Warranty Note: Warranty service is subject to the applicable ERAYAK warranty terms, proof of purchase, proper operation and maintenance, technical verification, and applicable exclusions. Misuse, incorrect polarity, excessive load, blocked ventilation, improper direct-connect wiring, moisture exposure, unauthorized modification or repair, physical damage, or other operation outside the TANK3000 user guide may affect warranty eligibility.

Shipping Note: Delivery times are estimates and may vary based on inventory availability, destination, carrier conditions, weather, holidays, and other logistics factors. For urgent, remote-area, or special delivery requests, contact ERAYAK Support before placing your order.

Performance Note: Actual operation depends on battery condition, connected load, startup demand, input voltage, temperature, ventilation, connection method, and device compatibility. The TANK3000 produces modified sine wave AC output, so always verify the connected device's voltage, wattage, startup requirements, and waveform compatibility before use.

1. 3000W Continuous Power

The TANK3000 provides up to 3000W of continuous AC power for compatible 12V battery-powered applications.

2. Low No-Load Power Draw

With a no-load power draw of less than 0.45A DC, the TANK3000 helps limit unnecessary battery consumption when the inverter is powered on without a significant connected AC load.

3. Real-Time Power Monitoring

The LCD display lets you monitor battery level, battery input voltage, and AC output power, helping you understand available battery capacity and connected power demand during use.

4. Low-Battery Protection

A low-battery alarm activates at 10.5V DC, while low-battery shutdown occurs at 9.5V DC to help reduce excessive battery discharge.

5. Multiple AC Output Options

The TANK3000 provides 120V/20A and 115V/15A AC outlets together with a 110V direct-connect terminal, giving compatible applications multiple AC connection options.

6. Remote Power Control

The included remote on/off switch allows the inverter to be controlled from a more convenient location when the main unit is positioned away from the operator.

7. Disconnect When Not in Use

The user guide recommends disconnecting the inverter when it is not in use to help prevent accidental battery discharge. The USB ports remain active even when the inverter is switched off.

1. Low-Battery Protection

The TANK3000 provides a low-battery alarm at 10.5V DC and shuts down at 9.5V DC to help protect the connected battery from excessive discharge.

2. High-Voltage Protection

The inverter shuts down if battery voltage rises above its safe operating range. The specified high-voltage shutdown point is 15.5V DC.

3. Over-Temperature Protection

The TANK3000 monitors operating temperature and automatically shuts down if the inverter exceeds its safe temperature threshold.

4. Temperature-Controlled Cooling

The built-in temperature-controlled cooling system operates as needed to help manage heat and support stable operation under load.

5. Overload & Short-Circuit Protection

The inverter shuts down when connected power demand exceeds its rated output or when a short circuit is detected.

6. AC Outlet Reset Protection

Each reset-equipped AC outlet uses a manual reset button that functions as a built-in circuit breaker. If an overload or short circuit occurs on the connected device, the affected outlet can shut off to help protect the system.

7. LCD Fault Monitoring

The LCD display provides fault information and warning messages when abnormal operating conditions are detected, helping users identify the issue and take corrective action.

8. Remote On / Off Control

The included remote on/off switch provides convenient control when the inverter is positioned away from the main operating area.

Important Compatibility Note: The ERAYAK TANK3000 provides up to 3000W continuous power according to the current user guide and is designed for use with a compatible 12V battery. It produces modified sine wave AC output. Always verify connected-device voltage, current, running wattage, startup requirements, and waveform compatibility before use.

Simple Care. Reliable Power.

Keeping your ERAYAK TANK3000 in good operating condition is straightforward. Routine maintenance mainly involves checking battery and AC connections, monitoring battery voltage and connected load, keeping the cooling system clear, and inspecting the remote control, direct-connect terminal, and AC outlet reset system when needed.

Service Note: The TANK3000 does not require engine-style scheduled maintenance. Regular inspection of battery connections, ventilation, AC connections, remote-control connection, connected load, outlet reset system, and physical condition is the primary maintenance requirement.

1. Battery Connections — Check Before Use

Inspect the terminal input cables and threaded positive (+) and negative (-) terminals before use. Make sure all battery connections are secure and correctly polarized before turning on the inverter.

2. Battery Voltage — Monitor Operating Condition

The TANK3000 provides a low-battery alarm at 10.5V DC and shuts down at 9.5V DC.

If a low-voltage shutdown occurs, recharge or replace the battery and make sure the inverter is connected to a fully charged compatible 12V battery.

The inverter also provides high-voltage shutdown at 15.5V DC. Disconnect any charging source that causes battery voltage to exceed the safe operating range.

3. Load Management — Stay Within Rated Power

The current TANK3000 user guide specifies 3000W continuous power.

If an overload or short-circuit shutdown occurs, disconnect high-power devices and verify that the total connected demand is within the inverter's rated output.

To manually reset the inverter after correcting an overload or short-circuit condition, press and hold the power button for approximately 2 seconds to turn it off, then turn it back on.

4. AC Outlet Reset Buttons — Reset the Affected Outlet

The TANK3000 AC outlets include manual reset buttons that function as built-in circuit breakers.

If an overload or short circuit causes an outlet reset button to pop out, disconnect the connected device, wait a few seconds, and press the reset button to restore operation after the fault has been corrected.

Other AC outlets can continue to function normally when only one outlet has been affected.

5. Cooling & Ventilation — Keep Airflow Clear

Do not cover or block ventilation openings. Allow at least 3 inches (7.5 cm) of clearance around the TANK3000 for proper airflow.

If an over-temperature shutdown occurs, turn off connected devices and allow the inverter to cool for at least 10 minutes. Make sure the cooling system is not blocked and that air can circulate freely before restarting.

6. Direct-Connect AC Terminal — Inspect Wiring Carefully

The TANK3000 includes a 110V direct-connect AC terminal with Line (L), Neutral (N), and Ground (GN) connections.

Before use, make sure each conductor is securely fastened and that no loose copper strands are exposed outside the terminal block.

7. Remote Control — Check Connection When Needed

The TANK3000 includes a remote on/off switch. If remote operation becomes unavailable, inspect the remote switch and its connection to the inverter before further troubleshooting.

8. Battery Discharge — Disconnect When Not in Use

Disconnect the TANK3000 from the battery when it is not in use to help prevent accidental battery discharge.

The user guide notes that the USB ports remain active even when the inverter itself is switched off.

9. Cleaning & Storage — Keep It Dry

Disconnect the inverter from the battery before cleaning, inspection, or storage.

• Keep the inverter away from moisture and conductive dust.
• Do not cover or obstruct the ventilation openings.
• Keep the unit away from direct sunlight and heat sources.
• Do not operate near propane, gasoline, or other flammable gases or fumes.
• Store the TANK3000 in a dry indoor environment.
• Keep the inverter away from children.

10. Battery Safety — Use Proper Precautions

• Follow the battery manufacturer's safety instructions.
• Wear protective gloves and eyewear during installation or maintenance.
• Never smoke or expose batteries to open flames or sparks.
• Do not drop metal tools or conductive objects near the battery terminals.
• Keep soap and water nearby when working around lead-acid batteries.

Important Reminder: Use the TANK3000 with a compatible 12V battery, keep connected demand within the rated output specified in the current user guide, maintain at least 3 inches of ventilation clearance, monitor battery voltage, use the AC outlet reset buttons when required, follow the direct-connect AC terminal instructions, and disconnect the inverter from the battery when it is not in use.
