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

The Envertech microinverter system is an on-grid microinverter system with

world-top-class technology. This manual gives details about the safe installation

and operation of the Envertech microinverter.

The three key elements of an Envertech microinverter system include:

EVT1600SE/EVT1800SE/EV2000SE microinverter: Converting the DC of the PV

module into AC

DANGER indicates a hazardous situation which, if not

avoided, will result in death or serious injury.

WARNING indicates a hazardous situation which, if not

avoided, can result in death or serious injury or

moderate injury.

NOTICE indicates a situation that can result in property

damage, if not avoided.

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

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.

Only qualified personnel may connect the Envertech

microinverter to the utility grid after receiving prior approval

from the electrical utility company.

You must install the microinverter system under connection

neither to the grid nor to the PV modules (or if not

disconnected, the modules should be shaded).

Installation could only be implemented when the system is

disconnected from the grid, and the solar panel has been

covered or disconnected.

Microinverters and modules must be connected to the ground. Fix the

screws to the microinverter installation hole. Make sure that the grounding

screw thread is firmly connected the bracket.

Step 4. Install the Wi-Fi antenna

Rotate the antenna clockwise until it is firmly secured to the microinverter.

Step 5. Connect the trunk cable with T-connector

Plan each cable segment to allow T-connectors on the trunk cable to align

with each PV module. Allow extra length for slack, cable turns, and any

obstructions.

Mark the approximate centers of each PV mod-ule on the PV racking.

Lay out the cabling along the installed racking for the AC branch circuit.

Note: Please make sure that there are less than 2 units of

EVT1800SE/EVT2000SE or less than 3 units of EVT1600SE in each branch

(12AWG). The maximum number per 10 AWG branch is 3 for EVT1800SE/

EVT2000SE or 4 for EVT1600SE.

Step 6. Connect to the trunk cable

Connect female AC connector to the quick plug T-connector of the trunk

cable.

Step 7. Fasten cables

Fasten AC cables and trunk cables to the rack with cable ties.

Step 8. Cover any unused connector with end caps

Insert the end cap into the connector on the unused end, and check if it is

inserted in place.

Step 9. Connect to the grid

1) Remove the skin of the two ends of the extension cable by y=40mm

and remove the skin of internal wires by x=14mm. Set the metal terminals

onto the open parts and clamp them to tighten the connection;

2) Connect the other side of the extension cable to the air switch.

a. Connect more than one microinverters in the system.
