technical problems

Post by badr15 » Fri Mar 27, 2020 1:30 am

I hope to help me
I bought (FLEXmax 100 AFCI) and controller (mate3s) with hub
I have two problems:
1 - When programming mate3s it works for some time then it stops working and restarts? What is the solution?

2- When the device is connected to the batteries, the fan attached to the device works for a second, then it stops and never works, and when I touch the device very hot, the temperature reaches 50? What's the solution? To make the fan run...

system information:
System volts:48V
battery amp: 840AH
MATE3S Firmware:1.4.2
FM100-300VDC-AFCI Firmware:2.0.1
Is the software version compatible?

Assuming both pieces of hardware are undamaged, the described behavior is definitely not normal. Something is amiss, perhaps in the system wiring, or another deficiency.

What is the complete list of equipment in the installation?

What is the specific model of battery?

Is the system all new?

Was the system installed by a trained technician or is it DIY?

When the fan comes on in the charge controller is not programmable. Try to measure temps using a hand held laser thermometer you can buy in many stores. Report temps here, like at vents.
Next question: do you observe mate physically reboot or just by looking at events reported in Optics RE?

The Mate3s firmware at 1.4.2 is the latest. For the FM100 AFCI, the website does not list a firmware version yet. The original FM100 (GFCI only) uses firmware version 1.2.0.

A temperature of 50C is not considered to be hot for semiconductor technology. Per p.38 of the original FM100 manual, the fan turns off at 50C, on at 58C, output derating begins at 70C and over temp error is 90C. What are you reading in OpticsRE for the FM100's Output FET Temperature?

New devices(FM100-300VDC-AFCI) I purchased from Amazon
Seller Name:Outback Power
The strange thing is how the device (FM100-300VDC-AFCI) comes with this version(Firmware:2.0.1) and it is not present in the company website and I have not updated it ?

The two issues reported: firmware variations and operating temperature, are minor and not likely causing the problems reported.

There are no reports of firmware incompatibility in current models of OB equipment that i am aware of, and certainly none that cause operational failures, so I suggest setting firmware updates aside as lower priority. Finding the true cause of operational deficiencies should take priority.

Operating temperature is an important factor, but usually comes into play when temperatures exceed rated operating ranges. As a general rule of thumb, operating electronics at a lower temperature is better, but higher temperatures, within proper limits, are entirely acceptable. The power FETs in the equipment operating in the 50°C range is entirely normal, and in fact may be below the point of needing to turn on the cooling fan. That the fan runs for a few seconds at startup then stops is a normal part of the startup diagnostics, and is to be expected.

If there was a true thermal overload event, the equipment would shut down with an error that would be registered in the event logs. 50°C+ isn't that overload point. In fact, it would be nearly 100°C. At that temperature, i expect you would definitely be hearing the fan running.

TBH, it appears that focus is being placed on metrics that are easy to see when looking into the configuration screens, but IME, these are unlikely to be the root cause of the problems encountered.

Something else in the setup, external to the system modules, is more likely the source. Further analysis and diagnostics are necessary, it would appear.

To help further, it would be beneficial to update your profile with a complete list of all equipment in the system. Solar panel models and array configuration, PV combiner box and disconnects. battery model and capacity, inverter, DC Panel and circuit breakers/disconnects, AC panel and circuit breakers, etc.

At this point you may not know what to look for to debug the system, and we can't see enough information to help fully.

An important exercise for debugging, and a great tool that can come from it is to trace every wire and connection in the system, and drawing a simple diagram. The act of doing this may well turn up a wiring error that you, or we, can identify, and that you can correct.

Good luck. We're here to help.

Cooling is not a problem. You are showing an output FET temperature of 57C. The fan does not even turn on until 58C and you will not get an overtemp error until 90C. FYI, my primary career is as a semiconductor packaging engineer. Typical FETs are rated at junction temperatures of 100C or 125C, so Outback is being conservative in how hot they are allowing them to get. This is not something you need to be concerned about. If you are using a metric for acceptable devices temps for a CPU or GPU, these devices with 100+ million transistors are substantially different than the 1 transistor in a FET.

The FM100-AFCI CC having firmware at 2.0.1 not showing on the website is not an issue. The firmware shown for the original FM-100 on the website is different as the FM100-AFCI is a new CC with an AFCI function that required new firmware. Historically Outback has had very few CC firmware revisions and the user still can not update the firmware on FM60/FM80s.

Looking at your FM100-AFCI OpticsRE output, it looks like you are charging and discharging your batteries. At this point, I would focus on making sure your charging parameters are correct for your batteries.

Are you still having an issue with the MATE3s?

I restored the factory setting then the fan worked and the problem was solved

mate3s work fine without problems

Thank you for responding to technical support to solve my problem, and this calculates your success .. Thank you




I have one more question
Filed at opticsre output power 6kW Capacity
While the product data (FLEXmax 100 AFCI)is 7000 watts and the system I have 48 volts is this normal?
I have a system connector 6 power panels respectively
4 sets were connected
I have 24 solar panels, all 6 connected together

Hi, you have two issues with the present panel configuration.
1) With six panels in series, at -10C (14F) your Voc is ~295 which is caution area and at -16.2C (3F) you are over 300V which will cause an FM100 shutdown.
2) Your total panel wattage is 7,200, which is over the 7,000W limit.

With these panels, unless you are in a area that never goes below freezing, I would recommend a maximum of 5 panels in series and limit it 4 strings for one FM100. If you want to get two FM100s you could add another 16 to your current 24 or reconfigure the current 24 into 3 parallel strings of 4 panels.

Watching my 5600W nominal arrays hit 5.9kW for about 10 min yesterday with a cloud edge effect, (109A charging current - the limit set by Global Charger Control), I'm glad that the arrays are split between 2 FM80s with headroom for such an event.

The 6kW indication on the OpticsRE "donut" can be changed in the System Tools/Devices page. Click the gear icon on the main page, then the "network of devices" icon. The setting is in whole kW, so select 7.

Maximum panel power is generally experienced at colder temperatures, but is not the only way it can be achieved. Here in Hawaii, the average temperature is moderately high, and never reaches freezing at my locale. In general use, ambient temperature derates maximum panel power about 20% on average. My 5.6kW arrays (on 2 controllers) usually peak at around 4.2kW.

However, there is a phenomenon called cloud-edge effect that frequently drives array power much higher. When clouds pass in front of, and then away from the sun, the cloud edge can refract and concentrate light energy to a very high degree. If this "laser beam" of concentrated light shines on the panels, output can be driven to much higher than normal output. I have seen the arrays peak out at 6.1kW for periods exceeding two minutes in such a situation.

If your locale never has cold, and never has clouds, then you likely can "get away with" arrays that are over specification. Should there be an overpower event, however, the charge controller's FETs can act as very expensive fuses. Or worse, the charge controller can simply dump the overload directly to the battery. Sudden, high, over-charges can result in some pretty spectacular and catastrophic battery failures.

Do as you think best, but erring on the side of caution is never the wrong path.

You are o'k with regards to temperature with six panels in series but with your 24 panels (4 strings of 6) you are over the maximum wattage allowed for the FM100 under nominal conditions and as raysun pointed out you will be way over with cloud edge effects.

Since you are in a sunny area, like my location in Arizona, another way to look at your present design is that you are wasting ~2,000W of PV. The FM100 can only output 100A which at 50VDC is 5,000W. You will have a much better design if you split your present array between two FM100s, both from the perspective of reliability but also increased power harvesting.

raysun and fcwlp You are right in your remarks
I will divide the array into two devices, each 2 x 6 device
For a power output of 3.6 kW per device, for a total of 7.2 kW
And take advantage of wasted energy
You provided me a great solution, thank you for that
