With increase in power demand globally the conventional energy resources are not able to meet the consumption requirements and there is a huge gap between energy production and demand. Therefore technology is moving towards non-conventional energy resources like Solar energy, wind energy, geothermal energy, wave energy etc. Out of all these resources solar energy is found in abundance and now technology has grown to convert the solar energy into electrical energy very easily with the help of Silicon based solar panels.
SOLAR PCU FEATURE/ UTILITY
S-PCU is a DSP/ Micro controller based Solar-Grid Power Conditioning Unit which is programmed with grid electricity saving features, elongated back-up time and PWM/MPPT charger possessing smart charging proﬁle for all types of batteries.
Solar Power Conditioning unit (PCU) is an integrated system consisting of a solar charge controller, inverter and a grid charger. It provides the facility to charge the battery bank through either a Solar or Grid/ DG set. The PCU continuously monitors the status of battery voltage, solar power output and the load. Due to constant usage of power, if the battery voltage goes below a set level, the PCU will automatically transfer the load to the Grid/ DG power and also charge simultaneously. Once the batteries are charged to the preset level, the Solar Power Conditioning unit cuts off the Grid/ DG Power from the system and restores it to feeding the loads from the battery bank while also returning to charging the battery from the available solar power. The PCU always gives preference to the solar power and will use Grid/ DG power only when the solar power/ battery charger is unable to meet the load requirement.
