At Gennex Technologies, we’ve always engineered our inverters with long-term performance and protection in mind. One of the often-overlooked components we include—and strongly recommend installing—is the external capacitor, designed to be connected at both the input and output of the inverter.
Here’s a quick reminder of why these capacitors matter and why every installer should ensure they’re in place during setup.
Output Capacitors: Protect Against Voltage Spikes
When the load on an inverter changes suddenly—like during startup of motors or compressors—it can lead to transient voltage spikes. These spikes may damage connected appliances or stress the inverter.
Gennex includes output capacitors to absorb and smooth out these surges, protecting both the inverter and the end-user’s equipment.
Input Capacitors: Support Power Factor Correction
- At the input side, especially when grid or generator power is used, there can be issues with power factor—a mismatch between voltage and current.
- Input capacitors help correct this by balancing reactive power, improving efficiency, and reducing strain on the inverter.
Installer Action Point
Capacitors have always been part of the Gennex inverter system design. However, some installations miss them out—which can lead to reduced performance or avoidable damage over time.
Please ensure both input and output capacitors are properly installed, as per Gennex recommendations, to guarantee optimal system protection and long-term reliability.
