1. Important Safety Information
1.1 Read it First
This manual contains important instructions for the installation and maintenance
of the microinverter.
To reduce the risk of electrical shock, and to ensure safe installation and
operation of the microinverter, the following safety symbols appear throughout
this document to indicate dangerous conditions and important safety
instructions.
1.2 Safety Instructions
Do not use Envertech equipment in a manner not specified by the
manufacturer. Doing so may cause death or injury to persons, or damage to
equipment.
Be aware that only qualified personnel should install or replace the Envertech
microinverters and the cables and accessories.
Do not attempt to repair the Envertech microinverter; it contains no user-
serviceable parts. If it fails, contact Envertech customer service to start the
replacement process. Tampering with or opening the Envertech microinverter
will void the warranty.
If the AC cable on the microinverter is damaged or broken, do not install the
unit.
Before installing or using the Envertech microinverter, read all instructions and
cautionary markings in the technical description and on the Envertech
microinverter system and the PV equipment.
Connect the Envertech microinverter to the utility grid only after you have
completed all installation procedures and received approval from the electric
utility company.
Please be kindly note that the Envertech microinverter itself is a heat sink.
Under normal operating conditions, its temperature is 20°C above ambient, but
under extreme conditions, the microinverter can reach a temperature of 90°C.
Do not disconnect the PV module from the Envertech microinverter without
rusty disconnecting AC power.
2. Envertech Microinverter System

EnverBridge (Optional): monitoring and protecting PV system.
EnverPortal: http://www.envertecportal.com
EnverView: IOS, Android App
You can view the real-time data from a web browser or Enverview app.
This integrated solar system maximizes energy harvest, increases system
reliability. Simplifies design, installation and management.
2.1 How it Works
The Envertech microinverter maximizes energy production from your
photovoltaic (PV) array. Each Envertech microinverter is individually connected
to one PV module in your array. This unique conjuration means that an individual
Maximum Peak Power Point Tracker (MPPT) controls each PV module. This
ensures that the maximum power available from each PV module is exported to
the utility grid regardless of the performance of the other PV modules in the
array. That is, although individual PV modules in the array may be acted by
shading, soiling, orientation, or PV module mismatch, the Envertech
microinverter ensures top performance for its associated PV module. The result
is maximum energy production from your PV system.
2.2 Monitoring Device: EnverBridge
Once you install EnverBridge and have it connected to your broadband router or
modem, Envertech microinverters automatically begin to report to EnverBridge’s

3
server. EnverBridge monitoring system presents both real-time and history
performance data.
2.3 Optimal Reliability
Microinverter systems are inherently more reliable than traditional inverters.
The distributed nature of a microinverter system ensures that there is no single
point failure in the PV system. Envertech Microinverters are designed to operate
at full power at ambient temperatures as high as +65 ℃(150 ℉). The
microinverter casing is designed for outdoor installation and complies with the
IP67 protection level.
Note: To ensure optimal reliability and to meet warranty requirements, the
microinverter must be installed according to the instructions in this manual.
2.4 Simple Design
PV systems using Envertech microinverters are very simple to design and install.
You can install a combination of PV modules of any type, at any orientation and
in any quantity. You won’t need to install cumbersome traditional inverters. Each
microinverter can be quickly mounted on the PV rack, directly beneath each PV
module. Low voltage DC wires connect from the PV module directly to the co-
located microinverter, eliminating the risk of personnel exposure to dangerously
high DC voltage.
3. Product Information
Note: For optimum reliability and to comply with warranty conditions, the
microinverter must be installed according to the instructions in this manual.

6. Debugging and Operating
Please notice the symbols.
6.1 Energize the System
1. Turn on the switch or the circuit breaker at each microinverter AC branch.
2. Turn on the main AC circuit breaker in the distribution box. Your system will
start to produce power after 3 minutes.
3. Envertech microinverters begin to communicate through the power lines to
EnverBridge. The entire system will be detected within 10 minutes.
4. The voltage and frequency of the microinverter can be adjusted on the site. If
adjustments are required by your local utility company, installers can use
EnverBridge to manage grid parameters after all microinverters have been
detected.
6.2 Microinverter Operation
The Envertech microinverter is powered on when there is sufficient DC voltage
from the PV module. The LED light of each microinverter will blink green to
indicate normal start-up operation approximately 1 minute after DC power is
applied.
7. Troubleshooting and Maintenance
Adhere to all the safety measures described throughout this manual. If the PV
system does not operate correctly, the following troubleshooting measures can
be applied by qualified personnel.
7.1 LED Status Indications and Error Report
LED Startup:
The LED of each microinverter blinks red for a while at the beginning, and then
blinks green to indicate normal start-up approximately 10 seconds after DC
power is applied. If the LED blinks red after DC power is on, it indicates a failure
during the start-up.
Post-Startup LED Indications:
Check LED status to confirm the present situation.
Flashing Green: It indicates normal operation.
Flashing Red:
1. If red light flashes every 2 or 3 seconds, it indicates that the microinverter is
waiting for sun or prepare to produce energy.
2. If red light flashes continuously, it indicates that the microinverter is not
operating normally. The microinverter does not detect that the utility grid is
Only qualified personnel may connect the Envertech
microinverter to the utility grid after receiving prior approval
from the electrical utility company.
Ensure that all AC and DC wiring is correct. Ensure that none of
the AC and DC wires is twisted or damaged.
Do not attempt to repair the Envertech microinverter. It
contains no user-serviceable parts. If the microinverter fails,
contact your direct supplier or Envertech customer service to
obtain an RMA (return merchandise authorization) number and
start the replacement process.

within operable voltage/frequency range. The microinverter cannot produce
power until this is solved.
7.2 Troubleshoot an Inoperable Microinverter
To troubleshoot an inoperable microinverter, follow the steps in the order shown
below.
WARNING: Be aware that only qualified personnel should troubleshoot the PV
array or the Envertech microinverter.
Best Practice: Please do not disconnect DC connection while the system is
working. Ensure that no current is flowing in the DC wires prior to disconnecting.
If necessary, use an opaque to cover the PV module prior to disconnecting the
PV module. Always disconnect AC power before disconnecting the PV module
from the Envertech microinverter. Disconnecting AC connectors of the
microinverters is also a means of cutting off AC power.
WARNING: The AC andDC connectors on the cabling are rated as a disconnecting
point only when used with an Envertech microinverter.
WARNING: Envertech microinverters are powered by DC power from the PV
modules. Please disconnect and reconnect DC power to check the LED blinks 1
minute after DC is applied.
1. Make sure AC breakers are on.
2. Check the connection to the utility grid and verify that the grid voltage is within
allowable ranges shown in the Technical Data section.
3. Verify that AC voltage at all solar power circuit breakers of the load centers
are within the ranges shown in the following table.
4. Verify that AC line voltage at the junction box for each AC branch circuit is
within the ranges required by local grid standards.
5. Confirm if the microinverter side is connected to the grid by measuring the
voltage from AC line to line and line to neutral.
6. Visually check if AC branch circuit connection is correctly done. Reinstall if
necessary.-Check also for damage, such as rodent damage.
7. Make sure that all circuit breakers are off.
8. Disconnect and re-connect the PV modules’ DC connectors with
microinverters. The LED status of each microinverter will blink green to indicate
normal start-up operation soon after DC power is applied (less than one minute).
9. Attach an ammeter clamp to one conducting wire of the DC cables from the
PV module to measure the microinverter’s current. This will be under 1 Amp if
AC is disconnected.
10. Check the DC connection between the microinverter and the PV module. The
connection may need to be tightened or reseated. If the connection is worn out
or damaged, it needs replacement.
11. Verify with your utility company that grid frequency is within the regulated
range.
7.3 Disconnect Microinverters from PV Modules
If your problems are still unsolved with the steps above, please contact
Envertech tech support through www.envertec.com. If Envertech approves the
replacement, please take off the microinverter according to the following
instructions. In order to ensure the disconnection between the microinverter
and the PV Module will not be done while the microinverter is at working status,
please strictly follow the steps below.
