I am currently evaluating Wonder Watt and came across the Inverter and Battery Settings in the advanced section. In the Advanced section of Wonder watt you have a Max Inverter Rate (Charge/Discharge) and Max Battery Rate Charge/Discharge setting that you can record. Why can't you record separate values for both Charge and Discharge for Inverter and Battery rates as they can be different. My GE inverters combined Dual AIO power is 12kWh in 12kWh out. However, I have a DNO limitation Outgoing of 9.5kWh. So it occurred to me that in Wonder Watt it would be better to record both Charge and Discharge Rates and not assume one size fits all. It also occurred to me that users may want to charge / discharge more rapidly or slowly depending on a given situation. Therefore in the section where you can create schedules it would be useful if you could optionally enter charge / Discharge Rates for each schedule that you are creating. One thing to note is that if like me you have a GE dual AIO setup then when Wonder watt sends the Battery Discharge Power = xxxx command to my system this command Does Not Work. However, the Discharge Power Percentage does work. So in settings section a field to record whether the system has dual AIO's would be useful to determine which command to send depending on the system type.

Is this guaranteed to work for any dual Giv AIO combo or is this possibly a firmware issue?

Plus 1 for the separate Discharge/Charge rates [as previously discussed]

@"admin"#p8275 GivEnergy and Guaranteed in the same sentence.... Interesting concept

@"admin"#p8275 I don't know if its a bug or not but as I said Watts Value dosn't work Percentage does work on dual AIO's. I have an open support ticket ongoing at the moment on a issue so I will try to find out and let you know. and will you consider being able to specify a Charge / Discharge rate in the scheduler to speed up slow down specific schedules. I have been doing some tests and I get more out of the discharges if I run at around 50% max capacity. I just changed from Agile to Go and I cannot get IOG with the GE Charger and the MG car I own. However, If I could adjust schedule execution speeds I would be prepared to pay for that feature although 90% of Wonder Watt wouldn't be any use to me.

@"admin"#p8275 Regarding the firmware I am on the very latest not released V13 Gateway, AIO V13 BMS AO.618

@"admin"#p8275 If I explain a little bit more why being able to set a charge rate in a schedule is useful. Having a dual AIO system is good if you want to import at 12kWH and is good for sucking up lots of KWh's in a short space of time. However, it can be a curse also. I have the GE EV charger which does not support dual AIO's so All the cloud settings such as "do not drain the batteries" do not work. Therefore if you are on GO like me you start a charge on the batteries at 00:30 and charge the batteries to 100%. Now unless I go into the portal and mess with the Battery Inverter Percentage setting in addition to the Start and End Time settings, the charge will commence at 12kWh, If the EV needs charging I will fire that up which adds another which because we are already charging will take power from the grid rather than the batteries. However this adds another 7.2kWH to the load, so now with the dual AIO's running at full chat along with the EV charger I am one kettle boil away from exceeding the 80amp Gateway Limit. I have done this and the Gateway crashes, shuts down, the house power goes off, and is a nightmare to get up and running again, a full afternoons job. So I would like a schedule called EV Charging Tonight it would run from 00:30 to 05:30 and I would set The Battery Inverter Percentage to 45% this would give enough power / time to fill my batteries from 10 to 100% and give me the headroom to charge the EV without getting anywhere near the Gateway limit. The beauty of this is that all the settings get set back after the schedule completes, something I always forget to do which is always costing me money. So If you can implement this request then I will subscribe just for that feature alone as it will be worth it for me.

@"admin"#p8275 Hi, So I have an answer from Givenergy regarding the Battery Charge Power and Battery Discharge Power command. They are NOT supported on dual AIO systems. The Gateway ignores the command and does not pass it on to the AIO's it's by design and not a software bug. Therefore in your Advanced section of Wonder watt you need to ask the question is you Givenergy battery an AIO. If yes then send the Battery Charge/Discharge Percentage values in your commands instead of the Battery Charge/Discharge Power watts values. So In summary in the Advanced section of Wonder watt Record if their battery is a AIO Users can add Battery Charge/Discharge Value and also Inverter Charge/Discharge Value or Record if the user has an AIO then only record a Battery Charge/Discharge Value Add a option in Schedules to record a per schedule Charge/Discharge value that overrides the advanced value. This gives significant per schedule flexibility to control the charge/discharge rates on a schedule by schedule basis. As I said above if you can implement the above I will instantly subscribe to a full year. As It will mean I only need one utility to control my battery system. Well worth it IMO.

@"duplada"#p8293 What is your WattID (under version number in the navigation menu) please? So we can check the logs. Don't worry - think we've located you, we will look at implementing this. Anyone else with a dual AIO set up here who has noticed the same issue?

@"admin"#p8294 It's circular-strategy thanks for including the feature I look forward to it's implementation in due course thank you.

@"duplada"#p8295 The information re the command being not supported on Dual AIO's came from Paul L

Separate Charge / Discharge Settings for both Inverter and Battery + Schedules

admin open-departure Thank you

Capt_Rich Sorted for you.

admin Yep - the question is, would those custom rates take precedence over the global rates?

I have a few thoughts as usual,

Are we still going to get a separate Inverter Rate for Export in Advanced Settings?

My Inverter Rate is set to 12kWh in advanced but my DNO export Rate is 9.5kWh. If I want to charge at full rate 12kWh then I have the Inverter Rate in Advanced settings set to 12kWh. However with the Inverter rate set @12kWh WW makes incorrect calculations for "adjusted" End Times on Export Schedules because of my DNO limit for Export is 9.5kWh but WW thinks I am exporting at @12kWh, there is no way around this unless there is a setting in advanced for both Inverter Charge Rate and Inverter Discharge Rate.

admin Yep - the question is, would those custom rates take precedence over the global rates?

As it stands we have an Inverter rate for each system which is dual purpose both for Charge and Discharge, why not add in Advanced settings a Discharge Inverter Rate (as discussed above). These two rates are then the Maximum Global Rates for both Charge and Discharge. Then In Advanced Settings, allow users to create say 5 Charge and Discharge Rates which can be named similar to this. The Watts will be calculated as a percentage of the Individual Global Charge and Discharge Rates defined in Advanced Settings.

Then in the Scheduler, if the Schedule is a charge Schedule and the user selects "Adjust Charge Rate" the Charge / Discharge Rates Menu would be displayed for the user to Select from as below.

If the Schedule is a Discharge Schedule and the user selects "Use Current Discharge Rate then the user can choose the required rate from the popup menu of available rates.

The system described above would if implemented solve the long standing issue of the missing Inverter Discharge Rate, providing accurate WW calculated adjusted end times and allow user defined Charge / Discharge Rates to be applied to any Charge or Discharge Schedule.

Is that not solved by simply using the Rate Limits and set Max Discharge Rate to use to 9500W? Your export schedules will use that then, and the calculation would be based on that.

With regards to named schedules, we hear you - it's in the pipeline, though we will likely keep 'Auto charge rate' in place, and if toggled off allow a selection of charge/discharge rates as you describe. The idea being that we don't want to overwhelm new users that haven't 'grown with the system' and present them with yet more things that require setting up before configuring a schedule.

So if the WW "Adjusted" End Times are going to be calculated by the "Rates" settings then what will be the purpose of having the current Inverter Rate set in Advanced? or is that for users who don't have the Rates system active?

Well why don't you pre populate the Rates table rates in Advanced with 100%, 50%, 33% 20% 15% and Allow the names and rates to be edited by the user if need be. That way there is no extra burden on new users and the whole thing can be over and done with in one go. I here what you saying about the pipeline but I can see me chasing this up in another six months.

As it stands I have more than 1 rate that I regularly use for both discharge and charge schedules. So whilst the solution that has been provided is welcome, but it is really only a halfway house as I will still need to be in and out of advanced settings continually resetting the rates depending on the days tasks etc. The only way to truly Automate this is to be able to apply the charge / discharge rate within the schedule. In the short term could you not provide a popup menu in the schedule with a range of charge percentages 75%, 60%, 50%, 40% 30%, 25% 15% 10% or whatever, that the user could choose from if "Adjust Rate" is on in the schedule.

admin

duplada So if the WW "Adjusted" End Times are going to be calculated by the "Rates" settings then what will be the purpose of having the current Inverter Rate set in Advanced? or is that for users who don't have the Rates system active?

Backwards compatibility and indeed for users who don't yet have this. At some point, the other rates will disappear and we migrate settings over.

duplada I here what you saying about the pipeline but I can see me chasing this up in another six months.

Have a little faith, please. It will be here sooner than you think. It will be live before you know it.

duplada

admin So what's the timescale ?

duplada

I have run a number of Export Schedules 5 in total using the New "Rates Limits settings" outlined above. I had my Max Discharge setting initially at 80% Which equates to 9600 Watts my DNO Export Rate is 9500 Watts. During the Export Schedules I was observing what was happening. The time Calculations performed by WW where it needed to make an Adjustment to the End time were spot on. I did experience an issue with the Export rate despite being set to 80% (9600 Watts) my system was only exporting at 9300 Watts. I spotted this and manually adjusted the Discharge Power in the Portal to 82% 9800 Watts which then upped the Export to the Grid to 9500 Watts ( this is a GE issue nothing to do with WW). So Export Schedules worked without issue.

Edit after some checking of my Schedules it would seem that each one that I ran tonight DID NOT have the Discharge Rate setting on, So they should have executed at 100% Discharge Rate (Have I got this correct I am getting myself Confused now)

Use Discharge in Schedule Set On = Rate used is the rate set in Rate Limits
Use Discharge in Schedule Set Off = 100% Max Inverter Rate

I have some charge Schedules planned for later in the weekend where I will be limiting the charging of the house batteries to below 50% when EV charging is in progress as well as house batteries, I will report on the results of that test in due course.

admin

Thanks for testing this.

duplada Use Discharge in Schedule Set Off = 100% Max Inverter Rate

Not sure what you mean with 'Use Discharge in Schedule' set to Off? Are you talking about export schedules?

duplada

admin Not sure what you mean with 'Use Discharge in Schedule' set to Off? Are you talking about export schedules?

So below is how all of the Schedules we set regarding the Discharge Rate Toggle it was OFF. Therefore the Advanced Rates should not have applied the Export should have been @ 100%. When I checked the GE Logs my inverter was exporting at the Rate set in the New Rates not @ 100%.

admin

duplada Ah - thanks for that, so yeah that setting will disappear and be replaced with the dropdown.

Working on this now. 😉

~~The percentage readings on custom charge rates will be rated against the max specified in the new rate limits by the way. Happy to then iterate on that if we find it's not suitable.~~

Yeah, not sure that's as intuitive...

duplada

admin Yes leave it with you, you are correct its not easy to understand and remember what setting does what that's why having names for rates is better as you then know you are in the right place and have chosen the correct setting.

When you have finalised this do you think you could write it up or at least explain it to me and I will write it up.

admin

duplada Now available for users who've opted in, in version v0.5.1256.

See new Rate Presets page under Schedules, and ability to use these in Charge and Export schedules.

Let us know how you get on.

KristianS

Late to this party, as I have been busy. I have just seen my new configurable rates on the Advanced screen. I will do a GivEnergy system reset to factory defaults, set the value, save and then give it a quick Export and let you know.

KristianS

I can confirm that my desired Export rate is now being controlled by WW. Thank you. No more editing in multiple places to make sure I do not exceed my DNO or my desired rate.

duplada

Fantastic I will modify my Export Schedules with Rates tonight and test the charge tomorrow. I will report back with details.

duplada

So last night I had 2 schedules still to execute by the time you had released the new Rates Preset software version.

my Advanced Rate settings are as below

Prior to software release last night all my Export schedules were getting there power set to 82% as per the advanced settings above.

For my schedule that was to execute at 22:50 I created an new bespoke rate of Test 83% so that I could test that the correct rate was being applied.

I applied the Test 83% to my schedule and waited for it to execute.

The schedule executed on time and the correct power setting of 83 % was set.

I had one more Export schedule to execute at 01:39 and I left this with the Default Rate of 100% set

When this schedule executed I expected that the power setting in the portal command would be set to 100% but it wasn't it was set to the 82% Advanced Rate setting instead. I find this confusing and I am unsure why this should have happened can you please clarify.

admin

duplada Yeah, looks like a bug, thanks for testing and reporting, we'll get a fix out.

duplada

OK thank you let me know and I will retest.

admin

duplada Fixed in release 1260. UI glitch where if there was only one entry in the Rate Preset dropdown, you'd think it was set, but without saving it would not have been. As was the case with you.

Now shows a 'Choose rate preset..." if none has been selected.
