If a charging cycle is unable to complete in a single day, it will continue the following day. The terms SEALED/GEL, AGM, FLOODED
and LFP (LITHIUM) are generic battery designations. Choose the charging prole that works best with your battery manufacturer’s
recommendations.
If PV power is insufcient or too many loads are drawing power from the battery, the controller will not be able to charge the battery
to the target charging voltage.
Auto Equalize: The GP-PWM-30-SB has an automatic equalize feature that will charge and recondition your batteries at least once a
month at a higher voltage to ensure that any excess sulfation is removed.
This mode should not be entered unless you are using a ooded battery.
8.4 MAXIMUM POWER BOOST TECHNOLOGY
TM
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.
To activate, hold the MAX BOOST Button for 3 seconds. As
long as there is full sunlight present, your battery voltage will
be boosted (to 14.4 VDC for Flooded, AGM and LFP; and 14.1
VDC for SEALED/GEL) for 30 minutes regardless of the battery’s
state of charge.
Icons Displayed: BOOST; Battery Symbol
In older controllers, the BOOST text icon will remain on until the
controller can maintain a Boost charge voltage for 30 cumulative
minutes. In newer controllers, the BOOST text icon will only ap-
pear while the controller is maintaining a Boost charge voltage.
IMPORTANT: Do not use the Maximum Power Boost function more than twice a day as it could damage your lead acid batteries due
to gassing. Sustained high voltages decrease lithium battery lifespan.
