Solar Inverters use power electronics technology to convert Direct Current (DC) energy from batteries or photo-voltaic (PV) panels (the sun’s energy) into Alternating Current (AC) energy to power AC loads. This AC energy (e.g. 230V AC singly phase) can be utilised to power ordinary AC-powered equipment and appliances, or fed into the national electrical grid where permitted. Solar inverters are critical components in solar photovoltaic systems and are available in a variety of sizes and functions. Some solar inverters have the solar charge controllers and battery chargers built-in. A solar charge controller such as a Maximum Power Point Tracker (MPPT), tracks the PV panel array’s output voltage and current to obtain maximum possible power from the PV array in any given environmental condition. While the battery charger controls both the charging and discharging of the batteries to enhance battery life.
