Looks like you bolted a toilet bowl to the front of your house
The solar modes are basically the same.
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.
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
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.
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.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.
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!
I think nissan and Hyundai are releasing such a car soon iirc.I wonder if EVs with solar panel roofs will ever make a comeback
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

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.
Comeback? The leaf one was a 60W panel to power the cabin fan. That’s all.I wonder if EVs with solar panel roofs will ever make a comeback

It’s totally personal preference, both will do what you want.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?
Mine is almost all the same charging type now - 7kw both at home and at work and always to 100%.Owned the car since 7000 miles - 99% home charging to 90% 99% of the time.
Much better than Sex Panther.
