EPSolar MT50 problem!!

[TUCQUALA]

My less-than-a-year old EPSolar MT50 remote readout is showing "connecting" on the screen and will not do anything through the buttons. The green connect light is not on. When disconnecting and reconnecting the RJ45 at the controller, the MT50 will light up the face, but only shows "connecting".

Since supplier is in our 51st state of China, I thought I would ask on here while awaiting a reply from them.

Anyone seen this or heard of??? Nothing in manuals aboot this problem.

Thanks for the ideas!! To those who pointed toward the controller, it is working fine. It is the MT50 remote readout that is having a problem. My fault for not defining in my orig post that the controller is still working fine.

Have "rebooted" once, will try again and recheck. Seller will replace for 1/2 price shipped!! I guess not bad, considering how much it would cost to return to China and wait for how long!!!

YES I have the grape solar 40, it's not mppt
But I love the blue tooth connection to my tablet and phone for setup and monitoring
The app has a little bug and reports the wrong kwhr..total
But the amps reading, voltage etc,, are all good
Grape Solar is working on the app, said they would email me a link for download when the new one is ready

disconnect solar
disconnect battery
wait 30 minutes
reconnect battery
reconnect solar

Likely there are no user serviceable parts. If so look for the Grape 40 amp controller. Mr Wizard is using one IIRC.

Try rebooting it by disconnecting the solar panels and battery then reconnect.

The only thing I can suggest is to check and clean all the connectors. That is standard advice for any electronic problem like that. Look at the connecting cable too and make sure it isn't damaged. RJ45 connectors are notorious for going bad, replace the cable if nothing else works.
