OFF-GIRD SOLAR INVERTER Boost, Isolation and Sinusoidal Waveform Generation by Power Frequency Transformer

SY300/24-220ZB inverting controller has no built-in battery box and external battery box will be required.  SY300/24-220Z series inverting controller is a new generation of specialized power supply equipment for solar power system. It is specially designed and manufactured for solar power system with the integrated functions of charge-discharge control and inverting control as well as perfect control and protection functions. Adopting power frequency transformer for isolation and boost, AC220V sinusoidal voltage is supplied as the output to meet the requirement of high quality and reliability power supply for equipment.    With MOSFET (made by US Fairchild Semiconductor Corporate) and Microchip signal processor have been built in the main circuit, this power supply has the features of high inverting efficiency and stable output voltage. This power supply is designed with various protective measures such as DC input overvoltage and under-voltage protection, reverse polarity protection, overload and short circuit protection for AC output to ensure the technical and reliability data to be met.

Application SY300/24-220ZB inverting controller will form a stand alone solar power system added with PV module and battery to generate power wherever having sun irradiation. The system can be used as utilities in the following places:      a)    Remote mountain area, unattended frontier defense and island;      b)    Communication base station and field operation;      c)    Power demonstration project, landscape lighting, street light and billboard lighting;      d)   Expressway, unmanned area lighting, camera shooting and telephone;      e)  Oil field power supply for oil extraction equipment.
