The story of generator power dismissals and lacking MPPTs

My name is Normie.  I am a youngster that still remembers high school maths & science.  I liked those subjects.  I did good in them.  I have a 12V 60W appliance.  I sometimes power it from my 12V 7Ah SLA.  Sometimes I power it from my 55Ah car battery.  I even connected it to my old man's 200Ah AGM he brought the other day for L/S.  I know that the voltage is the important thing to get right.  I know if I connect my 12V appliance to a 24V battery, I will eat toast.  I understand that if supplied the correct voltage, my appliance will only draw as much current as it needs.  I calculated that my appliance needs 5A.  My multimeter agrees.  Now I made a MASSIVE investment in a SunSynk.  I also brought some solar panels.  Now the guys tell me my panels are too "big".  They say my panels can supply more current than my SunSynk's 11A limit.  They say I can't use them.  Now I am angry.  I am confused.  Nothing makes sense anymore.

Because I couldn't connect my panels, I decided to connect my 5KVA genie to the SunSynk.  I have been using my genie for over 2 years.  My genie can power ANYTHING.  My fridge. My microwave, my TV.  No problems.  I know why.  My genie produces the perfect sinewave.  I have a friend.  He gave me his toaster.  He said toaster no good.  Toaster screams at him at 15kHz whenever his SunSynk kicks in.  But the toaster is fine.  It doesn't scream at me. I have been running it from my genie.  I heard someone say it is as result of switching noise that inverters produce...  Well, can't they filter that???   Can't they make it switch faster so that people can't hear it?  But anyway, now my SunSynk doesn't want to accept the power from my genie.  Why?  EVERYTHING runs from my genie.  I know my genie has AVR.  It battles to keep the genie's speed constant when the load changes.  Speed variations cause output voltage and frequency variations.  I know all that.  But ALL my appliances have been happy with my genie.  They don't seem to be fuzzed about the voltage and frequency fluctuations.  Why isn't my 30K SunSynk happy?  I am really angry now.  Nothing makes sense. I think my high school teacher must have lied.  I don't think I should follow the science anymore.  I think I made a mistake.  I should rather have invested in Flintstone equipment instead.

I understand slightly more than Normie.  I understand that with the topology of modern inverters, the reason why they drop the genie input.  I however, do NOT accept that a 30K inverter is too much of an aristocratic snob to not even allow me to power from a genie via a different input.

What is a MPPT?  It is a Maximum Power Point Tracker.  It is a switched-mode power supply controlled by a microcontroller or DSP that implements a fancy control algorithm.  It measures the input and output voltages and currents.  It slightly changes the duty cycle of the applied PWM and then determines if the output power into the battery, increased or decreased from the sample before it.  It will then re-adjust the duty cycle to optimise power transfer into the battery.  It will repeat this algorithm to correct for any environmental change such as shadows forming over my panels, etc.

I believe there are some so-so MPPTs and some good MPPTs.  I presume there are different algorithms that can be used to implement the mppt in the digital domain.  I have worked with 8 and 16-bit microcontrollers.  I don't know DSPs.  I don't know the EXACT details of MPPTs. I am no power electronics expert. I am a jack of all trades. Frankly, I was VERY surprised at the input current limit of MPPTs. I don't understand it.  But let's assume there is a good valid reason that MPPT implementations are not so clever as to self-limit power take-up.

Can we agree that the MPPT is a SMPS with intelligent control?

The hardware of a high voltage MPPT can typically run from 120V to 450VDC.  So if Normie would run his genie through a very large bridge rectifier, followed by a high voltage smoothing capacitor, he would get 330VDC.  330VDC fits in perfectly between the 120 to 450V limit.  But now Normie can't do so, because there is no current limit function on his genie.  I suppose Normie could connect a B_I_G wire wound heating element (I refuse to call it a resistor) in series with the genie's output, but that is utter stupidity in a world controlled by DSPs.

Why can't a SunSynk (or an Axpert for that matter) not allow the user to re-configure the MPPT?  Instruct the MPPT not to execute the mppt algorithm, but only act as a "normal" SMPS with an implemented intelligent battery charging algorithm?

Mmm?  Please inform dof over here why this seems to be impossible.

I suspect the answer might lie more with company politics, bean counters and marketing men, in the drive to move people into higher valued products or sell add-on solutions.  Companies the world over have been using MIPT technology for their product and marketing decisions.  Maximum Income Point Tracking.
