Microinverters and storeage batteries?

[Flyback]

Hi,
If you have several solar panels, each with a microinverter, how can you set it up so that only the electricity produced from the solar panels goes into the storage battery (ie no electricity from the grid goes into the storeage battery)?

How could it?, an inverter is only one way - unless you added a charger to it, making it a UPS.

Thanks, i mean assuming there is already a charger available to charge the battery from the mains. ie the battery already has a battery inverter/charger with it.

Also, may i ask, is there such thing as a module that contains all of a ...

1...charger for solar to battery
2....Inverter for battery to mains
3....inverter for solar to mains
4.....Solar MPPT optimiser
5...charger for mains to battery

...ie, all 5 in one unit?
