Why Install the GO
Optimized ESS
Optimized Production
Get more energy from every solar module.
- Module-level optimization maximizes output even with shading or mismatch
- Reclaimed Energy shows the measurable production benefit from optimization
- Module-level monitoring helps verify system performance and simplify troubleshooting
Efficient Storage
Capture and store more solar energy with DC-coupled architecture.
- DC-coupled battery improves system efficiency compared to AC-coupled designs
- Store excess production instead of clipping it
- One inverter manages both solar generation and battery charging
Flexible Configurations
Design systems that adapt to real installations.
- Storage can be sized to match homeowner needs
- EV charging can be integrated into the same ecosystem
- Compatible with a wide range of modules and residential system layouts
Professional Platform
The GO
Optimized ESS
The Tigo GO Optimized Energy Storage System (ESS) brings together solar optimization, hybrid inversion, battery storage, EV charging, and energy intelligence into one integrated platform designed for residential installations.
The GO Optimized ESS enables installers to deliver systems that maximize production, simplify installation, and provide full visibility for long-term system performance.
One Optimized System
One platform.
Every component.
Built for the installer.

TS4 OPTIMIZERS
Maximum Production from Every Module
Tigo TS4 optimizers ensure that each solar module operates independently, preventing underperforming panels from reducing the output of the entire string.
Optimized production
Improve production when shading or mismatch is present with DC:DC optimizers
Module monitoring
View module-level performance, diagnostics and alerts to lower O&M costs and maximize uptime
Safety compliance
Meet safety codes and help protect first responders with rapid shutdown at the module-level
Universal fit
Works with virtually any module - up to 800W - on any application, from residential to commercial and even utility.
With TS4 optimizers, installers can design systems that perform reliably even on complex roofs.
EI Inverter
The Intelligent Energy Hub
The Tigo EI inverter manages solar production, battery storage, and household energy consumption within a single system architecture.
- Hybrid inverter supports both PV generation and battery storage
- Hybrid inverter supports both PV generation and battery storage
- Hybrid inverter supports both PV generation and battery storage
- Hybrid inverter supports both PV generation and battery storage
The EI inverter acts as the central control point of the GO Optimized ESS.

Installer Benefits
Why Tigo Works
For You
TS4, GO ESS, and EI are designed with installers in mind — less time on site, fewer service calls, and happier customers.
Built-In Rapid Shutdown
Full compliance with NEC 2017 690.12 without additional hardware. Active fire protection at module level.
5-Second Installation
TS4 connects directly to panel back — no special tools. Twelve panels per hour minimum per installer.
Panel-Level Monitoring
Identify faults, shading, or underperformance in 30 seconds without climbing the roof. AI flags anomalies automatically.
Advanced Installer Portal
Manage all projects from one screen — status, alerts, performance reports, and technical support with one click.
Open Compatibility
TS4 works with SolarEdge, SMA, Fronius, Huawei, and dozens of other inverters. No vendor lock-in.
DC Coupling Efficiency
Save up to 3% vs AC coupling — energy undergoes fewer conversions, less heat, more kWh for the customer.
Deliver the Next Generation
