Auto Equalize: The GP-PWM-30-UL has an automatic equalize feature that will
charge and recondition your batteries once a month at a higher voltage to ensure
that any excess sulfation is removed.
This feature is only available when Flooded batteries are
selected.
8.4 Maximum Power Boost Technology™
Maximum Power Boost Technology™ (MPBT) allows you to override the normal
charging algorithm of the solar controller. MPBT is designed to be used before
the end of the day, if you know you will require many loads through the night.
This feature can also be used when you have just installed the solar controller, to
put batteries on a boost charge up to 14.4 VDC (Flooded, AGM and LFP) (14.1
VDC for Sealed/Gel) right away.
