This is my first post since joining the forum. Hope someone out there can offer some advice as I am about at my wits end with the solar panels
on my boat. Although considering I may be a half-wit, perhaps I haven't gone that far. Anyway, I recently acquired a boat equipped with 2 Kyocera
120 watt panels
, wired thru a Pro Star PS-30 controller. There is also a Kiss wind generator
(no controller) and a Link 20 monitor
. House bank is 2 Lifeline 8D's AGMs. The most obvious problem currently is that the Pro Star does not show an amps out on the display, nor does the Link 20 ever show any amps in when the solar
should definitely be producing. The voltage reading on the controller mirrors what the Link 20 shows for battery
voltage, and the battery
status lights respond to decreasing battery voltage. With the boat anchored in the Virgin Islands
(plenty of sunlight) and no load whatsoever, the house bank will slowly self-discharge (as would be expected), making me quite certain that the solar
is not producing. Here are some test results; open circuit reading from the solar array: 17-19 volts. Open circuit reading on the battery leads to the controller: equals battery voltage as per Link 20. Amp reading across the leads from the solar array: 6 - 6.5 amps on a sunny day. The controller was replaced once by Morningstar who reported that a bench test of the returned unit showed no problem. At there suggestion, I isolated the 2 panels
and checked readings. The controller showed no change in its readings with either panel attached independently. Voltage and amp readings on the panels where identical.
All this seems to point towards a bad controller. The only thing I haven't tried is disconnecting one battery lead at the controller and putting my ammeter in series to see if there is any meaningful draw.
So, does anyone have a suggestion of where I might look next?
