Re: [RE-wrenches] seeking 3ph battery based/backed inverters and experiences

Hi Guys, Ideal and Princeton have both exited this space. Delta is solid, there is also Dynapower with a 125KW class and larger.  -Wes Kennedy 303-653-3073 On Wednesday, April 21, 2021, 12:54:32 PM MDT, Lloyd Hoffstatter wrote: A couple of other sources – Ideal, Delta and Princeton Po

Hi Chris, Another company that may be worth looking at is ELM. http://www.elmmicrogrid.com/ It looks like they have some 480V commercial packages. Cheers Dave On Wed, Apr 21, 2021 at 3:48 PM Chris Schaefer wrote: > All good ideas, but what I'm trying to avoid is putting 3 inverters > together i

Re: [RE-wrenches] seeking 3ph battery based/backed inverters and experiences

All good ideas, but what I'm trying to avoid is putting 3 inverters together in order to achieve 3 phase. I did take a look at the Delta unit suggested by Jay and intend to contact them for more details. So if you know of a single inverter setup that provides 3 phase in a BBU and Microgrid configur

Re: [RE-wrenches] seeking 3ph battery based/backed inverters and experiences

A couple of other sources – Ideal, Delta and Princeton Power all have larger battery based (typ. 480 VAC) inverters. Some info on Ideal 30 kW https://www.idealpower.com/wp-content/uploads/2016/02/30kW-battery-converter-RevD-16Feb2016.pdf Best regards, Lloyd Sunstruck Consulting Sent from Mail

Re: [RE-wrenches] Trend away from roof flashings???

This was brought up in a previous thread possibly years ago, but we can't use Geocel 4500 in at least one jurisdiction here because it lacks ASTM testing to some required standards that the AHJ is looking for. I can't remember if that was D4586 or C920. I confirmed with Geocel at the time that the

Re: [RE-wrenches] Trend away from roof flashings???

We use Quick Mount PV L-Mount but we're switching to IronRidge FlashVue soon. I've seen too many non-flashed solar pool heating mounts work their way loose to trust a mount without a flashing. While PV mounts are different and arguably better, I still prefer a fully flashed method. That said, I tr

Re: [RE-wrenches] Trend away from roof flashings???

OK, I'll stick my neck out.  We've done very few flashings on comp for the last 18 years or so, using (first) the highest quality polyurethane caulk we could find.  However, for the last 10 years we've been using Geocell 4500 which states on the tube that it is compatible with asphalt/comp shin

[RE-wrenches] Trend away from roof flashings???

I’m interested in what the group has to say about the trend, by the racking manufacturers, away from the use of flashings for asphalt/comp roofs? We have long used SnapNRack flashings with much success. I especially like the fact that the penetrations are fully flashed and do not rely on seala

Re: [RE-wrenches] seeking 3ph battery based/backed inverters and experiences

I know Schneider has a way for that Jay. I just took XWpro webinar yesterday. Maybe a transformer was used for 480v but clusters up to around 40 KW. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1] e-mail offgridso...@sti.net [2] text 209 813

Hi Christopher I’m not sure what power your looking for. Try https://www.princetonelec.com/dela-inverter There are others too None of the normal ( OB, Schneider etc) will do 208-480. Only 120-208 Jay > On Apr 20, 2021, at 4:15 PM, Chris Schaefer wrote: > >  > G'day All, > > I'm not fam
