Tigo Energy Maximizer Management Unit

The MMU is Tigo's remote monitoring solution. It comes standard with the maximizer unit and one gateway (GTWY). Each MMU can support up to 360 maximizers. Because the gateway can only support 120 maximizers, you will need to order an additional gateway if your array is larger than this.

Detailed Description

For residential, commercial and utility scale PV arrays, the Tigo Energy Maximizer System optimizes power output per each module (solar panel); 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. The Tigo Energy Maximizer Management Unit (MMU) communicates between the Module Maximizers and the Inverter, controls processes in real time and sends data to a remote server in order to allow multiple users to observe and interact with the monitoring system.

Each Tigo Energy Maximizer system (patented) includes one MMU per project, with the option of a second unit for system redundancy. The MMU has a manual user interface and LCD display housed in a NEMA3 enclosure for onsite programming. The MMU mounts near the inverter and communicates with each PV module in the system, provides management and control functions for the module Maximizers, and serves as a gateway to the Data Center. The Maximizer Management Unit is pre-configured with CAT-5 Ethernet access. The MMU can be used as a qualifying inverter and overall system performance monitoring interface for legacy installations.

The MMU includes the Tigo Energy PV-SAFE button - a unique onsite safety feature located on the front of the Maximizer Management Unit. With one push of the red button, an onsite operator or emergency personnel can deactivate the entire array for maintenance or emergency purposes (patented). PV-Safe enables each module to be electrically removed from the high voltage DC cabling limiting the voltage exposure to the open-circuit voltage (Voc) of a single module. As part of the Tigo Energy system, this function can be activated with the safety button or via a remote management console. The system can be installed, maintained or approached by fire personnel without the exposure to voltage levels typically in excess of 400 volts.

Features

• 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

Secure remote access to the MMU via the Tigo Energy MaxiManager software applications is available through any internet-enabled computer, with views available for system owners, installers, power plant operators and emergency services personnel. Simple, easy-to-understand graphics allow for quick analysis of the real-time output and historical performance of each system, and the ability to view and remedy system faults, error codes or alerts.
