While solar panels are very popular, the quality of the solar inverter is always overlooked when people are buying solar power package.
A solar inverter is a special box situated away from the panel array that converts the solar panels direct current to alternating current electricity, which is suitable for use by all house appliances and feeding into the main grid.
The solar inverter can be subject to varying voltage levels, the extreme range of temperature, moisture, and dust. Of all the solar components, the inverter is the key to the safety, reliability, efficiency and usability of the solar panels systems.
Just as when it comes to solar panels, not all inverters are the same even when the manufacturer makes claims of producing high-quality units. You should know that poor quality inverters can impact profoundly on the performance of your solar panel power. Also, it can have a high failure rate and can pose an electrical safety threat.
Poor quality solar inverters will feature poor seals, shoddy circuits, and may also heat up more than what a good inverter can, and all these can impact the efficiency and serviceable life of the unit. A heat test done by solar experts involving the use of thermal imaging camera shows that the temperature difference between two inverter brands can be considerable. Therefore, it is always to get the best brands.
What to consider when selecting a solar inverter
IP rating – this is the ability of the inverter seals to prevent water and dust ingress. Although most inverter manufacturers claim high IP ratings suitable for outdoor installations, the location and quality of the seals and ventilation will significantly affect the ability of the solar inverter to outlast many years the solar power systems are expected to work.
Peak efficiency – this represents the energy ability that the inverter can achieve.
Solar inverters represent a good percentage of the cost of the system. With consumer attention often on the solar panels in a solar power package, some manufacturers tend to cut corners on the inverter quality to boost profits and reduce system prices.
While poor shoddy inverters may feature the same duration of warranty as the quality counterparts, the inconveniences of making a warranty claim should be considered when making a purchase. This is because you might find that making a warranty claim from the manufacturer takes too long, and many will opt to buy a new inverter instead of facing the power inconveniences. Therefore, when purchasing the solar inverter, be careful from which supplier and brand you are obtaining the products to be sure of getting good results and reliable solar power.
