  • Page 4: Introduction

    Introduction General Feature The “Stackable Inverter” is a 3 in 1 multi-function module unit – True Sine Wave Inverter built in programmable Battery Charger and Auto Transfer Switch (ATS). Besides these primary functions, however, the Stackable Inverter has several advanced features that provide a range of new applications as outlined below: Uninterrupted Power deliver In the event of a grid failure, or shore or generator power being disconnected, the inverter...
  • Page 5 Battery Charger Adaptive 4-stage charge characteristic: Bulk-Absorption-Float-Equalize The “Stackable Inverter” features a microprocessor controlled “adaptive” battery management system that can be preset to suit different types of batteries. The “adaptive” feature will automatically optimize the process relative to the way the battery is being used. The right amount of charge: Variable Absorption Time When only shallow discharges occur (a yacht connected to shore power for example), the absorption time is kept in order to prevent overcharging of the battery.
  • Page 6 Battery Voltage Sense In order to compensate for voltage loss due to cable resistance, the “Stackable Inverter” is provided with a voltage sense facility so that the battery always receives the correct charge voltage. Extensional Solar Charger Stackable Inverter also provides the availability of up to 10 sets of Solar Charger, PM SCC 45A or PM SCC 60A (optional) to be used with solar panel to charge the battery.

  • Page 66 disabled (B2-06=0) When the AC IN voltage drops due to the increasing charge current, the AC CHARGER will take care that the voltage does not drop below this level. B2-02=B2-01+offset voltage For example: PM-1500SI-122, when B2-01=180V, B2-02=187V, offset voltage=7V (187-180), B2-02 will automatically go to 197V(190+7) after B2-01 is changed to 190V. B2-03: AC IN High Connect This setting forms a pair with AC IN High Disconnect (B2-04).
  • Page 67 Setting Function By disabling AC IN waveform check, AC IN Low Disconnect (B2-01) is ignored. When the load current is B2-06=0 higher 1.5 times than AC In Current Limit (B2-05), this is (Ignore) used to prevent unnecessary switching to INVERTER due to voltage drop when a high load is connected.
  • Page 68 The effective AC input current limit depends on the load history. When the load is lower than the AC IN Current Limit (B2-05), the effective AC input current limit is also lower but slightly above the load. B2-09=1 When the load increase, the effective current limit also increases with a delay.

  • Page 70 B2-20: MODE3: ACIN Current Lmt Use constant B2-20 to set the set the specific maximum AC input current in MODE 3. This value is very important for both battery charger and inverter output power assist. When using constant B2-20, the values determine the actual AC current limit. B2-21: MODE4: ACIN Current Lmt Use constant B2-21 to set the set the specific maximum AC input current in MODE 4.

This setting can be disabled because it does not always indicate a problem when the bulk phase lasts very long. The charge current can be very low due to limited AC input current and/or AC loads.

U1-02: AC IN Current Use U1-02 to monitor the current value of AC IN power in unit of 0.1A. U1-03: AC OUT Voltage Use constant U1-03 to monitor AC OUT voltage value in unit of 0.1V.
  • Page 86 U1-09: Operation Status There are 12 digits to account for each operation status. Please see NOTE 1 in Chapter 5. U1-10: Aux-Relay Status Use constant U1-10 to monitor the ON/OFF status of 3 sets of Aux-Relay (RY1, RY2, RY3). Please see NOTE 2 in Chapter 5. U1-11: Elapsed Time Use constant U1-11 to monitor the elapsed time after power ON (O2-03=0) or after RUN (O2-03=1) in unit of 1 hour.
  • Page 87 U1-17: Solar Supply Power Use constant U1-17 to monitor the solar supply power value in unit of 1W. U1-18: Solar Amp-Hours Use constant U1-18 to monitor solar Amp-Hours value in unit of 1AH. U1-19: Solar Total Amp-Hours Use constant U1-19 to monitor solar total Amp-Hours value in unit of 1AH.

  • Page 88 U2-06: AC OUT Current Use constant U2-06 to monitor the AC output current value in unit of 0.1A when the current fault occurs. U2-07: Battery Voltage Use constant U2-07 to monitor the battery voltage value in unit of 0.1V when the current fault occurs.
  • Page 89 U2-14: Solar Charger Status Use constant U2-14 to monitor solar charger status when the current fault occurs. This constant is only visible when extension port is connected to solar module. U2-15: Solar Charge Current Use constant U2-15 to monitor the solar charge current value in unit of 0.1A when the current fault occurs.
  • Page 90 U3-03: Fault Message 3 Use constant U3-03 to monitor the most recent third fault stored in the software. U3-04: Fault Message 4 Use constant U3-04 to monitor the most recent fourth fault stored in the software. U3-05: Elapsed Time 1 Use constant U3-05 to monitor the elapsed time before the latest fault occurs.
