How Long Does an Inverter Last?
A good quality home inverter will be stable for 10-15 years, while a high load commercial system may need to be replaced between 5
An inverter battery lasts about 5 to 10 hours when fully charged. The backup time depends on the battery capacity and the load, which is the total energy consumption. You can use a formula or a battery backup calculator to determine the exact duration based on your specific voltage and usage. Next, identify the specifications of your battery.
Regardless of the size, the calculation steps are always the same. Using this calculation, a 24V inverter with a 100ah battery and 93% efficiency can run a 500W load for 2.3 hours. You have a 24V inverter with a 150ah deep cycle battery. The inverter is 93% efficient. You want to run a 700 watt load, so how long can the inverter run this?
The type of inverter you use plays a significant role; for instance, microinverters often have a lifespan of up to 25 years owing to their rugged construction and individual panel operation. On the other hand, string inverters might not last as long due to being affected by the weakest-performing panel in your solar array.
Tips for extending inverter lifespan include minimising exposure to extreme weather and maintaining optimal performance through regular checks and servicing. Remember that temperature has a profound impact on inverter longevity too—keeping your system cool will ensure it lasts longer.
