Power conditioning unit:- As SPV array produce direct current electricity, it is necessary to convert this direct current into alternating current and adjust the voltage levels to match the grid voltage. Conversion shall be achieved using an electronic inverter and the associated control and protection devices. All these components of the system are termed the "Power Conditioning Unit (PCU)". In addition the PCU shall also house MPPT (Maximum Power Point Tracker). Inverter output should be compatible with the grid frequency. Typical technical features of the inverter shall be as follows:- Rated Power-230V 1 Phase 50Hz, Maz supported Panel Power-8000WP/*KW, Charge controller- MPPT, Nominal bank battery voltage-96V (supports 8/16 batteries) minimum batteries bank 1200 AH Intelligent system with 32 bit DSP controller which enables it to handle multiple algorithms efficiently. Inbuilt MPPT charge controller extracts upto 30% more power from panels. Inbuilt isolation transformer to protect from grid surge and noise. Selectable source priority- Choose source priority from solar, battery and grid Userfriendy informative LCD display for time charging, supply etc. Dual MCB protection against short circuit protection for AC & DC. Safe for your home with comprehensive protection features such as short circuit, reverse polarity, battery over-charge and battery deep-discharge. Pure sine wave output for safety and noisless operation of connected appliances. withstand ambient temperature range 0 deg to 55 deg. withstand ambient humidity range 5% to 90% condensing. Includes system for surge protection. Lighting protection, earthing protection etc. (Compliance to most of the National & International standars for safety and efficiency and reliabilty e.e.
