Data Sheet Tigo MM-2ES

Detailed Description

For residential, commercial and utility scale photovoltaic solar arrays, the Tigo Energy Maximizer system optimizes the power output of each module; delivers module-level data for operational management and performance monitoring; and provides the ability to deactivate the high voltage DC bus for safer installation, maintenance or fire fighting.

Tigo Energy Dual Maximizers are key components of the system which reside at each module (one per up to two solar modules). The Dual Maximizer provides data acquisition, communication to the Tigo Energy Maximizer Management Unit, and power point control. The very small electronics footprint of the Maximizer has been designed to minimize cost and maximize reliability. Tigo Energy Maximizer MM-2ES is ideal for new construction or retrofit applications around the world.


  • Accelerate system payback
  • Maximize the power output of the array under any condition
  • Reconsider previously rejected projects because of unfavorable shade or orientation
  • Maintain best-in-class conversion efficiency
  • Manage the system with module-level data to minimize operational costs and keep the system at peak performance throughout its lifetime
  • Introduce an unprecedented level of safety for new and existing PV solar installations
  • Simplify the balance-of-system design, especially for high Voc or thin-film modules

Tigo Energy's patented "Impedance Matching" approach manages the energy harvest and sends information to the Maximizer Management Unit for reporting and control. The Tigo Energy Dual Maximizer (MM-2ES) connects in a series topology. MM-2ES maintains bestin-class system conversion efficiencies.

The Tigo Energy Dual Maximizer includes the PV-Safe technology which greatly enhances the safety of a PV solar installation. As part of the Tigo Energy Maximizer system, this function can be activated with a safety button or via a remote management console. The system can also be activated by fire personnel to avoid exposure to voltage levels typically in excess of 400 volts.

The Tigo Energy Dual Maximizer is packaged in a NEMA3R enclosure (water and weather resistant), and conforms to UL and IEEE safety standards. There are Module Maximizer options to fit any PV module, crystalline silicon or thin-film, regardless of output voltage or power rating.

The Tigo Energy Dual Maximizer is designed to integrate seamlessly with the industry-leading Tigo Energy Maximizer System. Each unit can be used with either one or two PV modules, giving system designers added flexibility. In addition, the Dual Maximizer can be mixed with single Module Maximizers in the same system – they can be connected on the same string, and can use the same MMU and Gateway communications system simultaneously.
