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 Delta 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.
