Having an issue with this unit no lighting or info on display. Promarnier invertor is working and I checked the rear plug to the unit. Does this also mean there is no solar charge? Is there a fuse somewhere?

Thanks gerry
 
I had a similar problem on my R27. Turns out the small temp sensor on the Morningstar charge controller had corroded into dust and disabled the charge controller. I was getting no response from the remote and no solar charge from the panel. Ordered and replaced the charge controller in the battery compartment and "voila" instant response from the remote meter and charge from the panel now back. You might look at the MPPT type of controller versus the PWM controller that is the Morningstar replacement. The MPPT type controller is reported to give a higher level of charging to the battery. I'm researching and considering moving to that type of controller once the new Morningstar controller gets a little older.
 
There is a possibility the the remote temperature sensor is giving you the problem. Usually there isn't one! However if the connector for the sensor gets wet it causes continuity and then thinks you have one. When it dries out then it thinks it lost the sensor and you get a fault. Try this: First remove the fuses between the batteries and the controller. Then remove the feed wire Positive from the solar panel to the controller. Be careful, this wire is live, do not let it touch anything. Wait one minute. reinstall the positive lead from the solar panel to the controller. Now reinstall the fuses between the controller and the batteries. That will have reset everything and you should be back in business. If that was your issue, just jump out the connections for the remote sensor with a wire and this problem should not happen again.
If this does not correct your problem, make sure all connections are good at the solar panel at the controller and at the batteries. After that, you should call Morningstar. You probably have a bad controller.
