EV general discussion

Looks like you bolted a toilet bowl to the front of your house

I'm not too fussed about the looks, I'll have a 10kW AC unit strapped the side of my house soon so it ain't going to be pretty.

The solar modes are basically the same.

It's not something I'll use really while export is so high, but if that changes then it could make sense to self-use solar to charge up the car.
 
I meant between the Zappi and hypervolt. They have the same 2 basic modes which you need.

One is only put solar into the car and it will turn off is excess solar goes below the 1.4kw minimum.

The other is maintains a minimum of 1.4kw going to the car and can use some grid electricity when the clouds come over.


The main advantage of the zappi is the integration with their Eddi hot water diverter. The downside is the looks and I think it’s more expensive. Although they do have the new Zappi Glo now.

Both are on IOG.

Edit: Zappi also supports wireless CTs via the Havi device.

Doing some AI research based on what you said there and I think the Zappi would be a better option due to our hybrid inverter.

2. Battery Inverter Compatibility
The type of solar inverter you have heavily influences the ease of installation.
  • The Zappi Approach: It handles both AC-coupled (separate battery and solar inverters) and DC-coupled (hybrid inverters) systems with ease. It allows the installer to position CT clamps or configure wireless settings so that the car, house, and battery never compete for power.
  • The Hypervolt Challenge: Hypervolt does not support a second CT clamp if you have a hybrid inverter (where the solar panels and battery share the same box). Because a hybrid inverter mixes solar and battery power before sending it to the house, the Hypervolt cannot physically differentiate between "free solar" and "stored battery power" using hardware. Instead, it relies on a software wizard in the app to prevent battery drain
 
That’s incorrect on both counts. Got to love AI slop.

If you have a hybrid inverter, a CT clamp can’t tell if what’s coming from your inverter is battery or solar. The 2nd CT clamp for ‘battery safe modes’ only works on AC coupled batteries.

Hypervolt also supports a 2nd CT clamp.

Edit: neither matters if the inverter is blinded to the charger.

Ouch on that repair cost, luckily you got the goodwill bit so a fair amount cheaper.
Battery check doesn't seem to be too bad, but what sort of charging were you carrying out?
More AC charging at home and only to 80%, or lots of rapid DC charging to 80%+.
Be interesting to know to see if that has any effect.

Owned the car since 7000 miles - 99% home charging to 90% 99% of the time.




Much better than Sex Panther.
 
From the charger options my understand is the Hyperbolt is compatible with IOG and the Zappi isn't, but the Zappi has better solar compatible modes.
The zappi was supported by IOG before the hypervolt . am sure hypervolt will be fine but feature wise the zappi is just as well supported.

1 feature which may be a decider or may not matter at all.
if you want a tethered charge point

the zappi comes as standard with a 6.5m cable

the hypervolt only comes with 5m. BUT as an upgrade can be specced with 7.5m or 10m cable.

Just to follow this up, the local MB dealership took the car in this week and diagnosed a thermal cutout switch in the charging socket as knackered, so the car was thinking it was overheating constantly and not allowing the charge.

Total cost to replace - £2200.

This is plainly ridiculous, and without even asking they’d gone to MB asking for a goodwill gesture due to it being a 72 plate on 27k miles, and it brought the price down to £850. Drive a Mercedes, pay Mercedes prices!

Oooff! When Tesla changed the charge port assembly on my car, the part was £220 and 1 hours labour.

It was done under warranty but I think labour rates are about £250 an hour these days.

Edit: just checked the parts catalogue, £279+VAT for the charge port assembly plus high voltage cable to the battery.


The motorised flap is a separate part but only £117+VAT

I wonder if EVs with solar panel roofs will ever make a comeback
I think nissan and Hyundai are releasing such a car soon iirc.

no idea if the aptera will ever be released in the UK... but to be fair that is less a genuine car and more a rich person's play thing imo

IF they did however it would actually be a car worthy of the phrase "self charging" unlike the lies spouted by companies selling petrol hybrids

Would’ve been nice, but Mercedes gonna Mercedes! :D

Only if you could leave it for a week in the Middle Eastern desert to charge. Rather have my sunroof…

If the Inverter is blind to the EV charger how does the EV charger use solar?
 
Because the EV charger isn’t blinded to the excess solar flowing to the grid.

You’ll place the charger CT clamp next to the meter so it monitors the full installation.

ah that makes sense, it sees the excess (export) happening and the EV charger can tap into that.

So would you say go for Hyperbolt?
 
C-HR+ was alright - it felt a lot more like a standard car compared to the Tesla - as obvious/silly as that may sound.

Interior space was noticeably less, despite seeming about the same size exterior. Quality did feel about the same or dare I say a bit less than the Tesla too.

Speaking to the salesmen did highlight its more advisable to put a lower deposit on the car, and pay the monthly’s out of the BMW sale, rather than put 13k down (the max Toyota would do for that car).

I prefer the Tesla, the misses prefers the Toyota - she says it seemed more normal and less daunting.

She chose were we moved house - so I feel it’s fair I get dibs on this choice ;)

It’s totally personal preference, both will do what you want.

The way I see it is you are trading off looks (hypervolt) vs the ability to add a hot water diverter which syncs directly with the charger (Eddi).

If the way it looks is something which is a big deal, consider an Anderson charger. Sure it’s more expensive but it’s got a far more classy look than the hypervolt. It’s IOG and solar capable.

1st weekend of the school holidays and the trip to Bournemouth was relatively quiet. I popped into instavolt Winchester and only about 7 cars charging
Considering this site is cheaper than other installs (65p before 8pm) i'm surprised it wasn't busier

Mine is almost all the same charging type now - 7kw both at home and at work and always to 100%.
First couple of years was 50/50 home charging and fast charging.

Car is booked in to have an update on the possibility of the rear doors opening (known issue) when driving. Can't get me in until middle of September and need the car for 2 days!!
Told them to carry out the MOT as well before it goes back, but will also ask them to check on battery health at the same time.
