I'd love to bite but I already have my own solar setup. Heat added (edited)
I've got 4kWp of solar panels/hybrid solis inverter being installed in the next month. I was putting off batteries until later, as it didn't seem cost effective going through the installer.
Someone told me about this company and thought I'd go for it. Was torn between this and their 15kWh solar battery (other deal). Think this is more suited for me at the moment.
With this you would wire to your home and charge at night on cheap electric and then run your home (3 bed house) on it during the day?
I'm assuming an electrician would need to wire it in?
When the battery runs out, your home would continue to use mains electric as normal?
or is this a product that charges purely on dc solar and then discharges it through your solar inverter to your home at night?
The inverter will monitor home electrical usage via a CT clamp and will discharge the amount of energy needed from the batteries into the home and load match the demand.
So yes, you can force charge these batteries with cheap overnight energy like I do at 7.5p/kWh which is roughly 3-4 times cheaper than the standard electrical rate.
Couple that with some solar panels connected to the hybrid inverter (solar panels are now at an all time low price) and you can be self sufficient for a good proportion of the year if you have a decent sized solar system.
I have 14 x 400w panels and produce roughly 5500kWh every year.
I also get paid 15p/kWh for any electric I export to the gird by my energy company.
It's a no brainer in my eyes if you can afford the few thousand pounds to install it. Your looking at roughly a 6-10 year payback depending on your situation and system setup.
Ignore 90% of what you read on this deals comments, most posters ain't got a clue.
And if an electrician is needed to install it all I assume you can just add a second one on top of this one yourself at least? Since they can be daisy chained and work as one. Might be worth trying 1 out at first and then getting another if needed, or get 2 for now and add another one yourself, etc.
