For an economical PV system, with zero-feed in tariff, for a family home, with no one at home during the day time, the best setup option would be:
(some components might be in another)
1) PV, batteries, charge controller, inverter
2) PV, MPP tracker, batteries, charge controller, inverter
3) PV, MPP tracker, batteries, charge controller, inverter, generator
4) PV, MPP tracker, charge controller, inverter
5) PV, MPP tracker, inverter, generator
I think the components being in another would be the MPP tracker being in the inverter. The system has zero-feed in tariff, but it's tied to the grid.
These were the 5 options I was given. I would use PV, MPP tracker, inverter and generator.
If the system is tied to the grid anything with batteries seems like a waste. That leaves only option 4) and 5). Option 4) has a charge controller, which is used to limit the amount of current flowing into and out of a battery, and there is no battery in Option 4), so I wouldn't choose that one either.
