The Solar AGM line is tested to an eight-year design life under IEC 61427 standard for solar batteries and offers a three-year warranty for stationary applications. The non-spillable AGM design allows installers to customize the use and position of the batteries in customer applications, and means the units are certified for non-hazardous shipping under the US Department of Transport and IATA air transport regulations.

The cells use a robust proprietary paste, advanced plate design and premium separators for overall extended lifecycleIn addition and temperature tolerant, shock and vibration resistant and have a low internal resistance for higher discharge current and higher charging efficiency. This makes the batteries suited to harsh environments of off-grid as well as grid-connected systems with frequent cycling. The family runs from 1.3 to 2.46 kWh capacity. 

“As we continue to see strong customer interest and demand in applications such as residential storage (both off-grid and grid-tied), solar home systems, microgrids, remote telecom, as well as oil/gas, this new line of true deep-cycle Solar AGM batteries has been designed from the ground up and optimized for these types of solar applications and the need for frequent cycling in harsh environments,” said Ganesh Balasubramanian, director of new market development for Trojan Battery.

“Trojan continues to remain the only global battery manufacturer to engineer, and produce only deep-cycle batteries, and now we have leveraged our 90 years of deep-cycle flooded experience into engineering and manufacturing the best cycling AGM battery line batteries for solar applications worldwide.”

The battery family, built in the US, joins Trojan’s current Smart Carbon deep-cycle flooded batteries which feature Trojan’s proprietary carbon additive that helps reduce the effects of Partial State of Charge (PSOC) or undercharging which is common in renewable energy applications. Operating at PSOC on a regular basis can quickly diminish the overall life of a battery, which results in frequent and costly battery replacements.

“With batteries being one of the most expensive components of a battery-based solar system, it is critical to maximize the life of the battery bank to reduce the total cost of ownership of a system,” said Michael Grundke, general manager of EMEA for Trojan Battery. “The AGM line illustrates the company’s commitment to offering reliable energy storage solutions for a wide range of renewable energy market segments.
