[RE-wrenches] Strategies for staged startup of appliances

In an off-grid situation I'm looking for a strategy to manage transfer from generator power to inverter power because I have a lot of high startup load appliances planned for a system. Think 8 mini-refrigerators, one sub-z large refrigerator, and an under-cabinet ice maker, not to mention air condi

Put the loads on contractors, control the contractors with adjustable time delay relays. Stagger the timing. > On Sep 11, 2019, at 2:41 PM, Jason Szumlanski > wrote: > > In an off-grid situation I'm looking for a strategy to manage transfer from > generator power to inverter power because I h

Re: [RE-wrenches] Strategies for staged startup of appliances

That is what I was thinking, but how will the contactor coils "know" when the ATS switches to inverter power. I'm thinking I need to use an AUX relay or a series of relays to produce the desired result. I don't think it will be necessary when going from solar to generator in this case, but maybe. I

[RE-wrenches] Digital Refractometers

Hi William, The old school optical (analog) version is too time consuming for your needs? If not Misco makes two models oC or oF The oF model is 7084VP. The actual manufacturing of the unit is done by Reichert. Reichert makes multiple digital refractometers, hopefully of the same quality as the Mis

Hi Jason, I would use soft start on everything that I can. The mini-split already is soft start. There is a device that adds soft start to appliances/loads below. https://www.raymondinnovations.com/ [1] In the future Schneider and I assume Outback will have API's for their electronics. Sch

Re: [RE-wrenches] Strategies for staged startup of appliances

You’ve got to plan on them all starting at once anyway. You can’t expect that it’ll never happen. And really how do you prevent it. The refrigerators and AC’s are on all the time waiting for the thermostat to activate. And it’s not good to turn a working fridge on/off especially is the compre

Jason, You may want XW pro. It is not much more than XW+ and will have a better support for what you want in your microgrid. It also has twice the warranty over xw+. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1] e-mail offgridso...@sti.net [2

[RE-wrenches] LiFePO Failure modes.

Has anyone had any problems with any of the popular Lithium Ferro Phosphate batteries other than getting the voltage settings right. Just now cleaning up the mess of 3 customers finding their Aquion batteries failing and having to replace them. I have installed two systems with Simpliphi and one
