Load balancing with batteries

[requiemmg]

Hi, Until niw, I have a simple setup wirhout batteries. But these will be installed in rhe next days. So I wonder ifvtherevis a kind of power management and how thus affectsbthus plugin. If course Id want my Machines to start before batteries are being loaded...but is this already managalbe?

[IngmarStein]

At this point, you need a more elaborate power management solution which allows you to prioritize consumers. You might be able to configure this with https://www.home-assistant.io. I hear that http://solarmanager.ch is also planning support for Miele devices.

[requiemmg]

Well, actually not quite. While I'd like to have this in HomeAssistant, there is currently no plugin available which would actually allow to send the start signal.

My batteries were just installed and as I thought, they are automatically priorized. While this plugin currently monitors excess power, this would lead to the machines being started only when batteries are full and there is still enough surplus power.

BUT there is quite a simple workaround (ok, simple for people who can code better than me), as you would only need to check a second Modbus parameter: sensor.solaredge_battery1_power

So the start signal could be sent if either the sensor.solaredge_m1_ac_power (which should be the one you are checking now) or sensor.solaredge_battery1_power is above the set trigger.

This would be a huge relief for me, is there a chance you add it? I'd like to reopen this as a feature request.

(Of course, this option could be made optional like a flag -overrideCharging, then you could choose if you would prefer loading you batteries or running your machines first).

[requiemmg]

Addition:

If I understand your code correctly (I'm not at all into Go), this is where you read the corresponding parameter:

func (s *server) currentPowerExport() (float64, error) {
    inverterData, err := s.mb.ReadHoldingRegisters(inverterDataBaseAddress, 40)
    if err != nil {
        log.Printf("error reading inverter registers: %s", err.Error())
        return 0, err
    }

If so, I think all that is needed is the register Address of the corresponding battery charging value. Should be available from https://knowledge-center.solaredge.com/sites/kc/files/sunspec-implementation-technical-note.pdf I think?

[IngmarStein]

I see. So you're using SolarEdge batteries whose state is published along with the meter data on modbus? In that case, it should be possible. It's a bit more complicated than what you describe because the documentation you linked to is incomplete (see https://github.com/nmakel/solaredge_modbus/issues/18#issuecomment-748448500). sensor.solaredge_battery1_power is something from Home Assistant. Fortunately, https://github.com/nmakel/solaredge_modbus/blob/master/src/solaredge_modbus/__init__.py#L598 has the schema how to parse the battery block, but I don't have a battery available for testing (yet). So it would probably a back-and-forth with you for testing builds. Would that work for you?

[requiemmg]

Absolutely! Maybe the modbus multi extension for solaredge from WillCodeForCats might also be helpful, at least he is scraping data from there... ( https://github.com/WillCodeForCats/solaredge-modbus-multi )

And yes, I have the SolarEdge StorEdge Batteries attached (2 Batteries 4,6 kWh each, but they are seen as one Battery by the system).

If helpful, I could also grant you access to my modbus-proxy so you can see the values for yourself, but I'd need a contact address to send you the data then.

[IngmarStein]

I've had a first shot at parsing the battery data, please give it a try. I'm getting an error when trying to read from the registers storing the battery data in my batteryless installation, but maybe that's expected. At the moment, it should just show you the battery info and print the instantaneous battery power. I'm especially curious if the floating point format matches.

[requiemmg]

Wow, you are blazing fast, thank you! I am at work right now but see if I can find sone time today to test this!

Hi,

this is the output from the new version when I set one machine to SmartStart.

Current state: Solar production is 7,5 kW, 1,3 kW go into the household appliances, the battery has 50% and is charging with 5 kW. The "inverter AC power" is showing the Panels to house production (battery charge is substracted in this value). The Meter AC Power is currently an import of 22 Watts (it is circling around 0). So this does not seem to be the correct register yet....

[requiemmg]

This is my dashboard from the SolarEdge Modbus Multi Integration in HA. The marked value would be the one I need. The Integration makes 3 virtual devices (Inverter, Battery, Meter); this is from the Battery section.

[IngmarStein]

What does mielesolar print right after starting?

Thanks! I mixed up the number of Modbus registers (16) and the number of bytes (32) in the CommonBattery model. Should be fixed now.

Ok, cool - much better. Now if there's a waiting device, you should also see the power reading from the battery, next to the AC and DC data from inverter and meter. I'm curious about that output.

Oh, seems I was too fast after you pushed your update and the newest version didnt get installed; just checked and tried again. Sorry for that.

A bit weird. Of course, I have no solar production right now. Battery is discharging at 950 Watts (my current house consumption, which is correctly in AC and DC Power, Meter with 12 Watts import is fine). So, the battery is discharging right now, I will check again tomorrow in the day when the battery is charging.

[requiemmg]

Oh, and it triggered my dishwasher now. I suppose because the battery drain exceeded the trigger value which would normally represent solar production in a setup wirhout batteries.

[IngmarStein]

Battery Power: 508852698040014476972397620482801664.000000 is what I suspected: the floating point format needs special care.

[requiemmg]

Ok, can I do something to provide more info?

[IngmarStein]

You could update again and report back the battery-related output at startup … and report any other behavior change you might observe because the last commit completely swapped out the modbus library.

[requiemmg]

Ok, great. Just updated. This is the output after startup

And this is the output for the waiting machine. Seems good to me (early morning, nearly no solar production yet and the battery has been drained in the night).

[IngmarStein]

Great! Looks like we're getting somewhere :)

So far, I've only parsed the battery data, but did not implement and behavior changes. The latest commit now add the battery power to the value reported by the meter. That is, the battery power is considered production and if the overall balance is higher than the threshold, the start signal is emitted, effectively prioritizing the appliances over the battery.

[requiemmg]

It works! Battery is currently loading over the trigger value, started my washing machine perfectly now! I am on my mobile device right now and will provide a log tomorrow, copy/paste from ssh session on phone screen is a pain... Thanks man, you are awesome!

Ok, got it anyway 😉

[IngmarStein]

Glad to hear that, and thanks for the logs for confirmation!

Also thanks for the sponsorship, appreciate it. As usual: feel free to submit more feature requests in the future. I will benefit from this one as well once I get the exact same battery as you in the fall :)

[requiemmg]

Hey, great thing. Improved my self sufficiency to over 80 percent in the last days, and this includes our 10kW heat pump. So look forward to your batteries. Thanks again fir all the work, Ill keep looking after this improvement. A possible improvent might beca switch to decide if you want machines to be started from battery (without actual sufficient solar production) or nit, but I'd not use it because it woukd drain the battery in the evening.
