I have an Ecoflow Delta Max 2000 along with 2 x Ecoflow Delta Max Smart batteries giving me 6kW of storage. With 2 x 400W solar panels the system provided around half my electricity for 6 months last year, running the fridge, freezer, washing machine, microwave, breadmaker, miscellaneous charging jobs (phone, iPad, LED lanterns, etc.). As it is doing now as we "speak".
I also have a Jackery Explorer 1000 with 2 x 100W panels. This generally powers the TV, video, satbox, and occasionally one or other of the PCs during those same 6 months. Also misc. charging jobs. The panels aren't waterproof so, if necessary, I occasionally charge it from the Ecoflow. Also portable for camping!
Expensive setup, but it saves me a few bob even though, for me, there is no break-even / payback point. It's comfortable knowing that I have a useful backup when things go awry. I also have an old Honda 2500 petrol generator, which could be called into action if necessary, albeit not connected into the house system (yet). I have some Aspen Long Life Fuel for this, which has a life of 5 years. Expensive, but better than petrol sitting there in the genny, going off...'til you need it!
