High voltage device.
Installation should be 

performed by an electrician.

This device will produce heat.  
Mount device away from other 

items.

Electronic Equipment. 
Do not put in landfill.

A wire cutter is needed for 

cutting and stripping prior 

wires to connect.

A multi-meter is needed for 

testing equipment and verifying 

polarity of cables.

Anti-static gloves are 
recommended to prevent 
controller damage caused by 
static electricity.

Electrical tape is recommended 

to safely insulate spliced or bare 

wires.

A common size screwdriver is 
needed to attach wires to the 
controller.

· 

 It is very important to review this manual thoroughly before attempting installation.

· 

 Beware of any nearby electrical equipment that may interfere with installing this 

device. And please don’t plug in any AC source to this DC-DC product, or it may cause 
a fire or burn to the device.  

· 

 Connecting wires to this device can generate sparks, please wear proper insulation 

gear while installing this device.

· 

 To avoid damage to the battery or controller, use proper fuses in wiring. Please do 

not hesitate to contact the professions if you need help with fuse sizing.

· 

 This device is common negative designed, please wiring negative grounded if 

grounding job is required.

· 

 Please don’t keep the battery side open for long time, while the PV input keeps 

plugging in, or it may cause a screen failure in this device. 

· 

 Always keep children away from this device.

· 

 Be certain to use the correct gauge of wire, see below for a table of recommended 

wire size for various current loads.

· 

 Solar panels can generate high voltages and currents, make sure your solar panels 

are completely covered from sunlight during installation. It is recommended that 
installation be performed by a qualified electrician.
