What / where to feed the kWh imported and exported

[marcelrv]

Hi @nmakel thanks for your solaredge proxy. I'm feeding info from my Dutch P1 meter to Solaredge. This output provides separate fields for import & export The current import/export W for solaredge is working fine with calculating export-import.

I'm struggling to understand what the solarEdge expects as values for the export & import KwH I was feeding the meterposition (electricityDeliveredT1 + electricityDeliveredT2 & electricitySuppliedT1 + electricitySuppliedT2) to it by supplying the meter in export_energy_active and import_energy_active but that gives very odd bar in the solaredge app as it seems my total import and export in a single day.

Do you know what SolarEdge expects for this, is it a value that resets every day, or every hour, never (as I was expecting)?

Note this is what I get from my meter (using https://github.com/mcrapts/p1-reader to convert to MQTT)

Here you see in my week consumption 4.05 MWh which is a biiiiit too much ...

Here you see in my week consumption 4.05 MWh which is a biiiiit too much ...

So this is probably a unit issue. I also ran into this accidentally during debugging. To remove this value from the dashboard I needed to open a ticket with SolarEdge support. With a bit of luck they can remove the erroneous values from the graphs.

[marcelrv]

Thanks for the input. I'm running the script now for couple of days. It happened 2 times more that it had and will indeed create a support ticket for removing those. Still awaiting the day I see matching numbers for energy in the portal . (power is working fine). The strange thing is that I see the correct values for the energy on the powerEdge itself. (at least I see the total meter kWh for import & export)

What I noticed is that for me the timeout settings have a very big impact. I somewhat expect that the strange numbers are cuz of data errors when I was setting various timeouts with timeout 1sec, the device get stuck on requesting address-1601 with timeout .1 I see requests for 1601, 1651,1701, 1001, 1101,2128 and many 1011 every seconds there are quite a few request for 1011, than every 4 sec the others are requested.

Is it normal to have so many 1011 requests (I see around 8 requests/second) or is it some sort of error and it is not happening with a regular wattnode?

What is unexpected / strange in your example is the energy_active , as acc to the spec I was assuming it is the export - import, but in your example you have it as import+export

[marcelrv]

Note, I assume the Energy shown in the screen is suppose to show the current meter value, not the daily number right?

I can say that I finally had 2 days that everything fully matched, import & export included. The trick was the setting of timeout = .1 .

dunno if the rootcause of the issue, if it is something in the hardware, or the pymodbus or something in the solarEdge that causes the behavior.

[nmakel]

I'm feeding...

Check your p1_current p2_current and p3_current. Those should be l1_current etc.

My unit does not have a display, so I cannot confirm, but it sounds right.

Great news, thanks for letting me know! The timeout value is good to know, I will add that as the default -- my setup is based on RS485 to ethernet converters, so I never have this issue.

[nmakel]

Are you using the latest solaredge firmware, by the way? Just to confirm this still works on newer firmware -- I have mine locked to an older release.

[marcelrv]

Before installing the energy meter I updated to the latest firmware for inverters with display: Version Date July 2020 Single Phase Inverter with HD-Wave Technology | CPU 3.2537 | DSP1 1.0.1036 | DSP2 2.0.910

So, yes it still works.

[marcelrv]

closing as it works perfect now
