Important Compatibility Note: The ERAYAK DSU-2000 provides up to 2000W continuous power / 4000W peak power from a compatible 12V DC battery system. It produces pure sine wave AC output with THD below 5% at normal load. Always verify connected-device voltage, running wattage, startup surge, and installation requirements before use.
Simple Care. Reliable Power.
Keeping your ERAYAK DSU-2000 in good operating condition mainly involves maintaining clear ventilation, keeping DC connections tight, removing dust from the cooling system, monitoring operating conditions, and keeping liquids and conductive materials away from the inverter.
| Maintenance Item | When to Check | What to Do |
|---|---|---|
| Fan Vents | Regularly and before heavy use | Make sure all fan vents and ventilation openings are unobstructed. |
| Cooling Fan Area | As needed | Use a vacuum cleaner to remove accumulated dust from the fan area. |
| DC Input Terminals | Before use | Check that the positive (+) and negative (-) DC input terminal screws are firm and tight. |
| Battery Wiring | Before use and after installation changes | Inspect wiring for correct polarity, secure connections, adequate cable size, and visible damage. |
| Connected Load | Before and during use | Keep total continuous power within 2000W. For longer inverter life, the user guide recommends normal load within approximately 85% of rated output. |
| LCD & Fault Codes | During use | Monitor input voltage, load power, output frequency, output current, battery power, and fault codes for abnormal operating conditions. |
| Exterior Cleaning | As needed | Use a soft, dry cloth. If heavily soiled, use a neutral, non-abrasive detergent. Do not use alcohol- or ammonia-based cleaning solutions. |
| Physical Condition | Before use | Inspect the housing, terminals, wiring, fan area, outlets, and connections for damage or abnormal condition. |
| Storage & Environment | When not in use | Keep the inverter dry, well ventilated, and protected from water, excessive humidity, combustible gases, conductive dust, and foreign metal objects. |
Service Note: The DSU-2000 does not require engine-style scheduled maintenance. Regular inspection of the DC terminals, wiring, ventilation system, fan area, connected load, and operating indicators is the primary maintenance requirement.
1. Cooling & Ventilation — Keep Airflow Clear
Make sure the front, rear, and bottom ventilation openings are not blocked. The DSU-2000 must be installed in a well-ventilated location so the cooling system can operate properly.
The mounting surface should be flat. An uneven mounting surface may affect cooling-fan heat dissipation.
2. Fan Area — Remove Dust Regularly
Check the cooling-fan area periodically for accumulated dust. Use a vacuum cleaner to remove dust from the fan and ventilation area without opening the inverter housing.
3. DC Connections — Keep Terminals Tight
Check that the screws on the positive (+) and negative (-) DC input terminals remain firm and tight. Loose DC connections can cause overheating and create a potential electrical or fire hazard.
Use appropriately sized, high-quality copper wiring and keep cable length suitable for the installation.
4. Load Management — Avoid Continuous Overloading
The DSU-2000 provides 2000W continuous power and up to 4000W peak power.
For longer inverter service life, the user guide recommends keeping normal connected load within approximately 85% of rated output power.
If overload protection activates, reduce the connected load to within the rated power range before restarting or allowing the inverter to recover.
5. Temperature — Maintain Proper Operating Conditions
The user guide identifies -15°C to 25°C as the recommended operating-temperature range for best performance.
The temperature-controlled cooling fan starts at approximately 65°C, while over-temperature protection activates when internal temperature exceeds approximately 96°C.
If an over-temperature shutdown occurs, stop using the inverter and allow it to cool before resuming operation.
6. LCD Fault Codes — Check Before Restarting
- E0: Low Voltage
- E1: Over Voltage
- E2: Over Temperature
- E3: Overload
- E4: Output Short Circuit
Identify and correct the cause of the fault before restarting the inverter.
7. Cleaning — Use the Correct Materials
Use a soft, dry cloth to clean the inverter housing and front panel. If the surface is heavily soiled, use a neutral and non-abrasive detergent.
Do not use alcohol- or ammonia-based cleaning solutions, and prevent liquids or metal objects from entering the inverter.
8. Service & Repair — Do Not Disassemble
Do not open or disassemble the DSU-2000. Attempting internal repair may damage the inverter and can create a risk of electric shock or fire.
If internal service is required, contact ERAYAK Support or qualified professional service personnel.
Important Reminder: Keep the DSU-2000 well ventilated, maintain firm DC connections, use appropriately sized copper wiring, keep normal load within the recommended operating range, remove dust from the fan area when needed, keep liquids and metal objects away from the inverter, and never open or disassemble the unit for routine maintenance.

Service Note: The DSU-2000 does not require engine-style scheduled maintenance. Regular inspection of the DC terminals, wiring, ventilation system, fan area, connected load, and operating indicators is the primary maintenance requirement.
1. Cooling & Ventilation — Keep Airflow Clear
Make sure the front, rear, and bottom ventilation openings are not blocked. The DSU-2000 must be installed in a well-ventilated location so the cooling system can operate properly.
The mounting surface should be flat. An uneven mounting surface may affect cooling-fan heat dissipation.
2. Fan Area — Remove Dust Regularly
Check the cooling-fan area periodically for accumulated dust. Use a vacuum cleaner to remove dust from the fan and ventilation area without opening the inverter housing.
3. DC Connections — Keep Terminals Tight
Check that the screws on the positive (+) and negative (-) DC input terminals remain firm and tight. Loose DC connections can cause overheating and create a potential electrical or fire hazard.
Use appropriately sized, high-quality copper wiring and keep cable length suitable for the installation.
4. Load Management — Avoid Continuous Overloading
The DSU-2000 provides 2000W continuous power and up to 4000W peak power.
For longer inverter service life, the user guide recommends keeping normal connected load within approximately 85% of rated output power.
If overload protection activates, reduce the connected load to within the rated power range before restarting or allowing the inverter to recover.
5. Temperature — Maintain Proper Operating Conditions
The user guide identifies -15°C to 25°C as the recommended operating-temperature range for best performance.
The temperature-controlled cooling fan starts at approximately 65°C, while over-temperature protection activates when internal temperature exceeds approximately 96°C.
If an over-temperature shutdown occurs, stop using the inverter and allow it to cool before resuming operation.
6. LCD Fault Codes — Check Before Restarting
- E0: Low Voltage
- E1: Over Voltage
- E2: Over Temperature
- E3: Overload
- E4: Output Short Circuit
Identify and correct the cause of the fault before restarting the inverter.
7. Cleaning — Use the Correct Materials
Use a soft, dry cloth to clean the inverter housing and front panel. If the surface is heavily soiled, use a neutral and non-abrasive detergent.
Do not use alcohol- or ammonia-based cleaning solutions, and prevent liquids or metal objects from entering the inverter.
8. Service & Repair — Do Not Disassemble
Do not open or disassemble the DSU-2000. Attempting internal repair may damage the inverter and can create a risk of electric shock or fire.
If internal service is required, contact ERAYAK Support or qualified professional service personnel.
Important Reminder: Keep the DSU-2000 well ventilated, maintain firm DC connections, use appropriately sized copper wiring, keep normal load within the recommended operating range, remove dust from the fan area when needed, keep liquids and metal objects away from the inverter, and never open or disassemble the unit for routine maintenance.
