1. DDP Function
The DDP information collector is a device for Delta Solar Energy Monitor System to communicate with Delta PV micro inverter. This device monitors Delta PV micro inverters that are connected to the photovoltaic modules. The DDP collects energy and performance data from the PV micro inverter over in-home AC power lines and forwards that data to the Delta Solar EMS via the Internet for statistical reporting.
The Delta PV Micro Inverter system is a device that converts the solar panel DC output into grid-compliant AC power. This fully integrated device can maximize the modules' energy production by utilizing a sophisticated Maximum Power Point Tracking (MPPT) algorithm. This integrated system maximizes energy harvest and provides individual AC output without hazardous voltage. And in case of any failure of any individual solar panel or inverter, this will not impact other modules and inverter operations. Unlike traditional center inverter structures, this PV micro inverter system provides true redundancy and eliminates hazardous voltage levels.
The Delt a Solar EMS collects and analyzes the per-module data from each PV micro inverter. This system automatically detects any shortfall in energy production. It is easy for a repair technician to locate the failed solar module and perform the necessary replacement. It monitors and stores data on a constant basis. User can access the data for commercial or personal use.
The DDP is designed for easy installation and is easy to operate. User does not need any specialized equipment. It simply plugs to the grid tied wall AC outlet and routers for communications with the Delta Solar EMS. The DDP communicates with the individual PV micro inverters over the existing power lines in the residence or business.
After installation and device scanning, it assembles an internal database of all known Delta PV micro inverters at the site it manages. As a constant monitor, the DDP utilizes the customer’s site broadband router to forward information to the Delta Solar EMS. The DDP also reports any error conditions that affect the DDP or the PV micro inverters. You can view both energy data and error conditions in the Delta Solar EMS.

2. DDP Installation
Preparation
Before you install this device, first please check if the following items are included in the DDP package box. If there is any item missing, please contact your dealer for a free replacement:
z DDP Communications z Ethernet cable z Wi-Fi antenna z AC power cord z A kit of conical anchors and screws z Wall bracket z User manual
The following networking environment is required for install DDP:
z A reliable broadband internet connection z Web browser to view DELTA Solar EMS webpage z Router / LAN or Router/WLAN with Ethernet port (or AP Router with Wi-Fi
connection)
z Grid connected standard AC electrical outlet. Please do not plug DDP into a
transformer protection device like a power strip, surge protector, or un-interruptible power supply. These devices could block the communication signal.
Installation
Pick a suitable location to place your DDP device. W e suggest this location to be as close as possible to the wireless AP (if you have the Wi-Fi function) or the Service Panel (Load center). This DDP is designed to perform at an environment between
-10 degrees C to +40 degrees C that should cover the majority of indoor
environments.
Attention
Please call the installer if you have below conditions:
1. You are unable to understand how it works.
2. You notice any operation anomalies.
3. You don’t understand or fear that you can’t complete the fully install steps.
4. This device must be installed in rooms with suitable environmental conditions (see technical data).
DO NOT install outdoors.
5
5. Don’t equip to operate in environments that have particular flammability or explosive conditions.
For US Users:
See below PV micro inverter system installation instructions. After installing Data Collector, you can plug into 120Vac wall socket. In order to have good communication between Data Collector and PV micro inverter system, you should install a power line phase coupler(see below picture). It is an in-box passive circuit that couples power line signal for different phase of residential power line communication. After installation, you should set Internet Interface. See page 20 to finish all of installation.

Reallocating the DDP
If you ever lose power, or need to relocate the DDP to another location, just plug it in (if not already done) and let the DDP restart again. It will resume operation when power and internet connection are restored.
Attention
Please put DDP on the Recycle Bin because it can be recycling.

3. DDP Operation
Starting the DDP
After plugging the power cord, you will see the “Wi-Fi DEVICE” and “ETHERNET DEVICE” message display on the LCD of the DDP. It requires you to choose one device to be the data transmitter. If you do not have an AP router or Wi-Fi function, you only can choose the “ETHERNET DEVICE” option. Otherwise, the device will not operate.
After the initial setup, the system restores the default value or user setting. It will then display the IP address and Power in watts on the LCD after initializing is finished.
The LCD display will then change to become a calendar with power information after 10 sec.
> Wi-Fi DEVICE ETHERNET DEVICE
169.254.0.1 ID: 1 POWER:123.4W
00/00/00 00:00:00
Attention
If you do not choose a valid device, the display will remain on the device choice menu. The OLED fonts will disappear after user selects a device. If you would like to choose another transmitter again, you can select the “SYSTEM RESET” function of the menu or “Reset Button” of the slot to go to the initial step. Wi-Fi operates at a frequency of 2.4GHz that follows the IEEE802.11b/g communication standard. The 802.11g has a maximum raw data rate of 54Mbits/s and data access rate as defined in 802.11g. Sometimes, the RF signal decay or interference will be caused the data lose or DDP disconnection. So, please find the places which no interference or decay to let RF signal stable and strong. For WiFi compatible list, please refer the WiFi supplier web site.
ID: 1 POWER:123.4W

The Ethernet speed supports 10/100 Mbps. Please change router setting to support it if you use the 1000Mbps router. Our device can’t support the internet which has “Proxy” or “Firewall” and “ISP disconnect” to transmit the data. So, please kindly checking about these conditions if you meet the data can’t transmit to the server.
DDP MENU
The DDP has three buttons on the box labeled, “MENU”, “SELECT” and “DOWN”. The user can depress the “MENU” button to turn on the LCD Display (OLD) menu. Our DDP OLD menu includes the “OLED CONFIG”, “ DATE/TIMING SET UP”, “DST CONFIG”, “LCD DISPLAY CONFIG”, “SYSTEM RESET”, “RSSI DETECT”, “WPS (WiFi Protection Set up) START” and “EXIT MENU”. You can use the “DOWN” button to scroll the menus that are like interface menus (OLED/TIME) and SYSTEM MENU (RSSI DETECT/SYSTEM RESET/WPS START) and so on.

4. Troubleshooting
If you experience problems, some of them are described below. For system status and event message information, please see Event Messages on page 32.
Potential Problems and Solutions IP Address Problem:
If the IP address displayed on the DDP LCD does not match or you get the DHCP subnet from your internal network or AP router, it always shows “169.254.0.1”, it means it was unsuccessful to obtain a DHCP from your AP router. Check network connectivity to the AP router or other DHCP server. You may also wish to contact your Internet Service Provider or refer to your AP router documentation for assistance or setting.
Attention
WiFi signal strength will depend on user’s AP router distance. So, please possibly to set up our device near with your AP router to make sure RF signal have low decay or interference. You must change your AP router channel to others if you meet our device not easily to connection each other. If interference serious, it easily to meets this symptom.
