Renogy Rover MPPT E1 error

Hi,

I have 300w of portable Renogy panels hooked up to a 30amp Renogy River charge controller connected to 4 Lifeline Agms.

Checked the manual and the party is battery over discharge error.

Victron shows shows me at 93%.

Anyone have this issue before?. Will call Renogy on Monday

Thanks,

Hi,

I was unable to get in touch with Renogy but I think I need to change the settings on the charge controller as I think they returned to default over the winter.

It will be Saturday before I can do it.

Have a fuse or breaker between the controller and batteries? I had a bad 40A breaker that kept tripping at 10-12A and I'd get that same error because it can't sense the batteries. How is the wiring between the batteries and the controller? That all in good condition and connected well?

Had a look at the wiring and it looks ok. I am on hold with Renogy right now and will report back shortly. I do have a fuse coming from the panels.

Renogy reckons it's the charge controller programing. I need to make sure it's set to 12 volt and sealed battery.

I have an old own control lee I can hook up of needs be.

As it's portable I could do the programming outside and it's raining.

The fuse from the panels is not the issue. The over discharge error is because the controller can't detect any voltage from the batteries.

If you disconnect the fuse from the panels (so controller can not output anything) and then hook a voltmeter to the controller output with the battery cables connected to them, do you show any voltage? If so, then the controller is probably the issue. If not, then there is an issue with the wiring.

Is your setup connecting direct the batteries or is there a battery disconnect in the path?

I will program the controller first and if it does not work will try my pwm one and check the connections to the batteries.

I do not have a disconnect between them.

Will report back when a couple of days.
