Lux ac battery controller

Excellent.

So, I now know the Fogstars will work with SunSynk, which has provision for islanding. I just need to find out if the 12kW Lux can also trigger a contactor when the mains fails. The extra 4kW over the Sunsynk would be reassuring, when running a heat pump.

Not sure if this is what you mean but I have the 3.5 Lux with esp. The lux has the esp always on. The external independent contactor to link the wiring on power cut is on an always on to stop the connection so when the power cuts the contractor fails and creates the neutral/earth bond. 

Not sure if that makes sense!

I looked at the 12kW Lux specification, again, and I realised it only has a 3.6kW ESP, which seems a bit of a waste of a large inverter. Unless I've misunderstood, the SunSynk has it's whole output capacity available, for the whole house, when it triggers the isolating contactor. Sunsynk are very popular in South Africa, where load -shedding is a daily occurrence.

Just noticed my invertor, although it shows the correct BST time on the dashboard, isn't behaving as though its set at the correct time.

Its still working at GMT times in the discharge/charge settings.

Any ideas?

I would give it a few hours before messing with anything, I've done that before and it sorted itself out later in the day

It seems to have.

But now I've got this message on the Octopus Charge dropdown menu in Maintenance:

"The changes before 9pm will be updated by the server today, and the Octopus settings will take effect since 00:00-23:59 in next day. The changes after 9pm will be saved but updated by server in next day, and the Octopus settings will take effect since 00:00-23:59 in the day after tomorrow."

Which is probably why when I changed it from 1 to 6 blocks yesterday evening, it didn't use 6 blocks, just 1 and I'm having to be real tight with leccy today!

Anyone know why they have introduced this change? Its very inconvenient.

I'm looking to start exporting power actively this year. My solar system was never registered, so the DNO are currently registering it via G99. What settings do I use when I want to discharge the batteries and do I need anything enabling by infinity?

Shouldn't need infinity to do anything - if you're planning to discharge on a timer there's a set of forced discharge time settings in the same way as AC charging.

Question for the learned people on this forum. I have a squirrel pod ACS3600 inverter with uhome batteries, I'm looking to expand the system and add a 2nd ac coupled ACS3600, can I use a different battery make linked to the second inverter? I have asked Lux as well to see what they come back with.

I wouldn't ever call myself learned, but I can confirm you can use two different batteries on the different inverters.
I ran pylons on one and fogstar on the other for about 3 months.
Only thing worth noting is that the cells of the battery will give it a resting voltage.
Pylons have 15 cells, fogstar have 16, and so they sit at a higher voltage.
What this means in real terms is the lux will use the higher voltage battery before the lower voltage so your soc's won't be the same, and the 16 cell battery will be depleted first.
Not a massive problem,  just worth being aware of

Well found out what was causing my SOC loss just over 1%/hour, having my old battery in the stack with new ones. I've removed the old battery from the stack and had no loss whatsoever overnight when the batteries were on standby.

That’s a bit of a nightmare.

Yes, sounds like a duff battery!
