A greenfield plantation site has no grid to fall back on, so the storage has to carry the site through two full days on its own.
An off-grid storage system giving a greenfield plantation site 48 hours of battery backup, charged by its own solar array.
Off-grid plant power backup and telecom tower supply
The site runs for two full days on stored power with no grid connection at all.
Forty-eight hours is the figure that makes a greenfield plantation workable. It covers a run of overcast weather without anyone rationing supply or making a trip up an access road, which is the difference between a system that is trusted and one that is worked around.
Off-grid sizing is a different exercise from backup sizing. There is no grid to come back, so the battery is the supply and it must cover consecutive days of poor generation, not the hours of an outage. Forty-eight hours is the figure that makes a site workable without anyone rationing supply.

Enough to cover consecutive days of poor generation. With no grid to fall back on, the storage is the supply rather than the backup, so it is sized on the worst month of the year rather than on an average day.
Yes, where the array is sized for the worst month and the battery for the days of autonomy required. The hybrid inverter is what holds the supply steady as the load changes through the day.
The battery carries the site until generation returns, which is what the autonomy figure is for. Sites that cannot tolerate any interruption at all usually keep a generator as a second layer, started rarely rather than run daily.
