After just a few months I keep getting an Error Code E10 on my Wanderer 10 Amp, with no solar panels attached to it. It is supposes to know whether it has 12 volt or a 24 volts battery bank. As it boots up it will keep showing 24 volts even the input is only 12 volts. It shows a minus voltage on the display since it thinks it should be a 24 volt input.
How can I do a system reset or what else can I do to make this controller work?

What are you doing with the wanderer? Are you using it as a volt meter?

What are you doing with the wanderer? Are you using it as a volt meter? I'm using it as a charge controller as it was designed. The display will give you a readout of the solar panel voltage and also what the battery bank's voltage is. |

But you said... { with no solar panels attached to it. } So if you don't have panels attached what are you using it for....... I understand how they work........... |

I'm simply saying that even with the panel detached with no input from the panels the voltage the controller thinks its hooked up to 24volt bank. Actually same bad readings with the panels attached. |

djhphoto, in Li battery type the 12/24 is selectable. I'd try that, set to 12v then change battery type to what ya want.
Other than disconnecting and waiting some time and reconnecting! Seems that is not working for ya!
warranty return.

Ok now I'm understanding........ Call Renogy and ask them if you should return it...... Don't send an email or leave a message, wait until you can talk to a person for an answer........... |

The controller might be auto detecting. What voltage is your battery bank that you're trying to connect to? |

You should:
(1) Disconnect everything.
(2) Make sure that all wires are connected to the correct input (PV / Batt) and secure
(3) Measure the disconnected battery (ies) with a voltmeter to verify correct voltage. Li-Fe might appear "dead" if the BMS has detected over discharge.
(4) Connect the batteries to the CC first. Wait until the CC comes alive and settles down.
(5) Now connect the PV, so that you have a source of power to charge the batteries
(6) Wait more time for CC to correctly detect the battery voltage. Renogy CC have a "wake up" feature for over discharged Li-Fe. But it can't do that if there is no input power to charge the batteries with!

^^^^^^ I agree.......^^^^^^^ I think he's trying to figure something out without everything attached that is needed to do so............

What voltage is your battery bank that you're trying to connect to? I believe it is autodetecting. The only option I have. I am connecting to a 12 volt battery source. Worked just fine for a few months...... |
