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.

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...

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...

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 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...

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...

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...

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...

Greetings every one. As mentioned in the title I am moving from a basic lead acid solution with a cheap PWM controller to a EPEVER Tracer 4215BN and a set of 4- 12V 200Ah cells. I received the 4215BN yesterday along with the MT-50 I ordered and this morning I wired the controller to my existing...

I am trying to wrap my mind around this topic and hope by sharing my thoughts it will confirm or provide for something I have missed. Using a cheap BMS versus an expensive one has obviously quality differences but in addition the cheaper BMS have preset upper and lower voltage cut offs and the...

I have watched many video on assembly of cell packs and some stress using some form of compression to help the batteries to maintain there wall rigidity. Other video's show leaving and air gaps between the cells to help with heat dissipation. My thinking is that the compression might be used...

I have a small system now but am upgrading it and want to future proof some aspects of it and one of those is the solar controller. I have ordered a Tracer 4215BN device even though a 20Amp Solar charger would have been all that I need presently. With things coming now I am trying to have the...

Well after a month or so of working on many difference possible solutions and especially thanks to people on this site I have now a hardware configuration that I will try and follow. I plan on adding a Epever 2210An SOC with a 20Amp rating. The next thing I would like assistance on, is in...

To future proof an 12 volt system using 4 Lithium Ion cells can one purchase a Daly S8 BMS and connect only 4 of the leads to the positive posts of the cells? Just trying to understand the basis of balancing cells.

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...

In my part of the world there are sellers selling 100AH and 200 AH batteries and the listing says the following. ( CALB lithium ion Lifepo4 12v GRADE A 200ah 4S 4 CELL UPS Battery ) I want to change over to Lithium I have a couple of images below: Ion batteries in my solar system will these...

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.

I am now planning a complete redo of my small solar system, at present I have 2- 55W Sun Power Mono Crystaline panels connected in Parallel running to a PWM controller then to a 12 volt battery. My thinking is if possible for me to add a 110 Watt Mono Crystalline panel to the existing 2-55 Watt...

I am trying to build a basic sort of system with expansion capabilities, cash is on the tight side but have found this No Name charger that I hope someone might have some experience with. Because the add that I am looking at does not have a name associated with it I am including an image of the...

I am wanting to upgrade my system from a basic lead acid to Lifepo4 and 100ah cells should be fine. Cost is an issue and I have found these cells on sale here. Does any one have experience with these cells and what a novice like me should be aware of. Thank you in advance.

I am considering upgrading my solar system from a lead acid battery system using 2-55 Amp panels connected in parallel with a cheap but good working PWM controller. This system was set up about 2-years ago as a testing environment in my small workshop. At present the system has a 12 volt DC...

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...
