environment of high temperature and high humidity.
· By continuously checking solar panel power output changes, the controllers
employ multiple MPPT charge algorithms in combination to boost charging
eciency in dierent weather and temperature conditions.
· Built-in buer, allows max 25% exceeding rated power input.
· Industrial grade design with full range of electronic protections, like reverse
polarity protection for solar panels and battery wiring.
· Auto recognition of 12V/24V battery system voltage. Lithium battery excluded
from this feature.
· Charging modes available for most common deep-cycle battery types in the

1. Remove the magnetic covers. 2. Check and confirm the screwing condition
in the fixture surface, and tighten the screws
according to the instruction in the picture.
3. Check the fixture condition of the installation. 4. Put the magnetic cover back and clean the surface.

1. Unscrew the terminals completely, before inserting
any wiring leads.
2. Insert the bare wire side of the cable to the terminals
according to the right consequences.
3. Tighten the terminal screws as much as possible
Installation Remarks:
· Please make sure the battery wires would be connected first, and
then connect the PV wires.
· For dierent installation conditions and requirements, we may either
fix the controller first, then connect the wires, or we also may connect
the wires first before we fix the controller.
· If you need to re-wiring the device, please disconnect the PV side
firstly before loose battery cables.
The backlight in the screen will be on for 20 seconds with any button operation, or the screen
would enter stand-by/power saving mode.

12. Controller Specification
For example, the equalize charge voltage for a 12V FLD (Flooded) battery bank is 14.8V*1=14.8V. The
equalizing charge voltage for a 24V FLD (Flooded) battery bank is 14.8V*2=29.6V.
The variable “n” is adopted as a multiplying factor when calculating parameter voltages, the rule for “n”
is listed as: if battery system voltage is 12V, n=1; 24V, n=2.
