The generator shall be an AC home standby generator that is hardwired. Portable and/or manual start generators are not supported. – Savant recommends the generator has provisions for 2-wire start/stop capability. The SPS system uses these control wires to START/STOP the generator based off SPS battery state of charge (SOC). -

2. Generator to GEN Terminal Installation Installation steps for a Generator to GEN Terminal design include physical wiring, configuration with the Savant Power Storage app, and configuration using the Savant Power & Light app or RacePoint Blueprint software. When off grid, a Generator to GEN Terminal installation allows the batteries of the SPS system to be charged via a generator in the following manner: When an individual battery stack discharges and reaches its generator starting state of charge (determined by the Savant Power Storage app. -
Page 5: Physical Installation
2.1. Physical Installation Follow the instructions below to install a generator with an existing Savant Power Storage system. See Appendix: Generator to GEN Terminal Wiring Diagram for wiring example. Connect the AC output and ground terminal of the generator into all SPS GEN terminals (L1/L2/N/G). This can be done either directly onto the SPS GEN terminals or through a Generator Combiner Breaker Panel for a parallel SPS configuration. -

2.2. Generator to GEN Terminal Savant Power Storage App Setup Use the Savant Power Storage (SPS) App to program the AUTO-START/STOP parameters of the connected generator for each SPS system. From the Settings menu in the SPS App, navigate to Connected Power Sources and access the Generator Port page to configure the following fields: Select Generator mode. -
Page 7: Generator To Grid Terminal (Upstream Ats)
Installation steps for a Generator to GRID Terminal design include physical wiring, configuration with the Savant Power Storage app, and configuration using either Blueprint or the Savant Power & Light app. Once configuration has been completed in the Savant Power Storage app, additional configuration is required to properly automate generator functionality. -
Page 8: Physical Installation
3.1. Physical Installation Follow the instructions below to install a generator with an existing Savant Power Storage system. See Appendix: Generator to GRID Terminal Wiring Diagram for wiring example. Connect the Utility Power Source onto the Normal terminal of the generator ATS (L1/L2/N/G). -

Additional configuration is required to properly automate generator functionality once configuration in the Savant Power Storage app is completed. Only one configuration tool is needed. (RacePoint Blueprint OR Savant Power & Light app.) If the Savant Power & Light app is the configuration tool of choice, follow the instructions below. - Page 11 Select Battery Storage then tap Next. Select Savant Power Storage 20 or Savant Power Storage 50 as the power source profile then tap Next. Determine the configuration from the options below and continue onto steps: – No external generator configured. (There is no generator sitting on an upstream ATS). Continue to step –...
