A solar inverter or PV inverter, converts the variable direct current(DC) output of a photovoltaic (PV) solar panel into a utility alternating current(AC) that can be fed into a commercial electrical grid or used by a directly our appliances, or off-grid electrical network
inverters may be classified into three broad types
Hybrid Solar Inverters
A solar inverter main job is to convert DC power generated from the array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. This type of system solves issues renewable energy variability and unreliable power supply from Grid.
Grid-tie inverters Which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages. These systems are designed for Industry load where no need of backup power
Battery Backup Inverters Are special inverters which are designed to draw energy from a battery, manage the battery charge via solar charging with option of utility charging. These inverters are capable of supplying AC energy to selected loads during a utility outage.
