GP-PWM-30
________________________________________________________________________
Maximum Power Boost Technology™
Maximum Power Boost Technology™ (MPBT) is a new feature on the
GP-PWM-30 that allows you to override the normal charging algorithm of
the solar controller. This feature will make the GP-PWM-30 go into a
boost mode, bringing the voltage up to 14.4 VOC for 30 minutes
regardless of the batteries state of charge. This feature should not be
used more than twice a day as it could cause your batteries to require
more distilled water top-ups due to more gassing of the batteries.
MPBT is designed to be used before the end of the day if you know you
will require a lot of loads through the night. The MPBT feature can also
be used when you have just installed the solar controller, to put batteries
on a boost charge up to 14.4 right away.
IMPORTANT: Do not use the Maximum Power Boost function more
than twice a day.
To activate the Maximum Power Boost
Technology™, hold the A Button for 5
seconds to put Controller into Max.

sunlight present, your batteries
(flooded only) will be boosted to 14.4V
for 30 minutes
