Priority Power Node Excess Sent Into Grid

Wouldn't it be simpler to connect the automation wires directly to power transformer input instead of using power shutoff?

Yes, but you lose the energy stored in the transformer.

Thanks, I didn't think of that.
Which is better? : Putting the power shutoff on low capacity side or putting it on high capacity side of power transformer.

I can't think of an advantage to putting the shutoff after the transformer output rather than before the transformer input.

Why the 3 battieres? Couldnt you do the same thing with 1 battery?
Connect the automation from Battery -> power switch -> not gate -> other power switch. Then set the battery to active 60 standby 50. Should make the battery float around 55% power
2
The third battery is extra storage. You can do it with one but you might as well set the thresholds to 90 active and 100 standby. Otherwise you're wasting a bunch of storage capacity while still suffering the same runoff.

Wouldn't you be able to buffer an amount of hydrogen for the the SPOM? and send excess to another Hydrogen generator for main line. This keeps the circuits independent and sends excess energy to feed the grid.
2
You could but doing it this way mitigates most of the hydrogen production from the electrolyzer without need to ship and store the hydrogen elsewhere. SPOMs are also frequently complemented by wheezeworts so the additional heat generation for running the generator more frequently is usually offset.

I'm borrowing this as we speak. I've been trying to figure out how to keep my SPOM from bottlenecking at the hydrogen side. This, plus another not gate and gas shutoff from a high hydrogen area, I'll be running that sucker for quite a while, lol!

Wouldn't it be easier to dump the H2 generator output directly into mainline, and power SPOM via an isolated circuit set only to consume power?
Otherwise, it's brilliant in general for balancing two circuits.

It would be easier but it wouldn't be isolated. Remember that SPOM stands for Self Powered Oxygen Machine. The SP portion indicates that the device is capable of powering its own operations once primed. The hydrogen generator is there to serve the SPOM first and foremost. If you route the output from the generator into the mainline then the components of the OM are competing with everything else for power once the SPOM batteries behind a transformer deplete. What this design does is prioritize the power from a generator to a specific purpose and only allows excess to the grid once a certain threshold is reached. This means that whatever happens with generation or consumption throughout the rest of the grid will not impact the priority system.
This also has a second factor. A SPOM will not operate a generator 100% of the time. A normal SPOM creates a hydrogen surplus which you must deal with. This system causes the SPOM to operate nearly 100% of the time which mitigates the hydrogen storage problem down to 12g/s by trading the hydrogen storage/consumption problem for additional heat generation. I don't believe the heat generation is likely to be a big problem due to the usage of worts in SPOMs so the main issue could just end up being O2 that is a few degrees warmer.

If I correctly understand your argument then feeding the mainline solves all the issues. It is setting the H2 generator to maximize uptime, so the H2 excess is also 12g/s (or lower if there is O2 excess). There is always an option to just add a second H2 generator to consume H2 overflow.
It does separate the OM from the generator, true, but the mainline does allow for prioritizing sub-circuits over each other. The priorities obviously go as O2 and power production sub-circuits at the top, and everything else after that.
(Also I do not use worts at all but that's another topic)

If you can set priorities on which transformers will get power over others then that may mitigate the power transfer problem but it does increase the potential scope of any problem solving if your SPOM stops working. Using a system like this with circuit breaks means that any problem with a SPOM not functioning must be isolated to the SPOM and not at all influenced by anything outside of it.
Additionally, if you can't run heaviwatt to the generator then you have to use a transformer to step up your regular wire to the heaviwatt. This could be a heat related issue if you're trying to insulate the SPOM so that the heat production from it doesn't leak out into the surrounding areas.

I do this very differently. My "SPOM" produce just enough power for itself. This means I get an excess of hydrogen instead. This I can use other places, like in an Anti-Entropy Thermo Nullifier, cooling chambers using Wheezworts, or power production for other things.

I had previously always used a shut off transformer to connect my SPOM to the grid so that if it ever shut down and the batteries were depleted I could close the circuit and have the grid charge it to get it going again. However, I realized that the SPOM was power positive so I wanted to feed the excess back into the grid while leaving power in the batteries for the SPOM. I didn't want to create a contraption to store the excess hydrogen.
This was my contraption.
I use the charge levels on two different batteries to open/close the shutoff on the circuits leading to the inbound and outbound transformers. The inbound is set to go active at 15% and standyby at 10%. The outbound is set to go active at 100% and standby at 70% but that signal passed through a not gate to toggle it to inactive. You may also note that a conductive wire goes into the input of the large transformer with heaviwatt coming out the output of the large transformer.
The end result is that the SPOM is isolated from the power grid at all times when the battery is between 15% and 70%.
Edit: One minor edit I have to make. The large transformer needs to be a small transformer otherwise when the SPOM is transferring energy into the grid it causes a circuit overload. This means the design is only possible since Expressive.
Edit 2: You have to use conductive wire over regular wire if you want the outbound transformer since that would put the max draw potential on the circuit at 1600W.
