Solar Inverter

A hybrid inverter is better than a conventional solar inverter as it combines the function of solar inverter and battery inverter to one equipment.

The direct current (DC) electricity generated by your photovoltaic (PV) system is changed into the alternating current (AC) electricity that is used to power your home. This type of solar grid-tie inverter also makes it possible to send any excess electricity generated to the utility grid.

Size of solar inverter dependent on the equipments that are intended to be used while utility supply is down. Total load on inverter is equal to the sum of all nameplate rating of such equipments. While sizing, some equipment like air conditioner and refrigerators should be sized at 2/3 times normal rating to account for the high inrush current drawn by these equipments while starting. An additional 25 -30 % can be considered as buffer for future expansion.

Once the total wattage of devices are calculated, the next step is to determine the type and number of batteries required to support your inverter. The battery capacity, measured in ampere-hours (Ah), is crucial for ensuring your system can store enough energy to meet your needs, especially during power outages or when solar input is unavailable.
