Hello All
I am wondering if someone would have a Madness Power board available to sell.
I am in the process of building a 6kw OzInverter and unfortunately Madness is out at the moment.
Thanks
Andy

Hi Andy,
I did purchase 2 power, and 2 control boards that I haven�t done anything with.
Maybe if you have extra components we could do a swap for one of the power boards.

andymc70 is starting an inverter build so I thought it best to get a bit of info
ready for him here.

Here is some info of the nanoverter PCB, Madness's 6kW PCB and firmware.

latest version of the nanoverter
(includes top and bottom PCB rendering, schematic and BOM)

2019-05-05_081432_Nanoverter_D_Gerbers_Others.zip

nano1 firmware:

nano_1_v7_no_bessel.ino.zip

nano2 firmware:
this is what I use in the house inverter, running for 1 year now.
The run/stop switch is continuous, that is, you have to close the normally open switch
AND KEEP IT CLOSED to enable running the inverter.
The code also expects a serial port type 20x4 LCD, connected to the 3 of 4 pins of the I2C connector. See below for more details.

nano2_5_ac_current_sensor_continuous_on_off_control_softserial.zip

nano2 firmware that uses a momentary contact push button to start and stop the inverter, also it supports i2C 20x4 LCD.

nano2_4.ino.zip

you will need to load the LiquidCrystal_PCF8574 library for the Nano into the Arduino IDE. AND maybe alter the I2C bus address in the nano2 code to suit your LCD if you use the I2C LCD.
The firmware makes calls to display and control the LCD and these calls will stuff up the running of the firmware if the ICD LCD is not present.
That is why I like the serial port LCD, the firmware works fine with or without the LCD.

Madness's 6kW board's BOM:

5 100uf 63v electrollytic cap
6 104 50v 2.54mm Caps
1 104 50v 5.08mm Caps
1 10uf 50v 5.08 Cap
4 10nF 103 3KV capacitors (Snubbers)
6 100V 10000UF Electrolytic (Can) Capacitor 35mmX60mm
1 4.7uF 250V Metallized Polyester Film CBB Capacitor 475J,
2 CAPACITOR, SAFETY, 10NF, 250V, 20%
1 18V Zener
2 UF4007 Diode
1 Tip35c
4 Tip41c
4 Tip42c
16 - 24 HY4008w MOSFET
16 - 24 IN4148 Diodes

1 120 Ohm 5W Resistor
5 10K 0.5w resitor
4 47 Ohm 3W Resistors (Snubbers)
4 5k Ohm 0.5W
4 20 Ohm 0.5W
16 - 24 10 Ohm 0.5W
16 - 24 20K Ohm 0.5W
4 MOV's Metal Oxide Varistors (for helping protect against lightning)

the code for a serial port LCD

nano_serial_to_parallel_LCD_2.ino.zip

very simple to make, you need one nano, one 20x4 LCD and a handful of wire.

Hi Poida et al,

Seeing you are so helpful, have a few questions,

I was all set for my inverter build a couple of years ago, but new job, relocate cities, blah, blah.
So, keen to get back into it, but after a break of a couple of years finding all the posts somewhat confusing.

I purchased the �8kW� madness boards, are these the same as the 6kw boards you reference above, or was this a new revised board.

I also purchased mads control boards and half the components. As I already have this would you recommend having a go, or scraping it all and starting fresh with the nanoverter

If so, does anyone out there have spare nano control boards to buy.

Thanks

I have used the wrong name, I mean to refer to the 8kW boards.
These are very good. The totem-pole gate drive is a good design
and adds a high degree of robustness to the system.

renewableMark has used both control boards and I think he prefers the nanoverter.
I prefer it too but I am biased.

I still have 5 spare boards after sending 2 to andymc.

Thanks poida,

Will do some more research and get back to you.
In two minds to stick with what I have or to go with the nano where I possibly could get more support if needed.

There is nothing wrong with the mad control board.
It's a bit more fiddly to set up with the sensors etc, but a knuckle head like me managed it.
If you already have the bits, just build that.

RenewableMark, what i have seen of your builds, you are defiantly not a knuckled head.
Quite a capable technician.

LOL, nah mate, I'm just good at following instructions.
I couldn't design a light circuit.

There are a lot of clever and helpful people on here, I'd be buggered without them.

Edit, I found 4x temp sensors that suit the mad board if anyone wants them.

Thanks to POIDA
I have received the controlled boards, can not believe how small they are, its unbelievable that they can run a home.

Thanks to renewablemark highlighting the minimum build for the board. I have order the parts, now the long wait until they get here.

ryanm said Also have a couple of spares.

I have sent private messages to RYANM and STEVE, would love to hear from you guys regarding the POWER Board. Still need to get a hold of one of them. If anyone else could help me out that would be great too.
Thanks
Andy
