Externally associated repairs include isolators and power supply factors. Internal inverter repairs are often a sign that the inverter is approaching the end of its serviceable life, and continued, unrelated repair costs could be on the horizon.
Most inverters have layers of circuit boards affected by excessive heat during the energy conversion process. Over time, the heat breaks down the integrity of the delicate electrical components, which can almost result in a domino effect of failure in a reduced period of time towards the end of the inverter’s lifespan. A Bathtub curve effect aids in translating the end of serviceable life for inverter technology.
