How to choose the right Erayak Power inverter
When selecting an inverter, first consider your total wattage requirements. Add up the continuous power draw of all devices you plan to run simultaneously. The surge rating is important for starting motors in tools or appliances. Also think about portability: larger units like the TANK3000 offer high power but weigh over 7 lb, while the TANK400 is only 1.2 lb. Check the connection options – all TANK inverters include AC outlets and USB ports, but the number varies. Finally, confirm your vehicle’s 12V system can handle the input current; larger inverters may require direct battery connection.
What the brand does not state
Erayak Power does not publish warranty terms for its inverters on the product pages or in the policies provided. The brand also does not specify the efficiency rating (e.g., percentage of DC to AC conversion) for any model. Additionally, the exact dimensions of each inverter are not listed, though weights are given. The type of modified sine wave (e.g., total harmonic distortion) is not disclosed. For detailed installation requirements beyond basic input voltage, you may need to contact the brand directly.
Frequently asked questions
What is the difference between continuous power and surge power?
Continuous power is the amount of watts the inverter can supply steadily. Surge power is a higher wattage it can handle for a short time (seconds) when starting devices like refrigerators or pumps. Erayak’s TANK3000, for example, has 3000W continuous and 6000W surge.
Can I use an Erayak inverter to power sensitive electronics like laptops?
Yes, but note that these inverters output modified sine wave, which is suitable for most laptops, phone chargers, and power supplies. For sensitive electronics or sensitive electronics, check compatibility with the brand – pure sine wave is not offered in this lineup.
How do I connect the inverter to my vehicle battery?
Smaller models like the TANK400 and TANK200 plug into a 12V cigarette lighter socket. The larger TANK1000, TANK2000, and TANK3000 require direct battery connection using the included cables or terminals. Follow the brand’s installation instructions for safe setup.
Does the inverter come with a remote control?
Yes, based on the brand’s published specs, the TANK2000 and TANK3000 include a remote on/off control. The TANK1000 and TANK400 do not list a remote in their specifications.
What is the return policy for Erayak inverters?
According to the brand’s refund policy, returns are accepted within 30 days of delivery if items are unused and in original packaging. Return shipping is free. The brand also states that cancellation is possible until the item ships. Check the product listing for any exceptions.
