i connected to level 2 for charging this morning and measured some temperatures inside the box.
started at 8am, everything at ambient, 76F
checked at 9 am, ambient at 80F; 10am, amb at 83
water pipes
MCU 88; 94
OBC 89; 94
EMI filter top (joe's doghouse), 102; 114
side of obc case, 96; 98
large cap, 127; 144
large inductor rear, 208; 194
transformer rear, 195; 184
