I'm up for a kit and a few spare PCBs.

yahoo2 said I might be interested in a goodie bag of components so I can compare what I buy with what you have built with.

I really struggle with delays on freight and post, ordering the wrong part and having to reorder can set me back at least 6-8 weeks. Kinda ruins the fun.

Not really in a position to supply all the bits ATM. To start doing that would take me that same time to get the parts.

I just meant with the kits, I have got plenty of other stuff to go on with ATM I cant see myself building any inverters before the summer. unless someone twists my arm. plus I am out of transformers, I think i might talk to the place in Adelaide that Tony suggested and see if I can build one with their core.

of course, as soon as I order one, old grid inverters will pop out of the woodwork.

I'm confused, no wait... maybe I'm not...

Aerosharps seem to be hard to find now. I would be very interested to see how you go with that transformer manufacturer. Even if we could find a source of the cores.

Has anybody had any experience with these current sensors can't find much information about them myself.

Gary, I use on of these C/T
for my inductance tester.
Its similar and there are bigger Amp versions available.
The nice thing is the single 12V supply for my use.
It works fine and has the advantage of opening hole.

That one is AC only, I think madness wants an AC/DC version, like hall effect.

Thanks Klaus and Mulver,

Correct Klaus I want to measure battery current for the charge controller, this will allow current limiting, measuring State Of Charge and showing charge/discharge current. Current limiting is important for protecting the batteries from excessive charge, with cheap solar panels there will be more and more people putting up heaps of panels to get through cloudy weather. But when the sun is out and you're not using much of that power you may need to limit the charge rate to the battery.

That sensor you posted the link for Klaus is not working but I found it here. The 400A version is twice the price of the one I was looking, I don't think the split is that important.

Sorry about the link, I think my cut & paste job was a bit slack.

I only got the 50A version for the inductance tester but am surprised you are looking at 400A

. I use an ordinary 100A/100mV shunt with a 200mv meter at the moment at my battery. That is plenty for charging my 10KW lithium battery bank and it survived 150A+ discharge during my inverter heavy load testing, just got a little warm.

The split part is useful if its not a permanent connection, however, do check that the solder/crimp lug at the end of your cable also passes through the hole

of your fixed version.

The +- 15V supply might be a bit of a nuisance though.

The other one I am looking at is 300A, it is not just for charging but for discharge as well. My Inverter earns it's keep, the accuracy of your 100A shunt would suffer as it heats up at 150A. There are times I am charging at 120A, but that is something I want to limit back to under 100A.

I could buy a 10 Lugs for the difference in price for the split type.

Some people are waiting for PCBs so I have decided to go ahead with the big power boards, control boards and fan controllers. I am still working on the solar regulator boards and want to wait for components to arrive to test before ordering any number of them.

Prices depend on getting 25 orders for each board, here is the costs.

Big 24 MOSFET Inverter Power Board $25 each
Control board with LV shut down etc $10 each
Fan controllers $5 each

A set of boards weighs 310 grams up to 3 sets would be $15 (1KG) for more 3 KG is $17 for express post within Australia.

Those that want to go ahead let me know I will PM you my Paypal details.

If you did not put your hand up before or want to increase your order it is not too late to order now.

Happy to post internationally, let me know where to and what you want I can get a price. Or go to Australia Post my post code in Australia is 4556.

Hi Madness,

Postage and the tracking number can get costly.

From Europe to Australia for my OzInverter Power board, A4 size, control Board and cooling board and the A4 book is about 22 Euro or �20 GBP. Its standard post with tracking number and takes about 14 days.

Everything is possible, just give me time.

3 HughP's 3.7m Wind T's (14 years). 5kW PV on 3 Trackers, (10 yrs). 21kW PV AC coupled SH GTI's. OzInverter created Grid. 1300ah 48v.

Yeah post costs have increased a lot here lately also, 1 KG sent to France from here is $37.00 AUD via Economy Air and takes 9 business days. There might be some of our friends from across the ditch (New Zealand) that may be interested, 1 KG sent there is only $11 AUD and takes 7 business days.

PLEASE NOTE

I have built the fan controller on to the control board so you do not need the separate fan board now. To build one inverter you just need 1 X Power Board and 1 X Control Board.

Also I need payment to secure your order, I have had too many people tell me they going to something lately and then failed to follow through. Don't worry I am not one of those kind of people.Edited by Madness 2018-04-29

I see there are different arduino nano around
Atmega 168 here

and 328 here

Which one do I order?
