Tigo Energy
Tigo Energy built its reputation on module-level power electronics — the TS4 platform that adds optimization, monitoring and NEC-compliant rapid shutdown to almost any solar module. The line has since grown into a full residential ecosystem with the EI hybrid inverter family, EI battery enclosures and transfer switches.

View full detailsHow to Choose
Start with what the job actually requires. If you only need code compliance, the TS4-A-F fires and shuts down at the module and nothing more. If shading, mismatched roof planes or per-module reporting matter, step up to the TS4-A-O for optimization plus monitoring. Whole-system buyers should look at the EI line: the 7.6kW and 11.4kW hybrid inverters pair with the 9.9kWh EI battery and a 200A automatic transfer switch, so one manufacturer covers inverter, storage and backup switching with a single support path.

Our Tigo range spans 25 SKUs from single TS4 covers under $40 up to the EI battery with enclosure at roughly $2,333, including 20-packs of TS4-A-O optimizers for full-array deployments and both versions of the 200A automatic transfer switch.
Frequently Asked Questions
Do I need Tigo optimizers on every module?
Only where they earn their keep. NEC rapid shutdown must cover the array, but optimization only pays back on modules that see shading or sit on a different roof plane.
Will TS4 work with my existing inverter?
The TS4-A series is designed as an add-on for third-party string inverters. Confirm your inverter's string voltage window and add a Tigo Cloud Connect or TAP for monitoring.
Is the EI battery AC or DC coupled?
The EI system is designed around Tigo's own EI hybrid inverters for a DC-coupled install. Check the current compatibility list before pairing with another brand.
