About the Microinverter
This system is composed of a family of microinverters that convert direct current (DC) into alternang current (AC) and
feeds it into the public grid. The system is designed for the incorporaon of one microinverter for one, two, or four
photovoltaic modules. Each microinverter works independently to deliver the maximum power generaon of each
photovoltaic module. This setup enables the user to control the producon of a single photovoltaic module directly,
consequently improving the flexibility and reliability of the system.
About the Manual
This manual contains important instrucons for the D350-M1 / D700-M2 / D1500-M4 microinverters. It must be read in
its enrety before installing or commissioning the equipment. For safety, only qualified technicians, who have received
training or have demonstrated skills can install and maintain this microinverter under the guide of this document.
Other Informaon
Product informaon is subject to change without noce. Please refer to Power Center+ official website at
www.duracellpowercenter.com for the latest version of the installaon manual.

7.5 On-site Inspecon (For qualified installers only)
To troubleshoot an inoperable microinverter, follow the steps in the order shown.
1. Verify the ulity voltage/frequency are within ranges as shown in the technical data.
2. Check the connecon to the ulity grid. Verify ulitypower is present at the inverter in queson by removing AC, then
DC power. Never disconnect the DC wires while the microinverter is producing power. Re-connect the DC module
connectors and watch for five short LED flashes.
3. Check the AC branch circuit interconnecon between all the microinverters. Verify each inverter is energized by the
ulity grid as described in the previous step.
4. Make sure that any AC breakers are funconing properly and are closed.
5. Check the DC connecons between the microinverter and the PV module.
6. Verify the PV module DC voltage is within the allowable range as shown in the technical data.
7. If the problem persists, please call Power Center+ customer support.
Warning! Do not try to repair the microinverter. If the troubleshoong fails, please return it to the factory for
replacement.

7.6 Removing a microinverter
1. De-energize the AC branch circuit breaker.
2. Remove the PV panel that is covering the microinverter from the racking, and cover the panel(s) that connect to the PV
input(s).
3. Use a DC rated clamp meter to measure and make sure there is no current flowing in the DC wires between the panel(s)
and the microinverter.
4. Use the AC disconnect tool to remove the AC connectors.
5. Use the DC disconnect tool to remove the DC connectors.
6. Un-screw the fixing screw(s) on the top of the microinverter and remove the microinverter from the PV racking.
7.7 Installing the replacement microinverter
1. Record the new microinverter’s serial number.
2. Ensure the AC branch circuit breaker is OFF, and follow the microinverter installaonsteps to install the replacement
unit.
3. In the monitoring plaorm (if customer already registered the PC-Pro online) select the [Device List]page and locate the
device that you just replaced. Click the down arrow next to the[More] on the right side of the page, and select [Replace].
Input the new microinverter’s serial number and click [Ok] to complete the staon changes.
Remove the microinverters as per secon 7.6 above.
8.1 Storage and Transportaon
Package and protect individual components using suitable means to make the transport and subsequent handling easier.
Transportaon of the equipment, especially by road, must be carried out by suitable ways for protecng the components (in
parcular, the electronic components) from shock, humidity, vibraon, etc. The microinverter storage temperature is -40 to
85 .
It is the customer’s responsibility to examine the condion of the components transported. Upon receipt of a shipment, it is
necessary to check the contents for any external damage as well as verify receipt of all items. Call the delivering carrier
immediately if damage or shortage is detected. If inspecon reveals damage to the inverter, contact the supplier, or an
authorized distributor for repair and/or return.

8.2 Disposal
If the equipment is not used immediately or is stored for long periods, check that it is correctly packed. The
equipment must be stored in well-venlated indoor areas that do not have characteriscs that might damage the
components of the equipment.
Take a complete inspecon when restarng aer a long me or prolonged stop.
Please dispose the equipment properly aer scrapping, which are potenallyharmful to the environment, in accordance with
the regulaons in force in the country of installaon.
Only authorized personnel are allowed to carry out the maintenance operaons and are responsible to report any
anomalies.
Always use the personal protecve equipment provided by the employer when carrying out the maintenance operaon.
During normal operaon, check that the environmental and logisc condions are correct. Make sure that the condions
have not changed over me and that the equipment is not exposed to adverse weather condions and has not been
covered with foreign bodies.
IMPORTANT! DO NOT use the equipment if any problems are found, and restore the normal condions aer the fault
has been removed.
Conduct an annual inspecon on various components, and clean the equipment with a vacuum cleaner or special
brushes.
WARNING! Do not aempt to dismantle the microinverter or make any internal repairs! In order to preserving the
integrity of safety and insulaon, the microinverters are not designed to allow internal repairs!
NOTE: The AC output wiring harness (AC drop cable on the microinverter) cannot be replaced. If the cord is damaged
the equipment should be scrapped.
WARNING! Maintenance operaons must be carried out with the equipment disconnected from the grid (power
switch open) and the photovoltaic modules covered or isolated, unless otherwise indicated.
NOTE: For cleaning, do not use rags made of filamentary material or corrosive products that may corrode parts of
the equipment or generate electrostac charges.
