Ok well you can always take then up close to the top then use your desktop charger for the last part. When connecting things like your active balancer and BMS, connect all your sensor leads before connecting to the device. On my caravan I go up to 90 - 95% and have it set for down to 10%. I...

Great to hear :)

@ghostwriter66 did a great post on cell quality so maybe she could shed more light on the quality given the changes by EVE and CATL. https://diysolarforum.com/threads/how-to-tell-the-difference-between-grade-a-and-grade-b-cells.28114/

No matter whether you have a 50Ah or 100Ah battery there is no difference in the system. The crucial things are that if you are connecting more than two solar panels in parallel then you should fuse the panels. The others are providing a fuse between your battery and inverter, and battery and...

Ok I have a 40amp EPEver Triron and 560AH of Lithium batteries. What do you want to know exactly. Firstly you need to connect the solar controller to the batteries. Change the settings on the controller to the battery type and then connect your solar panels. Always connect the controller to...

Whats the issue?

Hi again, I see you posted your questions here. Your solar controller uses less than 12mA. Firstly, 100W flexible panels on the roof will not provide you with great power being in the UK. It would be better if you had some portable panels which you could angle to the sun to supplement the...

Hi again Chadd. That reply from the Amazon seller is so wrong. I have found a EPEver seller and no EBay is not always there cheapest option. 30A Epever Triron The seller has a physical address and phone number and if you read the description you will find it is meets all the parameters...

Yes the cell difference is excessive Yes that is excessive. It states that the cells are balancing so at what level of imbalance do you have your BMS configured to start balancing.

Ok John, you said you have a Daly 4S 12 volt, do you have two of these now or are you using a different BMS. we need to start back at the beginning. I now understand you want a 12 volt system so as i said previously you need another 4S 12 volt Daly BMS. I currently have one bank of cells and...

Sry to hear of your predicament and hope that you are ok. Generally 12 hours for electric components to dry out and as you have been able to open it up and left if for 4 days then it should all be dry. I’m no expert but if I was in your situation I would turn it on and give it a try. What I...

In the end I didn’t change anything. The Bluetooth will disconnect when you move some distance from the BMS but that is normal and you need to reconnect. Are you saying though that the BMS turned off? Unfortunately, I am unable to tell you my settings as my caravan is 800kms (500 miles) away...

All good it wasn‘t a duplicate just an introduction in Newcomers :)

I have your sun for a few months but you can have it back next year :cool:

Ok not sure what you mean. Can you clarify as I think you are talking about your shunt. What are your bulk, absorption and float settings i thought Victron had a LifePO4 setting so that you didn’t have to change anything. I will look at the manual tomorrow for you to check. In relation to no...

The sensor wires are the small wires that you connect to each cell. Do you have photos of your setup? To disconnect them just unplug the connector.

Hi I’m in Australia too, well in Mykonos at the moment :cool:. To be honest unless you are building your own batteries the cost is not worth the time it takes to recoup your investment. You should of installed the largest system possible and then switched do doing things like pool pump...

Ok I just took a look and they are saying shipping to Australia $93 and delivery in 4-6 days. What a load of rubbish as they have to come by ship. Stay well clear is my opinion you may pay extra but be assured of a real product. If you paid by Paypal then the delivery date may extend beyond...

Ok, lets take it step by step. You have connected the BMS back up and it is still on. Have you checked the voltage through the BMS? Can you post a pic of all your cell voltages also. The bluetooth will always disconnect when it loses signal. That isn’t an issue as you just reconnect through...

Bought from Amy at Shenzhen Luyuan. Paid a bit more but these are supposedly their top cells as opposed to the commodity cells. As so bought my BMS which was the same price as the Daly website but only $12 extra shipping.

If you are going to use the inverter for the fridge only then you are able to use a smaller one. Not sure what the current draw on this one is and I couldn’t see it on the 1000 watt one either. I was anticipating a large current draw on my 3000/6000 but after leaving it on for a couple of...

Who are you buying from? I have had two shipments of 4 cells plus BMS and there were no extra charge for GST or customs. Goods under $1000 are no longer GST free. Goods under $1000 and the seller collects and pays the GST, over $1000 and you pay...

When stating 6 AWG they are looking at the controller maximum specifications and not what amps the panels will be producing. 10 AWG is fine From your panels to controller. Run 6 AWG from your controller to your batteries.. Sry in Dubai at the moment on my way to sunny Mykonos.

Hi John, happy to helip but just got back from a 800km drive so will follow up with a post in my morning. Tim

Great I see HRTKD has been helping you. I think your fridge will have a cycle of less than 50% but you can always test it out if you have a watt meter. Victron are top of the range and pricey. Although I have some Victron things I have an EPEver solar controller and Giandel inverter. Choose...

No you are not able to plug shore power directly into your inverter. I’m not sure what that cable is that you have posted is it to connect from a shore power source to a trailer. In Australia we generally use 10A for domestic services with a dedicated circuit say to a cook top with a 15A...

Hi Tim, not sure what sizing chart you mean but links at bottom of page take you back to the top of page. Also says shipping by Air Express lol. Then it says on one item ‘4pcs EVE 3.2V 280Ah Prismatic LiFePO4 cells with Free Ship by Sea 48-60 Days to door Grade A in same matched batch. New and...

What differential cell voltage have you set the BMS to start balancing as it shows your is turned off. I set mine to .02v.

Read about a case where someone working on a car battery had a spanner in his hand whilst doing up a terminal connection. He was wearing a ring which touched the other terminal and provided the circuit through the scanner to the other terminal. If I recall he lost at least one finger.

I did say that the SOC should be accurate but in actual fact it isn’t really. Once the battery has settled from charging or discharging then you will get a more accurate reading. Don’t be too worried about SOC as your BMS will handle everything. An example of this is yesterday I was testing...

Hi Batty I think @wattmatters will be able to help you regarding the regulations. I can’t understand why people install Tesla Powerwalls when you can just install the largest solar system possible and sell back to the grid to offset the cost of any electricity you use from the grid. It would...

Ok Cell 1 is a little low but hopefully things will balance out when you connect up. Just see how it goes now and if you still have issues then I would do a factory reset.

That looks like your inverter is reading directly off your panels, which it shouldn’t do, or your battery set up is wrong But with just two sets of 4 cells it shouldn’t be. Disconnect everything and work through the process of connecting it all back up in stages. Start by disconnecting...

Yeah my bad I didnt look at the panels current. I’m sitting at an airport when I should be fast asleep in bed.

As Rmaddy said and remember to connect your solar controller to the battery’s first then connect your solar panels.

Lol didn‘t see that. Danger! Danger! Danger!

I just looked at the reviews. He needs to send it back.

Anderson connectors are more durable than MC4 connectors and they are quiet easy to install on a cable once you get to know how. I solder mine.

Hi Chadd, I just had a look at his web site and it sends out big warnings to me. I wont go into detail just yet but what is a guy doing selling batteries in a car boot sale 18 miles from his so called warehouse. He claims to have been off grid for 20 years and bringing the price down on...

Welcome Mary. Plenty of help to be had on here from posters with some fantastic knowledge. Good luck with your system :)

X2 for Epever. Michael has given you some good advice.

You might want to look at this video.

Please let us know if you resolve the issue.

Yes, no problem in attaching two controllers to the same battery. Just remember to connect the controller first and then panels second as most require connection in that order to determine battery voltage.

Have you tried disconnecting the balance leads, removing the Bluetooth dongle and the temperature sensor it that is removable. Then reconnect it all back up as per the instructions. I thought I had destroyed one of mine at one stage but going through the the disconnection and reconnection...

Hi John, What you have is 8 cells at 100Ah each so if you put 4 of these in series you then get 100Ah @ 12.8volts. If you do the same with the other 4 cells then connect them in parallel to the first pack you get 200Ah @ 12.8 volts. As per MisterSandel‘s post if you put the 8 in series you...

I have a 250A version and i have the same issue in that it is showing negative amps when charging. I also had other issues in that the temperature wasn’t being displayed and it was displaying another message about temperature setting. I hit the reset button and the temperature issues were...

Ok lets go back to the start. who are you buying your ‘A grade’ cells from. There are different grades of ‘A’ grade cells and Ghostwriter has written an excellent post on this. https://diysolarforum.com/threads/how-to-tell-the-difference-between-grade-a-and-grade-b-cells.28114/ I recommend...

Why don’t you split them into two packs of 8 it may cost you a little more but will reduce costs of port collection.
