You know the make, model, operating conditions and approximate working temperatureto be able to estimate this.
How many of them are there in an inverter?

An update.
Looking at the Wikipedia page here:
Varistor - Wikipedia, the free encyclopedia it seems you would need to know about the energy and frequency of the surges the varistor is likely to handle to estimate. Not so easy after all.
