Frequently Asked Questions
Which operating environments suit the VOLTRAGEN Voltra-40 best?
This unit is designed for industrial and commercial needs. With water-cooled operation and a prime rating of 40 kVA, it supports continuous and backup operation in facilities that need high reliability.
When should I use the prime rating and when the standby rating on this unit?
The 40 kVA prime rating applies when the generator is the main power source under varying loads, for example at sites without a stable grid supply. The 44 kVA standby rating is for backup during outages, with use limited to no more than 10% of total annual operating hours.
Is this unit available as an open frame?
All VOLTRAGEN units are built with a silent canopy, with noise below 80 dB at 3 meters. For open frame needs, choose a JERBINDO model of equivalent capacity.
What should I prepare before a consultation?
Prepare your estimated total load in kW or kVA, the operating type (prime or standby), the installation location, and your target operating date. This helps our team recommend the right unit.
