How To: Two Delta Pros with Transfer Switch
We went for weeks without power post Hurricane Helene last year and since then I have been looking for a solution. We rarely lose power and then usually only for a few hours, but I want to be more prepared for longer outages. I only need to back up critical circuits. We are fine without HVAC or washer/dryer or even a stove. Necessities include the main refrigerator, a dorm fridge, 1/3hp sump pump, (which never actually runs, but I would want it powered just in case,) and the circulator for my natural gas boiler, (just in case we have an outage in winter.) Probably a TV, wifi, and a handful of lights, and that's about it, really. I have purchased two Delta Pros and the Double Voltage Hub to give me 240V and more output. I don't necessarily need 240V. I want to get a manual transfer switch for simplicity for my wife, and others. I know an interlock kit is less involved to install, but I like the simplicity of having my necessary circuits in a subpanel. But maybe I'm wrong about that idea. Also, I don't have any solar at the moment but think I will probably do a small array if only to charge/power the Delta Pros. I know I can't power much for days but I also have a small Honda 2000i gas genny that can be used to charge the Delta Pros, as well as an EV sitting in the driveway with a 65 kWh battery in it that offers vehicle to load @110V. So I have ways to charge if an outage goes on for a day or three. So, interlock kit or manual transfer switch? Can you recommend a transfer switch? I guess it's gonna be a 30amp? I might get by with 6 circuits as long as a couple of them are 20amp. Or I could go with a 10 circuit transfer switch. Can you charge the Delta Pros while they're powering devices in the house? What am I missing?
