So what could have possibly of changed ???Re: GP-PWM-30 OVER VOLTAGE ERRORUPDATE: New controller arrived and, not the problem. So to sum up, I STILL have the solar panels over voltage issue AND for some reason the input power to the controller is lower than the voltage supplied. I must say I AM NO ELECTRICIAN, but know enuff to be dangerous. Batteries and fully charged now, been plugged in to shore power all week, so WTF is going on with this solar system?? As far as I know, nothing has changed, Everything worked fine before and then all of a sudden, noticed the controller displaying a OV fault. The best I can tell everything "LOOKS" as it should. I don't see anything obvious, but that is the problem with electrical work, everything can look fine but.............Re: GP-PWM-30 OVER VOLTAGE ERROR BFL13 wrote: Two different issues apparently; 1. battery voltage 12.19 should be that at the controller's BATT terminals. No idea why it is 7 volts instead of 12.2v 2. ARRAY terminals on controller should be close to that 12.2 too, where a PWM controller just passes through battery voltage until its high voltage set point is reached. It then "controls" to keep that voltage from going higher. Typical high set point 14.6v You have 22 volts at the ARRAY side, indicating that the panel voltage is reading typical OC voltage for a "12v" panel so the panel wiring to the controller is shorted. Unless you shorted it with the meter and got OCV, which is how you measure OCV. Meanwhile your battery is going down in state of charge, now as low as it ought to go (half way) so you need to plug in a battery charger (or use the converter with shore power or gen) while the solar gets sorted out. This is what I was afraid of, something else may be amiss, just not sure what or how in changed or shorted. My have to take it in to be looked at, just NOT what I wanted to do. I did order a new controller, will try that first and see it that cures the problem, if not, take it to the dealer and let them sort it out. Plugged in for now to get the batt's back up in charge........Re: GP-PWM-30 OVER VOLTAGE ERROR time2roll wrote: ???? converter output, battery, controller output terminals should all be within half a volt. Fix the wiring issues. Well that is the issue, not sure it is a wiring issue/problem, thinking and hoping that it is the controller And if it is wiring, not sure how it changed, everything worked fine before. That is why I am so confused about this issue. Secondly, I admit, when it comes to electrical, I am in over my head, especially on this Motorhome. I am mechanically inclined and try to do things myself, saves money and don't trust dealers. But trying to make head and tails of all the components and electrical wiring runs makes my head spin. Not sure how it was all wired and where the wires are ran to chase down the problem. Was hoping it was a simple problem, but as the layer are pealed back, maybe not so easy.Re: GP-PWM-30 OVER VOLTAGE ERROR BFL13 wrote: You need to use your multimeter while the controller is flashing (that is important! not when it is not flashing), and tell us exactly what the voltage is - right at the batteries, 12.19 - right at the converter's output terminals, not at the converter but at the controllers terminals 22.2 - right at the controller's battery wire terminals. 7.66 Not using some display voltages--the independent hand held multimeter's voltage readings. Also whether you are plugged in so you have converter (or inverter/charger?) DC voltage in the mix. No shore power and no generator running It is normal to have solar as well as converter DC to the house batteries at the same time while on shore power or generator. as far as the converter, only terminals i seen was I guess the input and that was 12.19 also....... so not really sureRe: GP-PWM-30 OVER VOLTAGE ERRORUpdate: So, went out this morning and cked on everything, No bueno..... right back where I started. So rounded up enuff cardboard and materials to cover panels, went thru the hard reset again and just uncovered 1 panel and same results, over voltage... So my question is..... Is it a bad controller or something else in within the solar/power/batt system ????Re: GP-PWM-30 OVER VOLTAGE ERRORSo, just wanted to add that I disconnected wires, let the controller sit for more than an hour and reconnected every thing...... BUT, it is dark out side, so to really know if it worked, I will have to wait for tomorrow and the sun to come up. HOWEVER, Playing around with the controller........ Conditions: Dark, Gennerator running..... It is also worth noting, I have 4 batteries (6v), and 3 panels (not sure of the specs).... The battery voltage doesn't match that of the motorhomes systems control panel, 2-3 volts difference........ Makes me wonder how that dealer wired all this mess and if they used the correct wire gauge and such. I am guessing that they put ALL 4 batteries on one bank/charging circuit :?Re: GP-PWM-30 OVER VOLTAGE ERROR CA Traveler wrote: 2 comments: 1. The solar controller should be connected to the battery and the battery disconnect switch should have no effect. 2. You should have disconnect switches on the solar panel wires and on the controller battery wires. Especially for controllers may require proper sequencing of these 2 switches. In response to # 1, So then me hitting the BATT DISCO SW and then back on, should have had nothing to do with the issue, good to know, then not may fault/mistake :D And for #2, there are no "switches" that I can see for the panels OR on the controller battery wires, all the wires are connected to "other" wires with butt connections, or am I misunderstanding you??? I pulled out the wires from the wall as far as I could to take a look when I removed the controller, not much to see. Where the dealer installed the panel (dumb location:M), hard to see anything. If the weather holds out, I will get up on the roof and look for, whatever there may be, But I am betting just the connectors from one panel to another and then goes down in to the interior of the motorhome. I tried to navigate the mess of wires, in the battery compartment and under the master bed,(electrical panels/power transfer, etc, etc, etc) but there are sooooooo many, hard to make heads and tails of. Honestly, THAT will take a more of an effort and methodical approach (see previous post on me being lazy) and quite honestly, electrical stuff intimidates me
