APsystems Optimizer System Introduction
The APsystems optimizer is a DC-DC converter installed between PV
modules and a central string inverter to maximize the energy harvested
from each module. It can achieve module-level Maximum Power Point
Tracking (MPPT) and plays a critical part in the whole power system.
The APsystems PV Power Optimizer system is comprised of four key
elements:
APsystems Optimizer (OPT700/OPT700L)
Inverter
APsystems Energy Communication Unit (ECU)
APsystems Energy Monitor and Analysis (EMA) web-based
monitoring and analysis system

APsystems Optimizer System Introduction
This integrated system improves safety, maximizes solar energy harvest,
and increases system reliability.
The APsystems Optimizer increases PV energy
production by 5%-25%
Each APsystems PV Power Optimizer is individually connected to one or two solar
modules. Each PV module has individual Maximum Power Point Tracking
(MPPT) controls, which ensures that the optimum 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 shade, dust,
orientation, or any situation in which one module underperforms
compared with the other units, the APsystems optimizer ensures top
performance from the array by maximizing the performance of each module.
The APsystems Optimizer system is reliable, safe
and simple to install
APsystems PV Power Optimizers are installed to work with a string / central
inverter. They are designed to operate at full power at ambient outdoor
temperatures of up to 149°F (65°C). The inverter case is designed for
outdoor installation and complies with the IP67/NEMA 6P environmental
enclosure rating.
Smart system performance monitoring and analysis
The performance trends and data of APsystems PV Power Optimizers can be
monitored and analyzed with the APsystems Energy Communication Unit
(ECU) and APsystems Energy Monitor and analysis (EMA). The EMA software
informs you of abnormal events, and controls system shutdown when it
is needed.

APsystems Optimizer System Installation
A PV system using APsystems optimizers is simple to install. Each
optimizer easily mounts on the PV racking directly beneath
the PV module(s) or the module frame. Low-voltage DC wires
connect from the PV module directly to the optimizer, eliminating
the risk of a high-voltage DC charge.
Installation MUST comply with local regulations and technical rules.
WARNING: Perform all electrical installations in accordance
with local codes.
WARNING:Be aware that only qualified professionals should
install and/or replace the APsystems optimizer..
WARNING: Before installing or using an APsystems optimizer,
please read all instructions and warnings in the technical
documents and on the 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.
WARNING: Ensure the solar module and inverter has been
disconnected before installing an APsystems optimizer.
Additional installation components from APsystems
DC extension cable (sold separately)
Required parts and tools to complete the installation
In addition to your PV array and its associated hardware, you will need
the following items:
Mounting hardware suitable for module racking
A torque wrench and a Phillips screwdriver
A multimeter
WARNING: Be sure to verify the voltage and current specifications
of your PV module match with those of the optimizer.
WARNING: You must match the DC operating voltage range of
the PV module with the allowable input voltage range of the
APsystems optimizer.
WARNING: The maximum open circuit voltage of the PV module
must not exceed the specified maximum input voltage of the APsystems
optimizer.

Installation Procedures
Step 3 - Connecting the APsystems Optimizer DC output Cables
Figure 5
NOTE: Make sure that all DC cables are connected correctly.
NOTE: DC extension cable length can be customized based on
the actual installation environment. Please contact APsystems
to purchase the cables.
Step 4 - Completing the APsystems Installation Map
Fill in the APsystems registration cards, which provide system information
and the installation map. Feel free to provide your own layout if a larger or
more intricate installation map is required. The layout map provided is
designed to accomodate labels in vertical or horizontal orientation to meet
all the field PV connections.
a. Each APsystems optimizer has removable serial number labels.
Peel the labels off, affix one to the respective location on the
APsystems installation map, then affix another label to the PV
module frame so that it can be easily seen. The warranty cards
can be found in the appendix of this manual or at the APsystems
website, www.APsystems.com
b. Fill in the warranty cards and email to APsystems at
[e-mail]
c. APsystems will create the EMA account and email you the account
information. Then you can use the EMA website to view detailed
performance of your PV system. You can learn more information on
energy monitoring and analysis system from APsystems website

Installation Procedures
Figure 6
NOTE: 1. Step 1~4 can change sequence for convenience of installation.
2. Warranty card is located in Appendix last page of this manual.
Step 5 - Verifying Proper Optimizer Connection
When connected to the PV modules and exposed to light, the APsystems
optimizer will output a PV open circuit voltage. Therefore, the total string
voltage should be equal to the PV open circuit voltage times the number of
power optimizers connected in series in the string. The correctness of the
APsystems optimizer connection can be verified by measuring the polarity
and magnitude of the total string output voltage.
For example, each APsystems optimizer connect to two PV modules and
produce a PV open circuit voltage of 80V. If ten APsystems optimizers are
connected in a string, and then 800V should be produced.
If the measured open circuit voltage is abnormal, please see Troubleshooting
(p.10).
WARNING: DO NOT connect to other optimizer strings or the
inverter before verifying the optimizer connection. Output value
or wrong polarity will damage the optimizers or inverters.
Step 6 - Connecting the APsystems Optimizer to inverter
When verification is correct, connect the optimizer to the inverter. Pay
attention to polarity.

Troubleshooting
Qualified personnel can use the following troubleshooting steps if the
PV system does not operate correctly.
WARNING: Only qualified personnel should directly handle the
APsystems optimizer.
WARNING: Do not attempt to repair the APsystems Optimizer. If
troubleshooting methods fail, please return the optimizer to your
distributor for replacement.
When Verifying Proper Power Optimizer Connection:
1. When measuring the PV open circuit voltage, one or more
of the optimizers voltage value inconsistent with others.
Reason
Solution
One or more of the PV modules are not
connected properly to their optimizer.
Connect all the PV modules to their
optimizers securely.
There is something wrong with PV Power
Optimizer.
Please return the optimizer to your
distributor for replacement or contact
APsystems Customer Support to
service.
2. The PV open circuit voltage is zero.
Reason
Solution
One or more of the optimizers are
unconnected or skipped during the string
connection process.
Connect all the power optimizers.
3. The PV open circuit voltage is not zero but is lower than the
quantity of optimizer power.
Reason
Solution
One or more of the PV modules are not
connected properly to their
optimizer.
Connect all the PV modules to their
optimizers securely.
One or more of the optimizer are not
connected properly to their polarity.
Make sure all the optimizer are connected
properly to their polarities.
Maintenance
No need to Maintenance.
Adjustment
No need to Adjustment
