Several
factors must be considered when choosing between a hybrid or stand-alone
configuration. Hybrid stations are sized to provide 25-75% of the load
requirements by the engine generator, resulting in a lower first-cost
for a given load. Stand-alone PV systems are sized to provide 100% of
the load and offer very low operating and maintenance costs. |

PV Hybrid Power Station Components Diagram A Typical Solar Power Plant / Power Station Consists of the following Components
4. Inverter/Battery Charger Microprocessor-controlled, high-efficiency sine wave inverter with three-stage, temperature-compensated battery charger. Peak conversion efficiency of 96%, protection circuitry, LCD display with user and setup menus. 5. DC Controller Solid state, low frequency, pulse-width modulated solar charge control with battery temperature compensation and automatic night time disconnect. 6. AC Distribution Panel Output AC breaker panel provides surge protection and flexibility for multiple AC load requirements. 7. DC Combiner Box Provides PV circuit disconnects and lightning/surge protection for electronic equipment. 8. Ventilator Fan Designed for active ventilation of hybrid battery enclosure to prevent accumulation of hydrogen gas. 9. Batteries Available in three battery types: economy flooded lead-acid, industrial flooded lead-acid and sealed lead-acid. Flooded lead-acid battery comes with recombiner caps to minimize water loss. Sealed battery available for maintenance-free performance. The control system maintains the batteries between 20% and 100% state of charge. 10. Battery Enclosure Sealed batteries are housed in a powder-coated steel, lockable enclosure with filtered vents. Flooded batteries are housed in an insulated, vented thermoplastic unit with lockable lid and drain plug. Designed to minimize battery temperature extremes, eliminate battery bank hot spots, prevent freezing and extend useful battery life. 11. Generator (Hybrid only) Commercial and Industrial engine generators available to meet requirements. Includes battery, alternator, remote start/stop contacts, self-contained protection and automatic safety shutdowns. Package includes weatherproof housing, vibration isolators on steel skid, flexible couplings, and replaceable dry element air filter. Propane and diesel fuel types available. 12. Structure Industrial grade, heavy-gauge steel coated with a durable hot–dip galvanized finish. Available in four configurations: ground mount, road trailer, off-road trailer and breakdown kit. |
