Thank you for the reply, the light is a 10Watt DC light and is used as a night light with a on period of about 10 Hours. I am not sure if the COB can handle 24 volts and not burn up due to the voltage. I can test this later as I build this units and or replare them all of the time. Another...

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...

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.

Thank You everyone for your input!

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!

Greetings, I will try and keep this short, I have an existing solar system running at 12V's, a 200AH LiFePo4 battery, a100Amp BMS and a Tracer Solar Charge controller (SCC) ! All is working well. The issue is we are having many, many days of heavy clouds and rain and my battery is loosing its...

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...

The unit I have is a Tracer-4215 BN-

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...

Hello Mike, thank you for the detailed description regarding the setting up of the MT50 controller. The information that you provided is very helpful in understanding the functions of this controller. However my current issue is in getting the MT50 that I purchased to take the voltage changes...

Greetings All, I am having an issue with MT50 controller connected to my Tracer-4215 BN, the issue is getting some of the values to work or rather be set inside the controller. I have been able to set the time and date as well as the optional light feature. In addition I have been able to set...

Thank you Frank for all of your assistance. I had sent to you information on the private forum chat we have had but you may not have viewed it. If you see this, please view what I sent you. It seems that no one is interested in assisting me so I guess I will just have to go it alone.

Thank you everyone or all of your efforts. Please let me clarify some issues raised, regarding the use of studs versus bolts they are all Stainless steel bolts and for ease I continued to use them even through I had cut longer Stainless steel studs to be attached to the terminals at a point when...

Here is an image with both chargers charging the battery! Please not I was charging at 13.4 volts but as the battery got full the amperage reduced I ten increased the voltage to 13.6 volts to supply extra voltage. There was no BMS on the unit and I manually shut down the power supplies as soon...

Things have gone from bad to really bad. I set the cells up in a series configuration and connected one of my desktop chargers cables the + and - terminals on the batter then plugged them into my Brand New 3010P charger and boom. The unit was not plugged in to AC voltage and the unit was not on...

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...

It is with a great amount of sadness and frustration that I have to report about a shipping failure by AliExpress and one of their sellers. The seller in question is LiFePO4 battery 18650 battery Store . I ordered 4- Prismatic 3.2V 200AH 3C LiFePO4 Battery cells, the seller said that they would...

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...

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

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...

In my comments above I provided the name on the cable. The printing on the cable says the following; DAIDO Welding Cable 35 Sq. MM.

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

Yes I went to every store in the area with the cable in hand and they either had none or lugs way, way to big. As a side note I actually ordered in the past some lugs for this cable using the cable size as a indicator. Obviously the lugs are way to large for use with the cable (The cable just...

One last point it appears that the cable MIGHT be a #4 AWG cable even though nothing says that on the cable and the sellers of this cable know less than me!

The cable has a double insulation material with the outside jacket being orange in color and the thicker inside insulator being black. Other than what I have said and shown by the image there are no other markings. The source of this cable is from a hardware store that sells items to the locals...

Thank you all for the quick reply! I have the cable in my hand as I type this the writing on the cable says DAIDO Welding Cable 35 Sq. MM. I stripped the insulation off of the cable and used a micrometer to measure the copper center of the cable. Of course when the insulation is removed the...

I am having a real issue in getting a copper lug to fit the 35mm welding cable I am using for my LiFePo4 battery. When I remove the insulation from the wire the copper core is approx. 5mm to 6mm in diameter. I inadvertently purchased what I thought where the right lugs but they are way to large...

Some good ideas here! Thank You!

Thank You for the point by point discussion it is helpful in assisting me to make the right decisions.

I am waiting for the arrival of my 4- 200Ah LiFePo4 Cells they are new grade A cell direct from a manufacture. I have been working on setting up a back board with all of the connection and testing points on it and am waiting for the cells to complete the installation. In preparation I have a...

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...

Greetings All; Now that I have my base solar system upgrade out of the way it is time to look at my panels. My solar controller is a EPEver Tracer 4215BN this is a 40 Amp controller with the usual add-ons. At present I have 2-55 Watt panels wired in Parallel to provide me 110 Watts at 18.0 Volts...

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

I hope that I can get clarification on why I need a shunt on my system? I understand the basic functions of a shunt and in my mind that is to work with a Amp meter to determine the amperage/current being used. My system has 4-200Ah cells placed together to form a 12Volt battery. On the positive...
