Internal Temperature Protection
• When the internal working temperature reaches 85oC, the unit will
stop the charging process. The LCD backlighting will flash and an
Over-Temperature icon will indicate.
• When internal working temperature reduces to 65oC charging
will restart at full capacity.
Battery Temperature
• External temperature detection and display is activated once the
5m temperature probes provided are correctly connected to the
solar controller and battery.
• When battery temperature reaches at 65oC, battery protection
kicks in, charging stops and the display will begin to flash.
• Charging will restart when the battery temperature drops down to
45oC.
• Warning: when any type of Lithium battery is connected to the solar
controller, it is MANDATORY to connect the provided temperature
probe/probes between the solar controller and each battery. The
charging process will not start whilst the temperature
sign “—” flashes blank.
Single Regulator Current Rating Modification:
• Press and hold Down Arrow for 5 seconds to display ‘current
rating’ and enter amperage setting mode;
• Once in Amperage setting mode, quick press Down Arrow to
change current from higher ratings to lower ratings. For instance, a
20A rated unit can be set at 10A, or 5A; a 10A rated unit can be set
at 5A. The controller will not be able to be set at a lower amperage
rated unit to a higher amperage. For instance, a 10A unit cannot be
set as 20A; a 5A unit cannot be set as a 10A or 20A unit.
• Press and Hold Down Arrow for 5 seconds to confirm setting and
exit amperage setting mode.
• Throughout this process, press any key to exit without saving
changes.
Safety Protection Features
• The smart programming of each solar controller prevents a battery
from being overcharged.
• This solar controller is built with polarity protection
• This solar controller has short circuit protection.
• This solar controller prevents over-current charging.
• It is strongly recommended that a 45A fuse to be connected to
solar panels and batteries. The solar controller protects itself, but
not the solar panel and battery connected to it. Once Input and/or
Output current reach 45A, the solar controller will “burp” at 50Hz
until the short circuit and/or overcurrent issue is fixed.
• This solar controller prevents current flowing back from batteries to
solar panel.
• This solar controller provides temperature protection. It will stop
charging and flashes its LCD display backlighting when working
temperature reaches 85oC. Charge process resumes when
working temperature drops down to 65oC, backlighting stops
flashing.
• This solar controller and its temperature probes protect batteries
by ceasing the charging process when the battery temperature
rises to 65oC, backlighting and Over-temp will flash.
• Charge process restarts when battery temperature drops down to
45oC. This solar controller permanently stops the charging process
when the battery reaches 65oC for the third time.
• Warning: when any type of Lithium battery is connected to this
solar controller, it is MANDATORY to connect provided 5m
temperature probe/probes between the solar controller and each
battery, and ensure that the correct battery chemistry type has
been selected to avoid battery damage or explosion.
