Hey All,
I've got a MT50 controller hooked up to a Solar Epic Tracer 4215BN charge controller that is putting power into a 12V AGM.
I'm currently using the suggested settings for a Gel battery and making the assumption that these settings will work for my AGM. Below is a chart that I retyped from the users manual, please forgive any typos. I can't say I fully understand which each of these rows means and the manual doesn't define them well. If someone out there has a resource on this please pass it along.
One thing that gives me pause is the Low Voltage Disconnect Voltage line which is set to 11.1V. Based on my study of batteries so far if a 12V battery falls below 11.8V or so it dramatically reduces the life of the battery. Is this correct? If so should I change this to something higher than 11.1V?
Any other considerations when configuring this charge controller and battery?
Thanks
Rich
