Erayak Power offers a range of modified sine wave inverters from 150W to 3000W continuous, with features like LCD monitoring, USB-C ports, and remote control. Your choice should match your continuous and surge power needs, number of devices, and installation environment.
Power inverters convert DC battery power into AC electricity, allowing you to run household devices from a vehicle, RV, or solar system. Choosing the right inverter depends on your total load, peak startup demands, and how you plan to connect your equipment.
This guide uses Erayak Power’s published product specifications to illustrate key factors.
Who This Guide Is For
This guide is for anyone looking to power AC devices from a 12V battery source—such as in an RV, truck, car, boat, or home solar backup system. Whether you need to charge laptops, run small appliances, or provide emergency power, the criteria below will help you compare inverters using published specs.
Key Criteria to Compare
- Continuous Power vs. Surge Power: Continuous power is the steady load the inverter can handle. Surge (peak) power covers startup demands of motors or compressors. For example, the ERAYAK TANK2000 lists 2000W continuous and 4000W surge.
- Input Voltage: All Erayak inverters in this data use 12V DC input. Ensure your battery system matches.
- Output Voltage: Check whether the inverter outputs 115V or 120V AC. Erayak models vary slightly (e.g., 115V for some, 120V for others).
- Waveform: The listed Erayak inverters are modified sine wave. This is suitable for most electronics but may not be ideal for sensitive electronics (not stated by brand).
- Outlets and Ports: Count the AC outlets, USB-A, and USB-C ports. Models like the TANK150 offer 3 AC outlets plus USB-C/A, while larger units like the TANK3000 include a direct-connect terminal.
- Monitoring and Control: Some Erayak inverters have an LCD display showing battery level, output power, and fault messages. Remote on/off control is included on TANK2000 and TANK3000.
- Weight and Size: Compact models like the TANK400 weigh 1.2 lb, while the TANK3000 weighs 7.2 lb.
Common Mistakes When Choosing an Inverter
- Underestimating Surge Power: Devices like refrigerators or pumps draw 2-3x their running power at startup. Always check the surge rating of the inverter (e.g., 2000W continuous / 4000W surge for the TANK2000).
- Ignoring Ventilation: Inverters generate heat. The TANK2000 and TANK1000 specify a quiet fan; ensure the unit has adequate airflow in your installation.
- Mismatching Input Voltage: All Erayak inverters in this data require 12V DC. Using a different battery voltage will not work.
- Overlooking Cable Gauge: High-power inverters need thick battery cables. The brand does not specify recommended wire size in the data, so consult the product manual.
Questions to Ask the Brand Before Buying
- What is the warranty period for the inverter? (Not stated by Erayak Power in the provided data.)
- Are the AC outlets NEMA 5-15R compatible with my plugs?
- Does the inverter include low-voltage alarm and shutdown to protect the battery?
- Is the unit suitable for outdoor use or does it require a dry location?

Checklist Before You Place an Order
- Confirm the inverter’s continuous and surge ratings exceed the total load of all devices you plan to run simultaneously.
- Verify the input voltage matches your battery system (12V for all Erayak inverters listed).
- Check the number and type of AC outlets and USB ports needed.
- Review the brand’s return policy: returns accepted within 30 days of delivery, items must be unused with original packaging. Return shipping is free.
- Review shipping policy: orders processed same business day (if placed before noon), delivery estimates at checkout. Shipping costs calculated based on destination and weight.
- Note that warranty terms are not stated by the brand; contact Erayak Power directly for warranty information.
Frequently asked questions
What is the difference between continuous and surge power?
Continuous power is the steady wattage an inverter can supply over time. Surge power is the extra capacity to handle startup spikes from motors or compressors. Erayak lists both: for example, the TANK2000 has 2000W continuous and 4000W surge.
Do Erayak inverters come with a warranty?
Warranty terms are not stated in the provided data. Contact Erayak Power directly or check the product listing on their website for warranty details.
Can I return an inverter if I change my mind?
Yes, returns are accepted within 30 days after delivery, provided the item is unused and in original packaging. Return shipping is free. Start a return by logging into your account on the brand’s site.
Are Erayak inverters suitable for sensitive electronics?
All Erayak inverters listed in the data use modified sine wave output. This works for most electronics but may not be ideal for devices with sensitive AC motors or audio equipment. The brand does not provide specific compatibility claims.
How long does shipping take?
Delivery times are estimates shown at checkout. Orders are processed the same business day if placed before noon (excluding holidays). Actual delivery depends on the carrier and destination.
