Hypervolt Home 3 Pro and the Hypervolt Home 3.0 are now fully compatible with Charge Anytime

We've just got the hypervolt home 3 pro and charge anytime. 4 March 2025.

We have solar panels and a battery.

We need to use the 'battery safe mode ' function on the hypervolt.  How do we do this via the charge anytime app, as the charge anytime app has full control? 

Thanks 

Howdy ​@John Hamstead ,

If you’re using that setup, it’s actually better to let the Charger do basically everything as-is and just use the Charge Anytime app for anything it controls and the Hypervolt app for everything else. Having spoken to Hypervolt previously, they suggest leaving the modes alone if you’re using CA as the Charger will figure that stuff out for you.

If you still need a hand, have a chat with them!

Hi ​@Blastoise186 

Many thanks for replying,  that's what we've tried,  using the charge anytime app,  as it takes complete control anyway.  However,  when we charge using it,  it takes as much as it can from our solar battery,  which is exactly what we don't want. 

Been in touch with hypervolt,  and they say there's nothing they can do as the charge anytime app takes over. 

Pulling our hair out here,  don't want to empty our battery to charge the car. 

I see. Your next port of call is the Charge Anytime team on 0330 175 9678.

TBH it’s kinda not ideal to have a home battery and an EV at the same time anyway at the moment, regardless of how you set things up…

I wouldn’t recommend disabling Charge Anytime either - you’ll want to keep that enabled.

John, I’m working through exactly the same problem at the moment also.

Hypervolt did tell me that CA supports battery-safe mode, but I can’t see how its possible to enable that whilst under CA control.

There are potential options. One of them is to wire the CP and solar/battery CT clamp in a way that it can’t see the CP load. But that’s not an option in my case.

My system does have some not so perfect work-arounds whereby I can program it to prevent battery discharge in pre-programmed periods such as overnight when I charge the EV. Not great I know. Especially as better days result in more solar generation and house battery charging.

I’ve got the installer exploring options with the inverter manufacturer to see if its possible to have an extra CT clamp monitoring the CP load to see if they can automatically suspend battery discharge at those times. But that’s more wishful thinking than a solid expectation.

They are increasingly coming across this challenge, as more people get EVs. Many of those are also likely to adopt solar/battery home energy systems, so this problem is only going to grow. The manufacturers need to get their act together.

Does this advice help ​@John Hamstead? Let me know if you have any issues getting through to the team & I can give them a nudge.

 

How to get in contact with the Charge Anytime team

• Charge Anytime - 0330 175 9678 (Option 1 new customers/option 2 existing customers) 

• chargeanytime@ovo.com

This doesn't sound hopeful but thanks for your input. It sounds like OVO haven't fully tested the Hypervolt. I'm not an electrician and so some of your text went over my head. What does CP stand for?

I'm going to tackle the CA team again to see what can be done. I don't want to 'suspend' by battery overnight just so the EV can charge. 

CP is Charge Point (i.e your EV Hypervolt charger).

The problem is not an OVO issue. It exists for almost every system that has a CP+Solar/Battery. 

Your installer/electrician will understand about the CT clamp position and wiring the CP differently. But if your install is anything like mine its not an option anyway. This is a method some others have used and indeed Hypervolt also suggested to me when I discussed with them.

Yeah I don’t really want to suspend the battery overnight either, but I mentioned it as its an alternative until the manufacturers/designers come up with a permanent solution, hence why I have my installers discussing it. For me thats better than the EV discharging the house battery. It means I don’t get the benefit of my own power overnight, but you have to decide whats more preferable to you.

There isn’t an ideal solution at present because your battery will be seeing the EV charger as a load and hence doing what its intended to do. The fact its an EV load is irrelevant to the system. 

Just to add..Although I enquired to Hypervolt about battery-safe, it strikes me that’s not really a good alternative anyway. With my house battery now getting much more charge with the higher sun, it always going to have charge overnight. If the Hypervolt pauses EV charge because of battery-safe mode it would be in a never ending pause until the house battery has fully discharged. Also bear in mind for these type of features to work you need to make sure the Hypervolt has the 2nd CT clamp installed. It doesn’t get supplied as standard, so your installers would have needed to be aware of it.

Just an update to my previous posts.

I’ve tested another solution with the installers and so far it seems to be working, and its preventing the house battery discharging into the EV battery.

It also seems to avoid the need for any programming or pausing the house battery.

We have placed an additional CT clamp onto the CP circuit, but in the opposite direction, spliced that into the inverters main supply CT clamp. It has the effect of cancelling out the EV load in the inverters logic and hence prevents a battery-to-battery discharge.

It also doesn’t impact CA.

Progress! Thanks for posting that update ​@oho, it’ll help other community members with a similar issue 🙂

Hi,

Can’t say that I’ve fully tested this - not enough solar yet, but the way my system is set up (by OVO) seems to work mostly the way I want it.

The Hypervolt seems to take electricity straight from the meter junction and doesn’t go through the main consumer fuse box where the solar and battery are connected . If I look at the app for the battery which measures load, PV and battery state of charge I don’t see any figures for the EV charger. I’ve not tried to use the Hypervolt and solar to charge the battery, so don’t know if this function works .

I will keep an eye on it, but for the moment I don’t think the battery gets drained to charge the car.

Sorry to reply to my own comment, but pretty sure it’s working as described above. Kicked off a charge yesterday which started at 10pm, didn’t touch the battery.

Hi ​@Colingray83 that’s really interesting, thanks for letting us know! If you could keep us updated we’d appreciate it 😁

Cheers!

Hi,

so was a nice sunny day today and using Hypervolt was using solar to charge the car. Now whilst both the OVO app and the Hypervolt app tell you they’re using solar, it doesn’t seem to be recorded by either app as such. In fact, the OVO app marks it down as Smart Charge, this really should be marked as solar.

will need to check the OVO energy app tomorrow to see how it was recorded, ie have I been charged for the power or receiving rebate that I shouldn’t be getting.

Thanks ​@Colingray83 for the update, I’ll wait to hear back from you about this - if anything’s wrong I’ll feed back to our Product teams.

Cheers,

Ben

Hi ​@Ben_OVO 

in the OVO energy app, no electricity was being taken from the grid as expected during the day as it was really sunny. However in the Charge Anytime app it’s showing as a Smart Charge - from the data shown it’s not possible to tell that this came from solar energy. The same is true in the Hypervolt app.

if this is the data OVO are using, I might be given a rebate against electricity I haven’t actually taken from the grid. Might be worth an investigation.

Morning ​@Colingray83,

Thanks again for your detailed updates - much appreciated. I’m going to pass this up the chain within the Charge Anytime team. I’ll get back to you as soon as I have any news!

Cheers 😁

​@Colingray83 the Charge Anytime team may need to raise an internal ticket for this one. They’ve asked if you’d mind emailing them directly if that’s ok? Their email address is chargeanytime@ovo.com.

Hi,

update from the Charge Anytime team. 
 

The app doesn’t currently separate solar and grid charging, everything will show up as a Smart Charge.

there is some back end processing to ensure you don’t get charged and/or receive credit for non Anytime charging.

colin.

Hi ​@Colingray83, I hope you had a good weekend.

Thanks for this really useful update - very helpful to know, and I’m glad we got some answers that show there was nothing concerning going on! 

Cheers,

Ben

Hi Oho, can you confirm if you have both a Hypervolt and hybrid inverter? When my installers installed the Hypervolt, the manual clearly specified not to use a 2nd CT clamp if my solar has a hybrid inverter. Keen to know what your system looks like, if it’s working!

​@sanjoo  We do indeed have a Hybrid Inverter, its a LUX LXP6K.

The 2nd CT clamp is a necessity for supporting OVO CA otherwise there is no detection of solar rather than supply charging the EV (dependent how your Hypervolt has been wired I might add).

My point about the 3rd CT being spliced into the solution was not a requirement for the above, this element was to prevent the home energy battery from discharging into the EV, which is not what I wanted. There are also other ways of dealing with that issue.

Going back to the 2nd CT clamp, I am unable to find any indications in the manual stating it should not be used. In fact Hypervolt themselves advised me it should be used in this scenario.

https://support.hypervolt.co.uk/en/knowledge-base/home-battery-system-setup

If you are having problems with your system, if you describe them, we might be able to assist or provide some insight.

Hi again, see Hypervolt link that says do not install a 2nd CT if the house has a hybrid inverter: https://support.hypervolt.co.uk/en/knowledge-base/2nd-ct-installation-guide

my issue is exactly the same as yours I.e I don’t want my battery to discharge into the EV. At the moment when I charge at night for example, it draws 5kwh from my solar battery and only 2kwh from the grid and this is not favourable at all. My workaround at the moment is to increase the threshold of my battery to stop discharging completely during the charging session which also means that during these hours my house is also using grid power at standard rate!

I think that section of the Hypervolt manual very much depends on your system and how its setup. I’m not sure but if Hypervolt are referring to BatterySafe Mode, that doesn’t work when the Hypervolt is under OVO control. Are you using OVO CA and is it the Hypervolt or your EV that is integrated? Mine is the Hypervolt.

If you dont have the 2nd CT, OVO can’t detect (via the Hypervolt) the home energy supply, only the grid supply. Also without that I was unable to benefit from solar EV charging (which requires a spare 1.4kw+ from solar) Again I must caveat this as it depends on how its all wired and where the CT clamps are positioned.

The problem of your home battery discharging into the EV is a common issue present with most systems. Some workarounds require you to wire the Hypervolt grid supply before the main inverter CT clamp (via a Henley block in the meter cupboard) or move the inverter CT so that it doesn’t detect the Hypervolt EV load. None of these were an option for me as I have the Hypervolt via a 2nd CU in a detached garage.

I looked at various alternatives including what you are having to do with battery thresholds. I even discussed with the inverter manufacturer about enhancing their design with an additional CP CT clamp. I wanted it all to be automatic and still get the full benefit 24/7 from the home battery (but not for EV). Anyway my installer came up with a very easy workaround with the additional CT clamp spliced into the inverters CT link as explained in an earlier post. The idea is that it prevents the inverter seeing the CP/EV load and hence stops the battery-battery discharge. This has worked perfectly since it was setup.

Thanks for your detailed response. I have exactly the same set-up as you. I have a submain in a detached garage which the Hypervolt is wired to. 
your solution seems to be working and might be the way to go.

Is it possible to share details of your installer? Perhaps they might be able to advise if I send pictures of my setup.

If you check towards the end of the page in the link I sent, it is quite clearly advising against a 2nd CT for hybrid inverters, irrespective of installation and my Hypervolt didn’t come with a 2nd CT.

my Volvo is connected to the Hypervolt (again a must by OVO is you have Hypervolt and solar), so same as urs
