## PSU module connection
Using standard XL4005 module:

| Main board | XL4005 PSU        |
|------------|-------------------|
| GND pad    | PSU  ` - ` input  |
| 12V pad    | PSU `+` input     |
| 5V pad     | PSU  `+`  output  |

## PZEM module connection

| Inverter               | PZEM module |
|------------------------|-------------|
| AC IN (N)              | Pin 1       |
| AC IN (L)              | Pin 2       |
| PZEM coil (black wire) | Pin 3       |
| PZEM coil (red wire)   | Pin 4       |
