Gruber Power understands that key components within Uninterruptible Power Systems naturally degrade over time—jeopardizing system reliability if left unaddressed.
One of the most overlooked yet critical components are
electrolytic capacitors. These act as filters and have a limited service life. As they age, their performance quietly diminishes, placing increasing strain on the inverter section.
Unlike batteries, a failing capacitor may show no visible signs—but the impact is significant. As their filtering ability declines, the inverter is forced to work harder, accelerating wear and sometimes creating catastrophic and expensive failure.
Proactive capacitor replacement is essential to preserving UPS integrity and avoiding costly downtime.
Treat capacitors as the perishable commodity they are and plan on replacing them at or near the end of their rated service life.
