Inverter Installation

Ensure sufficient space and choose a location meeting the following requirements:

1. Water should not access the inverter.
2. Ambient temperature should be between 32~104°F (0~40°C), with a preferred range of 50-77°F (10-25°C).
3. Do not mount the inverter upside down.
4. Allow 12 inches (30 cm) of space around the inverter for ventilation.
5. Do not install in environments with high dust, sawdust, or other particles that could increase internal temperature.
6. Electrical arcing or sparks may occur when connecting to the battery. Keep combustible materials (gasoline, alcohol) away.
7. Mount the inverter on a stable surface to prevent bouncing and potential damage. Use all four mounting screws for stability. Ensure the location can support the inverter's weight.

Remote Controller Installation

1. Remove the back holder of the remote control.
2. Fix the back holder using the two provided screws.
3. Connect one side of the wire to the remote controller before attaching the back holder.
4. Attach the remote to the back holder.
5. Connect the other side of the cable between the remote and the inverter.

Note:

• The remote is designed for dash mounting; a hole may be required for flush fitting.
• Connect the remote cable to both the inverter and remote before fixing the holder.
• The product can be used without the remote control box, utilizing the manual power switch.

Battery

The battery supplies the DC input voltage. Ensure the battery voltage matches the inverter's rated input voltage. Exceeding this range can cause overload or damage. The battery must supply sufficient current for the load (equipment's amp or watt rating). A small capacity battery may not power large equipment, leading to under-voltage protection.

Calculating Load/Amps: Divide the equipment's wattage by the battery voltage. For example, for 1000W equipment on a 12V battery: 1000W / 12V = 83.3 Amps. Add 10% for efficiency loss: 83.3 * 1.10% = 91.6 Amps per hour. To find wattage if only amps are known, multiply AC amps by AC voltage (e.g., 8 AC amps * 120 Volts AC = 960 watts). Remember, equipment with motors may require 3-5 times their running wattage for startup (e.g., 960 watts * 3 = 2880 watts).

Battery Operating Time: Calculated as: (Battery Capacity) / (Load Amps) * 1.10%. For a 12V, 200Ah battery with a 1000W load (91.6 Amps): 200Ah / 91.6 Amps = 2.18 hours. It is not recommended to fully deplete deep cycle batteries; aim for 50% capacity.

Battery Connection Table

Notice:

• The table is a reference; two thin parallel wires can replace a thick wire if total cross-sectional area meets requirements.
• In high current, input DC wires may cause voltage drop. Operating voltage should be based on terminal values. If drop is too large, increase wire cross-section or reduce lead length (recommended < 1m).
• Connect the cathode wire (black) to the cathode terminal and the anode wire (red) to the anode terminal on the inverter.

Battery Connection Warnings

1. Wear eye protection and work clothes to protect against acid and corrosive materials.
2. Have water and soap ready for immediate skin cleaning. For eye contact, flush with cold water and seek medical attention.
3. Do not place combustible materials near the installation area due to potential sparks.
4. Ensure good ventilation. Batteries can produce flammable gas. Keep them separate from the inverter.
5. Secure input DC wires to prevent voltage reduction or wire overheating.
6. Reversing polarity or short-circuiting will burn the fuse or permanently damage internal elements.
7. Remove metal accessories (rings, watches) during installation to avoid short circuits.
8. While over-voltage protection exists, excessively high input voltage can still damage the inverter.

AC Appliance Connection

Plug AC appliance power cords directly into the inverter's output AC receptacles.

Warnings:

• Ensure inverter and appliance power switches are OFF before connecting.
• Check power cords for damage; replace if necessary.
• Each outlet has a rated current. Do not exceed this limit to prevent overheating and electric shock.

Maximum Output Power per Socket

Connection of big load: For appliances exceeding AC socket limits, connect to Hard wire Terminals (if available). Ensure the inverter's ground terminal is connected to the appliance's ground terminal.
