Pv + Battery Sum To Grid; Battery Charging From Pv And/Or Grid - Ideal Power Stabiliti Series Quick Start Manual

c. Update register 'pv_stop_time' to appropriate stop time window (in minutes).
Update Port 3 (DC3) registers.
3.
a. Update register 'p2_control_method' to 0x0001 for NET method.
Start power flow by updating register 'user_start' to 1.
4.
a. Note if available PV resource is < 15kW, the battery will contribute as necessary to
ensure that 15kW is exported to the grid.
b. Note if available PV resource is > 15kW, 15kW is exported to the grid and any
excess power from the PV will be directed to port DC3, charging the battery.
Run for desired time and stop power flow by updating register 'user_stop' to 1.

PV + Battery Sum to Grid

AC1 = NET / DC2 = MPPT / DC3 = - PWR
 Changing the sign on the above example results in a constant discharge of the battery to the
grid summed with whatever energy is available from the PV array.
 If DC2 is set to the IDLE Control Method or its target setpoint is programmed to "0", available
PV energy is exported to the grid, and the system behaves as a PV Inverter.
 Alternatively, setting DC3 to the IDLE Control Method disables the PV power effectively
creating a two-port Battery Converter.
NOTE: The DC Constant Current Control Method (DCA) may be an appropriate substitute for
the Power Method when applied to the DC3 Port.

Battery Charging from PV and/or Grid

AC1 = NET / DC2 = MPPT / DC3 = PWR
 Unlike the Demand Management/PV Firming flow example, which often subjects the battery
to highly variable and bidirectional power flows, this "battery friendly" configuration always
charges the battery at a fixed rate: +300 setpoint on DC3 = 3 kW charge.
 When available PV energy exceeds the commanded charge level, DC2 satisfies the DC3
charge requirement and excess power is exported to the grid.
NOTE: If available PV energy cannot satisfy the DC2 charge level, AC1 will import the power
necessary to satisfy DC3's 3 kW charge requirement by charging the battery from PV and grid
at the same time.
Use the use cases described above as a starting reference for other desired applications of the
30C and 30C3. Contact support@idealpower.com, should you have any questions about the
use of Control Methods.
