The Tigo difference

Maximize Your PV Potential with a Unified Tigo Ecosystem

Tigo’s TS4 Flex MLPE and GO Optimized ESS work together to eliminate mismatch, reduce conversion steps, and provide total visibility from the roof to the battery.

Flexible

Choose your
features


Tigo lets you select the specific features needed for each project, fully integrated into the GO ESS ecosystem:

Optimization: Recover 30–40% of energy lost to shade.

Monitoring: Pinpoint-accurate module-level data.

Rapid Shutdown: NEC 690.12 certified compliance.

Universal

High-Efficiency
DC-Coupling


A unified DC-coupled architecture that works with the largest network of inverters while increasing storage output:

Direct DC Storage: Save 5.1% more energy per cycle.

Plug-and-Play: Color-coded wiring for rapid installation.

No Multi-Step Conversion: Stays in DC to minimize losses.

Reliable

Proven Performance Over 10+ years


Tens of millions of units shipped worldwide with the industry's lowest failure rates and advanced management:

Yield Boost: Average 8% increase in total production.

Remote Diagnostics: Reduce O&M costs and site visits.

Safe Chemistry: Cobalt-free LFP batteries for residential safety.



Standalone Flexibility

Standalone Performance. Universal Integration.

The Tigo TS4-A Flex MLPE is hardware-agnostic by design. Enhance any commercial solar installation with module-level intelligence and panel-level monitoring, while seamlessly integrating with our residential GO ESS for a complete solution.

Universal Compatibility

Avoid Inverter Lock-in: Designed to work with most third-party inverters, ensuring you aren't stuck in a closed ecosystem. 

Seamless Integration: Adds rapid shutdown compliance and panel-level monitoring to new or existing string systems without changing your current setup.

Standalone Optimization

Increased Production: Reclaims energy lost to shade and mismatch, typically increasing system output by 6–7%.

Flexible Deployment: Can be added exactly where needed most—such as shaded sections or repowering older systems—to keep entry costs low.

GO ESS Ready

Efficiency Gains: Supports a pure DC-coupled energy chain that can unlock an additional 5.1% efficiency gain when paired with energy storage.

Scalable Path: Provides a simple way for installers to scale their energy storage offerings for commercial or residential projects.

Easy monitoring

Powered by Tigo Energy Intelligence (EI)

Tigo Energy Intelligence is the software that unifies the entire Tigo GO ESS Residential solution under one platform. With the most granular monitoring in the industry and historical data access, you can pinpoint and diagnose issues remotely.

Maximize site uptime:

Get real-time alerts when a performance or safety issue arises so the site can quickly be returned to normal. More uptime = more energy.

Enhance the customer experience:

Get visibility to all sites from one spot with fleet, system, and module level performance data. Get more referrals with happier customers.

Minimize O&M costs:

Detect system level, string level, and module level issues to streamline troubleshooting and maintenance. Save money with fewer truck rolls.

how it works

See How TS4-A Flex MLPE and GO Optimized ESS Works

Tigo optimizers

Maximize production of PV modules up to 725W.

Inverter

Connects to the TS4's, GO Battery, ATS, and wirelessly sends data to the Tigo Energy Intelligence platform.

GO Battery

Only 3 connections required per battery. Up to 6 battery modules can be used with each Tigo Inverter.

ATS

Automatic Transfer Switch to control backup loads. With optional generator connection.

MLPE: Tigo TS4-A-O, -M, or -S

Tigo TS4 units are connected to each module. Customers can use any combination to maximize returns for their particular site.

Required: CCA + TAP

Tigo's Cloud Connect Advanced is the data hub for Tigo's TS4 and other metered devices including the inverter, battery, etc. The CCA connects with an RS485 cable to the TAP which wirelessly communicates with the TS4s.

Tigo Energy Intelligence

All of the module-level data, and any third party data connected to Tigo's CCA can be viewed in the Tigo Energy Intelligence monitoring portal.



Global trust

Trusted by industry leaders in solar

Tigo systems are rigorously tested with the leading inverter and module brands. It's just part of the reason why Tigo TS4s are the most reliable and flexible in the industry.
