Hey guys, newcomer here.

I purchased a house with a 3kw solar system.

It was some kind of dodgy back yard set up, not done to regulation. No electrician would work on it. So I asked an electrician to at least disconnect it so that I can use the parts.

I have a 3kw charge controller hanging on the wall. A heap of batteries. And some solar panels on the roof. All disconnected.

I'm going to get some photos and try to get some specifications to post here so that I can get some advice.

I don't want to hook it all back up because I don't trust myself. I'll get electrocuted! I know me..

SO! My plan is to separate the panels and batteries into smaller groups (not powerful enough to get electrocuted from). I'm thinking 3 batteries, 36volt? or something like that? Mind you, I know almost nothing about anything.

Then get some 36v charge controllers and build some little charging stations I can use around the house.

ie: I want to put a couple of panels above my office.Connect them to 3 batteries. Then hook up a charge controller and an inverter and see if I can't run my laptop with just that setup.

If all that goes well, I'll do the same above the lounge and see of I can't make another setup for the TV. So on and so forth.

I don't mind having to buy a heap of different charge controllers and inverters. Just so long as I can do it all myself, not get electrocuted and not pay an electrician several thousand dollars. I'd rather spend that money on charge controllers and inverters that I can re-use for different projects.

Anyway, that;s my intro. That's why I am here. That's what's on my mind and where I am at with my knowledge.

I'll get some photos and specs.

Oh, and I am an Aussie. I live in Queensland, Australia :)
 
Yep. Get some pics up and specs. Starting small and working your way up is a good way to learn. That is how I did it. Folks on here can give valuable insight.
 
Thanks Skinny76, Yeah, definitely starting small! A quick peruse of some recent threads here testify that it's a good idea to start small! I see the word fire mentioned a lot lol. I am DEFINITELY going to be cautious!

Just a few pieces of advise:

Don't go 36v, it's almost impossible to find stuff for. Go for 24v or straight to 48v if you want to have a larger than 3Kw system.
3Kw of panels at the average 4 hours of sun should get you about 12Kwh of charging on a good day. That's not bad!
If you take your time and stay aware of basic safety steps it's really not that bad. Just don't wick teh wed wire.
Doing multiple small systems is going to be fun! Be aware of the math and give yourself fudge factor.
Don't worry about grid tie, it's more hassle than it's worth.
Post pics as you go, we all really enjoy that. :)
 
Rednecktek, no worries. See, I am learning already. 12v ot 48v. Not 36v. Check!

I'll definitely take some photos. On the weekend, I'll go take a pic of all the stuff that came with this house when we bought it and make a separate post about that.

pollenface, I live out west - a little way out of Charters Towers :cool:
 
Welcome!

Lots to read on here, best to peruse similar threads and read advice and follow along.

Being an electrician since I was 16 makes it difficult for me to sympathize with knowing nothing, but I CERTAINLY agree caution is warranted.

Hi, I started off knowing zero about solar, batteries etc, everything I now know came from YouTube and this forum, took a while,but I learnt a lot.
