48v DC Hybird Solar Home Energy System

System Composition

• Solar power generation part

  Reliable and efficient 48V DC hybrid home solar power supply system
  Stable power supply · Smart energy storage · All-weather protection

  Core component working description

   

  High-efficiency photovoltaic components
  Selected monocrystalline silicon solar panels effectively capture light energy and convert it into DC power. They can still maintain a power generation efficiency of more than 20% on rainy days, providing clean energy input for the system.

   

  Intelligent load control system
  Real-time monitoring of home appliance power fluctuations, automatic adjustment of current output, voltage fluctuations within ±2%, protecting precision electrical appliances from damage, and ensuring stable operation of TVs, refrigerators and other equipment.

   

  Wide-voltage DC conversion module
  Equipped with intelligent MPPT algorithm, the 12V/24V low-voltage DC generated by the photovoltaic panel is efficiently boosted to 48V, reducing transmission loss by 40%, and compatible with hybrid access of lead-acid/lithium batteries.

• 48V DC part

  1. Where does the electricity come from?
  ​​48V DC power supply is the basis of the whole system

  The main force is the solar panel, and the sunlight is directly converted into 48V DC
  When it is cloudy, it automatically switches to AC power and converts it into 48V DC through a rectifier
  Expanded compatibility with wind/hydropower generation (conversion equipment needs to be installed) Actual case: Mr. Wang's roof in Shandong has 10 photovoltaic panels, which automatically use the peak and valley electricity price period to store electricity on rainy days, saving 1,600 yuan per year in electricity price difference
  2. Only electricity can be stored reliably
  ​​48V dedicated battery pack is the key guarantee

  The abundant solar energy during the day is stored in the lithium iron phosphate battery pack (mainstream 48V 100Ah specification)
  Automatically releases power at night, supporting high-power equipment such as air conditioners to run for 3-5 hours
  Battery health manager function: Automatic balanced charging to prevent over-discharge User value: Ms. Li's home in Wuhan had 7 power outages last year, and the refrigerator and medicines were no longer scrapped due to power outages
  3. Intelligent distribution makes every kilowatt-hour glow
  ​​Conversion center determines system efficiency​​

  Inverter module: 48V DC → 220V AC, can drive 2.5-horsepower air conditioners
  Intelligent controller: real-time scheduling of three-way power supply (prioritize solar energy > battery > city power)
  Safety protection: automatic cut-off when voltage fluctuation exceeds ±5% Technical details: The conversion efficiency of the hybrid system is measured to be 91%-93%, 6-8 percentage points higher than the traditional system
