Re: [RE-wrenches] Location of DC disconnect vis-a-vis rapid shutdown exemption

Hi Rebekah; Thanks for pointing out the changes to the diagrams.  I especially appreciate Note (2). /The PV system disconnect in these diagrams separates the PV system from all other systems./ That seems simple enough for defining the boundaries of RSS, until you think about off grid, and

Re: [RE-wrenches] 3-phase with storage

I have done it, not hard but limited to 32 kw for backup power, 120/208 3 phaze using Outback FXR On Tue, Apr 17, 2018, 1:19 PM Marco Mangelsdorf wrote: > Aloha all. > > I'm on the hunt for workable options for a PV plus storage design for a > 3-phase 120/208 application. >

Re: [RE-wrenches] 3-phase with storage

We are building a similar system presently, 60 kW Sunny Island Inverters, 400 kWh battery storage (FLA), dual 100 kW backup generators, 25 kW PV, 5 kW microhydro. Don't know what raw capacity you are looking for, we also use XW inverters for smaller systems but find they don't scale nearly as

Re: [RE-wrenches] 3-phase with storage

I do not want to sound like I am plugging Discover AES batteries and there use with Schneider and soon Outback. There web page has a 3 phase XW+ system on it and all the coms built in to the BMS to work with Xanbus. AEE had a webinar also last week. It is on their U-tube channel. Dave Angelini

Re: [RE-wrenches] 3-phase with storage

SMA Sunny Island, Outback, and Schneider can all be configured for three phase systems. On Tue, Apr 17, 2018 at 1:47 PM, Marco Mangelsdorf wrote: > Aloha all. > > I'm on the hunt for workable options for a PV plus storage design for a > 3-phase 120/208 application. > > And

[RE-wrenches] 3-phase with storage

Aloha all. I'm on the hunt for workable options for a PV plus storage design for a 3-phase 120/208 application. And there ain't much out there at present. Any suggestions would be appreciated. mahalo, marco ___ List sponsored by Redwood Alliance

Re: [RE-wrenches] Location of DC disconnect vis-a-vis rapid shutdown exemption

Hi everyone, I strongly recommend looking at the figures that were added in NEC 2017 at the beginning of Article 690 in 690.1(b). What they show is equipment that is part of the PV system (to the left of the PV system disconnect called out in the diagrams), and equipment that is not part of the
