Float Charge @ 25°C: 13.7V
Bulk/Absorption Charge @ 25°C:
Set to 30 minutes every morning. Applied for 1
hour if the battery voltage drops below 12.3 volts.
14.1V 14.4V 14.4V
Manual Boost (Boost Button) max 30A @ 25°C:
Applied for 2 hours when boost button is pressed.
14.1V 14.4V 14.4V
Equalization Charge:
Applied for 2 hours every 28 days and if the battery
voltage drops below 12.1 volts.
N/A N/A 14.9V
All measurements assume +/- 0.1V tolerance.
If a charging cycle is unable to complete in a single day, it will continue the
following day. The terms SEALED/GEL, AGM and FLOODED are generic
batterydesignations.Choosethechargingprolethatworksbestwithyour
battery manufacturer’s recommendations.
Auto Equalize: The GP-PWM-30 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. Auto equalize is only available
for oodedbatteries.
Note
8.5 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) (14.1V for Sealed/Gel) right
away.
