Product introduction

OneHo grid-2.1 connected photovoltaic system
OneHo roof photovoltaic system consists of micro inverter, Gateway and cloud  monitoring platform. The system architecture is shown below

Micro-inverter: OneHo micro-inverter as part of the photovoltaic power generation system, the output of the photovoltaic module of the dc-efficient conversion to meet the requirements of the AC power grid for household load or feed into the grid.
Gateway: OneHo Gateway is a communication device that connects the operation data of the Solar Module and the micro inverter to the cloud monitoring platform. It collects the production and performance data of the micro inverter through the PLC power line and uploads it to the network, to achieve remote monitoring and management.
Web monitoring platform: it is a Web-based energy management portal that allows you to view PV system details, manage systems, and resolve system problems.
App: a mobile App for iOS and Android devices that allows users to view PV system performance data at any time, mIT Fernen Konstruktionen, Schnelle

Gateway EQ-MU-Pro

Product features

• The EQ-MU-Pro communicates with the micro-inverse in the system through PLC Power Line, collects all the running data and status of the micro-inverse in the system, and is also responsible for transmitting the control command to the micro-inverse in the system to adjust the running state of the system, to achieve system maintenance. One EQ-MU-Pro can be networked with up to 250 micro-inverters.
• EQ-MU-Pro supports Ethernet, WIFI and 4G modes to connect to the Internet to achieve information exchange with wanhe cloud monitoring service platform. Send the running data and status of all micro-inversion in the system to the WANHE Cloud Monitoring Server, and also be responsible for sending the system control command and data of the cloud monitoring server to the micro-inversion in the system, realize the remote operation and maintenance of the system. Real-time detection of network status, automatic switching of communication mode, priority to ensure the quality of communication, while reducing communication costs, complete data upload and send.
• Once you’ve installed and networked the EQ-MU-Pro, micro-inverter, you can access the Web or APP to monitor and manage the device.
  One side of the EQ-MU-Pro communicates with the MI via PLC power lines, and the other side communicates with the cloud via wired or wireless networks.
• The communication topology between EQ-MU-Pro and external devices is as follows:
