If the EG8010 has a software limit of 189
The EG 8010 inverter board I bought is 50 dolars on Ali express . My Powerjack transformer primary do not match so is limit to 189 vac . Ali express do sell a matching transformer for EG 8010 and cost 600 dollars . Sean has a lot of old Powerjack but PJ in China no longer make repair parts . I find that using a EG 8010 inverter board will not make old Powerjack useful . IT will be very difficult to repair old PJ inverter .

Doubt it. The voltage feedback input requires a voltage divider--so in theory, it could be used to regulate almost any output voltage. The issue is if the SPWM output cannot flat-top/distort the AC wave if there's insufficient headroom. On top of that, it might not even take the sine to full 100% max PWM throttle anyway--further reducing headroom.

The inverter board has output voltage adjustment . IF output ac is adjusted too high it shut down with red light blinking . IF output ac is adjusted too low it shut down also so now at 130 vac it works to run a light bulb . The battery is 55 vdc input . The inverter board has over voltage and under voltage protection adjustment . IF the adjustment from the factory is out of range then the EG 8010 will not start and may blow the FETs if it shutdown automatically under load .

This EG8010 discussion is interesting, but perhaps you can buy a parts inverter from Sean and repair your old PJ? I would like one of the working 24V PJ's, but all depends on $. Lots of bills come due for me right now.

I figured that was the case. So he just needs to adjust his tranny to get enough voltage.
Unwinding the primary a few turns would clearly do it, but with less copper, what side effect is produced?

I haven't heard anything more about this. Sean is nigh impossible to reach sometimes. 😕

At some point, this week, there will be a link on genetrysolar.com with info on the available PJ inverters that he's tested.
the egs002 little board is looking for around 3 volts from the voltage divider on the big board so as sid said it can be made to reg almost any voltage with in the specs of the parts like caps fet ...... if you can do so in a safe way "know what you are doing" you can plug one 120 volt leg of your tranny into a wall outlet
after plugging in see what the low side voltage is
if it is 36 volts you will need to unwind a few turns
then plug it in again and check the low side again if still over 28 volts you repeat
untill you get 28 volts if under 28 you add turns to low side check it each time
do this until you get 28 volts
from every thing i know any esg002 inverter over 2k needs to have totem poll drivers
you will also need a realy good choke
my buddy has been using one of my home made 10k egs002 inverters for a long time now every day off grid
they can be good inverters but what is the use now that GS is making much better inverters?

YES need totem poll LF driver and a big choke . 10 kw seem to be the limit for DIY inverter and Powerjack inverter . I stop using the EG 8010 with the ASL 9.0 transformer and is using the rev 11.3 PJ control board now with the transformer primary to 32vac .
i never liked the power jack control boards one bank of fets gets hotter than the other 3
i had a buddy that reprogram a pj control board for me and it ran great he may have done other stuff to it also not sure
but it truly ran great after he done what ever he done
the egs002 can be made into a good inverter but it is plain jane and i have never ran one at over 4or5k for hours at a time
i have ran one with big load for short times here and there
i would not trust them for every day use of over 6k i have had no prob but people way smarter than me have said over and over 6or7k is tops for the egs002
PJ and esg002 suck when compared to even just the GS wifi board
ITS DAY AND NIGHT!!
GS is no more in cost when all is said and done either
Have you seen all the things a GS wifi board can do?
Its not just a screen with wifi its all the brains and drives the fets at 8amps!
This makes sure they turn all the way on fast so less heat and losses
It was a crazy killer deal when they was selling the wifi by its self for 3 or 350 bucks
To anyone who had a junk pj could buy the GS wifi install it and turn a junk into a very nice inverter
Of course you have to no how or know some one that can install it for you
The pj fet board is not the prob with pj inverters or at lest the pj i had
They work great with GS wifi i have had one since before the first wifi was sold
ITS still running strong!
The wifi does not make the tranny bigger
But you turn a junk pj into a very nice inverter with tons and tons of feachers like wifi that can do what ever wattage the pj tanny is capable of
I quit messing with esg002 and pj when i got a GS
All in cost is about the same from home made esg002 or buying a GS it is a no brainer lol
If i had a large pj inverter i would be trying to get my hands on a GS wifi board to put in it
That is my two cents on it all!
