HI Dave and Chris, Good points, however. I’ve had radian board failures which shut it all down. You are correct if a power module goes down then it will still continue working. This project doesn’t need telecomm redundancy but close. And if the inverter shuts down then the AGS won’t

I think so also for the same reason Chris! So I guess I don't understand why you need the external transfer switch Jay? Is not the internal radian transfer switch the less is more for offgrid? --Dave > I think Radians are redundant anyway, if you parallel the output they will > keep going when

Hi Jay, I've been using the ASCO Series 185 for years with the Radian, single or dual. With some fine tuning I've gotten the transfer time down to around 1 second. The have a manual switch built inside of it. They also offer a service rated (with CB) or not. Zero failures to date. Christopher

I think Radians are redundant anyway, if you parallel the output they will keep going when one fails. Also, the 8KW are two x 4KW modules, both can function independently. I know this because we lost one at home and kept going until a replacement arrived. On Thu, Jan 11, 2018 at 7:03 PM, jay

[RE-wrenches] automatic transfer switch

2018-01-11 Thread jay
HI all, I’m doing a project with 2 radians in a redundant configuration. Each one would go into a transfer switch to power the common load. I’m looking for a good, fast transfer switch. 30amp 120/240 is fine. And maybe a mechanical feature as well. Code isn’t an issue Will be off grid, remote
