AC-coupling
1.AC-coupling
In an AC-coupled system, a grid-tied PV inverter is connected to the output of SPF 3000T HVM-G2 and SPF 6000T HVM-
G2. PV power is first used to power the loads, then to charge the battery, and any excess PV power can be fed back to
the grid.
When the SPF 3000T HVM-G2 (SPF 6000T HVM-G2) is connected to the grid, this excess PV inverter power will
automatically be fed back to the grid.
NOTE:The output of grid PV inverter can only be connected to the HOT1-HOT2 output of the SPF 3000T HVM-G2 (SPF
6000T HVM-G2), but not HOT1-N and HOT2-N ,only be used in a single unit.
When the SPF 3000T HVM-G2 (SPF 6000T HVM-G2) is operating in inverter-mode, disconnected from its AC input, it will
create a local grid: a micro-grid. The PV Inverter will accept this micro-grid and will therefore operate even during a
black-out. The PV power can even be used to charge the batteries: when there is more PV power available than used by
the loads, the power will automatically run through the inverter in reverse direction and charge the batteries. It is
necessary to regulate that power to prevent overcharging the batteries as well as overloading the inverter/charger. This
is where 'frequency shifting' comes in to the picture, see next section.
Highlights:
（1）SPF 3000T HVM-G2 (SPF 6000T HVM-G2) can prevent feeding back PV power to grid.
（2）Systems with only a grid-tied PV inverter will fail when there is a grid black-out. A micro-grid system will continue
to operate, and even keep using solar power.
（3）Most brands of PV inverters can be used for these systems, they need to be setup to support frequency shifting,
often called the island-mode or micro-grid mode.
