Figure 1.

Figure 2.

Pebble INVERTER CONTROLER FAN7310 have 2-way of the PROTECTION MODE. 

1. OVP[Over Voltage Protection]

: If the Voltage of the series capacitors C10 & C15 is over the 2.0V, the 

Inverter latched-off.[See the Picture1]

2. OLP[Over Load Protection]

: If the inverter output harness is opened(No-output current), the base of the

Q1  turns on and chage the C9 ovter 2V and then, the Inverter latched-

off[See the Picture2]
