The Conext SW has been designed to give you premium true sine wave power, ease of use, and outstanding reliability for your off-grid and power backup applications.
ConextSW-NA-OwnersGuide.book Page 3 Thursday, July 23, 2015 3:26 PM Key Features Key Features The Conext SW Inverter/Charger is a true sine wave inverter/charger that can be used for off-grid, backup, solar, and hybrid applications. The Conext SW Inverter/ Chargers are designed to operate with a wide variety of generators and are capable of operating in parallel with a generator for short durations to assist with starting large loads.
ConextSW-NA-OwnersGuide.book Page 4 Thursday, July 23, 2015 3:26 PM Introduction Key Features Explained Built-in Charge Formulas For the unit to perform at the highest level, the batteries must be charged correctly. The Conext SW has optimized algorithms for flooded, gel, and AGM batteries.
ConextSW-NA-OwnersGuide.book Page 5 Thursday, July 23, 2015 3:26 PM Basic Protection Features Multiple Unit Charging Two Conext SW Inverter/Chargers synchronize charging stages to ensure efficient charging of the battery bank. When a single unit transitions from bulk to absorption so does the other unit. In absorption, the two units must complete the absorption stage before transitioning to the next stage. Note that the two units do not load share when charging except during the bulk stage.
ConextSW-NA-OwnersGuide.book Page 6 Thursday, July 23, 2015 3:26 PM Introduction Grid-interactive and Other Features Load Shaving Load shaving (Load Shave) allows the Conext SW to support (or assist) the AC source in powering local loads during a defined window of time (LoadShaveStart and LoadShaveStop). See “Time-of-Use Metering” on page 1–7. It allows the inverter to control how much current can be drawn from the AC source.
ConextSW-NA-OwnersGuide.book Page 7 Thursday, July 23, 2015 3:26 PM Grid-interactive and Other Features NOTE: Current is regulated by placing a limit (Load Shave Amps) on the current of the AC source. Grid or Generator 10 A AC IN Conext SW 5A 15 A AC OUT AC Loads SCP DC Battery Bank Figure 1-2 Load Shaving in Action Time-of-Use Metering Utilities use time-of-use metering to set utility charges during peak usage hours and to impose a surcharge.
ConextSW-NA-OwnersGuide.book Page 8 Thursday, July 23, 2015 3:26 PM Introduction AC Support allows the Conext SW to support local loads by converting excess power from external DC sources connected to its battery bank. Examples of external DC sources are MPPT solar charge controllers. When local loads demand more energy from the external DC sources then extra current can be pulled in from the AC source as a last resort.
ConextSW-NA-OwnersGuide.book Page 9 Thursday, July 23, 2015 3:26 PM Grid-interactive and Other Features controlled by the MPPT charger so that they can control the state-of-charge of the batteries. AC power from the grid is utilized only when load demand exceeds power available from the MPPT charger for charging and supplying the loads.
