1. Important safety information
This manual contains important instructions to follow during installation and maintenance of
the APS Photovoltaic Grid-connected Micro-inverter. To reduce the risk of electrical shock
and ensure the safe installation and operation of the APS Micro-inverter, the following
symbols appear throughout this document to indicate dangerous conditions and important
safety instructions.
WARNING: This indicates a situation where failure to follow instructions
may cause a serious hardware failure or personnel danger if not applied
appropriately. Use extreme caution when performing this task.
NOTE: This indicates information that is important for optimized
Micro-inverter operation. Follow these instructions closely.
Symbols replace words on the equipment, on a display, or in manuals.
Trademark
Caution, risk of electric shock
Caution, hot surface
Symbol for the marking of electrical and electronics devices according
to Directive 2002/96/EC. Indicates that the device, accessories and the
packaging must not be disposed as unsorted municipal waste and must
be collected separately at the end of the usage. Please follow Local
Ordinances or Regulations for disposal or contact an authorized
representative of the manufacturer for information concerning the
decommissioning of equipment.
CE mark is attached to the solar inverter to verify that the unit follows
the provisions of the European Low Voltage and EMC Directives

Qualified
personnel
Person adequately advised or supervised by an electrically skilled person
to enable him or her to perceive risks and to avoid hazards which
electricity can create. For the purpose of the safety information of this
manual, a "qualified person" is someone who is familiar with
requirements for safety, refrigeration system and EMC and is authorized
to energize, ground, and tag equipment, systems, and circuits in
accordance with established safety procedures. The inverter and endues
system may only be commissioned and operated by qualified personnel.
Safety Instructions
• Only qualified professionals should install and/or replace APS Micro-inverters.
• Perform all electrical installations in accordance with local electrical codes.
• Before installing or using the APS Micro-inverter, please read all instructions and
cautionary markings in the technical documents and on the APS Micro-inverter
system and the PV-array.
• Be aware that the body of the APS Micro-inverter is the heat sink and can reach a
temperature of 80°C. To reduce risk of burns, do not touch the body of the
Micro-inverter.
• Do NOT disconnect the PV module from the APS Micro-inverter without first
disconnecting the AC power.
• Do NOT attempt to repair the APS Micro-inverter. If it fails, contact APS Customer
Support to obtain an RMA number and start the replacement process. Damaging or
opening the APS Micro-inverter will void the warranty.
• Caution!
The external protective earthing conductor is connected to the inverter protective
earthing terminal through AC connector.
When connecting, connect the AC connector first to ensure the inverter earthing
then do the DC connections.
When disconnecting, disconnect the AC by opening the branch circuit breaker first
but maintain the protective earthing conductor in the branch circuit breaker connect
to the inverter ，then disconnect the DC inputs.
In any circumstance, do not connect DC input when AC connector is unplugged.
2. APS Micro-inverter System Introduction
The APS Micro-inverter is an inverter system for use in utility-interactive applications,
comprised of three key elements:

• Altenergy Power Systems Micro-inverter
• Altenergy Power Systems Energy Communication Unit (ECU)
• Altenergy Power Systems Energy Monitor and Analysis (EMA) web-based monitoring
and analysis system
This integrated system improves safety; maximizes solar energy harvest; increases system
reliability; simplifies photovoltaic (PV) system design, installation, maintenance, and
management.
The APS Micro-inverters maximize energy roduction from hotovoltaic (PV)
arrays. Each PV module has individual Maximum Peak Power Tracking (MPPT) controls,
which ensures that the maximum power is exported to the utility grid regardless of the
performance of the other PV modules in the array. When PV modules in the array are
affected by shading, soiling, orientation, or mismatch, the APS Micro-inverter ensures top
performance from the array by maximizing the performance of each module within the
array.
The APS Micro-inverter system is more reliable than centralized or string
inverters. The distributed Micro-inverter system ensures that no single point of system
failure exists across the PV system. APS Micro-inverters are designed to operate at full
power at ambient temperatures of up to 65°C. The inverter housing is designed for outdoor
installation and complies with the IP65 environmental enclosure rating.

PV systems using APS Micro-inverters are very sim le to install. You can install
individual PV modules in any combination of module quantity, orientation, type, and power
rate.
The APS Micro-inverter system rovides smart system erformance monitoring
and analysis.
The APS Energy Communication Unit (ECU) is installed by simply plugging it into any wall
outlet and providing an Ethernet or Wi-Fi connection to a broadband router or modem. After
installing the ECU, the full network of APS Micro-inverters automatically reports to the APS
Energy Monitor and Analysis (EMA) web server. The EMA software displays performance
trends, informs you of abnormal events, and controls system shutdown when it is needed.

4. APS Micro-inverter System Installation
A PV system using APS Micro-inverters is simple to install. Each Micro-inverter easily
mounts on the PV racking, directly beneath each PV module. Low voltage DC wires connect
from the PV module directly to the Micro-inverter, eliminating the risk of high DC voltage.
Installation shall comply with local regulations and technical rules.
WARNING: Perform all electrical installations in accordance with local
electrical codes.
WARNING: Be aware that only qualified professionals should install and/or
replace APS Micro-inverters.
WARNING: Before installing or using an APS Micro-inverter, please read all
instructions and warnings in the technical documents and on the APS
Micro-inverter system itself as well as on the PV array.
WARNING: Be aware that installation of this equipment includes the risk of
electric shock.
WARNING: Do not touch any live parts in the system, including the PV array,
when the system has been connected to the electrical grid.
