Photovoltic or Solar Power Inverters

21 Aug

Solar Panels (Including small wind turbines) produce DC electricity. DC Current is used to charge a battery bank in off-grid systems or sent directly to a grid tie inverter which feeds the electricity directly to the electric grid. A Solar Inverter, or PV Inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. Following types of inverters are most commonly used with PV Power System:-

Off Grid Solar Inverters

Off Grid Solar Inverters

  • Stand Alone or Off Grid Inverters. These inverters are primarily intended to be used with PV Energy for a home or business that is either totally disconnected from the electric utility company or it can also be used for providing emergency backup power to homes or businesses that currently use the power from an electric company. Inverters with the built-in AC charger option are particularly well suited to providing seamless backup power.

    Grid Tie Solar Inverter

  • Grid – Tie Inverters. These are the inverters connected to your electric utility company and do not use a battery bank. Grid-Tie Inverter systems tend to be lower in cost owing to the fact that they do not use batteries. However, if the utility company’s power goes down then your system will also shut down.

    Hybrid Solar Inverter

  • Hybrid Inverters. These inverters are primarily used for grid-tie purposes but also have the added feature that they provide backup power to your home / office when the electric utility fails. These are best for the places where electricity goes away frequently.
