I decided that I will need a portable EVSE. I ordered some parts from OpenEVSE (board, display, CT and J1772 cable). I have two Crydom D2450 50A solid state relays and I will first try to use them, if they get too warm I will switch to a contactor. I have some questions about how the board will come set up: for one contactor or for two relays. I will do some reading about that later.
My main question right now is if I need to use 240V fuses or not. My goal is to keep everything safe and as small and light as possible. 40A fuses and fuse block will take some space. I was thinking of finding fuses that will bolt one end directly to the relays, eliminating the block and some wiring. I will still need to support the fuses properly. The 50A OpenEVSE does not seem to have fuses included in the kit. The 30A does. What is the rationale behind the decision? How important are those fuses?
Thank you.
