CET DCI/G4 3000VA正弦波逆变器，求助！！
输入DC40-80V，输出交流电压220V，输出频率50Hz/60Hz可选，功率3000VA。尺寸：536x348x222毫米，重量约17公斤。
偶得100%新1台，查一下淘宝，2手7,8成新都要3000.[s:274] [s:274]
上电了就是不输出-----，求高手教教我。
Maximum input current (3 KVA) < 86A at Sout = 3 KVA at Uin min
< 138A during t ≥5 sec at 100% overload and 48V input voltage
Nominal value of output current 13A at Uout nominal = 230V
Short circuit output current > 36A peak during min. 5 sec
