Single Battery Power Exchange

AC1 = IDLE / DC2 = PWR / DC3 = NET
 A novel example of DC-to-DC power conversion. This use case uses a single battery wired
identically and shared between the DC2 and DC3 ports. The net current measured and
multiplied by stack voltage reflects the efficiency of the Converter's DC-to-DC conversion.
 The PWR Control Method scaling factor is 10 Watts. Writing a DC2 power setpoint value of
500 will yield an output power level of 5 kW on DC2. This power is provided by DC3, which
is actively discharging DC2, while DC3 is actively charging the battery at approximately the
same rate, net of converter efficiency loses . Writing a DC2 power setpoint value of -500
reverses power flow direction on both ports yielding an output power level of 5 kW on DC3
net of efficiency losses.
NOTE: IPWR's name for this single-battery DC-to-DC power flow example is "net @ battery".

Dual Battery Power Exchange

AC1 = IDLE / DC2 = PWR / DC3 = NET
 This DC-to DC power conversion example uses two independent batteries connected to DC2
and DC3. Battery stack voltages may be dramatically different. However, note that battery
voltages <500 V will not allow full 30 kW transfers due to system DC current constraints.
 The PWR Control Method works identically to the single battery example above.
AC Microgrid – Using Single Battery
AC1 = FPWR / DC2 = IDLE / DC3 = NET
 This power flow example uses a 500 Vdc (or higher) battery connected to DC3.
 DC3's battery will supply power as demanded in real time to support and hold the AC
microgrid output at 480 Vac, despite variations in load.
 Connect a variable AC load bank to AC1 and use an external DC current probe to observe
DC3 current responding rapidly to support the AC microgrid's changing load demand.
 Configure the 30C3 as follows:
1. Disconnect from external AC grid, and provide 24 Vdc external power to unit.
2. Update Port 1 (AC1) registers.
a. Update register 'p1_control_method' to 0x0502 (FPWR).
b. Update register 'p1_voltage_setpt' to desired microgrid line-to-neutral voltage.
c. Update register 'p1_frequency_setpt' to microgrid frequency.
3. Update Port 3 (DC3) registers.
a. Update register 'p3_control_method' to 0x0001.
4. Start power flow by updating register 'user_start' to 1.
