CONNECTIONS:
1. Always connect the baery rst, then solar panels. This is to prevent a voltage surge or spike from
damaging the sensive electronics in the charge controller.
2. Connect the solar panels second.
23V maximum solar panel Open Circuit Voltage (VOC) input for charging 12V baery/baeries.
46V DC maximum solar panel Open Circuit Voltage input (VOC) for charging 24V baeries.
See “Specicaons” for more details.
3. If applicable, connect “load” last.
4. Reversing the polarity will result in a damaged charge controller and will void the warranty.
Menu buon: short press to scroll through sengs. Long press to modify sengs.
Up buon: Short and long press does nothing from home screen. Use to adjust sengs
aer long pressing the menu buon.
BUTTON GUIDE:
Down buon: Short press turns on/o the “load” output. Use to adjust sengs aer long
pressing the menu buon.
Long press at home screen to engage or disengage the “load” funcon.
WHAT THE HECK IS THE “LOAD” OUTPUT
FUNCTION?
The load funcon is typically used for lighng applicaons, hence the light bulb icon. It can commonly be
set to turn on a load output aer dusk (when the charge controller detects 8V or less, it assumes it’s night
me). The me aspect (24h, 1-15h, 0h) is the me the load output will remain engaged. Aer this me is
elapsed, the load output will be disengaged.
Important: The load voltage sengs and me sengs must be sased in order for the load output to
engage.
