Deep-cycle absorbent glass mat (AGM) batteries specifically designed for solar and other renewable energy applications are now available from Trojan Battery Company (Santa Fe Springs, CA).

The initial release includes a wide range of Trojan Solar AGM models with a three-year warranty for stationary applications. The company says that with its non-spillable design, the new Trojan Solar AGM batteries – tested to an eight-year design life under the IEC 61427 standard for solar batteries – enable installers to customize the use and position of the batteries in customer applications.

This battery family joins Trojan’s current Smart Carbon™ deep-cycle flooded batteries which feature a 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.

The company’s solar battery line incorporates a range of advanced technical features including a robust proprietary paste, advanced plate design, and premium separators for overall extended lifecycle, and is optimized for total cost ownership. The new deep-cycle Solar AGM batteries are temperature tolerant, shock and vibration resistant, and have a low internal resistance for higher discharge current and higher charging efficiency. These features make it the ideal battery for the harsh and demanding environments of off-grid as well as grid-connected systems with frequent cycling needs.
