Lux ac battery controller

Contact lux and tell them you are pulling a constant 20w, they will adjust the offset for you, should sort it

I seem to have the opposite.. when batteries full and power being diverted to hot water I have a constant export of 120 ish w... not too worried ATM is about 300w a day

Sounds more like the Solic that's the cause of that Mick, rather than the Lux.
You could shut the Lux off from the grid at the CU to see if it still happens.

I was looking at the Lux importer's website and it seemed to imply that you could only attach 5 x 2.4 Pylontechs to even the largest inverter. Is that just out of date information re Pylontech, which I understand can be linked in parallel up to 16 units? Also there was no mention of 3.5 Pylontechs, which is what makes me think the information is outdated.

Apparently, we should be able to see the soh of each Pylontech in the stack with a serial cable plugged into the console port of the master battery.

I can get the overall soh of the stack by sending the command "pwrsys" but can't for the life of me find a way to get soh for each battery.

Can't see this in the Batteryview app either.

Anyone figured this out yet ?

According to the Pylontech data sheet, the max is 8 modules per stack so 8 per inverter.
I'm pretty sure the Lux can take 8.

And am i right that the 8th needs to be wired back to the Lux ?

I would think it would be the same as any other size of stack.
Negative from the bottom batt and positive from the top batt to the Lux.
And make the one with the newest firmware the master battery.

Not quite the same system but on our 3x UHomes both the negative and positive to the inverter come from the master battery. Installers have verified this as correct a couple of times when I've had to send them photos of the install because it's been acting up and they wanted to confirm the wiring and DIP switches.

Yip and I have 4 manuals to prove it. I think that is where I got battery 8 needs to be wired back to Lux but not sure how you would do that.
