Getting sigenergy, solar and ev charger installed but which charger?

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

Aberdeenshire south West facing

Had a company around to quote panel and battery. My house is south West facing but the roof due dorma is not ideal.

I have had quote through just wondering what you think. It would cover 3800 kwh a year and I roughly use 4200

System Specifications:

Panels: 11 x DMEGC 450W panels (4.95 kW system size total).

Orientation/Layout: Split array — 7 panels on a 40° tilt and 4 panels on a 20° tilt.

Inverter: Sigenergy SigenStor EC 5.0SP single-phase energy controller.

Battery: Sigenergy SigenStor BAT 6.0 (6.02 kWh capacity).

Cost £11442.10

7 panels will be on my main roof and the 4 panel would be on my garage roof

I am interested in kitting out as much as my roof in solar panels with batteries as I can manage.

Mainly to run my 4 bed house with 2 kids and 2 adults but I am at early stages of looking into electric cars as well.

Now I fully own my house it faces south/west and other than one bedroom having a peak it unobstructed and at 43 I dont plan to move again.

Are Home Energy Scotland doing any loans? I know there no grants but it be easier stomach the cost with a low/0% intrest loan.

Also what are best panels inverter and battery to look at to maximise storage and generation. I probably fit maybe max 12 panels on one side possibly
