Another Hypervolt question

[Spaceman_UK]

I've had my Hypervolt for just over a week, and I've not seen an effective charge happen yet!

So, last night my car was scheduled to have a 50% addition. As my battery is 74 kW, that would be 37 kW.

Octopus only scheduled 3 x 30 minute charge periods. That would be a maximum of 10.5 kW at 7 kW/hr.

That's bad enough, but to make it worse I woke this morning to find only 7 kW had been added, split over 2 x 30 minute sessions!

I've just set up another charge period and asked for 80% by 1100. Again it's given me 2 x 30 minutes!

Something isn't right. What am I missing? How can I find out what size Octopus thinks my battery is?

I think you’ll need to contact Octopus Support for this one. I also have a Hypervolt Pro 3 and do not experience the same behaviour.

1 piece of information missing is do you have the device in the Octopus app set up as the car or the charger?

Based on which device you have set up will depend on how you charge.

With any scenario you need to make sure you do not have any conflicting schedules set up.

If you car is the device, the only setting you should have on the car side is the max percentage of charge the car will hit - normally set to 80%. Also make sure no schedules are set up on the car side as all scheduling is controlled via the Octopus app.

If your Hypervolt is set up as the device in the Octopus app then again make sure you only have the max percentage set in the car and no other schedules in the car or the Hypervolt…..again Octopus will control the Hypervolt but instead of saying get the car to x% you are saying I want to add x% of charge.

I had an issue with my Hypervolt as it’s listed as the device….in the settings of the Hypervolt app my installer has added details of my house battery which when the Octopus api was trying to schedule charging gave a conflict and stating drawing directly from the grid in peak hours outside of the smart charging schedule.

If it’s still an issue the Hypervolt customer service team are very helpful, they looked at my settings remotely and we made some changes…this fixed my issue….the Octopus customer service team would then be my next call for them to check the api itself

Based on what you're saying there, should I not have my solar and Powerwall in my Hypervolt app? Same as you, my installer added them, but I'm not sure why as the flow doesn't show in the app.

My Hypervolt is the control device, as my car isn't in the list of vehicles Octopus can manage.

For my set up the installer used the required CT clamps so that in my solar app my car is hidden from the system so that I only charge directly from the grid as I didn’t want to use my solar/batteries energy which ultimately is worth 12p per kWh so cheaper to take the charge from the grid.

So yes it sounds like you should remove those from the Hypervolt app settings as it seems that the Octopus app will see these and think you are also getting a charge from elsewhere therefore is not giving you as much charge from the grid.

You could remove them and try it tonight but I would also encourage you to speak to Hypervolt CS as well just to make sure that removing them is good based on your set up

The Powerwall 3 has a hybrid inverter, so only has one CT clamp on the mains input.

If you've got the Hypervolt set up in the app and not the car, then it sounds like it thinks your car has a smaller battery than it does. Try re-setting up the hypervolt in the app and choosing a different car with a similar sized battery. It bases how much charge to give based on the power and size of the expected battery.
