I feel like there no factor for poor weather. I think you should consider at least 4 days of battery with no charge to ensure you are online for the majority of the time.

I second that renogy customer support is absolutely rubbish. I also would not purchase from them again purely on this factor. (FYI - and there renogy rover Li 40 controller is $hithouse as well).

Hi all is anyone feeling like educating me? I have a Daly bms, but the manuals don’t explain the settings and exactly what they do / affect. I can’t find anything else in the forums similar. I’d just like to develop a deeper understanding of my system for future knowledge and would appreciate...

Thanks. Just found this thread. Shipping costs are the gotchas to here.

I'd be interested as well in what raw cells Peter could supply and what the costs would be.

This has been such a great thread to follow. I was going to ask Steve why he though another scc wasn’t necessary, but you’ve answer that for me solar queen. I’m voting for going 24v and a new inverter. It really seems like the installer missed some basics here. Send him an email with a link...

Thats a fantastic idea. we waste so much van water on showers!

Thanks. and to answer your previous logistics thoughts. Most here accept there is a shipping cost and build it into their calculations. Quality and value is the foremost priority for many.

are you suggesting something like https://www.ebay.com.au/itm/TYPE-3-Stud-oil-strainer-cover-size-Stainless-Steel-M6-M8-x-21-N0144781SS-/362001987818 directly onto the battery, and having the fuse holder hanging off it?

Ill answer question 3 and 4. 3. 24V inverter & midnite 250. Midnite can charge 62amps at 24v each. So if you had 2 of them you'd be producing 124amps total. 124ax24v = 2976w. So you would be using all of your panels power. The inverter size it totally up to you. It depends how much power the...

Hi all I’m looking for (but can’t find) a good guide to understanding scc settings. i.e. high voltage disconnect Charge limit voltage Equalise charge voltage Boost charge voltage Float voltage Boost charge return Over disc return volt Low voltage alarm Over disconnect volt Etc etc I’d like...

Im keen on people suggestions on the best 8 cell, 12v layouts to wire up the bank in.

@GeorgeV7 thanks for sharing this scared experience. It’s a great wake up call and learning for us noobs. Let us know how you go and what bms you grab

Opps. Any idea who I am thinking off

Update I really missed the obvious in the all in one Install. problem is solved byshore power - direct to all in 1 - charger. all in one - switchboard. It does it bypassing automatically and everything will work. Also means no live power to the external plug (very good point). been and...

I did prove it to them, and my support got escalated, proved it to them, who passed me to the Asia pacific region sales support, who didn’t accept it and escalated it back to tech support. In the end I just gave up. I had a battery monitor showing the amps, and a clamp meter confirming it, verse...

your spot on. i just need the driver and software (which i think i has) to make it all work. I am trying it all again now :) thanks again. ill let everyone know how it goes.

They pull equally from each battery so that’s why it doubles and the bms isn’t an issue. Per bobs post just check the cables and connectors are the correct rating for 200amp.

Yet the aus government knocked back The 4th telco merge because they didn’t trust that Huawei equipment was ‘in Australia’s best interests’ due to perceived backdoors built into the code allowing remote exploits. Everything comes with a price tag, sometimes cheap is not what it seems.

Gold, thankyou!

Not sure if this helps now. I asked them after I asked you, they sent me a link i couldnt find elsewhere. They have both wireless and wired controllers. Here an example (i was only after 2500w). https://www.aliexpress.com/item/4000785699268.html?spm=2114.12010612.8148356.11.5ecd300aAp76p9 the...

Connections are all right and double checked. this only happens at the end of a hot day, not I. The morning too. Seems to be heat related.

Ah Cool, i follow now. How do you ensure a good connection between the busbar and battery, do you use any kind of lubrication to ensure a better electrical connection? are you using stainless stud washer and nuts

Hey not sure how useful this is, it I prefer instant gas hot water, we use a gas over, gas grill, gas cooktops. I try to run a 12v van except for the necessary 240v (aus) appliances like laptops. Gas is great!

thanks DZl I didn’t show the bms for simplicity. It’s a Daly 300amp. Bit of a beast, bigger than I expected. I think a breakers replacing the 2 60amps Fuses is a great idea. I’ll lease the fuse though and the battery isolator. Prefer this setup for the critical high Amps load.

They are sureflo pumps. The pressure switch is always triggering but it’s by design, I just wanted to isolate it from the lights.

Really... that’s sweet. I also have a backup generator even in the caravan. My advise is to work out your loads and what you want to store etc. but be okay with the idea that if you run a gamer story one of twice a month to recharge the batteries that’s a okay. May be the difference between...

That is very cheap! I just converted to aud. 8 cells would be $1300 aud delivered. For 560! Wow sounds too good to be true! :)

Same Amy, Same Product, Same customer service. Atleast, so she says :)

i havdnt seen the diagram, but now i have. That is wired in 2 strings, of 3 panels in series. the voc will be around 63v. and will be fine for the rover. (which was your original question). The only thing Id suggest is using different brackets. I use a bracket on my caravan which just glues...

Steve_S is guy to talk to He built a full 10kw system from Chinese imports, tested etc and could give you some really good direction on what to use. He's a bit of guru in my book. I just dont know how to tag people in. @Steve_S ? Search fir his name in the members list. he is up the top. There...

I don’t agree. If the inverter is powering the same circuit th charger is in, the AC power would present the same. I would expect. I can’t see how it can tell. Hence the original question.

Peter, just so i am clear, whats the life cycle stated on these cells your using?

thanks for essage they have also said to update the bms firmware. however, i cant seem to get the lptop to see the bms. I have plugged in the usb direct to laptop, but it says unrecognised device. the daly documentation seems to reference installing th CAN box software driver and the RS485...

Here is the battery is there. Way to try and balance them without opening them and going cell by cell. mid the amps going in are 0 is this still balancing or should there always be some sort of current?

I can run the ac off my 2400w generator so I am assuming the inverter will have the same ability. It is a big unit, so short periods more in a kiddie ‘I can’t sleep it’s too hot’ emergency. Inverter and batteries will be very close . Thanks for the tip.

Thanks gents For taking the time to reply. My concerns are: So in terms of battery cell setup, having 8 cells in a single line in a 24v setup, is this still going to charge all cells in balance? The same issue would be there for a 12v, 8 cell 560amp setup. But 2x 280 would only be 4 cells in...

Correct, being an all in 1 the charger is built into the unit

Hi I have an inverter / mppt / ac charger which could theoretically supply 120amps of charge. I was going to puchase the ANT bms but noted its max charge is only 50amp. Can anyone recommend something similar features (smart and temp sensors etc) thats still simply, relatively cheap, and has a...

They are a pure sin wave. The voltage on the generator is 241 and the sine is 51hz. that seems to run it. I dont think I can change the output of the inverter from 230 to 240. I can up the hz to 60. Am I likely to break anything if I change the hertz to 60 to test? Does anyone know if I can...

I was looking for a low cost solution. A 24v multiples in Aus is $2400

https://diysolarforum.com/threads/mpp-solar-disable-inverter-while-leaving-mppt-charger-active.6832/ heres a thread. the on/off is only for the inverter. Sweet :)

On top of an RV?? Context is important

it draws. AC on solar are difficult usually as they require so much power. but it just depends on your definition of AC.

Thanks so if ordered just the 4 cells there'd be no GST. Thats a good price :) Im convinced to go 560ah now and run SOC to 70% to try and prolong the life, basically 400ah at 'full' charge.

Unfortunately these are on top of a caravan so mounting anything but flat is not super practical. I could test the pael outputs using the pipe. great little trick.

Thanks Ped. Yes that’s the defualt LI profile. I just assumed it was correct. When in LI mode there Re only 3 things you can set. I’ve gone to user and set the parameters manually. It has straight away changed the battery monitor to numbers which look a lot more correct. Thanks! I guess...

Good Question 24v 8 pack, 280ah eve cells 3000w inverter peaks at 6000 for 30sec i think.

Are you sure thats the charge, not the discharge rating? I can only see 50amp charge ratings on them all?

i do have a shunt based monitor, but the lead cable is too short so i havent the cable yet to extend it. Trying to source something suitable without heading into any major shops at the moment. As for full batteries - this is not whats happening. I am running a 220 12v waeco fridge and a 12v...
