I live off grid with a stand alone solar system and 6kva backup generator. Only once have ever had to use the backup genset when a fuse blew in the system and I had to wait to get it replaced. The main thing is to adjust your lifestyle so you are running appliances like washing machines ,dryers etc when you are getting a full charge from the sun. Don't have stuff with a big power draw running at night.I only have limited appliances running like fridge ,light,TV and modem during the evening.These things draw 0.4kw. I have a monitoring system on the setup so I can tell exactly what is drawing the power. A kettle boiling will bump it to 2.4 kw so I use a kettle I can put on the stove during the evening. I live in Australia and we have weeks on end of 40c and over temps and I don't have an Aircon. My house is double insulated so consider insulation for cooling and heating. It's amazing how much it drops got inside temp down. Lots of things you can do if you're prepared to change your lifestyle a bit.
