Wiring Diagram

Note: The wiring of 48V inverter is similar to the 24V inverter, and the batteries are connected in series.

Protection Functions & Applications

• Reverse Polarity Protection: Auto protection when input positive and negative polarities are reversely connected – The fuse blown out.
• Short Circuit Protection: Automatically self-protect when short circuit occurs – Red LED light ON.
• Low Voltage Protection: Automatically protect when in low voltage – Alarm first, the voltage continuously reduces, the red light is on and the inverter shuts down.
• Over Voltage Protection: Automatically protect when in high voltage – Red LED light is on, and the inverter automatically shuts down.
• Over Temperature Protection: Automatically self-protect when at high temperature – Alarm first, the temperature continuously rises, the red light is on and the inverter shuts down.
• Overload Protection: Automatic self-protection when there is overload – Red LED light is on and the inverter automatically shuts down.

Tips: Why my inverter alarms when plugged in or under load?

• There are serveral reasons regarding the power inverter alarming in such situations:
• The aging of the car lines.
• Poor connection between the cigarette lighter and the battery.
• The connection wire between cigarette lighter and the battery is too thin.
• There is an oxide layer on the contacts of the cigarette lighter, causing poor contact.
• The wires from cigarette lighter to the battery are relatively thin, unable to bring a lot of load.
