Experience with various systems

QE Solar has experience working on AC/DC coupled solar energy storage as well as stand alone systems. Experience with commissioning, testing and troubleshooting various BESS, PCS and SCADA systems.

Understanding of customer and utility needs

Each BESS installation is unique in terms of utility interconnection, use of power and possible restrictions of charging and discharging. Through years of experience QE solar has come to understand and work within these constraints to provide the best service possible.

Full BESS service from design & installation
to operation

Offering a wide variety of BESS related services, QE Solar is uniquely qualified to service BESS projects throughout its life cycle. From installation to operation, a BESS requires a number of services. As the life cycle of the system progresses, so do the services required to maximize uptime and increase return on investment. QE Solar’s extensive and experienced field service team is available every step of the way to provide the required field action.



Acting as a manufacturer’s representative, QE Solar regularly commissions numerous large and utility scale BESS projects providing pre-commissioning inspections, initial equipment energization, programming, and BESS capacity testing to seamlessly transition into BESS operation.

Troubleshooting and Repairs

QE Solar’s team of engineers, electricians and technicians provide comprehensive troubleshooting and repairs to all manner of systems that make up an energy storage system. Including but not limited to: BESS, PCS, HVAC, protective relay, monitoring and control systems.

Witness Tests

Working with local utilities to demonstrate the correct operation of protective devices, PCS ramp rates and response to varying utility conditions. Completion of utility witness tests are crucial to securing permission to operate.

Consistent Maintenance & Testing


Routine BESS maintenance ensures uninterrupted operation and peak system performance. Equipment maintenance combined with field service reports safeguards manufacturers warranties.


Performing thermal imaging of electrical connections and providing corrective action is one of the leading ways to prevent failures and keep equipment operational. Routine BESS capacity tests indicate the overall system health and condition of the batteries.
