Thank you for choosing the ProStar MPPT charge controller
with TrakStar
TM
MPPT Technology. The ProStar MPPT is an
advanced maximum power point tracking solar battery char-
ger. The controller features a smart tracking algorithm that
finds and maintains operation at the power source's peak
power point, maximizing energy harvest.
The ProStar MPPT battery charging process has been
optimized for long battery life and improved system per-
