OK, thanks. It's back to the drawing board for me.
Would it be safe to connect one or more coils to each hot line and then the shared neutral?
The 1/2 hp pump is 230vac so one or more choke on L1 and one or more choke on L2 but no choke on neutral . The 115vac motor will have one or more choke on L1 and neutral will have one or more choke . L2 will have no choke since it is not used . I would not connect 115vac motor and 230vac pump at the same time .

i have one of those chargers/tester for the LiFePO4 cells but I really like the Riden 6024 bench charger
I brought the Riden 6024 like yours and I charge 2 LIthium-ion battery in parallel in 2 hours instead of 10 hours and it will reduce the amp to 0.1 when the battery is charged and never overcharge the battery . This fast charging help in using the battery at night . I can charge 10 battery in 10 hours and have enough battery ready for the night .
But as far as starting power / total starting surge, etc., etc., they will not make one whit of a difference. The real issue is the poor FET gate drive in the PJ inverters.
A bigger transformer like ASL5.0 would fix any 1/2 hp pump starting problem . The inverter PJ design is so bad that I no longer do anymore testing after the cable I bought could have blow up all my battery by bad crimping of the terminal end and arcing and fire .

I have always made my own inverter cables with 4/0 copper cable... the cable is then hydraulically crimped wit a 12 or 16 ton crimper ... i think it cost about 60 dollars for the crimper (12 years old) and the cable was 4 dollars per foot... I think the cable is more now unless you find a bargain on eBay....copper cable has definitely increased in price..
it seems most inverter cables they sell are not adequate so best to make your own,,, you can depend on the thicker cables at high amp draw... i also only use the tinned cable lugs and use adhesive lined shrink wrap to insulate the ends and limit the exposed metal...
have a safe and relaxing weekend...😎

The photos on Ebay of the Power Jack chokes seem to show both hot and neutral AC power going through the coil. When I start testing the 230 pump start, I may also have a small 115V load running, because that might help to start the 230V motor.
I will be quite bemused if it's determined that both lines going through said choke...are found to go through the toroid in the same direction.
(If they go through in the same direction, they will cancel each other out--and the whole box will be completely useless.)

The coil has two separate windings and PJ is not stupid to make that mistake .

OK, thanks.

You think??
🤪🤣🤯
The windings are separate, yes, I understand that. But the direction that the windings are wound on the core is important. If they're wound the same direction (which I bet they are), they'll cancel each other out.

I bet PJ know how to wind wires around a choke in the correct directions . PJ had to be really stupid to not know the directions of two wires . They are stupid in crimping wires as on Sean youtube of the GS 12 kw . I bought 3 AGW 0 wires a year ago for 15 dollars each on ebay . One crimp came loose last month and the insulation is on fire . Last week another cable also had the insulation on fire when the crimp come loose . I remove the third cable from the bus bar and battery .
it seems they have no confidence in any powerjack inverter and choke or winding knowledge,,, so why would they utilize them as their manufacturing company??? powerjack...????
it seems to say they have no manufacturing knowledge and very poor quality control....after some 12 years of selling powerjack inverters...????
maybe they need to start with a more reputable company???? as always bashing their own manufacturing company....sure makes one have doubts ....especially after the obvious fraud of their seller rayjunglepower. and powerjack-jack....
maybe powerjack-jack is a fraud also...with any number of fake names on eBay???

the gs went from the 6 plus fan hype wifi board to 2 fans to cool the toroid, and extra windings on the choke was supposed to help, but that was in Sean's YouTube video of old... the extra jet engine noisy fans were not practical in use or expense...evidently
the competition's LF inverter with copper wound iron-core transformers don't require as much cooling as the aluminum wound transformers to prevent the saturation and overheating problems. that is why they (the LF inverter competitors)use copper windings...along with the ease of assembly that Sid talks of routinely...
I think that is why they (copper wound transformers) have a higher surge capability ,,,,because they do not become saturated so easily...when they become overheat and saturated they loose their magnetic capability and their performance goes down the tubes (the aluminum wound transformer)....so have to run them (aluminum wound transformers) in an air conditioned room to get higher output and prevent overheating...
they can not run at 12k continuous in a hot room for any length of time...they likely will run into the saturation issue due to the iron core heating up and the wire heating up...
I want to see the four gs12k inverters with all the mppt solar charge controllers in one room running at once...even the batteries do better closer to 72 degrees F...
if you watch the recent Sean YouTube videos....they are only running at 5-6000 watts most of the time or less and only short times at higher wattage at least the live feeds Sean is showing...and the temperature is clearly going up....but he has the solar panels helping a lot..
makes me wonder why he would need 4 of the 12k inverters???? not enough panels or batteries yet....
he would be safer to move the batteries into a fire proof enclosure out of his living quarters....
I still need to read up more on the toroidal transformer vs other u-shape/e-type transformer though...
have a great Sunday😎
maybe powerjack-jack is a fraud also...with any number of fake names on eBay???
I google the 60 days the bank will accept dispute and it say IF it a case of fraud like sending faked mail then there is no time limit and you will get the full refund from the bank if you charge with credit card ( not debit card or cash ) .

I happen to buy the same lithium-ion LG pouch battery that Sean bought at the same time also and mine is outside in concrete box and no wood near the battery . The lithium-ion battery will explode at 400 degree F and wood is 500 degree F when on fire .
