Trojan Battery Launches Smart CarbonT Line of Advanced Lead Acid Batteries Smart Carbon Designed to Improve Battery Performance in Partial State of Charge

Trojan Battery is the first manufacturer to introduce a carbon additive as a standard feature in its deep-cycle flooded batteries used in RE, inverter backup and telecom applications.

SANTA FE SPRINGS, Calif., Jan. 16, 2014 - To address the impact of Partial

State of Charge (PSOC) on cycling batteries in renewable energy (RE),
inverter backup and telecom applications, Trojan Battery Co. today announced
the addition of Smart CarbonT as a standard feature to its Industrial and
Premium flooded battery lines.

Smart Carbon is a proprietary Trojan formula which provides improved
performance when the batteries operate in PSOC, enhancing overall battery
life in off-grid and unstable grid applications where the batteries are
under charged on a regular basis. Along with increased life in a partial
state of charge, Trojan's Smart Carbon proprietary formula also provides
improved charge acceptance and faster recharge in PSOC applications.

As the world's leading manufacturer of deep-cycle batteries, Trojan
understands that batteries used in harsh RE, telecom and inverter backup
systems are regularly cycled at PSOC due to the intermittency of solar
generation, an unstable grid or to minimize operating costs of a hybrid
Charge-Discharge-Cycle (CDC) system. Operating at PSOC can quickly diminish
the overall life of a lead acid battery, which results in frequent and
costly battery replacements. With batteries now being one of the most
expensive components of these systems, it is critical to maximize the life
of the battery bank in order to reduce total cost of ownership. To address
the issue of PSOC, Trojan's engineering team developed the Smart Carbon
advanced lead acid formula to enhance life and performance of Trojan
batteries operating in PSOC.

"Trojan Battery is the first manufacturer to introduce a carbon additive as
a standard feature in its deep-cycle flooded batteries used in RE, inverter
backup and telecom applications. Trojan's engineering team has spent more
than five years in research and development experimenting with many types of
carbon to ensure the right formula to successfully address PSOC," said Bryan
Godber, senior vice president of global market development at Trojan
Battery. "While most carbon additive research has focused on VRLA batteries
for start-stop automotive applications, Trojan's focus has been on the
addition of carbon to deep-cycle flooded batteries for stationary
applications in off-grid and unstable grid locations. Trojan is committed to
these market segments and will continue to be an innovative leader in the
energy storage space."

Trojan chose to add Smart Carbon first to its deep-cycle flooded batteries
because flooded technology is the most widely used in off-grid and unstable
grid applications globally due to its cycling performance, ability to
withstand harsh conditions, widespread availability and economical price

Challenges of Partial State of Charge

PSOC is a reality for most off-grid and unstable grid RE systems since solar
panels used in these applications are frequently undersized, resulting in
the consistent undercharging of the battery bank. The same is true due to
intermittent weather conditions or placement of solar panels in shady areas,
which affect the solar panels' ability to collect and store enough energy to
fully recharge batteries.

PSOC also is common in inverter backup systems where batteries are used when
the grid goes down. Because the grid in many regions of the world goes down
several times a day, or is only available a few hours a day, deep-cycle
batteries are under charged on a regular basis, resulting in diminished life
of the battery.

Telecom applications which operate off-grid, rely on an unstable grid, or
depend on a hybrid RE/battery CDC system for power face the same PSOC issues
as does solar. The same is true for hybrid telecom applications that are
powered by diesel generators, which serve as the main charging source for
the battery bank. In many diesel generator installations, the system is
often set up to leave the batteries in a partial state of charge in order to
minimize fuel costs, once again resulting in batteries operating in PSOC
conditions and shortening the life of the battery bank.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
