I installed a 914i in November last year and this month is really the first time I have been out of a marina for an extended period, so subject to the full force of the weather
. My 914i has been putting in 2 to 3 amps in 10 to 15 knots - and quietly, which is a huge bonus for me as I'm a 33 foot yacht. In the forepeak, we can't hear it, which is great for sleeping. Whilst in Cooktown during a blow, we had 20 knots constantly; and 4 amps. At 25 knots, we had close to 6 amps constantly. At 30 knots constantly, we had 10 to 15 amps. In the gusts over 30 knots, we had 18 to 20 amps. In the gusts around 40 we had more than that, but the amp meter only reads to 20 amps. It was great to have that power and it kept all our stuff going, and the batteries healthy.
After the first night of strong winds, we awoke to find the regulator
dead. We have a HRSi. Both lights were out. We pulled it and replaced it with a spare HRSi we had onboard, and bingo, we were back in business. We have sent the regulator
back under warranty. Two days later, and after a night of constant 30 knot
winds, we woke to find the wind generator
itself braked (turning slowly) even though it was blowing a stink. It was not the thermal cut out, as it's stayed that way. No output.
We're now working with the manufacturer to troubleshoot and remedy the problem. For their part, Marlec's representative has been very helpful and I feel I'm being looked after. It's unfortunate that these breakdowns have happened, because I was happy with the product, but as an offshore
cruiser, now I'm worried about the long term reliability
of the product.
Let's hope I'm just being precious!
