did a check, my inverter's grounding screw has a connection to the negetive dc input, the charge controller doesnt (as its just the heatsink) also reading about dc/ac confusses me more. ive scoured lots of websites for something maybe a 10 year old can understand. so far im taking it as...

ahh i see, doing the chassis grounding for the charge controller and inverter should be all i have todo?(the screws with the ground icon on each to the main's green) sorry for any frustration ahaha. the whole grounding/earthing thing has put me in a big confusion. really have to use simple...

So grounding as in taking an off branch from each negetive cable to the main's earth? not using the indicated 'ground' screws on the inverter and charge contoller as they are 'earthing chassis' instead?

I have almost finished my first ever setup from the 'Build Your First Solar Power System!' video (with parts from where i live. Australia) and spare pannels i have. from the video i should be able to pretty much go, but i got to thinking of grounding. The more i researched the more confused i...

I may wait a few years before trying again, or when my bill changes. scrounging around for deals it looks like i lose out a little (even though the setup will last years) or i might save for $3k for a decent test build. over the years of it running, hopefully ill pickup a better job. $3k over...

That may work if i was american. Australia likes to put up the prices.

Should of said im AUD, though i guess calculations are the same, our sun hours are higher though, they say roughly 8 hours i think we had in our notes give or take depending on cloudy days. Its not connected to the grid so its plain dumped surplus on what would be made. solar > charge...

Found this one for a 250Ah 12v and slightly cheaper because its on sale. 1600 at 100% and rated for 15years of service. Its confusing me that Lifepo can use 100% but it seems to suck compared to just using a AGM that has the same 30-50% requirement. just that lifepo's are lighter and more...

Hello, im looking for some feedback if its cost effective purchasing 2x batteries (them alone) compared to if i just paid my electricity bill. A few points are: - I dont have batteries - no fuses/breakers - no charge controller - I pay ~$0.2 per Kw/h - I do have spare solar pannels My friend...

@Jordi Regarding the 18650 pack, i did some research with my friend and found these quantium batteries that are best on price as well as being in a physical store if anything were to happen. Appologies if you want to read their description, the text is faint, highilighting should help. two of...

Took a little refresher off thinking about the setup to come back using a few calculators. To run my 500 24v inverter (going at 450 Watts at 24V continuous) I'll be basing future 'needs' running my inverter at 450 watts or roughly 90% from full throttle, i dont like maxing machines. Which...

the BMS is under the curcuit board, i had the capacitor only on while testing and seeing how it works. I generally disconnect everything after having a look. cheers for the encouragement. at first when learning about it all and conversions, ohms, watts, volts, etc it was mind boggling, ill...

AGM's interested me at first, but the thought of only being able to use a set % feels like a waste to me, I havent studied in any electrical classes or been in this hobby for too long to know pros/cons about most of the basics, appologies if it feels like im skipping what you are all saying. im...

I'd need to find an australian counterpart. Using Deepcycles look like less hassle and work, need to research into reliable brands that we have here. Using non lifepo4 seems a bit of a drawback since i would have set ammount i can use of the batteries % but for a testing rig it shouldnt be that...

You're fine, easily understood. My plan is to power a shed. first using the 500W inverter then expanding. learning as i go and making bigger systems if i want. I dont have things like "i want to power X,Y,Z" getting a working 500W inverter in full use would be great. My grandfather has a bigger...

the BMS ebay description says max 2A per layer, wouldnt 1A be more fitting for 18650s? putting it down to 0.8A per layer? i could buy better batteries with a actual brand behind it maybe these or other options. I dont know where to begin looking (australian based) so many types of chemical...

This is the inverter and as for its own draw 0.7A. 2200mAH is low, if i made it like 8800Mah, would that increase the charge controller and solar panels compared to the current 2200 setup? making a bigger battery bank my main focus prior to charging needs. I plan on using what ever the...

Yes, theres BMS attached to the battery pack holder. So i should increase my capacity by 10? being 10p6s (10 of the same stacked ontop of each other) unsure how popular these pack holders are but they are better than trying to make my own.

Heyo everyone, im new to solar setups although i have tried watching videos and tutorials. Ive been tinkering with a small battery bank with a friend for about a year and progress is kinda slow. Living in australia it can take a while for parts to come in. Skipping most of the background, Im...
