Considerations for DIY battery backup on grid tie system?
If you go with Enphase, you can install their battery later on easily. If you go with SMA (my recommendation), their battery can easily be added later also. Tesla Power walls can be added to ANY grid tied PV system. There are plenty of other battery systems that will work with any grid tied PV system as well.

This subsidy in Hong Kong is calculated based on the total generation after the inverter, called Feed-in-Tariff (FiT). The subsidy will calculate the final renewable generated export to the grid in Macau. The subsidised price in Hong Kong is 2.5 HKD/kWh, while the subsidised price in Macau is 2.8 MOP/kWh (equivalent to about 2.716 HKD/kWh).

AC Coupling: Adding Batteries to a Grid Tie Solar System
The main reason grid tie solar systems don''t provide power when your utility is down is for safety. Electrical codes require that when grid power goes out, a power inverter must automatically shut off. Once grid power is restored, your battery-based inverter shuts down and your grid tie inverter reconnects to the grid, powering your

I was wondering about anti islanding design. Using grid tie inverters is usually the best choice when not investing in batteries, but suppose you have batteries and want the confort of grid tie AND get uninterruptible power in case of mains failure ? if I understand well the current state of design and regulations for grid tie inverters is that anti islanding is compulsory.
Grid-tied with battery backup suggestions : r/SolarDIY
In grid-tie mode, your battery inverter is disconnected from your distribution panel but one of the breakers is charging the battery bank. If you want to go off-grid, you use the transfer switch to disconnect the utility and connect the battery inverter into your distribution panel to get the lights back on. This is the old-school way of doing it.
