Thank you for posting this video as I have never seen it. It just goes to show what a great character Will is. Like myself he could of put blame on his parents, but no, inspite of their shortcomings he still showed he loved them. Thank you for everything Will and I wish you all the best for...

If you are generating enough heat at the lug connection to melt solder (between 400°F / 200°C and 700°F / 370°C) then I would suggest that you have a very major problem.

And as above (y) for Amy

Booce stand proud and thank you for caring. It is sad that the so called leaders of a country together with the so called entitled do not care and have no empathy. Quality clothing and bedding will go a long way to helping people. As long as they have food the body will generate heat and the...

In Australia even if you sign a contract we have a cooling off period where both parties are able to withdraw. I hope your friend has this option because I do not know what prices are like over there but last December it cost me AU$7,490 for a 9.9kW grid tied system or US$5,095. That was for...

My electricity bills generally were between US$462 and US$510 for a quarter. My first bill after the system was installed was US$39 and received my second one yesterday for US$42. Electricity prices are taking a jump here and I reckon payback time will eventually be less than four years.

I did correct it and it didn't save the first time :(. Anyway I think you will find that John is building a 12v system and if he returns we can hopefully help him out.:)

I agree with you and mfg stated that there was only a $50 difference in price. I have a 3000/6000w inverter but my two 280Ah batteries each have a 250a BMS. This was because I built one and then built another later and wanted to keep the same BMS. Whilst I have a 3000w inverter I have never...

On the top one the wire stands are still poking through so I would suggest you have trimmed the insulation back a little far. Put some heat shrink on them and it makes it nice and neat but otherwise it doesn't really matter as long as the crimp is secure

Just my 2 cents worth. There is quality, acceptable quality and runbbish… rather than messing about with them buy some acceptable quality connectors and let that be the end of it for a good few years or pay top price for a few more years beyond that. You could try some self fusing silicone...

No idea about the GoWise but I have a Giandel and had worked flawlessly for the past 3 years. Will has also done a video on inverters and said good things about the Giandel. The only thing I would say is just check that the cables to the battery are adequate for the current and install the...

He is Welsh! Some are like that :ROFLMAO:

He has released another video on it today. :) He funny because he sort bumbles along as though he doesn’t know too much then u realise just how intelligent he is when he gets into his serious technical moments.

Definitely no reason to apologise. You required answers to questions and ppl here are kind enough to provide the knowledge

Let’s not get into things like Roots, Chains, Tons and Tonnes because it doesn't really matter what we use as long as we make it plain to everyone else. We are all smart people aren’t we :cool: and have a our friend Google to help us convert if need be.

Buy yourself a bench power supply, put your cells in parrallel, connect it up and wait :). And I mean wait! You will think it isn’t working. You will want to turn knobs. You will want to play with wires but nooooooo! Don’t touch a thing, just wait! Then the magic happens :ROFLMAO:.

I paid it outright.

Ok, Amy is fantastic and you will get quality cells. When I purchased mine I am assuming that the GST was included in the shipping costs as there were no other costs involved after the purchase costs. I would just check with Amy that that the shipping costs are from door to door excluding GST...

Yes it was and SmoothJoey is usually on the ball in picking up things. My apologies Joey but I couldn’t resist :). Hope you have had your coffee this morning.☕ Whilst I’m here rmaddy I have to say, I read many of the threads just out on interest and think it is absolutely fantastic how people...

Sry but I’m not that rude ;) , more than happy to share the details which I had already posted. It cost me AU$7,490 for a 9.9kW grid tied system or US$5,095. That was for REC panels and and 8.2kW Fronius inverter.

A Ok, charge your battery up to full charge. Go to the bottom right of the screen and click Parameter Settings. Then click cell characteristics. Then scroll down to SOC Set. Enter 100% and click set and it will ask your for a password which is 1, 2,3,4,5,6. You have then correctly set the...

It is grid tied but yes I have an option for a battery bank but to be honest it isn’t worth it. I use very little from the grid and the largest cost on my bill is the daily connection charge of AU$1.04 per day. The buyback rate is only AU 7.6 cents but it is enough to keep my bill down...

Ok you are building exactly what I have built two 280Ah batteries. You need a 4S BMS for each bank of cells. The size of the BMS will depend on your current draw and being in the UK and I being an ex pat probably the largest appliance you will use is a 2400W. So divide by 12v gives you...

Just curious, did you raise the voltage in steps and if so what voltage did you start charging at? I have just collected my RV after 4 months and both my two 208Ah batteries have discharged. One to 10.8v and the other 9.8v with plenty of cell divination and the lowest cell down to 2.344v. I...

No a problem John as we were all at that stage at one time. To reply to an individual post just click reply at the bottom right of the post. Did you mange to work out what you need from our mumble jumble? :ROFLMAO:

And you aren't the only one in this world that has missed such a simple thing. Welcome to the DUH! Club ?. Ok glad you got it sorted.

Hi Taffy, The fuse for the inverter is to protect the inverter. You also need to fuse the wiring from the battery to the inverter. To protect the wiring from meting and causing a fire. For a start what voltage system do you have, what size wattage of the inverter and what is the wattage of...

I have the exact same set up as yours except I have a 250a Daly BMS on each battery. The only reason that I have 250a is that I built one battery then built another. A 200a BMS on each battery will provide you with ample headroom and if you look at @FilterGuy post then you can see you could...

Hi Bilpohm I’m just up the road from you at Port Stephens and have recently built a 280ah battery and have another four cells and BMS on the way. Hope all goes well for you in your build.

:) What size fuse is in your inverter?

My apologies but realised the link was missing. https://www.amazon.com/MakerHawk-Electronic-Adjustable-Intelligent-Resistance/dp/B07F3NHHST/ref=sr_1_6?crid=25TIR9KBW09EU&keywords=battery+capacity+tester&qid=1661939324&sprefix=Battery+capacity%2Caps%2C282&sr=8-6

I'm from Port Stephens NSW and I must say what a neat set up. I joined here mostly to learn the battery side and for my caravan but I just had a 9.9kw system installed at home. Love your comment treasure. Yes the countryside is beautiful in ways and as you say so diverse. Almost the size of...

It is possible to use an inverter for your coffee grinder and small espresso machine but again it will depend on the wattage of the machines as to how much power you use and the size of the inverter needed. I do exactly the same when camping but I have 570ah of battery. My coffee grinder is...

If I were to be buying a LiFePO4 battery then Aussie batteries would be my choice but I have built my own by buying 280Ah cells and a BMS from from China. Amy has a good reputation although you do pay a little more but you can also buy your BMS from her which saves on postage costs...

Sry but I just saw the photos of your existing system. If it is just the batteries that have failed then why don’t you just replace the AGM’s plus add a few extras. Is that a 12v or 24v system that is currently installed? The system will probably run your washing machine, and probably your...

No there appears to be no other reset options now as it appears that they have changed the app again with an update. I too have one cell that shows a significant voltage difference but I haven't yet tested the cell with my meter. I will do that later and see if mine is misbehaving the same as...

Many will say don’t go 12v with a 3000W but the reality is how much power do you want to draw at any one time. You always make allowances for inefficiencies and that is why I bought a 3000W inverter. The biggest appliance I have run is a 2400W kettle which takes a few minutes and did not reach...

Ok take a look at the system you are proposing. 3 x 200W panels equals 600W although you will not get the full output. Connect them in series and this will reduce the need for heavier cables so your 10AWG and 20A fuse are sufficient for that. https://renogy.com/learn-series-and-parallel/

The prices quoted by the solar installers are after the government rebate have been taken into consideration. All that happens here is that the solar installer checks whether your property is eligible for the government rebate. Once you have chosen what size system your require you sign a...

This explains what you are seeing. https://aklectures.com/lecture/terminal-voltage-and-resistors-in-circuits/electromotive-force-terminal-voltage-and-internal-resistance Try it again and take a reading of the battery voltage under load. Once you have turned off the appliance, wait a while and...

At 280ah that will be for each pack of 4 cells. I have the Triron and like the Tracer it can be set up for Lithium. Buy yourself the Bluetooth module and download the EPEver app for your phone. I will keep eye out and help u through it but I’m in Australia so there will be delay to answer...

I have a 12 volt and have run my AC in my caravan with it which surprised me.

You can set the user settings for lithium charging. If you scroll down the manual in the attached link if give you a list of the settings to use. EPEver manual with Lithium settings Any controller that has user settings that are able to be modified to these parameters is suitable. Tim

Welcome Maggie I'm new too and doing a similar project. Good luck with yours. As requested by Smoothjoey can you post the link to what spooked you. Precharging an inverter

I have a 3000 watt Giandel and am more than happy with it. Not sure of the model number but I bought it recently. Tim

Hi Luke, I’m up at Nelson Bay. I read a lot of Wattsmatter’s posts as he has a fantastic setup. You have a number of options but to be honest I wouldn’t bother with the Bluetti. As pointed out you can buy a 200Ah battery from a 4WD store, which wouldn’t be my first choice , but...

A 100A BMS on each battery will with an approximate equal draw from each battery will allow you to draw 300a. A 3000w inverter will draw 250a @ 12v so even allowing for inefficiencies of the inverter you are well covered.

If you want to draw up to 200A from say two 12v batteries you can theoretically use a 4S 100A BMS on each battery. Obviously you also have to look at the permissable discharge current for your batteries.

Exactly! Did you charge your cells to 3.65v For the top balance. If you did and let them sit for a while you will actually see a small voltage drop. At 3.346 per cell you are close to 99% and if you really are concerned what the BMS states you can adjust it in the Parameter Settings. On mine...

Yes the guy that wants a third class of society in Australia so he can have slaves. Pure greed.

Well I have taken a look at my batteries today and the cells are all within 1Mv of each other. I have just let them sit for the past couple of weeks with without any charging or discharging. As I said, I had a significant difference with one cell but never tested that cell with a meter to see...

Put the correct size screw driver in. Hold firmly and give a good solid hit with a hammer.

Welcome Brian, There are many on Ali express that will take your money and sell you duds and a few on Alibaba that will do the same. Probably the best thing to do is find the name of the seller and do a search on here to see if anyone has left positive reviews. Take a look at Amy Wan from...

I use an EPEver Triron and I have no issues with it. Buy the Bluetooth module to go with it and set the App up on your phone and you can see all the data you require.

I have an EPEver Triron and dont have the documentation with me nor can I remember the settings i used but they will be the same as listed below. On page 24 of the link below are the LifePO4 settings that you can use but double them as you are now using a 24v system...

I did see that you were also asking about compression somewhere but couldn’t reply to you. There are those for compression and those that can’t be bothered. I actually compressed mine at first then just simply clamped them up and taped them together before removing the clamps. At between 3000...

Great to hear that you managed to succeed. :)

Set your charged setting on the Shunt to 14.6v. Set absorb to 28.8v Set Float to 27.6v Put some serious current draw on your system like a 1000w heater, 3amps at 24v is just a trickle. You seem to be overthinking the role of the BMS and what it actually does. It does not make the decision of...

Hi Wattmatters, yeah i been reading lots of your posts and you have built a beautiful system :). Have you looked at connecting into the grid or aren’t you allowed? I purchased cells from China for my caravan so have 560Ah@12v, but have an itch to buy some more :unsure:. That of course means...

Your 100Ah battery has approximately 50Ah capacity so if your inverter remained switched on and as Mike says uses 1.5A per hour then in 24 hours that is 36Ah. That is what you need to replace each day plus any additional power you use. Although your panel can produce 16A under ideal conditions...

As I said…put the best fitting screw driver in and give it a good bang with a hammer. It is the same principle as removing the retaining screw on a vehicle brake drum. But take a look at your screw driver ends to make sure that they aren’t chewed up. Looking at the bottom screw it is chewed up...

Looks like you have another bad product. I can only suggest you send it back and get a refund as the reviews for that inverter are horrid.

You are 100% correct lol. You and i knew what I meant but we have to express it in every little detail for those that don‘t.

No you need to monitor each cell. The last thing you want to do is try and take shortcuts.

I could do the calculations for you but straight out you are talking about the weight of two adults and structurally your floor most certainly can take that. Without even looking at the stress grade of your floor joists at a 10 ft span they wouldn’t even have any spring in them let alone be...

The manual I showed you also does not have a dedicated setting for lithium batteries, this is because there are numerous types of lithium batteries which require different charge rates. Instead you have to choose the user setting and nominate the values listed under the correct lithium type...

To me it looks like some of the liquid has condensed under the seal or that there was a small amount there that has since evaporated.

Ok you have mixed things up a little between an inverter and a solar controller I believe your question relates to the solar controller. The link you supplied doesn‘t go to the product you are referencing. Untill we can see the specifications for the controller we are unable to advise you...

Just did a quick check whilst the rain has stopped and no the reset did not correct the negative display issue. Will wait for the software update if ever they release one but I have always known that it was working.

Yes, but you still connecting to the positives even in the middle of the busbars. Think about which way the current to the BMS runs irrespective of whether your + of one cell is connected to the - of the next cell. Just remember to take your busbars off to drill them as we don't want to see...

Lithium batteries do not require equalisation but under the user profile it is unable to be turned off so it is set to 14.6 or lower so it becomes like part of the absorption cycle. At the bottom set absorption time to 0 mins. Tim

Not sure but this may help you.

Ha Ha Stuart I’m an ex Alway boy living in now, sunny at the moment Australia :cool:. You don’t need aircon there but I’m coming over in August so get rid of them clouds.

I do it and many others do it. It is not a problem as long as you set the parameters the same on each controller. You may get one controller shut off before the other but your battery will be very near fully charged.

So on a rough calculation your feedback to the grid would almost cover the daily standing charge. Therefore you only have to consider the amount of electricity you will consume from the grid and whether it is cost effective as opposed to the cost of buying batteries. In my case it clearly isn’t.

Ok firstly that one cell is way over and showing 3.951v. You need to discharge that cell quickly or you will destroy it If you haven’t already. Unless you have a means of discharging the one cell then you need to discharge your battery and get that cell below 3.65v. Looking back through your...

My understanding is it is all about efficiency in that if you use lower voltage panels with higher voltage panels then the lower voltage panels will drag down the voltage of the higher panels. Some people will do all they can to obtain the highest efficiency possible and other will accept a...

In relation to your solar panels the type of battery does not matter. Your controller matters in relation to the type of batteries and the voltage. If your Rich solar controller is the one in the link below then yes you can use that instead of the Colman controller. Connect the controller to...

Just buy a mini controller as long as your battery isn’t Lithium. It is exactly what I have for my boat. Just leave and forget. Mini solar controller Just don't buy from Australia lol.

My pleasure, just keep in touch to let me know how it works out.

Hi again Missoo. Firstly stop worrying about the SOC shown on the BMS for the moment and lets get your battery sorted. Even if the SOC is showing 50% when it is at 95% the BMS isn’t going to use the SOC to regulate the maximum level of discharge as it uses voltage to do that. Here are a link...

Don’t even think about buying it! Everything about the advert is wrong so buyer beware. Firstly as pointed out it says 4000W when it isn’t. The inverter is nowhere near the size a 4000W inverter needs to be. the cables shown to the inverter are nowhere near the size required for 4000W. The...

Have you thought about putting a little solder in to fill up any gaps?

No need to apologise as it seems like you have enough on your plate. Hope it all works out for you. I need to do some tests on the Daly BMS to see how much they drain the batteries and why they didn’t shut down when reaching low voltage. At 0.2A it will take forever on yours. As mine are...

HI Peter, welcome. I’m actually up at Bulimba at the moment, live at Corlette, Port Stephens and on my way to Port Douglas. I have built two 280Ah batteries each with a Daly BMS and have no issues For my caravan. There are recommendations of where to buy cells from on this forum but more than...

At that price I wouldn't mind knowing which supplier if you would care to share.

Agreed, except I stole some of the poly chopping boards from the kitchen which my wife is still looking for :ROFLMAO:. The blue, green, red, yellow and white also add some colour and the board handles make great handles for my caravan batteries.

Hi Matz, Welcome, I’m from Corlette, Port Stephens. Hope you get addicted :ROFLMAO:

When you said you were looking at VoltX batteries and I saw your nic then I had a guess that you were. I think VoltX are only in Australia. I’m at Nelson Bay NSW. Glad to see you got your battery going :).

Welcome, I have just had a 9.9kW system installed with an 8.3Kw inverter, but I’m in sunny (supposed to be) Australia. Back visiting the UK in August. First thing to consider is when you actually use the majority of your electricity because if you can use most of your electricity in daylight...

Settings seem ok but I have my differential set at 0.02v. If your were charging when you posted that photo then why is the BMS allowing the battery to be charged if you have a differential of 0.074. You have indicated the balancing to commence at 3.4v but what are your cell settings to turn...

The last post alerted me back to this topic and just wondered how you went Maggie? Tim

Yes ther are plenty of incentives to install solar here. I’m on a one year contract so I am able to change utility companies if I want to after that. Some of the companies offer plans to install solar for you but then you are tied to them for about 7 years.

Great to hear :) A great warning but i think you will find that he means 10AWG from his solar panel to his controller ;)

The SOC is not an accurate measure of the actual state of charge. I have two real Daly BMS’s and mine are out significantly even though the voltages on each battery are the same. I can actually set the SOC on mine to whatever I like but really 1.3% difference in the SOC is nothing to worry...

Consider that solar blankets laid flat will produce about 50% of the rated power. Even tilted then you will struggle to get 80%. Will take a look at the Victron for you.

Just came across this thread. Australian Standards are not laws and are only enforceable when called up by legislation. In other words there has to be Acts or Regulations under Federal or State legislation that call them up then they become referenced documents and they can then be...

Welcome Louise, Sorry to hear about your long term Covid and I wish you a speedy recovery. What part of the UK are you? I’m originally from Newport South Wales. Winter will be hard for you especially with little sun so firstly you may wish to consider a backup power source like a generator...

Ok what you first need to look at is your power consumption as you want to run your fridge all week. Is it a 3 way fridge? What is the power consumption on 12v? i think it will be way more than your battery is capable of providing. it would be more economical to run it on gas.

Great news. Do you have insurance cover for your house?
