Batteries

Product Description:
RES can provide you with your batteries and supplies. From entire battery banks to keep your home running off-grid for extended periods to just a small bank for your RV, cabin or for furnace backup we are your premier source for everything battery related.
We are an authorized dealer and stocks a full selection of Rolls Surrette, Trojan, Discover Energy Systems, and Sun Xtender Deep-Cell AGM batteries. Stop in and see our extensive inventory of deep-cycle, lead-acid, and AGM batteries. Tools and tips for maintaining your batteries and maximizing their output and life are available in our store.
We also carry Lithium Batteries with a drastically longer cycle life over a lead-acid, 4-5x service life over lead-acid. This means you would get 5-7 years out of a lead-acid battery but would get 20 yrs out of lithium (keeping all other factors equal). Improved charge technology, halve your generator run time, reap the fuel savings! No maintenance, no fluids, no worries. Incredible energy density in a lightweight package.
Product Specifications:
- Energy Type: Battery Backup

Have questions?
What information does RES need to design a remote power system?
Useful starting information includes your project location, what equipment needs power, expected energy use, seasonal or year-round operation, existing electrical equipment, available generators or charging sources and your priorities for backup and reliability. RES can use that information to help determine what additional site assessment or system planning is needed.
Can solar be used on a boat?
Solar can contribute to battery charging and onboard electrical needs in marine applications. The appropriate system depends on the vessel, available installation area, electrical loads, battery system and other charging sources.
Does RES provide solar and battery systems for RVs?
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.
Can RES help with remote cabins?
Yes. Cabin systems can be designed around seasonal or year-round use, expected electrical loads, available renewable resources, battery storage and backup power requirements.
Can RES design power for a remote business or facility?
Yes. RES works with residential, commercial and remote applications and can evaluate renewable generation, battery storage, generator integration, electrical infrastructure, controls and ongoing support as part of a complete system.
Can an off-grid system include a generator?
Yes. Generators are commonly integrated with batteries and renewable generation in hybrid power systems. The system can be designed so each energy source supports the site’s operating requirements.
Do I need batteries for an off-grid solar system?
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.
Can solar work for an off-grid property in Alaska?
Solar can be part of an Alaska off-grid energy system, but system design needs to account for location, seasonal solar availability, electrical loads and the other energy sources available at the site. Battery storage and generator backup may also be incorporated depending on the application.
How does geothermal work?
A geothermal system uses underground loops and a heat pump to transfer natural heat between the earth and your building, providing highly efficient heating and cooling without generating heat.
Does RES handle permitting?
Yes, RES manages permits, inspections, and utility coordination.
