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 the power inverter alarms when plugged to the car cigarette lighter, or the inverter sounds an alarm with running a load？

There are serveral reasons regarding the power inverter alarming in such situations:

1. The aging of the car lines.

2. Poor connection between the cigarette lighter and the battery.

3. The connection wire between cigarette lighter and the battery is too thin.

4. There is an oxide layer on the contacts of the cigarette lighter, causing poor contact.

5. The wires from cigarette lighter to the battery are relatively thin, unable to bring a lot of load.
