Using Multiple AC Devices

When more than one device is connected, start the devices one at a time.

This reduces the possibility of simultaneous startup surges causing an inverter overload.

The combined continuous AC load must remain within the 1000W limit.

Understanding Startup Power

Some electrical appliances require additional power when starting.

These include devices with motors, such as fans and similar equipment.

The generator can provide a momentary surge of up to 2000W for less than one-tenth of a second.

However, some equipment rated below 1000W may still draw too much startup power and trigger an overload shutdown.

AC Overload Protection

The inverter includes an automatic shutdown function.

When excessive power demand is detected:

1. The Warning icon flashes.
2. The inverter automatically shuts down.
3. The shutdown protects the inverter from overload-related damage.

The manufacturer recommends testing individual devices to determine whether they can operate within the inverter’s power limits.

AC Extension Cord Requirements

The manual recommends the following extension cord specifications for the inverter output.

Important AC Outlet Precautions

Warning: The 110V AC outputs can cause electric shock or electrocution.

• Do not connect an external AC power supply to the generator’s output outlets.
• Do not plug the generator’s own AC charging cord into its output outlets.
• Do not connect appliances that require more than 1000W of continuous power.
• Test equipment to confirm compatibility with the inverter.
• Start connected appliances one at a time.
• Recharge the internal battery when its capacity falls below 40%.

Extended AC operation can cause excessive battery discharge.
