If you have solar power with a battery installed, and a power cut occurs on the electricity grid in the summer, normally your battery will be fully charged due to all that surplus solar power you get in the summer months. So you can easily switch over to battery backup and carry on as if no power cut had occurred. The winter is quite a different story. Even on a sunny day in mid-winter, you will get no more than four hours of solar battery charge at most around the midday period. That power will soon be used up on the winter needs of your household, so the likelihood is, if a power cut does occur in the winter, there will be no power left in the battery to switch over to.
It's good to get into the habit of keeping an eye on the weather forecast, in particular any yellow, orange or red alerts for high wind. When an alert is given out, change the settings of your solar to charge the battery from the mains power supply from four hours before the winds are forecast, right up until their forecasted ending. This will ensure the battery is maintained at full power ready for any emergency. You won't be wasting any money because, as soon as the stormy weather has passed over and you reset your solar not to charge the battery continuously, the power in the battery will flow back into your house in preference to purchasing more power from the mains.
