5.4 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 14.4V
(Flooded and AGM) or 14.1V (Sealed/Gel) right away.
To activate, hold the B Button for 3 seconds. As long as there
is full sunlight present, your battery voltage will be boosted (to
14.4V for Flooded and AGM and 14.1V for SEALED/GEL) for 30
minutes regardless of the battery’s state of charge.

Do not use the Maximum Power Boost
function more than twice a day as it could
damage your batteries due to gassing.
