ACCESSORY LIST

The following accessories are included or recommended:

• MC4 to Anderson Cable
• AC Charger
• Car Charger
• User Manual
• Cable Storage Bag

It is recommended to use 120W/200W/300W/400W/600W Solar Panels (not included).

GENERAL SPECIFICATIONS

SOLAR PANEL CHARGING

Do not charge the unit via a solar panel that operates voltage exceeding 60V. Support 600W max solar input (solar panels not included); the charging time depends on the solar light intensity. If the solar panels produce 600 watts of power, then it can be fully charged within 2-3 hours.

Connecting Pattern 1:

Connect the device to the Anderson port using the MC4 to Anderson cable. Connect the solar panel to the MC4 connector.

Connecting Pattern 2:

Connect multiple solar panels in series or parallel to the MC4 connectors, then use the MC4 to Anderson cable to connect to the device's Anderson port.

AC CHARGER CHARGING

Please use the provided AC charger. It will be fully charged in about 125 minutes with a 600W AC input and in about 75 minutes with a 1200W AC input. Connect the AC charger to the device's AC input port and a wall socket using the AC charging cable.

CAR CHARGER CHARGING

Use the provided 12V car charger. Charging time for 12V car charger is about 9-10 hours, and for 24V car charger is about 4.5-5.5 hours. Car charging is typically low power (90-120W). For a quicker charge, use the AC adapter. Connect the car charger to the device's Anderson port and the car's 12V/24V socket using the car charging cable.

EPS MODE

EPS Function: This product has a bypass mode, allowing direct output from the AC without passing through the battery. In EPS mode, if the mains AC input is cut off due to a power outage, the product automatically switches to the internal battery within 20ms to ensure continuous AC output.

EPS Connections: Connect the product between the wall socket and the electrical appliances. Ensure the product is in the ON state. When appliances are turned on, they will use AC power from the grid. If the power grid fails, the product automatically switches to its internal battery.

Note: In EPS mode, when charging and discharging simultaneously: AC is straight-through output if charging power is less than 1200W. AC charging + AC discharge total power should not exceed 1920W.

OPERATING INSTRUCTIONS

Power Output Attention: Press the output switch to select the desired outlet type. The corresponding button must be pressed to activate the port. The LCD display will turn on and show charging output information. The LCD screen will automatically turn off when no output is activated.

Cooling Fan: The internal cooling fan ensures the product operates within the proper temperature range. The fan turns on automatically under high output load, during discharging and charging, or when the AC circuit is activated to maintain normal operation.

Fan on condition: The cell temperature is greater than 55°C±5°C, the AC output power is greater than 1000W, or the inverter radiator temperature is greater than 90°C±5°C.

Overload Protection (Rated Power Mode):

• Rated power 2200W, Load ≤ 2200W for long-term operation.
• 2.45KW < load ≤ 2.88KW: Enter overload protection after 5-10 seconds.
• 2.88KW < load ≤ 3.6KW: Enter overload protection after 1-5 seconds.
• load > 3.6KW: Immediately enter overload protection.

After overload release, press the button to restore normal output.

Constant Power Mode:

• Compatible with 99% of resistive equipment with load < 2000W.
• Does not support constant power when AC charging.
• When Load > 2.0KW, enter constant power 2000±50W.
• When Output voltage=90V±5V and power > 2100W, shutdown occurs after 5-10 seconds.

Power Saving Sleep Mode (ECO Mode): When output power is less than 5W, the device enters hibernation after more than 8 hours. It can be awakened by charging or pressing any button. When not in use, press the switch button to turn off the output.

FAULT RESOLUTION

Refer to the table below for fault codes, types, and release operations:

Please contact GRECELL after-sales service if the fault is not resolved.

TROUBLE SHOOTING

The device does not discharge:

1. Check if the connecting wire is inserted correctly.
2. Check if the total output power exceeds the rated output power.
3. Check if the equipment's temperature is too high.

The device is not charging:

1. Confirm that the AC socket and AC charging cable are fully inserted into the AC input terminal.
