Electric Power Systems is a generator business that lists Bangor as its service area. The company says on its website that it works with off-grid homes that have generator backup and that it does maintenance, repairs and new installs, and it lists 24/7 emergency service. A Maine electrician license, MS20028817, held by JON W. JONES, is active on the state registry. On Google it holds 5 stars from 13 ratings. A 2025 customer with an off-grid solar system said the generator was not kicking in when the batteries drained, none of the contractors involved thought their part was at fault, and Jon Jones came out and figured it out. That 2025 customer wrote that they should have had Electric Power Systems do the installation from the beginning. A 2024 customer said Jon and his team installed a propane backup generator at their camp after frequent outages from mountain winds, and that the system had not failed them once since. A 2024 customer said Jon installed a whole house generator at their home in Enfield, which they heat with heat pumps and serve with a private well. A 2024 reviewer who manages generator systems said they were onsite with Jon to install a new Cummins generator and automatic transfer switch, and called his work methodical and efficient. A 2025 customer said Jon and the crew responded quickly to calls and emails and made sure customers understood the install process and how the generators work.
I have an off grid solar with generator backup. All very high quality equipment, yet very unreliable with respect to the generator kicking in when the batteries drained. There were many possible culprits. Were the wires from the start module of an adequate gauge? Did the propane line have sufficient length from the regulator to properly modulate pressure? Was the generator itself installed properly? None of the contractors involved felt as though their subset of the system was at fault. Jon Jones, although not involved in any part of the installation of the generator nor the propane nor the solar, came out and put his mind to it and figured it out. Paid attention to details that everyone else had missed. I should have had Electric Power Systems do the installation from the beginning.
Jon and the crew at EPS Maine are the best! They always respond quickly to calls and emails, answer all questions and make sure customers understand the install process and how the generators work. It’s rare to find a company that combines technical expertise with such genuine customer care. I wouldn’t hesitate to recommend Electric Power Systems to anyone looking for generator installation with top-tier support. Truly a 5-star experience!
Jon Jones and the crew at Electric Power Systems have been taking care of both my home and camp for years. The best part? If you ever run into an issue, they pick up the phone and will literally walk you through a storm until they can get out there! Their service is dependable, and their team goes above and beyond. Highly recommend!
Jon and his team are top notch - years of experience, impressive track record, and truly dedicated to exceptional outcomes.
I recently contracted Jon and his team at EPS of Maine to install a Propane back up generator at my camp. We were experiencing frequent outages because of the winds we get here in the mountains. Well since we have had the system it has not failed us once. In fact you dont even know when the power is out unless you happen to go outside and hear the generator running which is actually not loud at all. These guys are great ! I highly recommend them if you want a back up generator installed. Thanks Jon and Crew !, Don
