Hi,

Recently had a PV system installed with a X1 Hybrid G3 Solax inverter. Solax provides an online portal showing stats for the system production and how much power is being consumed from the grid. The figures from the portal and those from the power provider are not even close. The Power Providers figures show upto 80% more power consumed. Has anyone else got the same of similar inverter, are you getting accurate power metering?

Cheers
D

Mention this to your installer

Have been trying to get an answer from the installer for over 2 months, with no joy.

Want to see if this is happening with any other Solax inverters or if it is a localised problem.

rogercruse:...Mention this to your installer...

We've got two different brands of inverter: Zevercloud for our panels and SolarEdge for our battery. Both are reasonable accurate.

This is the data for Jan 01. Solax showing 0.47 kWh consumed and Provider showing 2.47 kWh. The difference of 2 kWh is not consistent.

I have a solax x3 hybrid inverter and had similar issues to you.

My problem turned about to be a faulty Chnt meter that was installed in the switchboard as part of the solar install which was giving faulty readings to the inverter. For me, the sola x portal was not giving acurate data on pv energy used, not seeing all appliances that were operating, and power exported.

All sorted once the chnt meter was changed

Who was your installer?

Provider - ,

Solax -

Excatly what my problem was

Edit: The main thing is that the inverter will still be using the pv power on all loads so you will utilising all you can before being exported to the grid

Very low probability of this but worth a check... is there anything else between your meter and your inverter? I.e, we are on a rural property and three-phase main power with meter initially terminates at pump house, then there are two submains, one to the house and the other for the man cave. If we put the inverter at the house submain then that wouldn't count any consumption from the man cave or pump house.

Otherwise either the main meter or inverter is likely to be out of calibration.

Edit: I think darkasdes2 is onto the likely problem ;-)

Thanks darkasdes2 - good to know that there is a solution. How did you pinpoint the CHINT meter? Is there a way that I can test that it's the culprit?

System was provided by World Solar

Mine was installed by world solar as well.

Who was the sales agent for you?

I was orgianlly contacted by Doone and then Ricky was my sales agent. I went through some testing with Doone by doing some load testing. Doone was also in contact with his sparkie and supplier and they decided to change the chnt meter. During the load testing like tuning on heat pumps etc they was no change in the sola x portal.

Maybe they got a bad batch. I will pm Doone email address to you.
