You could try a jig to get all of your holes the same spacing. Drill the first hole in the bus bars and sit that on a pre-made piece of wood with a bolt in the position of the hole, do up the nut on the bolt to hold the bus bar in position and clamp the wood in a vice on the drill press and...

They look very interesting, I might buy one for my 12v fridge for when i go camping if you give a good recommendation. Ive recently gone off grid and bought some Solar King batteries but like the idea af being repairable and a metal case.

So after much googleing i have found what seems to be the answer to my question. The mc4 connections all join to common bus bars inside the unit so connecting to them is joining in parallel. http://disq.us/p/1ev38q2

I stopped using the ipad keyboard and use one from the app store, lots more features and no missing t's. Not that i noticed any letters missing before i changed but i wanted the < and > keys to move the cursor.

@gnubie Thanx for the quick reply. I had a look and can get a Combiner Box that should fix my problem. The box can handle 40A in 4 strings of 10A each and will take 250v input/output, so that should see me right. Im amazed at the things and affordability of some of this stuff. Thanx Dave

This might be of some use? https://www.ecoonline.com.au/solar-pool-heater/

Thanx for the reply, didnt think about the fan noise. Ill keep looking, id really like to get a Victron Easysolar but as you mentioned the price is a bit prohibiting at the moment. Ive got a property on the market and once that sells ill be set to buy components to build a good brand name...

Hi, I needed a battery in a hurry to replace my failing 12v 100ah FLA and bought this one as it was close and available. 12v 200ah battery I now want to make a 200ah 24v system with an all in one, in the battery specs they say that it can be put in series with a max voltage of 30v, "Maximum...

Battery Powered Fronius AccuPocket 150 Welder :eek: Not sure on your budget but WOW. Dave

Thanx for your reply @gnubie the existing battery is 3 months old and very lightly used, so maybe 10 cycle max. I have used it to power a small 40 ltr engle 12v camping fridge and cpl of LED strip lights. I have 3 x 250w solar panels in parallel running through a 12v 30A PWM SCC. There are 6...

It looks like the expansion kit might come with Y connectors which would suggest a parallel connection? You will need a tool to disconnect the existing MC4 connections.

Thanx again @gnubie that sounds like a plan. Ill try to remember to update when it all happens. You have been a great help. (y) Thanx Dave

Says "shipped from China" when i view the link, cant find any mention of Australia.

Sorry, yes he says he is in Australia, didnt see that.

It depends on who you listen to I suppose. There are 2 sides to every story. Dont just rely on the mainstream media, But this isnt the place to discuss it. Dave

Well ive bought the victron easysolar 24/3000 150/70, some batteries and panels and am making electricity. I hooked up the 3, 250w/37v 8.25amp(i think) panels that i had on my 12v system, they were in parallel so the results were pretty average so i connected them in series and got a lot better...

We pay $0.40 kwh here in South Australia. We have to pay for Elon Musk's battery that he installed down here. Dave

These come in different temp ranges. https://www.jaycar.com.au/normally-open-thermostat-switch-50-degrees/p/ST3831

Thanx for your replies, ive got a better Bluetooth speaker and also have a car radio and some speakers that ill hook up and check the power usage. Thanx Dave

Has anyone had anything to do with the EPever all in ones? Interested in peoples opinions. Im looking at the 24v 3000w 150v 60a version. UP3000-M6322 All in one

Australia here, Im going to buy one for my Off Grid System, was going to buy the MPP one but the Victron has a 5 year warranty + if I have a problem with it there is a service center in my city rather than return the MPP to Taiwan? Victron EasySolar 4000W 48V Inverter/Charger Dave

The better Bluetooth speaker thAt i have is charged via a 240v power brick (Australia here) and i would prefer to have the system powered by 12v. As i already have a 12v head deck i have ordered a pair of these Speakers to give a try. Apparently they sound pretty good. Here is a long video of...

Hi, im trying to get my head around an off grid solar system that I want to build and have come upon a question that I cant seem to find the answer to. I want to hook my 12 250w Panels solar panels up with 3 s, 111.3v and 4 p, 35.9A but it seems that the MC4 connectors have a max rating of 20A...

1000 cca? Not sure how many emergency starts you would get from this. Looks like it must be a bms bypass maybe?

Im using my Bluetooth speaker in my soon to be solar powered shed but was wanting something a bit better. Ive got a car stereo but it says that its 100w, 25w per channel x 4. So at low to medium volume do they actually draw 100w? If i only run 2 speakers would it draw max. 50w? Whats...

I had a look on the Victron site and it looks like you can pick your voltage and frequency in the setup. If you scroll down on their page below there is a picture of the settings. Victron Configure Dave

Sorry dont know what happened with the double pics. Cant find a way of deleting them.

Hi all, im working my way towards my first off grid solar system, my first anything system really. Has anyone had any experience with the the Victron Easy Solar ? One of the things that appeals to me is the 5 year guarantee, I can also buy one locally. Thanx Dave

I wasnt aware that you could weld SS to Aluminum.
