The LCD display provides real-time monitoring of the inverter's status:

1. Inverter working status (Normal/Fault)
2. Working temperature inside the inverter
3. Battery voltage and capacity
4. AC1 120V voltage and amperage
5. AC2 120V voltage and amperage
6. Output of 240V and frequency (60Hz)

5. Installation

5.1. DC Battery Connection (24V System)

The inverter requires a 24V DC battery system. For a 24V system using two 12V batteries, connect them in series (positive of one battery to negative of the other). Ensure the battery bank is properly sized for your power needs.

1. Connect Negative Cable First: After connecting the black cable(s) to the battery's negative terminal, connect the other end of the black cable(s) to the inverter's negative terminal.
2. Contact Spark-Proof Terminal: Briefly touch the spark-proof terminal with the positive cable for 3-5 seconds to discharge any residual capacitance.
3. Connect Positive Cable: Connect the red cable(s) to the battery's positive terminal, then connect the other end to the inverter's positive terminal.

Important: Use all provided cables. For 4 cables, use 2 black for negative and 2 red for positive. Ensure all connections are tight to maintain stable current flow.

5.2. AC Output Wiring

The inverter supports both 120V and 240V AC output. You can use the standard 120V outlets or the hardwire terminals for direct connection to your electrical panel.

For hardwire connections:

• L1 to Hot 1
• L2 to Hot 2
• N to Neutral
• G to Ground

The inverter can run 120V and 240V appliances simultaneously. Ensure the total amperage does not exceed 25A for the connection.

6. Operation

Once the inverter is properly installed and connected to the battery bank, press the power switch on the front panel to turn it on. The LCD display will illuminate, showing the current operational status.

6.1. Connecting Appliances

Plug your 120V AC appliances into the standard outlets or connect 120V/240V appliances to the hardwire terminals. Ensure the total wattage of connected appliances does not exceed the inverter's continuous power rating of 10000W.

The inverter is compatible with a wide range of appliances, including those for home, cabin, mobile business, RV, trailer, semi-truck, and boat use. It supports AGM, gel, flooded, lead-acid, and lithium-ion batteries.

7. Protection Features

The WZRELB inverter is equipped with multiple protection features to ensure safe and reliable operation:

• Temperature-Controlled Cooling Fan: Activates automatically to prevent overheating.
• Low Voltage Alarm/Shutdown: Protects batteries from over-discharge.
• High Voltage Alarm/Shutdown: Protects the inverter and connected devices from over-voltage.
• Overload Protection: Shuts down if connected load exceeds capacity.
• Short Circuit Protection: Prevents damage from short circuits.
• Over Temperature Protection: Shuts down if internal temperature becomes too high.
• Internally Fused: Provides additional circuit protection.
• Battery Reverse Polarity Protection: Guards against incorrect battery connections.
