_______________________________________________________________________

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 appear 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.

If sunlight is insufficient or not available, completing Max Power

Boost may take much longer than 30 minutes from the time of

the button press. Max Power Boost and the BOOST icon cannot

be turned off by pressing the Max BOOST button.

8.5 Viewing the Controller Display Information

GP-PWM-30-UL has two

modes to watch the display

information, manual and auto

scroll.

You can change between the

two modes by holding down

the A Button for 3 seconds.
