Reliable Source Inc. has come to be one of the fastest growing companies in the international market and a leader in the power industry. With the opening of the RSI office in the US in January 1990, the company quickly became well known for its line of high end, reliable UPS systems. Likewise, beginning in 1993, RSI was notorious for its exports of high quality generator sets completing its commitment to providing a reliable source of power to its customers.

Reliable Source maintains a network of branch offices, distributors, and service centers in strategic locations around the world. Sales offices are staffed with knowledgeable personnel to help you choose the best generator set for your needs.

RSI service staff are factory trained and authorized to help troubleshoot, diagnose and solve operational problems, and assist in installation, maintenance, and repair. Our service stations are stocked with most commonly used, quality replacement parts, while our stocking locations located throughout the world have been positioned to offer a short delivery to your location on any other service part.

Reliable Source places great value on the establishment of long-term relationships with our customers, which becomes evident in the attention we give from generator set selection to production and from installation and maintenance.
