The inverter can not maintain it detects the voltage and current starts working rejected start voltage of the inverter is preferably at 11-13V.
Solution: 1
1, Bold battery positive wire to the cigarette lighter,
2, use the wire to the negative battery cigarette lighter,
3, considering that the battery is connected to the cigarette lighter has a 2M long wire, select 2.5 square or larger wire connection

Q: 500W inverter I used 20A / H is more than 200W battery with fixed appliances
A: Yes, 20A / H is at best only battery Pure sine wave power inverter charger 200W or less, if you want to bring Electric 500W or less, please select more than 60A battery,
