Redundant solar inverter

What does a solar inverter do?

First, let's clarify the role of an inverter. Solar panels generate DC power, while household appliances operate on AC power, as supplied by the electricity grid. The primary role of a solar inverter is to convert DC solar power to AC power.

Should I install multiple inverters on my solar power system?

Installing multiple inverters on your solar power system has numerous advantages: Allows for split-phase connection to the load control panel Allows for modular expansion of the solar power system hardware Let’s review how to plan your solar system for modular development and built-in redundancy.

What happens if a single inverter fails?

A single inverter in the system will result in the entire system going out of operation when the inverter fails. Having two or more inverters in the system provides the redundancy required to allow one inverter to fail or be serviced with no adverse impact on the AC power supply to the loads.

Is a solar inverter a converter?

A solar inverter is really a converter, though the rules of physics say otherwise. A solar power inverter converts or inverts the direct current  (DC) energy produced by a solar panel into Alternate Current (AC.) Most homes use AC rather than DC energy. DC energy is not safe to use in homes.

What happens if you run an inverter at peak output?

Running an inverter at peak output for extended periods will lead to overheating the components and the cooling fans running continuously, leading to premature failure. Inverters have a much shorter lifespan than solar panels, charge controllers, or battery storage systems and will thus fail first during the system’s operational life.

How efficient is a solar inverter?

These days, most inverters are 96% to 99% efficient. The minimum and maximum voltages (expressed in DC) provide a voltage level range at which your system can input solar energy from your panels to your inverter. The wider the range, the better your inverter can perform in more extreme conditions.
