So, of all the new technologies we’ve gotten to know and the new battery chemistry and the new…well…everything propulsion and steering that isn’t our sailing rig, the only one to cause us enduring frustration has been the 48v Rutland 1200 windcharger (the British way of saying wind generator, it seems).
They fairly recently got on board the high voltage train with a 48v version of the 12v wind generator we already own (see last year’s installation). They only about a year ago got some kind of support for the LiFePO4 batteries that are powering modern electric sailboats.
And their shit is not working.
We paid extra for a standard-phone-plug-to-USB cable and PC app that was supposed to let us change the charge parameters so that they’d work with our lithium phosphate battery pack. Instead, this program let me change some parameters and save the changes…it said the controller had received them…but when I disconnected and reconnected, it had all gone back to the defaults.
Why is this a problem? Well, their “return to bulk” setting (also not standard terminology as far as I can tell) is so low that we would have to nearly kill the battery before the controller would take the wind generator off standby.
Now we’re dealing with a company that’s about 3000 miles away and not jumping to fix this problem for us. We’re heading their direction but, believe me, carrying this broken system back to them for fixing is not exactly Plan A. Here’s hoping they fix us up in the next couple-few days so that we can keep our new electric motor running in the fashion to which we’d like to become accustomed.
