The Best Solar Batteries

A battery is a critical component in a solar photovoltaic system.

U.S. Battery

Batteries maintain a constantly supply of electricity when photovoltaics are not active.Batteries maintain a constantly supply of electricity when photovoltaics are not active.
Solar batteries store DC energy generated from your solar system for use when the system is not actively producing energy from the sun, like overnight. These batteries power your electrical appliances in the interim. Batteries produced for solar systems are specially designed as deep-cycle cells, which are less susceptible than normal batteries to degradation due to continuous cycling.

U.S. Battery (usbattery.com) has been producing deep-cycle batteries since 1928 and is recognized in the industry as a company that stands behind its products. U.S. Batteries have "Diamond Plate Technology," which helps performance by providing a higher capacity, resulting in more watts per hour. Its solar batteries are also designed to handle substantial amounts of discharging and recharging every day.

Trojan Battery

The Trojan Battery Company (trojanbattery.com) has been one of the world's leading manufacturers of batteries for more the three generations. Trojan batteries are one of the most expensive solar-specific battery applications on the market, but their longevity and durability distinguishes them from other models. The Trojan solar battery contains Duragrid technology, which gives the battery an estimated 8-year life expectancy.

Universal Power Group

Universal Power Group (universalpowergroup.com) has been a leading supplier of solar batteries and power accessories for three decades. Universal Power Group's batteries are known for being highly efficient and long-lived, for both grid-connected and off-grid applications. The Universal Power Solar battery is a gel-sealed battery; this electrolyte gel technology is proprietary to the company. These batteries need no water additions, can be operated in any position and can be close to people and sensitive equipment. This battery provides higher cranking amps and a lower self-discharge than many other models on the market.

Interstate Batteries

Interstate Batteries (interstatebatteries.com) has been in business since 1950. It has grown to become one of the largest battery companies in the United States. The Interstate solar system battery uses an advanced chemical technology inside the battery cell designed to deliver more life cycles. This battery performs best in high heat and is vibration-resistant. The Interstate battery differentiates itself because of its four-post design, which makes installation easy and improves power flow.
