This is a modular solar grid-tie/on-grid inverter main board.
It uses:
- 8x BuckBoost Power Conversion Module
- 2x Grid Polarity Switcher Module
- 1x Inverter Control Module
- 1x MPPT Module
Features total output power of up to 1000 W into 230/240 V 50 Hz grid (depending on the modules and components used), input voltage range of 120 VDC to 300 VDC (150 VDC to 300 VDC for MPPT tracking).
Single sided PCB, 0.8mm minimal spacing, easy to mill.
Overvoltage, overcurrent and overtemperature protection.
External optocoupler isolated output power limit signal input, eg. for grid outflow prevention.
Screw mounted 3D printed module stand rails, print kit and cut apart with scissors.
