I am on the grid and have a 5.6kW solar system with AC sent from all panels (all have micro-inverters) through a controller switch and on to either home use or to grid if over production. Combined output is 240VAC at 21amp.I want to add the necessary Eco product(s) to address two goals: 1) provide backup power for priority home circuits if/when the grid power goes out, and 2) connect a battery/controller system where the battery gets charged up daily from my solar over-production (i.e. sunny days) and then use the battery+grid at night for home use. What do I need for this set-up?

I have two banks of Ultra Pro inverters with 3 (6000KWH) - (18,000kwh) batteries each and two smart panels II to power my whole home. I would eventually like to go off grid in the future. I have no solar panel feeds at this point, but I assume at some point I will. My generator is hooked up at the Gen In on both panels but it is manual. Can Eco Flow Engineers provide an output signal (analog - 4-20 mA or digital - 5-30Vdc) when the batteries are at 10%. This output signal can be fed to a smart circuit to automatically turn on my generator. Likewise, when the batteries are charged at 95% the generator would shut down. I cannot understand why Eco Flow didn't give their flagship product the same option as their lower priced Delta product. Otherwise I am happy with the product, but it is frustrating that I have not found any help to solve this problem. Thank you to anyone that can help. I would be willing to pay for a solution.

I’m currently in the process of installing the SHP2. I noticed on the manual that there is a 20m (~65 ft) max distance requirement between the SHP2 and the battery connection box. My current layout will require the distance between the panel and battery connection box to be around 80 ft. Does anyone have any personal experience with a setup exceeding this distance requirement? What kind of issues will this cause if I exceed this requirement by 15 ft. Any insights will be great!

PROBLEMThe mobile app - despite being "compatible" with tablets, doesn't appear to scale for them properly.An iPad Mini looks fine. Don't use mobile phone but based on the UI I see, assume it works fine. But on a Samsung Galaxy A9, which is about as standard as you can get for a tablet in terms of size, everything is too blown up to be useful. Also, this is a landscape tablet, and apparently there was no desire to actually program a landscape interface as with the Ecobee and other truly "smart" devices.Photo attached as an example. There are eight devices; you can only see four of them. The only way around this is to tell the tablet to support 16:9 mode; then you get some rescaling buttons, but they don't work for each device's energy view, only the main "Space" page.Ultimately what's missing - and it's a simple thing - is to query the device for its resolution, then scale accordingly. That's what apparently has been done on Apple; have not yet tested with a regular iPad, but I will, because for the specific use case it fortunately doesn't matter if it's an iPad or an Android.QUESTIONDoes Ecoflow plan to actually modernize this app?Having a non-dark mode would also be nice - I know the "techie" folks love it, but it's hard on the eyes when your eyesight isn't the greatest trying to read small text.

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?

Ac inverters will not run if DP3 is unplugged from the wall socket.Brand new, received yesterday.Worked fine yesterday, used app to Turn off AC outlets before bed woke up this morning and inverters would no longer operate unless the unit was plugged into the AC wall current. Will not operate as A UPS.

Where are the Maximum Circuit Settings on the Smart Panel 2 app AFTER commissioning?

I want to add battery backup to my existing solar panel setup. Is the DELTA PRO ULTRA INVERTER plus backup battery plus the SMART PANEL 2 all i need to complete the battery storage installation.

We live in a rural area of Northern California. We have very hot, dry summers and severe wildfire hazard. We experience periodic power shutoffs throughout the year, but primarily during fire season. These shutoffs are typically 6-12 hours in duration. We currently own a 6500 Watt Generac gas powered generator that we use during shutoffs. With it we string power cords to 2 refrigerators, TV, router, lights. But we haven't the capacity (or connectibility) to power our (1 hp) water well pump or HVAC unit. We rely of electric power for our AC. The HVAC system uses propane for heat and electricity to power the fan that moves the heat. So, if the shut-off occurs during the 110 degree heat, (or a cold spell) it can be unbearable, and water is unavailale for domestic use or plant/lawn irrigation, or even fire suppression.We'd like to have a battery system that could be installed to power our entire house for up to a day. I think a manual switch would suffice for utilizing the battery power, so long as there's a way to determine when utility power is restored. Also, would like the ability to charge the battery during off-peak hours and then utilize the battery to power our home during peak power cost hours. Also, if necessary, we could utilize our generator to recharge the battery if power shut-off extended for multiple days. Don't care to clutter our yard or roof with solar panels. I recently got notice that our utility provider (Pacific Gas and Electric) is providing some rebates for battery backup power units. So, now might be an appropriate time to acquire a battery system. Looking for advice here, since I'm quite unfamiliar with the entire subject. Thanks in advance for any input!

I have been advised to do a 100% drawdown 3 times in a row and then a hard restart. This is in an effort to recalibrate my Delta Pro Ultra. I also understand discharging greater than 80% can lead to damage and longevity of my battery. Should I do the 100% drawdown 3 times?

Good day. I'm currently employing a Delta Pro Ultra with two batteries and 10 X 100 W (12v) panels. I am considering adding a windmill to supplement my solar stream. Will I encounter any unforeseen issues if I plug it in my solar input stream. Be well.

In order to have clear coverage for my solar panels (away from home and trees), I would need to have them setup about 90 feet from the Delta Pro 3 unit. Any suggests on where to buy a 100' extension cable and is it even feasible to have them that far away? Thank you!

I have a River 2 Pro for CPAP backup. It has kicked in for minor outages and been fine. I do not know if it will cover the whole night though, as I use the humidifier and heated air line with my AirSense 10. When your system kept your CPAP going all night, was that with heated airline and humidifier running?

I have a Delta Pro Ultra, and I'm looking at 120V portable inverter generators (3500W-4500W) that have both 20A and 30A outlets. My question is if you want to charge a DPU while it is supplying power to the house, is there any benefit to charging through the 30A port #19 (using the EF adapter cable) rather than using the 20A outlet port #15? I seen suggestions that charging through the 30A port will allow charging at up to about 3000W, while charging from the 20A outlet is limited to 1800W, but they all have referred to charging through #19 at 240V. The “suitcase” size portable generators I’ve been looking at, weighing around 50 pounds, are all 120V only. I'm only looking to increase how long the DPU can support my service needs if an outage is extended.

I'm new to the EcoFlow ecosystem and currently using the DELTA Pro 3 to power a single office circuit while charging from AC. I’ve noticed that while the app allows setting an AC charging limit, the unit still draws additional power to support passthrough loads—resulting in total AC draw exceeding the configured ceiling.This is a serious concern on a 15A circuit, where exceeding the limit risks tripping the breaker—or worse. While an electrician was installing a house-level Smart Panel 2 (which includes this circuit), they observed that the panel wiring was running warm—clear evidence of sustained overdraw and a potential safety hazard.My goal is to power the office via the DELTA Pro 3, with energy supplemented by both solar and AC input. Since solar won’t always provide enough, I need to ensure the system never exceeds the safe draw from the AC circuit. The room generally runs between 900–1450W, but has occasionally exceeded that—I’m currently using an extension cable to offload some devices to another room (not ideal).What I’m looking for is a way to set a maximum power budget of around 1100–1200W, so that when the room is under that threshold, the EcoFlow can “top up” the battery via AC. But when the load increases, the unit should automatically use the battery to supplement operation to avoid exceeding the circuit’s capacity, I can partially, do this by using "self-powered" which works for solar top-up, right up until it goes below the reserve limit at which point it starts pulling excessive power from the wall...Ideally, this would be a firmware-level feature that enforces a hard limit on total AC input, regardless of whether the unit is charging or powering a device. If anyone has found a reliable solution—hardware, automation, or configuration—or knows if EcoFlow plans to support this natively, I’d appreciate the insight.The Delta Pro Ultra has this for "generator" input where you can set the maximum input from the generator, so why not also for A/C input?

Hello all, Happy to be here, hoping for some wisdom. My DeltaPro3 is charged to 80%. It is currently unplugged and OFF. Yet it is intermittently beeping, usually a string of 4 beeps at about 5-10 second intervals. This may happen several times in fairly close succession (over an hour, say), and then it may not happen for several days. Then it perks up and beeps again, and believe me, it's got my attention. It seems to beep more often at night, I'm sorry to say, which can be startling. I've read what I can and tried various things such as long-holding the power switch, etc., but so far, no joy. Hints, pro-tips, or shared experiences? It does work well when I power it up to discharge a bit, and if I leave it plugged in and sleeping it will maintain that charge level, taking a sip from the wall plug now and again. But ... on or off, full or not, it beeps. So strange.

Hi, everyone. I’m one of those many people who misunderstood net metering and invested in 33 (410 watt) panels with no batteries. Now I’m considering starting with the scaleable system of a single DPU one battery and the smart panel two. Here’s my question… if the PV input capacity is 5K and I’m producing 13K what happens to the extra power produced by the Solar array? (I hope I’m asking this correctly) can someone help me better understand? Thanks.

Looking for an EF setup to use as an office UPS for a couple laptops, on desktop and small TV. Would need to be able to maintain power for a short period of time (ie 1-4 hours). I have a Delta Pro 2, but use it in other areas, would like something dedicated to the home office. Was looking at the River unit.

Hello fellow EcoFlow fans! I have a Delta 2 with Extra battery. I have it hooked up to 500W solar panels. My EF powers my WiFi router and few low wattage lamps at all times. These will stay up even when the power goes out. So my power station makes some power and uses some power every day. Rarely is it completely discharged, usually doesn't go under 90%. Wondering how this effects the charge/discharge numbers? Does each day of small input/output count towards the total 3000 charge/discharge life span?

How does one safely add a new Ultra battery to a short, working DPU stack that is already connected to a Panel 2? IF the instructions are in the manual, then I've missed it...twice...
