Read This First
Dear customer, thank you for choosing Projoy products. We hope you will find our products
meet your needs for renewable energy. Meantime, we appreciate your feedback regarding our
products.
A DTU is a communication device for the Projoy microinverter system. DTU and
microinverters are all connected to the same WIFI network. DTU will collect the AC power
grid parameter by CT. If any power is exported to the power grid, DTU will send it to each
microinverter and control the output of the system.
This manual contains important instructions for PEEM-S100 DTU and must be read in its
entirety before installing or commissioning the equipment. For safety, only qualified
technicians, who have received training or have demonstrated skills can install and maintain
this DTU under the guide of this document.
Important Safety Information
During installation, testing, and inspection, adherence to all the handling and safety
instructions is mandatory. Failure to do so may result in injury or loss of life and damage to the
equipment.
Product Label
The symbols on the products are listed below and illustrated in detail.

System Introduction
The PEEM-S100 DTU is used in grid-tied applications which not allow electricity to be
transmitted to the public power grid, is comprised of three key elements:
 Projoy Microinverter.
 M-Cloud monitoring system.
 PEEM-S100 DTU.
The microinverter converts the DC electricity generated by solar panels into AC electricity
which is in accordance with the requirements of the public grid and sends the AC into the grid,
reducing the load pressure of the grid.
The microinverter is integrated with the Wi-Fi module and connects to the home Wi-Fi router
directly. Users can monitor the power generation of the system by M-Cloud monitoring App.
The PEEM-S100 DTU will detect the power to the public power grid. If there is an export to the
public power grid, DTU will communicate with the microinverter locally and reduce the
outpower of microinverters.

Check the Installation Environment and Position
When choosing the position of installation, comply with the following conditions:
Install the DTU near or in the home distribution box.
Avoid electromagnetic interference that can compromise the correct operation of electronic
equipment.
Use a mobile phone to check the Wi-Fi signal strength at the installation position. If the Wi-Fi
signal is bad, try to install the DTU in another position or move the Wi-Fi router.
Installation Steps
DANGER
·Only qualified personnel should install, troubleshoot, or replace DTU and accessories.
·Before installation, check the unit to ensure the absence of any transport or handling
damages.
·Unauthorized removal of necessary protections, improper use, incorrect installation, and
operation may lead to serious safety and shock hazards or equipment damage.
·Be aware that installation of this equipment includes the risk of electric shock.

Maintenance Guide
Routine Maintenance
Only authorized personnel are allowed to carry out the maintenance operations and are
responsible for reporting any anomalies.
Always use the personal protective equipment provided by the employer when carrying out
maintenance.
During normal operation, check that the environmental and logistic conditions are appropriate.
Make sure that the conditions have not changed over time and that the equipment is not exposed

Avoid temporary repairs. All repairs should be carried out using only genuine spare parts.
Storage and Dismantling
If the equipment is not used immediately or is stored for long periods, check whether it is
correctly packed. The equipment must be stored in well-ventilated indoor areas that do not have
characteristics that might damage the components of the equipment.
Take a complete inspection when restarting after a long time or prolonged stop.
Please dispose of the equipment properly after scrapping, as component parts are potentially
