12 Volt System. Maximum Charge

[Grumpy Grampa]

I have a 2017 Miramar 37.1. With 4-each 6-volt batteries, 12 volt system.. I have the coach in storage with a 100 watt, solar panel and 12/24 Renogy controller.
What is the maximum battery volts . I checked and got a 14.2 reading , does this seam right?

Best thing to do is download the product data sheet for your batteries

Then you can program the charger correctly

Bulk
Adsorption
Float/finish

All have different recommendations for volts based on your specific battery

14.1 is perfect.

12.8 is the maximum "resting" voltage.

14.6 is the maximum charging voltage.

If the batteries are fully charged than 14.1 VDC will cause excess gassing.

13.1 to 13.3 is the maintenance voltage.

My charge controller indicates 13.6 the majority of the time. However, it occasionally will show 14.1... which is bulk charge, which helps with minimizing sulfation. These settings are available in my solar charge controller settings.

Thank you. Great information on a newbe solar guy.
