Why Battery Backup in Alaska?

RES offers many types of batteries for a wide range of applications, including lead-acid, absorbent glass mat, and lithium iron phosphate batteries. Batteries come in a large range of voltages, such as 2V, 4V, 6V, 12V, 24V, and 48V.

Applications include:
  • Remote power
  • UPS systems
  • Commercial and residential systems
  • Replacement batteries
  • Custom applications

Battery and Hybrid Generator Backup
RES designs backup power around the loads your operation cannot lose, the length of outage you need to ride through, and Alaska site conditions. Our team handles the energy audit, load calculations, system design, installation, commissioning, remote monitoring setup, and ongoing service, so one party is responsible for the complete system.

How RES Sizes a Commercial Backup System

  1. Energy audit and critical-load identification | We separate the loads that must stay on, such as refrigeration, servers, process equipment, and life-safety systems, from loads that can wait.
  2. Load calculations | We account for continuous demand and equipment startup loads, which often set inverter and generator requirements.
  3. Runtime target and generator integration | We agree on how long the facility must run through an outage and design battery storage, and generator integration where it fits, to meet that target.
  4. Site assessment, permitting, and utility coordination | We evaluate the installation location, access, and cold-weather conditions, and we handle permitting and utility coordination.
  5. Installation, commissioning, and support | We install and integrate the electrical system, commission it, set up remote monitoring, and provide ongoing service and support.

Who this is for

  • Businesses with refrigeration, servers, or production equipment that cannot tolerate interruption, including lodges, fishing and processing operations, and remote commercial sites.
  • Clinics, schools, and community facilities that need continuity for essential services.
  • Remote facilities where fuel logistics and service access shape the design.

What to bring to a project discussion

  • Outage history at the site, including how often and how long.
  • A list of critical equipment and its power requirements.
  • The runtime your operation needs.
  • Site access details and any existing generator or electrical setup.

Testimonials

Learn why customers from over 200 locations across Alaska trust RES for their renewable energy needs.
"When our old inverter died Fred was extremely helpful. He was patient and articulate in teaching us how to program and use our new system. It was so refreshing to have an actual person on the phone. A big thank you to Fred. Your patience was appreciated."

Battery Backup FAQ

    • 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.

    • Yes. RES works with RV and mobile power applications. System design can account for available installation space, expected loads, battery capacity and available charging sources.

    • Most fully off-grid solar applications require some form of energy storage or another source of power for times when solar generation cannot meet the load. The appropriate battery capacity depends on energy use, desired autonomy, seasonal conditions and the overall system configuration.

    • Yes, systems are designed around the customer‚ critical loads and needs.

    • Battery backup is quieter, requires no fuel, and has lower maintenance.

    • Battery systems switch to backup power within milliseconds of an outage.
