maybe flukso can inform buyers in the shop, the clamp will not work with solar panels.... And maybe some other electric devices.

That should help us and them...
