Tigo Energy

Tigo Energy invented module-level power electronics for the retrofit world — and this collection stocks the genuine Tigo lineup: optimizers, rapid shutdown, and monitoring hardware that bolts onto almost any solar array, new or existing.

The TS4-A-O is the flexible MLPE platform: 700W-rated, 1500V, MC4-equipped optimizer units that add panel-level optimization and monitoring to standard string-inverter systems — recovering production from shaded, soiled, or mismatched modules without replacing the inverter. Rapid shutdown is Tigo's other stronghold: single-core and dual-core Pure Signal RSS transmitters in DIN-rail outdoor enclosures, meeting NEC 690.12 module-level shutdown requirements with a signal that rides the existing DC wiring — no extra control cable to pull. Monitoring runs through the TAP access point and Cloud Connect Advanced (CCA), with the RSS signal detector for commissioning verification.

For new builds, Tigo's EI line — including the 3.8kW EI hybrid inverter — brings the same module-level intelligence into a complete residential storage-ready system. Every Tigo product here is genuine factory stock with full warranty and design-tool support: Tigo's online designer validates TS4 compatibility against your specific inverter and modules. Send us your inverter model and module spec, and we will confirm the TS4 configuration, transmitter count, and monitoring kit before you order.
