4000w 12v

These load modules were made especially for this project, but can be used for amp testing too, for sure. Each resistor has the rated power of 50W, so, 8pcs = 400W.
Guys, I am developing devices, I am not a filmmaker ;) I found just one pic from the testing process. As I remember - right before the load was connected.
On the scope - signals of 400/12V module PWM; signals of synchronous rectifier's.testing_1.jpg

so the 4000w load test has never been tried?
I was curious how hot the mosfet was to pass 300A+ current
300A at 1 mOhm (assuming rds on) produces 90W dissipation, what mosfet do you use?

Good work man,
I used factory made 5000W inverter at 48Volt (54V to 57V when charging) for VSAT equipment.
I just imagine your inverter will pass 4 times current than mine
