What is the lifespan of a 20kw PV inverter
Oct 19, 2023
The lifespan of a PV inverter depends on the shortest-lived component in the inverter - the electrolytic capacitor. Electrolytic capacitors have electrolyte in them, which will evaporate and dry out over time, leading to an increase in the equivalent series impedance of the electrolytic capacitor, and when the current is the same, the higher ESR will cause the capacitor to heat up, which in turn will exacerbate the evaporation of the electrolyte, and ultimately lead to the failure of the device.
Generally speaking, the life of 20kw PV inverter can have 8-15 years. We can make the life of the inverter as long as possible by standardized use.
1. Do not place the inverter in a closed space. Closed space is not conducive to heat dissipation, high temperature will reduce component performance and life.
2. If the inverter is installed outdoors, avoid sunshine and rain.
3. When multiple inverters are installed together, there should be a gap of at least 20 centimeters between the inverter and the inverter, so as not to affect each other's heat dissipation.
4.20kw photovoltaic inverter belongs to high-power inverter, installation and daily use should also avoid excessive knocking, collision, avoid frequent overload and short circuit, wiring positive and negative poles should be correct.
Wanhos' inverters utilize the latest technology and design to provide high quality, high efficiency, long life and low noise. Inverters are one of the essential components of solar panels, capable of converting direct current into alternating current for domestic and commercial use, and Wanhos inverters are manufactured in accordance with strict standards such as ISO and CE certifications to ensure product quality and safety.
