2.APsystems Microinverter System Introduction
This integrated system improves safety; maximizes solar energy harvest; increases system
reliability, and simplifies solar system design, installation, maintenance, and management.
APsystems Microinverters maximize PV energy production
Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which
ensures that the maximum power is produced 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 Microinverter ensures top performance from the array by
maximizing the performance of each module within the array.
More reliable than centralized or string inverters
The distributed APsystems Microinverter system ensures that no single point of system failure
exists across the PV system. APsystems Microinverters 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 environmental enclosure rating.
Simple to install
You can install individual PV modules in any combination of module quantity,orientation, type,
and power rate.
Smart system performance monitoring and analysis
The APsystems 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 and configurating the ECU, the full network of APsystems Microinverters
automatically reports to the APsystems 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. (See ECU manual for instructions.)

6.Troubleshooting
Qualified personnel can use the following troubleshooting steps if the PV system does not
operate correctly:
6.1 Status Indications and Error Reporting
6.1.1 Start up LED
When the 1st PV module is connected to the microinverter, the LED flashes once red, then 3
times green quickly. This indicates correct operation.
6.1.2 Operation LED
Flashing Slow Green (10 sec. gap) - Producing power and communicating with ECU
Flashing Fast Green (2 sec. gap) - Producing power and not communicating with ECU
over 60mins
Flashing Red - Not producing power
Steady Red - Electrode assembly
6.1.3 GFDI Error
A solid red LED indicates the Microinverter has detected a Ground Fault in the PV
system(GFDI alarm).Until the GFDI alarm has been cleared, the LED will remain red and
the ECU will keep reporting the fault.After the ground fault is fixed, follow the instructions
in the ECU Installation and Operation Manual to clear this GFDI error reporting.
6.1.4 Other Faults
All other faults are reported to the ECU. Refer to the ECU Installation and Operation
Manual for a list of additional faults and troubleshooting procedures.

6.Troubleshooting
6.2 Troubleshooting a non-operating APsystems Microinverter
There are two possible overall areas of trouble:
A. The Microinverter itself may be having problems.
B. The Microinverter itself is working fine but it is having trouble communicating with the
ECU. The items below refer to Microinverter issues, not communication issues (addressed in
the ECU manual).
A quick way to tell whether the issue is the Microinverter or communication problem with the
ECU:
1. Diagnosing from the Microinverter: A red light – either blinking or solid on the
Microinverter, or no light at all. No light, or a red light, means it is definitely a Microinverter
problem.
2. Diagnosing from the ECU:
a. No-Data-Display: This is probably a communication issue- not a Microinverter
problem.
b. Problems with erratic display: Data is displayed for some period and then no data is
displayed: most likely a communication issue.
c. 0 watts, or 2 watts: Possibly a Microinverter problem
d. Erratic data display that is not coordinating with data displays from other units: most
likely a Microinverter problem.
To troubleshoot a non-operating APsystems Microinverter, Follow
the steps below in order to:
1. Verify the utility voltage and frequency are within ranges shown in the Technical Data
section of this manual.
2. Check the connection to the utility grid. Verify utility power is present at the inverter in
question by removing AC, then DC power. Never disconnect the DC wires while
the microinverter is producing power. Reconnect the 1st module and check that
the LED flashes green 3 times.
3. Check the AC branch circuit interconnection between all the microinverters. Verify each
inverter is energized by the utility grid as described in the previous step.
4. Make sure that any AC breaker are functioning properly and are closed.
5. Check the DC connections between the microinverter and the PV module.
6. Verify the PV module DC voltage is within the allowable range shown in the Technical
Data of this manual.
7. If the problem persists, please call APsystems Customer Support.
Do not attempt to repair the APsystems Microinverter. In the event of failure of the
troubleshooting methods and after validation of the fault by the APsystems
technical service, please return the defective microinverter to your distributor for
replacement.
