Why we recommend Triton Power

Triton Power is our value brand for mobile and portable diesel generators, and an emerging option for industrial standby. When MQ Power's pricing is a stretch or lead times are too long, Triton delivers comparable capability at a lower price point with faster availability.

We are developing our Triton Power sales relationship and building fleet experience. Every engine platform Triton uses — Perkins, John Deere, Kubota, Scania, Volvo — is one we already service daily across other brands. Triton's open architecture means our technicians can maintain these units with standard tooling and widely available parts.
