JDSOLAR solar off-grid system is suitable for some remote island areas and sparsely populated mountain areas. Due to the high cost of power grid deployment, the power supply cannot be fully covered yet. In order to solve the problem of electricity consumption, diesel generators are generally used for power supply.
Diesel engine power generation must not only consider the cost of fuel itself, but also the storage, transportation and noise and safety aspects of the system are inevitable problems. However, in the above scenarios, the application advantages of photovoltaic off-grid energy storage systems are very obvious. There is no series of problems caused by fuel supply and operating noise of oil engines, and the cost of photovoltaic energy storage systems is also highly competitive. At the same time green.
JDSOLAR solar off-grid system is simple in structure and easy to install. Compared with a system composed of a single MPPT controller and battery inverter, the equipment cost is lower, the operation is more stable, and the overall efficiency is higher.
The model adopts a fully modular design, supports hot swapping, and is easy to expand. Each module can be used as an independent MPPT controller, which can adapt to complex component installation terrain and minimize the loss of power generation caused by shadow occlusion and barrel effect. If a fault occurs during the operation, it will only cause the corresponding module to operate, which will not affect the normal use of other modules, and will not cause a large-scale downtime. It is more convenient for maintenance and replacement.
The built-in power frequency isolation transformer has more powerful loading, impact resistance and stability. In addition, because the AC and DC sides are completely isolated, there is a reliable guarantee for personal and equipment safety during the use of the equipment.
It supports commercial power and oil machine as backup access.
