I use about 5 or 6 kWhr a day year round, and a Tesla powerwall has 13.5. It could be a good investment for keepinhg the GCH going, if nothing else!

I use 20-30kWh a day and can store 11kWh. In summer and sunny shoulder-month days I can get through on solar/batteries with modest energy savings as appropriate. Winter? I’d struggle bigtime, particularly as power cuts tend to occur in the evening when my batteries are depleted this time of year.

Another complication is “changeover”. I’d have to go outside, flip the DP isolator, come in and go upstairs to the room below the inverter, connect my phone to the inverter’s own wifi, set the inverter to “off grid” mode. I’d then have to notice the power was back on and reverse the process. Hardly seems worth it for most outages.

I could connect a 2nd CU to the “UPS” terminals of my inverter and connect that to smaller, essential, loads. I could also reserve battery capacity for use only when power is out. However this seems like a lot of effort to go to for a situation that just doesn’t happen where I live (10 years and counting since the last outage).

Those with ‘vehicle-to-load’ could be laughing (Ioniq-5 or Kia EV-6), if the battery was sufficiently charged before the power cuts. Just pop out to the nearest working fast charger and maybe back at home before the ‘living cocoon’ had cooled off. 3kW should be more than adequate in those situations. I would have to make do with my 3kW diesel generator)

I've got a battery but got it before the back-up gateway unit was available and its just sat there doing nothing for the past nearly 4 days (Friday 3pm till today at 1:30pm) :cry:
Glad for having the wood stove, Tilly lamp, little portable gas ring and some other battery lights.
Got fed up and managed to hire a diesel generator yesterday to get power and get back normality (you don't realise how much you'd miss it till it's not there).
Feel sorry for those still waiting to be reconnected.

I finally got connected an hour ago. My battery grand plan would have saved some heart ache but unfortunately I'm waiting for the mortgage money to land so its not actioned yet. Turns out freezer cover in the insurance policy is worth **** all. The excess more than wipes it out. Almost pointless having it in the paperwork.

I hope the remaining ones without power get it soon. Thankfully its a bit warmer right now. Its been a stirling job being done by the the power teams. Its been horrible working conditions.
