Product advantages

  • More stable distribution system

    The integrated solar energy storage power station can use energy storage systems to store energy at night. During peak electricity consumption, the energy storage power station and the power grid work together to provide power to households. This not only achieves peak shaving and valley filling, but also saves distribution and capacity expansion costs. At the same time, it can effectively solve problems such as intermittent and unstable new energy generation.

  • More efficient photovoltaic power generation

    The integrated photovoltaic storage system fully utilizes the power generation efficiency of the photovoltaic system during periods of sufficient sunlight during the day. In addition to supplying power to household appliances such as refrigerators, the excess energy is stored through energy storage batteries. During the peak electricity consumption period at night, energy storage batteries are discharged to generate energy without waste.

  • Higher cost-effectiveness of the system

    The integrated optical storage system will continue to develop towards higher integration, higher power density, higher conversion efficiency, higher security, and higher cost-effectiveness in the future. 

  • Increase phase power conversion device

    The equipment involved in power conversion in integrated optical storage can effectively reduce the size of the equipment and lower the cost of the system by increasing power density. The application of silicon carbide power devices in optical storage and charging systems will effectively improve the operational reliability and market competitiveness of related power conversion devices.

PRODUCT INTRODUCTION

There are two modes of household (household) optical storage systems: "spontaneous self use" and "spontaneous self use, surplus electricity connected to the grid". They fully utilize idle resources such as roofs and balconies, and the electricity generated can not only meet spontaneous self use, but also be sold to the State Grid. 

The system includes:

Photovoltaic modules: convert solar energy into direct current, charge the battery through an energy storage inverter, or directly convert it into alternating current to power the load.
Municipal power access module: connected to the AC input terminal, it can supply power to the load and charge the battery at the same time. If there is no connection to the main power supply or generator, the system can still operate normally. At this point, the load power is provided by the battery and photovoltaic module.
Integrated Energy Storage System: Zhongzi Photovoltaic Energy Storage Integrated Machine integrates energy storage batteries, integrating all components required for solar power generation into a compact unit, including inverters, batteries, and charging controllers.
Household loads: As external loads of the system, these loads can be connected to various household and office loads, including refrigerators, lighting fixtures, televisions, fans, air conditioning, and other AC loads.

SOLUTION

Household energy storage system

Provide various solutions for different roof areas. Standardized household solutions are mainly based on common flat and sloping roofs, and the operating modes are mostly spontaneous self use and residual electricity grid connection. The professional technical service team designs reasonably based on the customer's roof type to ensure the efficient operation of the customer's project. While endowing roofs with aesthetics, environmental protection, and technology, it also brings considerable economic benefits.
