Has anyone had one installed instead of the backup gateways

So i have agreed with a local installer for solar, batteries and ev charger.

I originally got quote for a hypervolt but he did mention sigenergy have a charger and from a quick google I see they have a new one released or soon to be.

Would I be sensible getting sigenergy as I see it does reverse charging or keeping hypervolt or even a different brand?

Been told sigenergy be about 175 less not sure if it old model but it lacks some features of hypervolt intelligence but it would mean 1 single app for my whole setup and prob speak better as whole system.

Anyone got any views on this how sigenergy integration with other ev chargers went, obviously wont be charging from my battery but I guess worried it just decide to discharge into my car lol

We have a new sigenstor 18kWh battery with DC charger. Together with our solar panels, the battery is doing fine, it gets us through the nights comfortably. The AI even finished learning and now dumps the excess batterij charge on the grid when the prices are highest. But the DC charger has been giving me a headache.

What I expected was: plug in a car, set departure time, forget. The system would then charge the car with the cheapest electricity available, be it surplus solar, surplus battery charge or cheap night power of the grid.

But it has not been working at all with our ID.3. Only when we do a fast charge will it work. Pv surplus mode stops charging within a minute. The pv surplus charging does work on our Audi e-tron. So I think it's a communication fault between the Sigenergy and Volkswagen.

But the plug and forget with the help of the AI mode has not worked on either vehicles. It just fails every time, maybe because it does not start charging immediately the cars just disconnect?

I'm really regretting going for the DC charger. I wanted to make a future proof purchase. But it's barely doing the basic task of charging.

I’m trying to get the home assistant plug in working with my EVAC charger. I have reached out to my installer about setting up modbus for me but they haven’t replied. Has anyone set themselves up as an installer just to be able to change their own settings? I’m not sure why sigenergy hides them behind the installer config surely just an advanced menu would be ok.
