 # SMA-SB2500-Off-Grid
-Try to open source the grid tie solar inverter SMA Sunny Boy SB2500
+The grid tie solar inverter SMA Sunny Boy SB2500 is a beautifully designed transformer isolated grid tie inverter. It is probably possible to convert it to an off grid batter inverter by reprogramming or redesigning the logic  board
+
+
+![image](images/blockdiagram.png)
+
+
+The inverter has an H-bridge with 4 IGBTs (SKW30NF60) driven by IR2113S mosfet drivers. These drive an 2mH inductor + 4.7uF capacitor step down converter and then a isolation transformer 153V primary/230V secondary 9.6A. On the grid side are three safety relais, EMC filtering and a measurement transformer for the logic board the measure the grid voltages.
+All the logic is powered from the DC side, several voltages are generated using a switching power converter which generates all the drive voltages for the IGBT drivers and the logi board.
+The logic board contains an SAFC808 microcontroller, probably with an interchangable AT70C020, 2 MBit memory chip, for grid monitoring and sequencing. A DSP56F803 from Freescale provides the switching waveforms. 
+
+The layout is drawn in Kicad. 
+
+Exported images (probably not up to date) are in the images folder. 
+
+The src folder can contain the Freescale DSP code.
+
+The datasheets folder contains datasheets of most of the electronic parts in the inverter.
+
+
+# Already known
+* Switching frequency 16khz
+* 250 - 600VDC max input voltage range
+* 2200W nominal power
+* It is probably challenging to reuse the logic board, as one of the microcontrollers is OTP, maybe it can be bridged and only the DSP used. But then you need a [Freescale USB TAP](https://www.nxp.com/docs/en/user-guide/CWH-UTP-UG.pdf) JTAG programmer to program the DSP. The development environment is not easy to download, but it looks easy to use. 
+* The [DEFCON 18 badge](https://media.defcon.org/DEF%20CON%2018/DEF%20CON%2018%20badge/) has used the same development environment and might be a good place to download the development environment and some general guide.
+
+# Already done
+* Basic pinout of the logic board connection in Kicad
+* Basic layout of the power board important parts in Kicad
+
+
+# TODO
+* Check if pinout is correct by measuring the voltages on the logic board connector 
+* Check all voltage ranges of the voltage measurements on the logic board connector
+* Try to reprogram logic board
+* Or design new logic board
