We’re truly sorry to hear about your experience, and we completely understand how frustrating it must feel when a system doesn’t perform as expected. At Dartello, we take product quality and customer satisfaction very seriously, and we want to clarify a few points to ensure this gets resolved quickly.
Our Maglev 5kW 48V turbines are always shipped according to the voltage specified in the customer’s order. Each unit is tested at the factory and matched with its corresponding 48V MPPT controller. If the turbine is only outputting 12V in strong winds, this may indicate:
*A wiring or connection mismatch (DC polarity or controller input settings).
*Incorrect controller programming for the 48V battery bank.
According to Dartello Ltd’s warranty and support policy, we ask all customers who face performance issues to share with us:
*Order number and invoice copy.
*Photos/videos of the turbine and controller installation.
*Controller settings currently in use.
Once we have these details, our technical team can quickly determine whether this is a configuration issue or if you may have received a mismatched product.
We kindly ask that in cases like this, you contact us directly first, as our support team is always ready to help troubleshoot, check installation settings, and if necessary, arrange a replacement within a 30-day period at no extra cost. This way, we can resolve the matter quickly without unnecessary delays or frustrations.
We want to reassure you and others reading this review that we stand behind every turbine we ship, and we are committed to resolving this matter fairly. Please reach out directly to our support team at contact@dartello.com with your order details so we can assist you immediately.
Best regards,
Customer Support Team
Dartello Ltd.
