This inverter/charger is a split-phase pure sine wave inverter, adaptive battery charger, and transfer relay for reliable AC power. With a 4200-watt capacity and the ability to connect to a standard household panel, this inverter/charger is easily paired with a 48V battery bank and a solar system. These inverter/chargers cannot be paralleled.

The AC input can be customized by users to set desired voltage and frequency parameters. This charger allows you to easily link a 48V MPPT solar charge controller directly to the EVO by utilizing the external DC Input with a capacity of 100 Amps.

The battery charger offers a 3 or 4-stage charging process, including Equalization, which requires manual initiation. The following stages of charging are determined based on the battery’s condition rather than adhering to preset time intervals for Absorption and Float. When it comes to the transfer switch there is virtually no downtime during the transition from the Inverter to the Grid. The transfer time is less than 18 milliseconds when switching from the Grid to the Inverter. These transfer times allow for a reliable uninterruptible power supply (UPS).

  • 4 stage 48 VDC, 17A charger
  • 200amp transfer switch
  • Soft Start Surge Protection
  • Neutral to Ground Bond Switching Relay for grounding compliance
