I charged the battery connected to the inverter that is shut down....off-grid via another one...it was still at 26.4 volts so ok.... thanks Dickson and Sid for the draw info from the LED's it has a built-in bms on that battery but i do not trust the external volt-meter much...
still learning about the pit falls and all !!!!! >>>>
thanks again..😎👍👍👍
maybe the UPS insurance pays them for it>>>I do not know.
You sent the 15 kw to Sean by order of the ebay seller . The PJ seller then collect the UPS insurance and Sean keep the 15kw and it sit and no more communication about what to do with the 15 kw . You got the refund and everybody is happy except the UPS driver . This happen everytime UPS damage a shipment and soon Sean has so many PJ inverter that he has no reason to fix and now he has to design a GS inverter that do not need repair .

sounds like a good way to get their money and their product back for nothing.....possibly that's why they just send them back to California now,,, although the packaging and bracket hold downs to the heavy transformer has improved some...i have sent other damaged electrical appliances back from sellers on Mercari and eBay and Facebook also due to poor packaging...but clearly the seller's packaging does not stand up to UPS mangling them...
UPS probably has good insurance so likely they are in all reality not out much...just part of the business expense so they raise their shipping rates...shipping is quite expensive..🤔🤔🤔

the battery charged back up to 27.2 volts according to the small built in volt meter....I bought a golf cart lifepo4 charger specifically for those pre-built 24-volt lifepo4 packs and it shuts off automatically.... but in the off position the drain to run the PowerJack board's LED lights would be very small on a 5kw battery...
a couple years ago, I bought 8 of those 5kw packs that were pre-built with a built-in BMS from tech direct so they have roughly 40kw storage....
it helps me a lot to understand the "parasitic" load from the PowerJack inverter's board led lights in the off position...
thanks all, it is raining here this morning...
need the rain as it has been very dry all winter it seemed...😎😎
your experiences and replies help this neophyte (me) to understand more.....👍
thanks again...😎😎😎👍👍👍

Yes I made money on ebay that way for three years but stop after fee and shipping insurance is now too much . I get to keep the damaged Lenovo laptop and I rebuild it and resell it again . USPS paid for my refund to the buyer and the shipping for return to me . Everyone was happy for a while including the PJ seller .
PowerJack 30000 watt PSW SP LF inverter:
The heavy inverters i have observed on some YouTube videos are often shipped bolted to a wood pallet inside a wood box...I am sure that increases the shipping cost, but it a quality packaging method...the cheaper inverter vendors do not consider...🤣🤔🤔
usually the styrofoam is smashed, but the double cardboard (by PowerJack) boxing does help....just have to hope they utilize the 6 point bolt down into the case method similar to the AMG 26000 watt transformer bolt down...(that was a secure bolt down of the transformer inside the stainless steel case)...
the heavy 189 pound one from PowerJack they split into 2 boxes to keep under the shipping limit....hope they arrive without damage...😎
sounds like the free parts due to UPS damage was a good business for them for awhile,,,
so now PowerJack advertisements say they do the module design with the transformer in one ss case and the control boards in another ss case to stop the shipping damage... the new module design inverters they are now promoting...
maybe they will arrive without damage....
the 3 ss box 15000 watt one I bought about 2 years ago arrived without any damage and works 24/7... I don't remember the exact date but the price went up to $1600 dollars so I never bought a second one of those.
the best prices were always obtained via auction...
the 30000 watt PowerJack LF PSW SP for $1567.50 including tax and free shipping was on an make an offer eBay listing and they accepted... still a lot, but a larger inverter for sure...
a couple years ago, I bought 8 of those 5kw packs that were pre-built with a built-in BMS from tech direct so they have roughly 40kw storage.
Tech Direct is where I buy some of the Nissan Leaf ev battery with their good BMS . They have good battery and a good price . 40 kw is a lot of money for battery and is the biggest cost for a solar system but is necessary to run 24/7 .
I have went to buying the individual raw 280Ah EVE cells and assembling LiFePO4 batteries the last couple years.
yes for me: for off-grid solar PV setup, the battery has been the most expensive part and the part I try to not make big mistakes with...
I think I have an additional $5600 dollars or so in the 8 5kw packs pre-built LiFePO4 batteries with BMS. today they would cost more I think with the inflation mess going on... they cost about 700 each including delivery....heavy at about 190 pound each...used a makeshift ramp and appliance cart but still a tussle....steps are a killer...they are in a nice case with wheels but they are a bit top heavy....i tipped one over even attached to the cart....should have used two people...
hind sight🤔🤔🤔😂😂🤣🤣 but only my pride scuffed in that maneuver
the Sigineer inverter reviews on YouTube that I watched were protected with a pallet and bolted down via a crate and wood box for shipping....if you watch the 12k and 15k LF Sigineer inverter videos....
PowerJack does the Styrofoam and double box method to try to protect them from shipping damages...
I just have to hope it will arrive ok...>>>>the heavy 30000 watt PowerJack LF PSW SP inverter...
I have never seen the driver board with different color/style where Sean put in the wrong colored one in the GS12K prototype before in any PowerJack inverters.....must be part of their original new micro-sizing designs...????
lots of rain again today....good for the farmers....😎😎 and ducks

It would cost 14400 dollars for me to get eight 5kw pre-built 48 voilts LiFePO4 batteries with BMS today or about 1800 each . My 5kw BMW 67v lithium-ion battery cost 1100 dollars each . I only have enough battery to run 24/7 3 times this year with 13 strings of battery .

Very simple reason:
I DESIGNED THE GS DRIVER BOARDS! And personally hand-soldered all 8 SMD parts to each and every driver board that's gone out in the Rev. C-based GS inverters.
Genetry Solar is not using ANY PJ designs in the next revision units. I personally have designed every PCB in the new GS inverters. They are not PJ designs.

that explains it.... i thought i heard Sean say it was a PowerJack driver board that he put in the genetry solar board that was not compatible and that they were different colors and it was his fault for the board break down.... i will have to watch that Genetry Solar YouTube video again...
my mistake...🤔 not the 1st one I made. on the April 27 2022 sean said he put a PowerJack driver board in it and broke it...i guess i should not listen to them...watch the video below...
the price of LiFePO4 is going up....which will make it more expensive to go off-grid in the future for sure....so more people will go the recycled battery route or maybe a new less expensive technology will come along....one can only hope.
for me DIY battery assembly for off-grid is the best way still....even if it costs a more up-front...
I definitely do like the LiFePO4 vs the heavy lead acid battery system...
I will have to wait before I buy any more LiFePO4 cells right now....

Would it make a better more consistent board to have a PCB board manufacture the board and install the 8 SMD components vs hand soldering them??? they have more precise pick and place machines to do it...
I am sure with the continual changes of pieces and parts in small batches,,,experimenting with the PCB board components and design is ok... "now your doing a revision C version 2 board"
I personally would find it quite difficult to solder all the small parts by hand....but I need glasses for all the tiny stuff...🤣🤣🤣
but applaud your efforts to re-invent a better inverter in a 12k version all the same...👍
