What is a Solar Inverter?

Solar Inverter also being called Solar Converter, is a device invented to convert the DC power from the Solar Battery to AC energy to supply home appliances running.

A PV inverter (or Solar Inverter) is an inverter that converts the variable direct current (DC) voltage generated by photovoltaic (PV) solar panels into alternating current (AC) at the utility frequency, which can be fed back into the commercial transmission system or used by the off-grid system.

Solar inverters are an important part of the Solar array system’s balance of system (BOS) and can be used with equipment that is typically AC powered.

Solar inverters have special features that are compatible with PV arrays, such as maximum power point tracking and islanding effect protection.

Stand-alone inverters: Used in stand-alone systems where the PV array charges the battery and the inverter uses the battery’s DC voltage as the energy source.

Many stand-alone inverters also integrate a battery charger, which can charge the battery from an AC power source.

Generally, these inverters are not in contact with the grid and therefore do not require islanding effect protection.
Grid-tie inverters: The output voltage of the inverter can be returned to a commercial AC power source, so the output chord needs to be the same phase, frequency, and voltage as the power source.

Grid-tie inverters are designed with a safety feature that will automatically shut down the output if it is not connected to the power supply.

The grid-connected inverter does not have a backup power supply in case of a power outage on the grid. Battery backup inverters are special inverters that are powered by a battery, with a battery charger to charge the battery, if there is too much power, it will be fed back to the AC power supply.

This inverter can provide AC power to the specified load when the power supply of the grid is interrupted, so it needs to have the islanding effect protection function.

A solar inverter is another essential part of the home off-grid power system like Solar charge controller, solar battery, and solar panels.
