Frequently-Asked Questions
Q: What can a 400 watt wind turbine power?
A: With the Automaxx 400W wind turbine, you can power a range of everyday electrical devices and appliances. It’s perfect for lighting up your outdoor spaces with energy efficient LED lights, charging your electronic devices like smartphones, tablets and laptops. However the power output from a wind turbine depends on the wind speed, battery bank system and inverter. With a larger capacity battery bank and inverter you would be able to power more electric appliances.
Q: Do 400 watt wind turbines put out AC or DC?
A: The AC power generated by Automaxx’s 400W wind turbine undergoes conversions to DC power using the integrated charge controller. This DC power is subsequently stored in a battery bank for future utilization.
Q: How many amps does a 400W wind turbine produce?
A: The maximum output of Automaxx 400W wind turbines is 33 amps. The amplitude of amperage generated is contingent upon several variables, including wind velocity, wire gauge, wire length and battery capacity.
Q: How does a 400W wind turbine compare to other sizes in terms of efficiency and performance?
A: Our 400W wind turbines stand out for their impressive efficiency and performance. While larger turbines may offer higher power output, our compact 400W turbines are specifically engineered to excel in moderate wind conditions. They strike the perfect balance, providing optimal energy production in areas with consistent and moderate wind speeds.
Q: What is the expected lifespan of a 400W wind turbine?
A: When it comes to longevity, our 400W wind turbines are built to last. With rigorous quality control measures and durable materials, our turbines boast an average lifespan of 20 years or more. This extended lifespan ensures you enjoy years of reliable and cost-effective renewable energy generation.
Q: What are the maintenance requirements for a 400W wind turbine?
A: We understand the importance of hassle-free ownership, which is why our 400W wind turbines require minimal maintenance. Our turbines feature robust components and innovative design elements that reduce the need for frequent servicing. Routine inspections and occasional lubrication are all that’s needed to keep your turbine operating at peak efficiency.
Q: How much space is needed to install a 400W wind turbine?
A: Our 400W wind turbines are designed with compactness in mind, making them ideal for installations where space is a consideration. With their small footprint and efficient design, our turbines can be easily integrated into various settings, including residential properties, farms, and off-grid applications.
From day one when I ordered a eahora romeo 2 2025 off grid lux has been in constant contact . From shipping the bike to after care I haven't had issues at all . They even called me to check on an issue I had and I actually spoke to a person , who was great by the way . Customer service has fallen to the big internet conglomerates but I didn't feel that way with the purchase , they have really tried to take care of me and answered every question I've asked , even ones that are stated on the site . Im happy I went with them .I hope I can purchase other stuff in the future here .
The products won't be flawless but their customer service is . Thanks again Greg
Mototec Raider, paid for assembly, arrived with flat tire, dangling cracked headlight, scratched and scuffed. Customer service very responsive and able to resolve issues and make it right. They answer the phone and actually talk to you!

I bought an extra battery to increase my ebike range. Of all the sites I looked at, I was sure this one would fit my battery mount because it was labeled correctly. Not true of other sites. They shipped quickly and the battery was packed properly. Good business--would easily buy from this site again.
The whole process from ordering through receipt with Off Grid Lux was seamless. They responded quickly to our initial questions and helped us decide on the best product to suit our needs. There was a small hiccup with the shipment delivery (the fault of the carrier) and Odd Grid Lux contacted the carrier immediately and had our issue resolved. We researched many vendors before deciding on Off Grid Lux and their pricing and customer service cannot be beat.
Was a little nervous at first but Christian was GREAT. Company honored everything stated, customer service top notch and Fantastic communication. Need to give them a try to see how they can service and help you!
I bought this battery to replace my battery that died in my Ecotric 20810 (the fat tire one from around 2019 timeframe). Went on a 2+ hour ride and still had plenty of juice to spare. Wish it was cheaper but....it's a big battery and that's the retail price I guess.
Ordered four inverters for a customer whose solar system was damaged by a utility surge. OffGridLux advertised these inverters at $2500. Upon ordering the inverters I was assured they were in stock and would be delivered. The next day I received a refund and the price of the inverters went up from $2500 to $3100 on the OffGridLux website. Chris in customer service explained the inverters were a new product and the $2500 price was added by mistake and the real price was $3100. He also told me his warehouse made a mistake they only had 2 of the 4 available. After expressing my frustration at the situation since the customer was already quoted the lower price, Chris worked out a deal and gave us the inverters at cost to OffGridLux for $2850 instead of $3100. Chris promptly adjusted the charge and made sure the 2 inverters were shipped out asap. As a small business owner I understand how small mistakes can be costly and sometimes the little things are the biggest problem. In good fashion Chris represented OffGridLux and my interests by communicating and figuring out an amicable solution for all parties involved. Thank you again Chris. You sir a true asset to your company.

This place is one of the best companies I've ever purchased from they have excellent customer service fast shipping and answer all your questions in a timely manner i love my bike i had a small problem which they quickly addressed i have been extremely impressed with how helpful they have been i highly recommend this company I promise you won't regret it
