Tigo Energy Storage Hybrid Inverter TSI-3.8K-US 3800W Ethernet/Wifi

Tigo Energy TSI-3.8K-US storage hybrid inverter has a nominal output of 3,800W and a PV input as high as 7,600W. It can be configured as solar-only to export energy to the utility grid or in hybrid mode when paired with Tigo’s EI battery to offer energy storage and backup power. Tigo EI inverters come in a NEMA 4x IP65-rated enclosure and feature integrated CCA and RSS capabilities. TSI models come with one TAP and E-Stop button.

The inverter will seamlessly communicate with the TS4-A-O or TS4-A-F modules to optimize solar production (optimization module only), monitor individual solar panel data, and provide Rapid Shut Down compliance.

When a complete energy storage solution is desired, add Tigo’s EI Battery to the system to enjoy full power backup and other smart home features such as peak-shaving and no-grid operation.

The storage-ready hybrid inverter is available in 3.8kW, 7.6kW, and 11.4kW. The 2-to-1 DC/AC ratio allows you to double your PV capacity, i.e. the 11,400W inverter will accommodate up to 22,800W of solar power.

The 3,800W inverter features 2 MPPT channels and a low 50V starting voltage, providing extreme flexibility when configuring the PV strings.

Tigo’s EI app will give you complete accessibility to the inverter and system data. No additional communication devices are needed; the inverter’s built-in Wi-Fi capability will connect wirelessly with your home router.
