2.1 How it Works
The Envertech microinverter maximizes energy production from your photo-voltaic(PV) array. Each
Envertech microinverter is individually connected to one PV module in your array. This unique
conguration 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 aected 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.
You can view the real-time data from a web browser or Envertech app.
This integrated solar system maximizes energy harvest, increases system reliability, and simplied
design, installation and management.
3.1 Overview
3.2 Major Characteristics
Envertech microinverters have the following characteristics which make Envertech microinverters
“Highly Ecient, Highly Reliable, Highly Cost Eective”:
Low DC input voltage.
Wide MPPT voltage range ensures high yield under various weather conditions.
High MPPT accuracy ensures minimum power loss during converting.
Complete set of protective functions.
Also, the following protective functions are integrated into Envertech microinverters:
Overvoltage/undervoltage protection
Overfrequency/underfrequency protection
Faulty grounding protection
Grid monitoring
Current monitoring in grounding
DC current monitoring
EVT1200 can be adapted to almost all 60-cell or 72-cell modules. Before installation, please check
the parameters of the microinverters and modules to ensure that they are compatible.
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.
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 protec-
tion level.
NOTE：To ensure optimal reliability and to meet warranty requirements, the EVT1200 microinverter
must be installed according to the instructions in this manual.
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.

required by local grid standards.
5. Conrm 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 on-grid circuit breakers are o.
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.
8.3 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 o the microin-
verter 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.
1. Turn o AC branch circuit breaker.
2. Disconnect the microinverters in the following procedure:
Pull the AC connectors of both sides of the microinverters in the opposite direction with appropri-
ate force.
Single-Phase 230 VAC
L to N 180 to 265 VAC L1 to L2 to L3 310 to 460 VAC
Three-Phase 230 VAC

3. Cover the PV module with an opaque, and then disconnect the PV module DC connectors from
the microinverter.
4. Loosen the grounding screw and remove the grounding wire.
5. Take o the microinverter from the PV frame.
9. System Diagram
Do not leave the AC connectors open for a long time. All unused
connectors must be covered by sealing caps.
