GS8048A Module Temperatures

Does anyone know what would be a too high temperature for the Module Xfmr Temperatures Module Cap Temperatures Module FET Temperatures on a GS8048A as shown through OpticsRE? Due the high ambient temperatures in my area would it be appropriate the set module operation to BOTH rather than AUTO so tha...

Re: GS8048A Board failures

I've had four power control board failures since 2012 on an original GS8048 and a replacement GS8048A and thats on an off-grid system being used only about three months a year. I have three PCB spares now and suggest you do the same. I do have a theory about what has caused the failures and have a c...

Re: GS8048 replacement with GS8048A-01

Since 2011 I've had 3 control board failures and one inverter module is currently failed for which I've not been able to find a Spare-201. When I have the 8048A working I may ship the bad module back to Outback for repair. But from my location the shipping and customs and VAT costs are so significan...

GS8048 replacement with GS8048A-01

I'm about to replace my GS8048 with a new GS8048A-01. Cursory examination seems to indicate the replacement is a wiring copy of the old inverter, i.e. wire it correctly, power it up and I should be good to go. The system includes a GSLC, Mate3, Flexnet, Legacy Hub16. I'm not grid connected. Neither ...

Re: can the 8048A handle a conventional well pump?

If you think about it in a solar powered home you should be using LED lighting and gas (LP/NG) cooking. Other then maybe a coffee maker or some other lite electrical appliance almost all of the larger loads will be motor loads whether tor a well pump, refrigerator, freezer, tools, etc. How could the...

Re: GS8048 Failures

My max environmental temp is 85F with excellent ventilation. What published manufacturer recommendations are you referring to? I also note that there are more posts than mine detailing Power Control Board failures. From the datasheet - At temperatures up to 122┬░F (50┬░C), all inverter components me...

GS8048 Failures

I'm starting a new post on these failures because I think I understand what is going on and anyone who owns one of these inverters should be aware ... or beware.

Re: GS8048 Control Board Failure

The damage is significant. The bottom of the scorch looks like it crosses two etched tracks pointing to TP1 per indication on the board. Above that the damage is so great it's hard to tell what was there. Further up on the board the scorching looks like flame damage from the base of scorch. If you h...

Re: GS8048 Control Board Failure

The first two failures exhibited no distress. The boards looked perfect in every way. This 3rd failure left about a 1/2 in^2 scorch mark on the front surface. This contrast is worrisome as it may indicate additional damage deeper into the stack where the repair costs escalate into thousands of dolla...

Re: GS8048 Control Board Failure

The nice thing about island living is that the ocean moderates the air temperatures and there's almost always a mild breeze. Winter temps seldom go above 85F and we go back to our WV mountains in the summer leaving the solar totally shut down. Having said that I have thought to install a muffin fan ...

Re: GS8048 Control Board Failure

Salt air is easy to blame but the installation is a couple hundred feet from the water and within a building. Usually I see corrosion residual if I'm under salt attack. This last board was clean as a whistle and has been in service less than a full year. I have electronic devices that have been in t...

GS8048 Control Board Failure

This topic has been discussed to some extant in other posts, but I've not seen a clear solution: My GS8048, s/n 000131 has just experienced its 3rd Power Control Board failure (the small circuit board on the top of the board stack). First was in 2015, second in 2018, and now in 2019. I am completely...

Re: Bad Power

Sure sounds to me like a grounding or neutral/grounding problem. For example, your neutral should be grounded at only one location in the entire system (assuming no isolating transformations). Perhaps the generator manufacturer provided a grounded neutral; perhaps your electrician wired it that way;...

Re: OpticsRE/FNDC - New Physics

Should have been more clear that I was pointing out more calculation defects in OpticsRE. The data is a text copy and paste from OpticsRE/Device Map/Port2(FN-DC). So the data is supposed to represent whats going on with the battery. The point was that an output current of 5 ADC @ a voltage of 49.8 V...

OpticsRE/FNDC - New Physics

So its raining cats, dogs, and frogs here and I don't have anything to do but swat mosquitoes and wonder how an Output Current of 5 ADC @ 49.8 VDC gets me an Output of 4.84 KW and an Input Current of 5.8 ADC @ 49.8 VDC gets me an Input of 1.39 KW and my only source of power is solar at .26 KW #-o :-...

Re: My Flexmax 80 Thinks it is a Flexmax60

Red.

I was aware of the counterfeit issue and everything seems to check out as real. I even have the original assembly bar codes that come packed inside.

The essential info is S/N FM80S46494 FW 2.1.0

I think this is the real McCoy.

Re: My Flexmax 80 Thinks it is a Flexmax60

I just went through the same issue. In my case I had set the FM80 on the 2205 watt array to 45 amps thinking I would provide some additional protection against against high battery charging current until I had time to evaluate how the addition of the larger array affected charging performance.

Dashboard Power Flow diagram is incorrect

The power flow diagram on the OpticsRE Dashboard indicates solar power produced via the CC flows serially through the battery to the inverter. It doesn't. It flows through parallel branchs to both the battery and inverter. The error is replicated in the Summary bar graph with huge "To Battery" and "...
