start with EV charger + battery ( + gateway/ ATS )
Hello,
With off peak prices tumbling in the UK in April 2026, I should act.
(all the qualifiers because this is a global forum at a time of change!)
Eventually I would like solar and ASHP heat pump too. But funds don’t allow me to do everything. Considering what’s possible now.
Already have an EV, and house uses some 6-8KWh /day.
I would like a smart, integrated everything from a single brand; it needs to just work. Not keen on calling back the installer, who says one thing isn’t/ can’t be integrated with another; or mandatory firmware updates breaking something when I have different brands.
I start with EV charger.
Installer cost is lower overa if they do ”more” per visit; separate EV and battery will be more than EV charge, then battery.
So, need EV charge and battery.
I also want to work off grid if necessary.
So, now I need EV charge and battery and gateway/ transfer switch.
The next phase will include ASHP, then solar PV.
Givenergy offer everything in a single brand, but seem to have a poor and declining reputation.
TESLA offer everything, but the EV charging smarts are only for Tesla EVs. Also the other thing I can’t say in this sub. So Tesla is out.
that leaves…
Sigenergy
Fronius
Both are relatively expensive premium products, if course.
Anyone care to…
