does this need the internet to work??

A1 SolarStore

Optimization and rapid shutdown function locally. Internet is only needed for cloud monitoring, alerts, and remote visibility.

what does this optimizer do

A1 SolarStore

It boosts energy from each module by reducing mismatch (shade, soiling, etc.), adds module-level monitoring, and supports rapid shutdown when used with the required Tigo components.

Smarter energy at the module

TS4-A-O optimizes each module independently to mitigate shade, soiling, and mismatch—helping the whole array perform closer to its potential while providing per-module production visibility.

Open, inverter-agnostic design

Use the optimizers with most leading string inverters and system voltages up to 1000/1500 V for maximum design flexibility and easy retrofits.

Built for rooftops

An IP68 enclosure withstands heat, cold, dust, and driving rain. With wireless 2.4 GHz and/or PLC communications, commissioning is fast and ongoing monitoring is reliable.

Installer-friendly

Compact hardware snaps on quickly, with clearly labeled MC4/EVO2 connectors and straightforward commissioning through the Tigo Energy Intelligence app.
