"Now You Know - Nothing Like Ecoflow"

I never had any reason to understood why my electric bill, until receiving for two months a bill over $400 dollars. After purchasing my first Ecoflow DELTA 2, then the following year a Ecoflow DELTA Pro things have changed. Learning the how (kWh) works from the local electric company, these Ecoflow batteries help me out a lot. When I checked my records up to the time of my first post (March to April). Running everything in my Livingroom for the (first test - month). It cut $20 dollars off my bill. In the second half of my test, the second month adding major appliance Refrigerator, from (April to May), also cutting cut out power spicks in the system. The average surge that happens throughout each day, the Ecoflow regulated kWh usage. That second month they cut $40 dollars off my bill.Now, I know this could be viewed as a small progress or achievements. Yet, these are smaller tests to a bigger change down the line. Which includes the house AC unit, furnace, attic fan, sump pump, and light throughout the house. Which I'm changing to LED lights because they use much less electricity than normal light bulbs. With the world today, going out of control with uncertainties. The average homeowner is faced with many things and having a Ecoflow battery as part of your Back-Up or Off-Grid power source, is more than just being smart. It's being responsible and reliant, its believing in a company that has your back taking care of your family.Now, for my famous words, "Now You Know - Nothing Like Ecoflow"

Fast Charging Is a Game Changer ⚡

One thing that really stands out on the EcoFlow DELTA series is how fast it recharges. You’re not waiting all day to use it again. Plug it in and it actually gets back up quickly, which makes it way more practical—especially if you’re using it regularly or during outages. That quick turnaround is what makes it feel usable, not just something you have sitting around.

Solar Panels for a Delta Pro Ultra

We have a Delta Pro Ultra with a single power unit and two batteries, purchased 2 400 watt solar panels to try to help recharge the system, system is at our hunting camp and not used everyday. Everything is hooked up and mounted, the panels are mounted flat to a southwest facing wall in upstate New York. Upon initial hook up we are not getting any input from the panels to the unit. Should we at least see some minimal input?We are going to angle the panels to 40 degrees and see if that helps. Anyone have any tips? Should we in-fact see any input readings with the panels mounted flat?

How to discharge ultra to 0% when connected to SP2

Was trying to recalibrate the Delta Pro Ultra batteries (2x) by discharging to 0% and charging to 100%. The Ultra is connected to SP2. The system will not let me change the backup reserve to below 10% in the app. Is there a way to do this without disconnecting the Ultra from the SP2? TIA.

Delta 2 Max with 2 extra batteries.

Powering an entire trailer with the EcoFlow Delta 2 Max and two extra batteries is a solid off-grid solution. With expanded capacity and high output, it can run essentials like a fridge, lights, fans, and small appliances for extended periods. Solar input keeps it recharged, making it practical for camping, travel, or outages—though heavy loads like air conditioning may require careful power management.

New to solar power

So we go to 10 to 12 Nascar races every season and just bought a travel trailer. So looking at getting the Delta 3 Ultra with 500 watt solar panel. Reason is since living in rural area and if you blow right during a storm power will go out and wife hates pulling out the big generator. So power station would be used at home and in travel trailer. But how hard is it to add multiple battery packs to unit? Also I am guessing I would have to get someone to come out and install a transfer switch for the house?

Some things on their way

Something new dropped today...the EcoFlow Delta 3 Max series bag. Not sure if I'll use it for the battery or as luggage. Snagged it instantly along with a few other new toys. The DPU long cable will complete my garage projector to separate the DPU inverter from the battery stack (helps with cooling), and the Rapid Desktop Charger will allow my Rapid Pro setups to accept fast charges. Got the newest Rapid as well.

New Additions to EcoFlow Official eBay

I have an unhealthy habit of following EcoFlow’s Official eBay Store. Particularly the certified refurbished section and noticed the “newest” appearances of the Delta 3 Ultra Plus, Delta 3 Max Plus, and the Delta Air. So if you’re in the market for these power stations, you cannot go wrong with certified refurbished. 😎

Low AC voltage output during brownout?

Hi, I have a Delta 2 Ecoflow. I am currently experiencing a brownout. I have about 90v on the mains. When the Ecoflow is plugged in to the mains, it ALSO puts out the same 90v on AC. When I unplug the the Ecoflow from the mains, the AC output jumps to 120 (but of course I am draining the battery and not recharging). Anybody know how to fix this? Thanks.

Ecoflow bundles

Just curious who has upgraded to a new panel with backup batteries and solar panels. Looking into the flagship bundles and the 2 battery bundle with the smart home panel 3. Its a savings to go with the flagship, but are 4 batteries needed and is the money better spent on solar panels.

Solar panels for delta pro

How many solar panels can I attach to a delta Pro 3. I currently have 2 x 220w but need at least another one to keep the battery charged. What other cable adapter do I need?

The perfect disguise, a competitor cover so no one will steal my EF

I got a Jackery power station cover on Amazon Vine, but of course, I have no Jackery stations so I fitted this over my EcoFlow. What a disguise...now no one will steal it because who wants a Jackery hahaha. EcoFlow is safe 😉 it actually engulfs the EF Delta 3 Max completely.

...lost one..

...I lost the content on my previous post...I posted it but it didn't show in the posted list...here's the one clip I saved where after I rinse the panels the production recovers for about 20 min...
