Interesting to watch the evolution of the Hobby Inverter boys. Expecting to be an astounding commercial success with the most "Feature Rich" inverter on the market (yawn). With a competitive price because thay can avoid the huge and expensive product testing and validation (or rather, they don't...

These guys have developed the most rugged output configuration of their MOSFETS in the industry and will tolerate any kind of abuse or stress with zero failure. The most indestructible inverters on the planet. Combine that with the most feature rich inverters and you have real industry...

You didn't see this in my post: Replaced 12 flooded lead acid golf cart batteries today. Total capacity 620 A/H at 24 V = 14880 kWh Using cheap garbage Interstates from Cosco total cost $1300 Batteries were 5 years old. Did a quote for a LifPo4 battery. Of course you only need 7 kWh from LifPo...

Oh yes, among my numerous published articles, this one on inverter reliability: http://www.how2power.com/newsletters/2201/articles/H2PToday2201_design_RedHillLabs.pdf?NOREDIR=1

Two years ago I developed the worlds smallest operational amplifier https://www.onsemi.com/products/signal-conditioning-control/amplifiers-comparators/operational-amplifiers-op-amps/ncs20282 https://www.onsemi.com/download/data-sheet/pdf/ncs20282-d.pdf

When I did they were audio transformers, some mic input but mostly tube output stages. The toughest problem was leakage inductance that was dealt with by progressive winding interleaving until the limit was reached when a/3N^2<c where a is total winding thickness, N is the number of leakage flux...

Good point. I need to get professional help to quit posting on message boards. It is a sick addiction.

I probably should get professional help to quit posting on message boards. I really need to quit.

It's clear that everyone here is an expert. Thanks all!

Everyone seems to have an answer for everything. I like being told how I will have to build the system I already have and how virtually impossible it will be.

7000 watts 24 volts, and my existing system is 4000 watts 24 volts and the two MPPT controllers I have makes an irrelevant level of improvement compared to its cost. Also running two conventional controllers.

I've got regular charge controllers and MPPT charge controllers. My experience for over 10 years is that the MPPT isn't worth it, at least not here in the sunny Arizona desert. My upcoming system upgrades include upgrading to non-MPPT charge controllers.

Lots of epsilon minus at Genetry. Most of what they do, say, claim, and their prior experience is "not even wrong".
