GenStar MPPT
2.1 Overview
Thank you for choosing the GenStar MPPT charge controller with TrakStar
TM
MPPT Technology. The
GenStar MPPT is a maximum power point tracking solar battery charger. The controller features a
smart tracking algorithm that finds and maintains operation at the power source's peak power point,
maximizing energy harvest.
The GenStar MPPT battery charging process is designed for long battery life and improved system
performance. GenStar MPPT is compatible with Lithium, Lead-acid, Ni-Cad and Flow battery
systems. Self-diagnostics and electronic error protections prevent damage when installation mistakes
or system faults occur. The controller also features several communication ports, and terminals for
remote battery temperature and voltage measurement. See ReadyBlock BOS Components in
Section 2.5 for details on data interface capabilities.
