Inverter Failure
Inverter Failure
A solar inverter is a mechanism takes radiant energy from the sun via the solar panels and converts or turns the radiant collected into usable energy for home appliances. Over the time, there have been common factors leading to inverter failure and understanding them may prevent you from having larger problems with your solar panel system in the future.
Poor workmanship and materials often result in water entry and damage to the inverter. This damage as a result of inferior products used throughout the installation, leakage of DC, water in the AC and DC enclosure, unsealed penetrations into any enclosures, DC breaker terminals corrosion, under –sized breakers, solar panels incorrectly mounted on roof, solar panels on roof incorrectly secured and are loose fixing, inverter and boxes mounted directly to building walls through self-tapping screws into the 2mm tin clapping, can cause or lead to more severe and deadly issues like electrocution and fire. Thus, we can, therefore, conclude from a vivid observation that cheap products can cost you more than they are worth, causing a serious threat to precious life.
Other causes of inverter failure are:
Improper Loading leading to Inverter Failure
Improper loading leads to damaged or defective fuses. Check fuses for fraying or obvious damage. In addition ensure breakers have not been tripped.
Fault Line is On but AC Load Not Working
A shutdown might have occurred due to an overload in the system surpassing the solar inverters surge capacity.
Reverse Polarity Connection on Solar Inverter
Incorrect battery connections damage inverters. To avoid having to replace the inverter regularly check battery connections, especially when they are due for replacement.
Inverter Failure due to Improper Disconnection of Loads
Check battery connections regularly to ensure the controller is receiving proper battery voltage. Batteries require replacement periodically.
Array Fuse Short Circuits
During connection, batteries might have been connected when a short circuit test was performed. For that, batteries should be disconnected in order to perform the test. The rating from the photovoltaic array may have surpassed the rating. So another controller in parallel should be added if there is a need or replace it with a controller that can able to accommodate the rating.
