Thanks everyone for your input. This has turned out to be a very active discussion.

OK, I seem to have found the problem with changing some values on the MT50 that I have. There is some sort of issue relating to the MT50 it seems as though the OK button does not work well. Even using the password (000000) gets rejected sometime and then at other time it works sometime on the...

Thank you you explained this very well!

The potential loss of Amperage in adding a new 110 Amp panel is a concern. The price given by the supplier that I have used in the past is now nearly equal to a new 345Watt panel. With this in mind I will be better off buying a new 345 watt panel and pulling the 2- 55Watt panels out of the...

Due to a failure on Ali Express my order for 4-New 200Ah cells where lost. I had been waiting for these cells for 2-months, as a result I ordered from a seller in Bangkok 4- 200Ah CALB clone cells. The reason for selecting these cells was the very low resistance. The cells arrived and I tested...

Thank you again for your input!

First off thank you HRTKD you fully understood what I was saying and you answered my question so well that even I understand how the connections take place. The image with the bus bars simplifies everything at least for me, thank you again!

Greetings All, well I started my day off with a bang no an explosion type but rather a purchasing explosion. I ordered a set of 4- 202Ah deep cell LifePo4 cells and in addition I ordered a Trace 4215BN SOC. I went this route due to the high recommendations put on the products by Will Prowse. I...

Thank you as well GXMnow, for your detailed description on the functining of a BMS. This parrallels my thoghts completely and shows that I am now on the right trck. Thank you again!

OK found more information out on these batteries. They are a Class B battery and are used in some cases with 90%+ capacity left in the batteries. With all of the misinformation going on in this technology and sellers who care little about buyers it can be a real crap shoot!

Thank you Mr. Martin for you excellent assistance.

Thank You everyone for your input!

You are right, dealing with Chinese sources or even local suppliers selling these types of products is a crap shoot, especially when trying to get a price that fits in the budget. Here is another example of this marketing: SINOPOLY 100 ah 12v +BMS lithium ion Lifepo4 GRADE A UPS Battery 100ah...

Thank you JMH1783, your explanation was very clear and helps a lot. Thank you again!

Thank you HRTKD, I understand having quality items is often the best solution the key is making them fit into my budget. My solar array is more of a learning environment than a production system. Thank you again!

I tackled my system again and managed to change a few values. I have given below the values that exsist on my MT50 as of this writting along with the descriptions. 16.0V Over voltage Disconnect (Para, Error) 15.0 Charge Limit (Para, Error) 13.2V Over voltage Reconnect (Para, Error) 13.4V...

Here is an end view of the copper conductor in the cable.

I have a a basic 12 volt lithium Ion system and it is working well. My thinking now to double up on the cells and move to a 24Volt environment. The issue that I am unsure of is whether by doing this will the Tracer-4215 BN controller change the accessories output to 24 volts as well. What I...

Sorry for the confusion regarding the desktop power supply what I was referring to is a DC 30 Volt 10 Amp Programmable power supply. See image below!

I ended up purchasing a Tracer 4215-BN. I hope that this helps??

I am looking at buying an EPEVER SCC and found this style that seems to be available here now. Does anyone have experience with this design and its functionality? I have been considering the standard style of unit but this one seems to come in cheaper.

Confused about what these cells can be used for? The description reads ( SINOPOLY 100 ah 12v +BMS lithium ion Lifepo4 GRADE A UPS Battery 100ah high capacity Sound System). Can they be used for a solar array?

OK, I have finished with my planning and thinking about what voltage I want to get to in the future. I have settled on 24 Volts DC from 8 Lithium Ion Batteries. I have two options going forward: #1 Is to purchase 4- 100 Watt cells and do a parallel connection then upgrade to another identical...

I have an existing Solar System and it has been working well for the past 1 1/2 years. It is a very basic system and was intended to be a test and light useage system in my small shop. The system contains 2-55Watt solar panels in parallel running to a cheap PWM controller then to 130 Amp lead...

I am confused some what about the size and type of wire I should be using for my small solar set up. I have a single 340 Watt solar panel (8.9Amps/38.2 volts). These are of course maximum output under ideal conditions. The controller I have is Tracer-4215 BN, and is connected to a 200Ah 12 volt...

OK thanks all! From what I can make of this compression is more suitable for mobile applications. For solar having the cells together held by double sided tape and bus bars should be fine. The other issue is an enclosure for the cells/battery; should there be ventalation holes in the storeage...

I ordered today a Tracer 4215bn 40 Amp SOC for my new solar system and will be ordering a MT50 meter. I live near the equator but not on the coast so I get a lot of sunshine. Thank you for your reply!

I have decided to hold off on the Wifi connection until after my basic setup is complete. Thank you for you reply!

When looking at the cable you can see that the insulation is very, very thick. In my mind the OD of the cable could yield a 35mm^2 cable. Like most everything sold here in Thailand it comes from China and as well all know many companies just do not stay with standards but rather bend results to...

Greetings, I am currently using a MT50 with my Tracer-4215 BN. I am thinking about changing the connection method to either WiFi or Blue Tooth. I am sure some users have experimented with both add-ons, and I would like to hear the plusses and minus for one over the other? Thank you in advance.
