I am blessed to have the unnecessary complexity of 3-phase power/expense. The intent is to run 1 phase through/off inverter (2x5KVA). The simplest way to achieve this would be to feed phase X to the inverter (AC-in) and bring the inverter feed (AC-out) back into the existing EL in place of Utility Phase X. The issue is that this will require the inverter Neutral out to be joined at the Neutral input of the EL (hence bonding Utility Neutral to Inverter Neutral out). Is it safe to bond Inverter out neutral to utility neutral? I know with the Growatt's Neutral is bonded to Earth by the unit (by design), so in effect Neutral Inverter out is bonded to Neutral Utility in.

Well, for anyone who opt to go Luxpower, understand you are on your own when it comes to information. I got handy assistance from LBSA on the setup of the battery from the Luxpower inverter end and the LBSA BMS end. The newer Luxpowers support CAN comms on pin 4 and 5, hence a straight through CAT5 or simialr cable works. The LBSA battery however needs the CAN protocol changed from Victron (default) to PN-GDLT to support the Luxpower. Untilthen you will have communication errors and the batteries won't charge. So, on the inverter set it to Lithium, type 6. Set the battery BMS to PN-GDLT - you will need a USB serial cable to RJ45 which needs to plug in on one of the parallel ports on the battery (dip switches all off) no other CAN cables in. The software used is by Seplos. The instructions are in the software folder, however the instructions are typically chinese. So tons of vital information missing. After many errors, I found the software only works on Windows 7 and probably older. I now have 2 happy inverters in parallel and happy fully charged and managed batteries. Just be aware that if you go Luxpower, you are on your own, the agents have no interest in providing support. If you want an easier life, go with Growatt which are very similar, but probably far easier to work on, with wealth of publicly available information. I also find the displays on the Growatt more to the point and informative, the Luxpower look more bling and less function. Cable and basic instructions, rather use the PDF in the software folder, make sure you have a Windows 7 machine to avoid errors importing protocol file: Built Unit Battery Monitor cable | Lithium Batteries South Africa (lithiumbatteriessa.co.za) Drivers, software and guides also available here: Download - Seplos Technology Co., Ltd Load the protocol file, last file in folder (Agreements folder), setup comm and baud rate (19200), connect, login (admin/admin), click on the CAN drop down, top right, select PN-GDLT and you are done. Repeat for all batteries (remember all batteries must have all dip switches to off for this). For two batteries in parallel, revert to dip 5 on (battery 1) and dip 1 on (battery 2). CAN from Luxpower to CAN on battery 1, cable from Parallel port on battery 1 to Parallel port on battery 2 (all straight through). Oh, for 2 Luxpower's in parallel, 2 dips set to on on both units (rule is first and last of the units in parallel must have dips set to on). Then also set parameter 21 to parallel, shared battery in my case to enable, phase detection default (P1), think that's about it. That is fairly well documented in the sparse manual. Hope this helps future unsuspecting Luxpower buyers.

Did you ever come right? I am setting up a similar system. 2 x SNA5000's in parallel with dual LBSA batteries. Suspect I will bump into the same issue and so far I have yet to have the local agents respond to any of my e-mails. Starting to think I should have stuck to what I know, being the Growatt's. Is their CANBus cable simply a switch of pin 3 to 5? Thanks
