Features
- One Powers All. The unit of DELTA Pro Ultra whole house generator includes an inverter and a battery. One inverter supports 120V & 240V and has an exceptional 7200W output, allowing you to run almost any heavy household appliance, even a 3-ton central air conditioner. Triple the inverters for an incredible 21.6kW AC output, allowing you to live life to the fullest even during an outage. The electric generator achieves a total 7200W output even during charging.
- Strong Power Security. Scalable from one battery of 6144Wh, two days of essential power, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard North American household, that's over 30 days of essential power secured.
- Multi Ways to Charge. One battery of 6144Wh can be fully recharged in 2 hours. Faster than any other 6kWh solar generator. Users can choose among electric vehicle piles, solar, wall outlets or outdoor generators for charging.
- Light and Durable. The 400W Solar Panel is foldable and comes with an adjustable carry case. Weighing in at only 16kg (35.3lbs), it can be easily packed up and carried with you, no matter where you go. It also comes with a IP68 Waterproof rating, meaning it is dust and water tight.
- Kindly remind that the inverter, battery and solar panels will be shipped in separate packages.

Style: DELTA Pro Ultra
This thing goes WAY beyond expectation! It automatically balances solar inputs and circuit outputs, charging the battery to peak and then shutting off the solar if you aren’t loading it with household circuits. If battery charge drops below your pre-set emergency battery storage level, it pulls electricity from the grid to fill in the gaps. You’re covered 24/7, one way or another. I’ve been eyeballing it and testing things and on a sunny summer day, overnight draws are replaced and the batteries topped off by noonish. Right now, my whole house is running through it with the exception of the A/C and the circuit that the unit is plugged into in order to draw grid power. I have more solar cells coming and a second battery, at which point I expect the electric company to start wondering why I’m selling them electricity but not buying any.

Style: DELTA Pro Ultra Battery
Our son is a huge ecoflow fan so he recommended for us to get the ecoflow delta pro ultra! He has an extra inverter so it turns out that all we needed to buy was the battery itself! It’s great since we got to save money instead of buying the whole system! The battery is very heavy but at 110lb or so we aren’t too old to move it quite yet! (In our 70s). Our son recommended us to use it to backup our refrigerator since we don’t yet have the smart panel installed so we can’t quite tie it into our home, and our HOA don’t allow for solar panels, but my son and I ran a test and this thing is running our refrigerator as we speak and it’s been two and half days! Still got around 7% left! It’s a game changer for retiree like myself because I travel a lot with my wife and often gone for weeks, so being able to back up my fridge for so long really gave me the peace of mind. I also own some rental property and to be able to power up a tenant’s home during an outage is also quite useful! Nothing make happier tenants than light and warmth. Lastly, my beautiful grandkids love to play with this big instrument. My naughty son even shove his sister away just so he can play with it. She keep saying “sheer!” I think she wants to play too.

Style: DELTA Pro Ultra+Extra Battery
Was delivered on time and was easy to assemble. Charged great, but did not include the 30 amp RV plug and 30 amp wall connection. Had to purchase separately.

Style: DELTA Pro Ultra+Extra Battery
Bought this with 2 batteries for vanlife. Got it on sale and used prime card for more savings. Works as expected, runs my window AC, air fryer and everything else fine. The only issue is that charging from an EV charger never reaches 7200w. It only goes up to 6100w. An extra 1200w would be nice, thats 10% of extra charge (since i have 2 batteries) per hour. Update: Been a few months now so... 1. The charge controller makes a clicking sound when it detects power from solar panels, not loud or obnoxious but something to consider i guess? It clicks on/off in the mornings and evenings due to low solar irradiation. 2. The battery level indicator is only accurate for a few days. I think the batteries have to be charged to 100% once in a while to keep it accurate. I currently have it set to max discharge 5% and max charge 95%. The amount of power I use from an EV charger and the percent on the display is off significantly, so when I notice that, i just charge it to full. 3. The LCD display is constantly turning off/on when power is being drawn or stops being drawn. I wish there was a way to permanently turn it off since I live in a van (soon a truck camper 😬) and the bright as light is annoying af. 4. The standby power consumption is consistent with some youtubers measurements. I'm estimating it to be 5-10% per day. That is a big deal for vanlife but the 2 mppts, AC and EV charging makes up for it. My next camper will probably have 1600-2000w worth of panels. I currently have 1040w which would be fine if I didnt run AC or electric heat but I spoil myself. 5. While driving, if your panels become shaded temporarily, the input will go to 0w before going back to normal. If you're in shade too long, say under a lengthy tunnel or bridge or a row of trees, the charge controller won't start charging immediately after you're back in the sun. It takes several minutes, I haven't timed it. This sucks. That's all I can think of for now, hope it helps. Update 2: I just realized the inverter spits out a ton of heat while charging. In my truck camper now and I find that it heats up the entire space really quickly. This might not be the best product for van/camper/rv living since the AC has to fight all the heat this thing produces. May be in the winter I'll have a different opinion...? Update 3: I noticed when charging, the battery % jumps from the mid 50% up to 70% or so. Kinda weird how it can be so innaccurate, even after the update that supposedly fixed the problem of it not displaying the correct battery level. Sometimes I feel like the battery % that's displayed is totally off...seems like a serious flaw when trying to run this on a small solar setup. When the battery level that's displayed is too low and it hits your max discharge level, you won't be able to use it even if you suspect the system is wrong. I'm thinking about selling this thing and going back to building my own system. 🤷 Update 4: Let the system drain to about 4% then charged it fully. It only charged ~8 KWh to get to 100%. Which means about 3500-4000Wh was left, likely in the second battery. The voltage reading must be off so that's probably why it thinks there's only 4% left. Such a disappointment.

Style: DELTA Pro Ultra Battery
I like the Ecoflow system because it is plug and play. I had an electrician install the Ecoflow subpanel. This is not strictly necessary but with it things are seemless during a power outage. Everything just keeps working with no lag. I currently have five of these batteries and one inverter. I can expand this whenever I can afford it one battery at a time. What I have right now is enough to run my A/C for 48 hrs or my furnace for five days. I would give it five stars but for the price. If you have the knowledge you can build your own system for about half the price.

Style: DELTA Pro Ultra+Smart Home Panel2
I love the Home Panel 2 & Deltra Pro Ultra design and the fact that battery backup is easily expandable, just add extra batteries into Delta Pro Ultra stack. The Home Panel 2 is much better looking and functional as compared to other smart panel solutions in the market. Best part is that you can any brand breakers and the panel can smartly control them. The trolley for Delta Pro Ultra has wheels to easily move it but has an option for fixed rubber pads too. The battery pack can easily be unplugged from home panel and can be used for parties in your backyard, carried in car for camping purpose etc. The casing of the batteries looks sleek but is also built pretty solid and durable. Moreover, the this Home battery backup solution qualifies for federal tax rebate of 30% too because each battery capacity is 3.6 kWh which is well above the 3 kWh qualification requirement.
