Anyone tried the Lux 12k in parallel?

I am wanting to parallel 2, possibly even 3 Lux Power LXP-LB US 12K units. Was wondering if anyone has setup the parallel function on these inverters. I would assume some firmware may need updated. My firmware version is fA1.0.
I appreciate everyone's knowledge and expertise.
Thank you!

Since this is the same Inverter as the Fortress Envy I can tell you that Fortress Power told me that they tested up to five of them in parallel with no issues but for some reason they do not recommend going over 5.
So three of them should not be an issue.

Here are 2 in our mobil show room conected to battaries too. Lux now supports up to 6 in parallel.

I have recently installed (2) Luxpower 12K hybrid inverters in parallel with 28.6KW solar panels in 6 strings and (2) 52V 14.3KW 280Ah lithium batteries in parallel. My system now seems to be working flawlessly as I want.

Luxpower have established support in USA with offices in California. Eddie Wong is in charge of the North American division and is a member of the DIY Solar Forum.

Firmware FA1.0 does not change with firmware update and will remain FA1.0. The build version is what changes with firmware update and the latest public version is FAAB-0D0E. The latest public version for LCD display update is 8. There are beta versions being tested, but the public versions are more stable and reliable. Luxpower will normally recommend using the latest public version unless there is a feature that you need that is only available in a beta version.

I am installing 2 LXB-LP-US 12K units in parallel.

The password does not work on one of them so I am locked out.

The update failed to resolve this.

Any ideas (OTHER THAN A SLEDGE HAMMER)

Elsewhere on the forum somebody wrote the default usernames and passwords were admin and admin. Maybe helpful? Or try admin and leave password blank? Or maybe unit was not new and somebody already changed it. Look for some return to factory default settings.
