The micro inverter offers unique technology that enables much
improved solar energy harvest, increased reliability, simplified
installation and efficient management of solar power systems.
Each micro inverter is individually connected to one PV module in
the solar panel array. This unique configuration achieves Maximum
Power Point Tracking (MPPT) at the PV module level, thus
eliminating single-point failure, minimizing the effect of shading,
soiling, orientations or PV module aging, and improving the
system’s energy harvest by up to 50%.

2.2 Optimal Reliability
Micro inverter systems are inherently more reliable than traditional inverters. The
distributed nature of a micro inverter system ensures that there is no single point of
system failure in the PV system.Micro inverters are designed to operate at full
power at ambient temperatures as hign as 65℃ (150℉). The micro inverter housing
is designed for outdoor installation and complies with the IP65 environmental
enclosure rating standard:
IP65 rating definition: Indoor or outdoor use primarily to provide a degree of
protection against hose-directed water, the entry of water during occasional
temporary submersion at a limited depth, and damage from extemal ice formation.
NOTE: To ensure optimal reliability and to meet warranty requirements. the micro
inverter must be installed according to the instruction in this manual.
2.3 Easy of Design
PV systems using micro inverters are very simple to design and install. You will not
need string calculations, and you can install individual PV modules in any
combination of PV module quantity, type, age and orientation. You won’t need to
install cumbersome traditional inverters. Each micro inverter quickly mounts on the
PV racking, directly beneath each PV module. Low voltage DC wires connect from
the PV module directly to the co-located micro inverter, eliminating the risk of
personnel exposure to dangerously high DC voltage.

2 Micro Inverter System
,
The micro inverter system is the world s most technologically advanced inverter
system for use in utility-interactive applications. This manual details the safe
installation and operation of the micro inverter.
2.1 How It work
The micro inverter maximizes energy production from your photovoltaic (PV) array.
Each micro inverter is individually connected to one PV mondule in your array. This
unique configuration 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 affected by shading, soiling, orientation, or PV module mismatch, the
micro inverter ensures top performance for its associated PV module. The result is
maximum energy production from your PV system.

8.2 Troubleshoot an Inoperable Micro Inverter
To troubleshoot an inoperable micro inverter, follow the steps in the order shown.
WARNING: Be aware that only qualified personnel should troubleshoot the PV array
or the Micro inverter.
Best Practice: Never disconnect the DC wire connectors under load. Ensure that no
current is flowing in the DC wires prior to disconnecting. If necessary, use an opaque
covering to cover the PV module prior to disconnecting the PV module. Always
disconnect AC power before disconnecting the PV module wires from the micro
inverter. The AC connector of the micro inverter is suitable as a disconnecting
means.
WARNING: The AC and DC connectors on the cabling are rated as a disconnect
only when used with a micro inverter.
WARNING: The micro inverters are powered by DC power from the PV modules.
Make sure you disconnect the DC connections and reconnect DC power to watch for
the LED blinks one minute after DC is applied.
Make sure AC breakers and disconnects are closed.
Check the connection to the utility grid and verify that the utility voltage is within
allowable ranges shown in the Technical Data section on page 7 of this manual.
Verify that AC line voltage at all solar power circuit breakers at the load center
and subpanels is within the ranges shown in the following table.
Verify that AC line voltage at the junction box for each AC branch circuit are within
the ranges are shown in the following table: econnect DC power to watch for the
LED blinks one minute after DC is applied.
Using an disconnect tool, disconnect the AC cable for the micro inverter in
question from the cable.
Verify that utility power is present at the micro inverter by measuring line to line
and line to neutral at the cable connector.
Visually check that the AC branch circuit connections (cable and AC connections)
