The Onick VP-6000 photovoltaic energy storage system integrates cutting-edge photovoltaic conversion, energy storage management, and intelligent power regulation technologies. Its precise operation ensures stable power supply in complex outdoor environments.
Photovoltaic Conversion: The Starting Point of Transforming Sunlight into Electricity
The system's solar panels, the core component of photovoltaic conversion, utilize advanced monocrystalline silicon technology and the photovoltaic effect to efficiently convert solar energy into electricity. When sunlight strikes the solar panel's surface, photons strike the monocrystalline silicon semiconductor material, stimulating electron-hole pairs. These electrons and holes are rapidly separated and migrate in different directions under the influence of the semiconductor's internal electric field, generating direct current (DC). Thanks to a nano-antireflective coating, the solar panel significantly increases its absorption rate across different wavelengths of sunlight, enabling it to stably capture and convert sunlight energy into usable electricity under all lighting conditions.
Energy Storage: Operation of the "Energy Warehouse"
The generated DC power is then transferred to a built-in lithium-ion battery pack for storage. The high-quality lithium iron phosphate batteries used in the VP-6000 play a key role in this process. During the charging process, current flows into the battery, releasing lithium ions from the positive electrode and then re-entering the negative electrode through the electrolyte, where the electrical energy is stored as chemical energy. The BMS (Battery Management System) monitors the battery status throughout the process, strictly controlling the charging voltage and current to prevent overcharging and over-discharging, ensuring safe and efficient battery operation and extending its lifespan. With a large capacity of 6000Wh, the VP-6000 can store sufficient energy to meet long-term power needs.
Power Output and Regulation: Intelligent On-Demand Power Supply
When powering external devices, the DC power stored in the battery first passes through the intelligent inverter, which converts it into stable AC power suitable for various common electrical devices. At this point, the system's control system begins intelligent scheduling, monitoring the load's power demand, the battery level, and the solar panel's power generation in real time. If the load's power demand is low and the solar panel is generating sufficient power, the system prioritizes solar power, storing any excess power. If solar power is insufficient, the control system automatically allocates battery power to supplement the supply, ensuring a stable and continuous power supply. When the battery charge drops below 20%, the control system automatically identifies the load type and cuts off non-essential power, prioritizing critical equipment and ensuring precise allocation of power resources.
Charging Modes: Multiple Power Supply Options Ensure Battery Life
The VP-6000 supports both AC fast charging and photovoltaic charging. With AC fast charging, after receiving the mains power, the current undergoes a series of processes, including rectification and voltage regulation, to rapidly charge the battery, typically fully charging it in about six hours. In photovoltaic charging mode, multiple 36V photovoltaic panels can operate simultaneously, with a maximum total power of 900W. In ideal, sunny weather, photovoltaic charging efficiency is comparable to AC fast charging, continuously converting solar energy into stored electricity, providing a flexible and sustainable energy supply for outdoor emergency backup.
