Find by power output
Diesel generators by kVA.
Compare the power class you need, then check each model’s exact prime and standby output. kVA pages include close alternatives where the requested number falls between documented ratings.

Prime or standby?
A generator can have different prime and standby ratings. Select against the rating appropriate to how it will operate, then assess starting loads and site conditions.
