Yes… the Ecoflow Smart Home Panel 2 does just that. The panel has two major connection ports 1) for connection to the the utility grid and 2) for connection to a standby generator. The automatic start up of the standby generator, gas or diesel, depends on its manufacture and making sure that it has that function to start up. Once it does that Ecoflow Smart Home Panel 2 will automatically switch over to the standby generator or back to utility which ever you have selected. To find out more about the Ecoflow Smart Home Panel 2 go to this website, bit.ly/4aPDX77 Going to this website has special discounts as well as informative information. To find out more about the Ecoflow Smart Home Panel 2… click on “Product Series” then select Ecoflow Smart Home Panel 2…that page will give you a lot of information that will answer all of your questions about this product.

When the standby generator senses the loss of supply power from the Delta battery it will automatically start (if it has that option). The change-over switch on the home power 2 must be selected for the standby generator. The home will experience a momentary loss of power while this happens.

@pspt
@pspt 5 ай бұрын
The quick answer is yes absolutely. When connecting the smart home panel 2, the load wire connections can be made in the existing panel and the load breakers that were used can be left in place for a quick reconnect if there is trouble. Having said that, all of the breakers in the Smart Home Panel 2 can be manually switched just by toggling the breaker switches. If for some reason that doesn't work (due to a failed breaker etc.), there exists 2 relay switching knobs that can manually switch the main power.

A lot of physicists have produced KZbin videos in the last 2 years that have disputed the idea that the explanation of electrons pushing electrons along in the wire solves the apparent contradiction between the drift electron speed and the speed of light propagation of electric charge. They all seem to agree that it's the surface charge that is set up at the speed of light which is responsible for the electric forces creating the current.

I have this system on order and currently waiting for delivery. A question I have that's not been addressed to my satisfaction by EcoFlow support pertains to the 2 transfer switches located near the top of the panel on each phase. Are those mechanically coupled switches that actually change state when operated by hand? My reason for asking is if I move the most critical circuits for my home into this panel and there's a problem with those automated transfer switches, I would be without power for at least the circuits on that phase in the panel. EcoFlow support has told me if they fail their state cannot be changed by manually moving the switches suggesting they are just an electrical switch controlling a relay. Thanks

@pspt 6 ай бұрын
Hi Robert... The two breakers that you are talking about may be considered transfer switches although they are better described as double pole single throw breakers that bring energy from either the grid to your critical circuits or from another source such as a gas generator. There is one breaker for each supply. For safety reasons, these breakers cannot be switched on both at the same time. In order to prevent this from happening there is a mechanical slider that prevents both from being turned on at the same time but does allow one or the other to be switched on depending on whether you slide it up or down. When both breakers are in the off position the slider is free to move up or down allowing you to turn one or the other on but not both. I hope this answers your question. It is easier to explain if I was allowed to include graphics in this reply but I can only do that with direct mail.

Post your questions on Ecoflow Delta series on Facebook. There are many contributors that answer questions. If you do post a question, you should state your DPU/SHP2 issues with pictures if possible. The circuit breakers you are asking about are usually 100 amp (grid from main panel) 30 amp breaker for your inverter generator to charge the batteries and run your outlets at the same time. Hope this helps.

​@@hlm34 Thanks for the reply but I installed the DPU with a Reliance 10 circuit transfer switch instead and returned the SHP2. I didn't have confidence in the panel after reading several owner posts about relay failures. IMHO EF needed to incorporate a simple mechanical means of isolating the SHP2 in the event of a panel fault so one could still keep their critical circuits operating while waiting for parts or a panel replacement. I read a few stories of people waiting for replacement panels and then an expensive nightmare to retrofit.

@ I had my SHP2 installed by an electrician. Very costly, but it works as intended. Im never home when the power is out and that’s the reason I chose the SHP2. We’ve had 5 power outages since the July install. The only way my family knows there’s an outage is when the internet goes out. The SHP2 charges the batteries daily, the batteries are automatically charged if there’s a storm coming. The other reason is my family are not “hands on” when it comes to a manual panel. They would wait on me. The manual panel will be my next adventure when I retire in a few years, if not sooner. That FB group is good to join even if you have the manual panel. There isn’t much they can’t handle except returns and RMA’s.

They can be separate although the only zigzag transformers that I encountered were on the same core. That is they were a transformer bank not individual transformers.
