Photovoltaic storage and charging integration solution

With the rapid development of energy storage, new energy vehicle and photovoltaic power generation industry, the photovoltaic storage charging integration solution has been gradually popularized. As the name suggests, it is an electrical device that, by using photovoltaic modules, converts solar energy into electric energy and then stores for vehicle charging. Generally, it consists of photovoltaic module, photovoltaic combiner box, photovoltaic storage charging machine, energy storage container, charging pile, etc. In response to the call of the nation, Zhiyuan Electronics has been engaged in photovoltaic energy storage in the new energy industry so early that it can empower customers’ product launch by providing a complete solution for the integrated application of photovoltaic storage charging.

Recommendation of system products

Photovoltaic module & combiner box

The photovoltaic module and combiner box are mainly used to convert solar energy into electric energy, and then gather and transmit the energy to the energy storage container. A photovoltaic module is composed of many photovoltaic panels and brackets, and their normal work generally depends on the wired/wireless networking. However, wireless networking is mostly used, compared with the cumbersome wiring and the high installation & maintenance cost of wired networking. In wireless networking, LoRa communication is gaining favor for its super strong communication capability.
ZSL42X LoRa SiP intelligent networking chip independently developed by Zhiyuan Microelectronics features high integration and simple development, which can facilitate photovoltaic networking.

Product features

  • Simple development, no need to develop complex networking protocols (such as built-in ad hoc networks, LoRaWAN).
  • Small size, high integration (only 11*11mm in size)
  • Support secondary development (built-in Cortex-M0+ core MCU)

Photovoltaic storage charging machine

The photovoltaic storage charging machine is used to store the power supply of photovoltaic combiner box in the energy storage container, while providing charging distribution management of these energy sources to safeguard the charging demand of the automobile. The EM series energy storage controllers independently developed by Zhiyuan Electronics feature rich interfaces and simple development, support special protocols such as IEC-61850/EC-104, and can meet the application requirements of various energy storage systems.

Product features

  • Support cloudy platforms (ZWS, Alibaba Cloud, Gizwits, etc.)
  • Stable and reliable (-40~+60℃)
  • Complete certification, sold at home and abroad (CB, UL, etc.)

Energy storage container

Energy storage container, as the name implies, is a container device for storing electric energy, and safety protection measures are necessary for the device because of the high energy density. The EPCM3568B-LI intelligent edge calculation controller developed by Zhiyuan Electronics integrates rich interfaces, and can accurately collect container data such as temperature, humidity, water immersion and air, providing a solid armor for your container security.
