Hello.. I have a 60amp Morningstar MPPT solar controller. I’m thinking of going to Lithium batteries. My question is, does anyone know what the dip switch settings would be ? I’ve tried contacting the company, with no replies...thanks
 
Doesn't that one allow you to do custom?
Then it really becomes a question for the battery manufacturer not Morningstar. Are you assembling your own lifepo4 pack?
 
Thanks for the reply. I can’t get Battleborn because I’m in Canada, they won’t deliver, so I’m looking more at Lion. My biggest concern with the dip switch is to get this right, I’m looking at $1400.00 CDN per battery. At the moment I’m running with 4 - 6volt flooded deep cycle, but it’s not enough to run my rig and I need to add 2 more, but now I’m getting into a weight issue
 
I have the 6o amp mppt and I am about to rehook things up in the next couple days. I will look at my settings. I have a DIY lifepo4 pack. The morningstar is very flexible so I would look at the recommendations for whatever battery you get. The drop in batteries often rely on their internal BMS so sometimes there recommendations are different. If I recall correttly I take my charge up to 13.8 or 14 and then go to float at a lower level. When I get my stuff out I will check for you. There is no need for the for the equalization etc like on the lead acids. You make it simpler. The online owners manual for the mppt does a good job of explaining the options.

How did it go ??
 
I do not have the final hookup yet. I have a temp 12 volt hookup and it is working but I am having problems. I am using the gel setting which is what I have used in the past. It is 14 V bulk and absorb and then 13.7 float. The problem that I have is that the battery pack voltage differs quite a bit from the voltage the battery sense in the Morningstar shows. So the morningstar shows the pack has hit 14.V but when I use a multimeter at the pack it is actually at 13.3. I need to put in the permanent wiring and recheck everything. I don't recall this ever being a problem before but this 6 year old controller has seen some hard times. It shows no faults but I have never seen this voltage variation before. When I get my wiring finished I am going to use customized settings. http://support.morningstarcorp.com/.../07/TSMPPT-IOM-MS-000946_304560A_v6.9_WEB.pdf
 
Is this what you are looking for? The voltage would be set to custom with dipswitches

I also have Tristar charge controllers and want to move to lithium..
Apart from getting the settings correct, I'm more concerned with how to protecting the charge controller from any disconnect the BMS would trigger.
What are you planning to do?
 
I'm a little bafuddled . . . why aren't you folks just calling up MorningStar and asking them directly? They do answer their phones, they ARE very knowledgeable, they ARE engineers, every time I've called they were very friendly and spoke EN natively.

They've been happy to answer questions or provide product information via email.

Just my .02c > USD currency though.

Among other things, Morningstar runs a webinar on its controllers once a month, during which it addresses technical questions that people ask. I wrote about the April webinar in this post: Morningstar Controller Webinars and Resources.

As I understand it, Morningstar has resources on pairing its gear, in some cases, with batteries that are made by specific companies.

Last week, I sent Morningstar a question about its SureSine inverter and grounding. I do think that it's helpful to be specific about questions and to be concise about context. I don't know whether I succeeded, but the text of my query to Morningstar is in this post: https://diysolarforum.com/threads/grounding-basics-not-basic-enough-for-me.20401/post-257536

I received a helpful, clear, common sense response within a couple of hours of asking the question. That followed a rabbit hole discussion in the thread that the post is from that went on for two pages :)

I am now using the ElectroDacus system. Last summer I ran the the MorningStar using the custom settings through the MSView software same as time2roll did. It now serves as a backup system for the FLA-LFP hybrid bank.
 
I would use the GEL setting of OFF-OFF-OFF.

MANUAL P22

Start at the beginning

#1 OFF
#2-3. Set the voltage to your actual battery. OFF-ON is 12 volts
#4-5-6 GELL works and keeps equalization off. For lower float use Flooded setting 5 with 14.6 and 13.5 Bulk and Float. ON-OFF-OFF. If you select Flooded be certain you set #7 to Manual equalization. With switch set to OFF
#7 Automatic equalization should be set to OFF
#8 will be off unless you will be using the ethernet port for programming.

There is no lithium setting per se
