The fan inside is quite noisy. I did however solve this with a buck converter to drop the voltage to the fan. Sure it will spin slower but i think cooling is sufficient anyway since im only using like 15 amps.
I have been using this for a while now and I can only say that the voltage isnt very stable. It is advertised as 41.7 Amps but it when i have about 15 amps of load it cant handle it. I have tried to talk to the seller about this but not much help given. So with that said i can not recommend this product or seller.
not exactly what i expected
