2 PRODUCT OVERVIEW

The TrakMax solar charge controller is a 30 amp 12/24/48 Volt Maximum Power Point Tracking (MPPT)
photovoltaic (PV) battery charge controller. Through the use of MPPT technology, TrakMax can increase charge
current up to 30% or more compared to conventional solar charge controllers. TrakMax's sophisticated three
stage charge control system can be configured to optimize charge parameters to precise battery requirements.
The unit is fully protected against voltage transients, over temperature, over current, reverse battery, and
reverse PV connections. An automatic current limit feature allows use of the full 30 amp capability without
worrying about overload or unnecessary fuse blows from excessive current, voltage, or amp-hour based load
control.
Series pass Pulse Width Modulation (PWM) charge voltage control combined with a multistage charge control
algorithm leads to superior charging and enhanced battery performance. The filtered PWM power control
system uses highly efficient and reliable power MOSFET transistors. The MOSFET's are turned on and off at
high frequency to precisely control the charge voltage and the MPPT function.
Fully automatic temperature compensation of charge voltage is available to further improve charge control and
battery performance. The optional battery temperature sensor (purchased separately) is built for long term
reliability. The sensor element is environmentally sealed and encapsulated into a lug, which secures directly to
the battery. The TrakMax also includes an isolated RS485 port for connection to a remote monitor (purchased
separately).
For large system current applications (greater than 30 amps), multiple TrakMax units can be connected in
parallel.
