PLEASE READ THIS FIRST
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION
• This manual contains important instructions for installation and
maintenance of the Tigo Energy® product models MM-ES-
050V300W, MM-ES075V350W, MM-ES110V300W, MM-ES-
170V300W, MM-2ES050V300W, MM-2ES075V350W, MMJ-
ES050V300W, HBF-ES050300W, ES-GTWY-020, MMU-ES,
and related Tigo Energy software applications.
• Risk of electric shock, do not remove cover, disassemble, or
repair, no user serviceable parts inside. Refer servicing to quali-
ed service personnel.
• Before installing or using the Tigo Energy® Maximizer™ Sys-
tem, please read all instructions and warning markings on the
Tigo Energy products, appropriate sections of your inverter
manual, photovoltaic (PV) module installation manual, and other
available safety guides.
• Failure to adhere to these instructions may result in injury or
death, damage to the system or voiding the factory warranty.
• To reduce risk of re and shock hazard, install this device with
strict adherence to National Electric Code (NEC) ANSI/NFPA
70 and/or local electrical codes. When the photovoltaic array is
exposed to light, it supplies a DC voltage to the Tigo Energy®
Module Maximizer™. The Module Maximizer starts in the “ON”
state and its output voltage may be as high as the PV module
open circuit voltage (Voc) when connected to the module. The
installer should use the same caution when handling electrical
cables from a PV module with or without the Tigo Energy Mod-
ule Maximizer attached.
• Installation must be performed by trained professionals only.
Tigo Energy does not assume liability for loss or damage result-
ing from improper handling, installation, or misuse of products.
• Remove all metallic jewelry prior to installing the Tigo Energy
Module Maximizer to reduce the risk of contacting live circuitry.
Do not attempt to install in inclement weather.
• Do not operate the Tigo Energy Module Maximizer if it has
been physically damaged. Check existing cables and connec-
tors, ensuring they are in good condition and appropriate in
rating. Do not operate the Tigo Energy Module Maximizer with
damaged or substandard wiring or connectors. Tigo Energy
Module Maximizer must be mounted on the high end of the PV
module back-sheet or racking system, and in any case above
ground.
• Do not connect or disconnect under load. Turning off the
Inverter and/or the Tigo Energy products may not reduce this
risk. Internal capacitors within the inverter can remain charged
for several minutes after disconnecting all power sources.
Verify capacitors have discharged by measuring voltage across
inverter terminals prior to disconnecting wiring if service is re-
quired.
• Service Personnel: Check the voltage of the array after activat-
ing the Tigo Energy® PV-Safe™ function on the MMU prior to
performing service.
• Always assume Module Maximizer is in “ON” state, or may turn
on when restarting.

!
!When using 2ES Dual Maximizers on an odd-length
string, connect the medium length input cables of
the last Maximizer in the string together.
The shortest pair of input leads should be
connected to the rst panel of each pair.

7. INITIATING DISCOVERY
Discovery
For systems with multiple Management Units (MMU) initiate discov-
ery one by one, ensuring that GTWY discovery is complete before
moving to the next MMU.
This may take several minutes to several hours depending on the
size of the system.
