Have questions?

    • RES works with residential, commercial, and remote applications and can evaluate storage, generator integration, electrical infrastructure, controls, and ongoing support as one system.

    • Alaska temperatures affect battery performance and charging, so siting, enclosures, and heating are part of the design.

    • Batteries carry loads instantly and silently, while a generator extends runtime when the outage outlasts stored energy.

    • Runtime depends on the critical-load profile, battery capacity, and whether a generator or solar recharges the system. RES designs to a runtime target agreed with the facility.

    • RES starts with an energy audit and load calculations to separate critical loads (refrigeration, servers, medical or process equipment, life-safety lighting) from loads that can wait. The critical-load list drives battery capacity, generator size, and the electrical integration design.

    • Contact RES with your project location, facility type, current energy sources, approximate energy requirements, and operational goals.

    • Yes. RES provides operations and maintenance services, including monitoring, preventative maintenance, battery testing, troubleshooting, repairs, and system upgrades.

    • Renewable energy may help reduce electricity purchases, fuel consumption, or exposure to changing energy costs. Actual financial benefits depend on system design, energy demand, utility rates, fuel costs, project location, and installation expenses.
