Hi I bought a Rover 20 amp controller recently. I have a 150w panel and 200 AH battery. I would like to run some LEDs off the load terminals so I can have the lights on the built in timer. My problem is that I can't wire in a DC-DC step down voltage convertor to protect the LEDs because as soon as I connect the convertor wires, the Rover throws a E4 error. I've tried two convertors, neither work on the Rover but have no problems on hooked up to a cheap Chinese charge controller I use on another smaller battery. The convertor specs are:
DC to DC Step Down Voltage Converter Module
- Input voltage: 6-28V DC
- Output voltage: 3-15V DC
- Max output current: 1.5A
Does any one know how to turn off this Short Circuit "feature" or have any other ideas how to limit the load voltage to 12v so it plays nice with my LEDs?
thanks
Andrew

(1) do you have other 12Vdc loads (not DC-DC down-converter) connected to this configuration that are working correctly and no E4 error? (2) What happens to the Rover when the E4 error is displayed, does it go to zero volts output? (3) does the E4 error occur with just eh DC-DC down-converter connected, with out any loads connected to the low voltage side? is it possible the Rover is defective? |

That's there for a reason... Does your CC work without a load??? What are you hooking the inverter to?? |
