Re: [RE-wrenches] Classic 150 100 amp output breaker tripping

thanks all for the thoughts. Ended up replacing all breakers and the controller and the problem has gone away. sent the controller back to midnite and came back with no issues so we are assuming it was the breaker. Daniel Tittmann CTO Greenwired www.greenwired.com dan...@greenwired.com

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

I might take a clamp on ammeter and check the Classic's battery side current. Then maybe turn ON the generator and see what happens to the current on that line. boB On 11/6/2015 1:49 PM, Daniel Tittmann wrote: there is a MNSPD 300 AC and a MNSPD 300 DC. are wired into the system. this

there is a MNSPD 300 AC and a MNSPD 300 DC. are wired into the system. this is a new system. Has been happening since commissioning. it is possible that the generator is charging during those morning hours as there are likely morning loads, coffee pot, but not always as the customer just went

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping

Good tip, and also prompts me to remind that a thermal camera will see a lot of problems the eye cannot. We have a fluke thermal camera and I make it a practise to survey a customer's electrical room prior to doing a proposal, as identifying the overloaded components can help to avoid the blame

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

Allan, No, not suggesting to get rid of E-panels or wiring centers. They aren't optimum though, electrically speaking. My suggestion was more of a technical one intended to illustrate a way of wiring to reduce stress on (most) MPPT charge controllers. I should not have said it was a a good

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping

Some years ago, we had a similiar problem with a 50 amp breaker nuisance tripping, we over analyzed the problem and still could not prevent this erratic issue, sometimes it would work fine for weeks - sometimes days apart, sometimes on sunny days, sometimes on cloudy days. In the end the

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

boB, I appreciate your contribution to this discussion, but it brings up a couple of issues for me. - You have suggested that "A good wiring practice these days is to...wire the controller's battery terminals close or right at the battery terminals." This

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

You don't want to drive for hours and hours to do something that might not fix the problem. Without knowing exactly what is happening, I would bring a spare Classic and also a new breaker which I think I heard we were sending you If the Classic is plugged into the internet, there is

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

This is probably not the breaker at fault. Could be, but just doesn't seem like the only thing I would suspect. Do you know if the generator might be turning on and charging the battery through the inverters at this time in the morning ? Since you were talking about the AGS it makes me

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

After the Magnum Inverter/charger samples incoming AC power, they have a slight delay before starting the charger. Then, they ramp up current slowly. Even so, how will any current from any other source pass through the breaker unless the Classic is presenting a load? I suppose something else

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

Daniel, Very strange problem. While I agree that you should try replacing the 100A breaker, I doubt that it’s the problem. Why would a breaker trip at low amperage in the morning, but not trip at noon when the amperage is higher? At early morning turn-on, the voltage might be too high,

Re: [RE-wrenches] Classic 150 100 amp output breaker tripping?????

Larry, because these MPPT CC's are bi-directional (for efficiencies' sake), they can convert a large current at the battery side to a smaller current at the PV side if not adjusted right. Normally this is just taken care of and reduced to a bare minimum by the controller watching the
