Re: [RE-wrenches] 70-100 amp relay

Hi guys It’s for a 240vac relay between the generator and inverter so I can do warm up /cool down. It’s a 15kw generator derates to about 10-12 so 60-75 amps is all I am looking for. I’ll put it into a box of some sort. Thx Jay > On Oct 3, 2023, at 3:47 PM, Starlight via RE-wrenc

Re: [RE-wrenches] GT w/ BB

If 40kw is the peak and then there are new added loads, what 50-60kw?  If it was me I’d be designing the inverters to handle the 50/60 kw with future expansion capabilities beyond that. Then how much kWh of storage are you going to need or maybe are planning for?At some point maybe looking at a lar

Re: [RE-wrenches] sol ark AGS question

As I’ve been researching this, the Atkinson GSCM can do this when coupled to an external relay. If I understand correctly. Jay The warm up ( on delay ) is 0- 60 seconds, the cool down ( off delay) is 0-120 seconds https://thesolarstore.com/manuals/GSCM.pdf > On Sep 16, 2023, at 9:20

Given that it worked fine for years it would appear that the XW+ has an issue. I don’t see how the SE could cause this. Is it still under warranty? What does Schneider say about the issue. JayOn Jul 22, 2023, at 10:33 PM, Howie Michaelson via RE-wrenches wrote:Michael, that is my last ditch choic
