[RE-wrenches] Schneider XW+ and Midnite batteries

[Kevin Pegg]

A word of caution – the XW Pro is, IMO a major downgrade from any previous XW’s. The newest firmware causes all sorts of power quality issues if you are running a generator. Like it literally smoked electronics for some clients. Schneider knows, they just don’t care. There’s good reason these units are going cheap now to dump obsolete inventory.

XW Lithium integration is through the Insight Home or Gateway monitoring devices. It can be done, but in my experience it’s constantly glitching out and not delivering reliable power solutions to clients.

I generally recommend to clients if they want newest battery tech, let’s upgrade the inverter as well. Less call backs.

I just had a conversation with someone about this the other day and he recommended buying an xw pro which he said has the latest firmware and can do lithium communication much easier than the older xw.

I haven’t researched it but if true you can buy a new xw pro from NWS for under $900.

Has anyone successfully close-looped a Schneider XW+ with Midnite PF16 batteries, or any other battery BMS that uses Pylon? I have a client that currently has an XW= running on a set of 2 volt Surrettes that are failing.  I'd like to switch him out to an AIO/PF16 system, but want to give him the option of keeping the XW+ (which is paired with 2 Outback150vDC Charge Controllers). The mixed brand Inverter-Charge Controller setup gives me some pause if keeping that, but if necessary, I just want to hear success stories if they are out there.
Thanks,
