Off-grid system for school

[JohnyWalter]

I have a project to design a 40KWp generator system for a school that doesn't have grid connection. They do not need storage, they are planning to relay on solar + generator I m kinda confused what type of inverter to use? I know that ongrid should be connected to a grid to synchronize with its frequency. But the fact that we do not need batteries make me think that the offgrid inverter is not a right decision. I m planning to use SMA. So what inverters are needed u think? Also it is expected that grid will be connected in a couple of years.
Thanks!

I believe you are going to need batteries, you need to invest more time researching pv system design..

A generator cannot start up fast enough to compensate for moving clouds and so the school will black out for a minute or 3. Sorry.

It will require batteries. At 40 Kw panel system will require a 19,200 pound battery as a matter of fact.
