Question 1

is 240 watts the maximum? I have a 300 watt 40v solar panel i want to use to supply daylight 12v to a fan and security camera to. will work? losses?

Accepted Answer

Yes, 240 Watts is the maximum but something to keep in mind when dealing with power ratings (Watts). The key to your power requirements is the load. In your case this is the power requirements of the fan and camera. As long as the power requirements of these two devices is less than 240 Watts then you will be OK. A power source, which in your case is the solar panel, will only deliver the amount of power being drawn by your fan and camera. The rating on your solar panel is telling you that it can deliver Up To 300 Watts. Yes, 300 Watts exceeds the capabilities of the Voltage Reducer (240 Watts) but as long as your fan and camera never draw that much power your solar panel will never deliver it.

Question 2

Will this work on an EZ Go to run the headlights and tail lights?

Accepted Answer

Yes, should work with 48 volt input to get 12 volt output - but is limited to 10 amps output.   To much load will require more amps.

Question 3

Where can i find a wiring diagram to install? There were no directions included in the package. I have 4 colored wires and not sure how to install

Accepted Answer

The red and black wires are the 48 volt input connections from the batteries. The remaining yellow and brown (I think) are the 12 volt 10 amp output connections to wire your accessories. Be sure to mount this somewhere that heat is not a factor as unit gets hot when stepping down the current.

Question 4

Why won't this work to convert a car accessory 12v to a pc battery charger 19V?

Accepted Answer

I attach 2 48 volt electric bicycle batteries  with not heat issues. No experience with Auto or Equipment application.
