We’ve upgraded our Rv in 2021 to a 5fr 42’ alpine 37kb ft living room it has two 15000 btu ac’s a residential refrigerator so I started adding solar and lithium batteries. The best thing I did was purchased the Ecoflow delta pro. Made some changes so I could hook up for off grid. Now I have two extra batteries, solar panel, delta max, rivers (4 of them). We used last season just had one extra battery and did a lot of non electric camping and was never short of power. Now we didn’t use the AC but had all the power we need. We’re looking forward to using the new system next month. Great stuff Ecoflow thanks!
I bought the system back in the Kickstarter days. Two Delta Pros, One Smart Extra Battery, 400W Solar Panel, One Extra Infinity Cable, and the Double Voltage Hub. Shipping delays, FedEx, and a DOA Smart Extra Battery created a few concerns. That said, customer support was very good. Responsive when you contact them and quick to resolve shipping and repair of the Smart Battery. Installation of the system went well after finding a competent Electrician in the area. Startup of the Smart Home Panel went reasonably well after multiple firmware updates. Initial scheduling of Charge and Discharge functions take some time. It is a bit clumsy and does seem to take a few days to incorporate the schedules. After the first week of actual operation I am very happy with the systems performance. The portability was the key to taking this approach to battery backup. I look forward to expanding the system in the future.
Good bye to my old, noisy, clumsy, fume-spewing, gas-guzzling generator. My ECHO Flow Delta Pro system is wonderful! It's quiet, portable, efficient, easy and QUICK to charge, and it looks good too! I've had to use it twice already due to scheduled power outages and it worked like a charm! I recently recieved my ECHO Flow Smart Home Panel, (although delivery was delayed due to the pandemic and supply chain issues...) as well as links to find electricians in my area who are qualified Smart Panel installers. Great customer service, excellent communication regarding delays and delivery schedule. All in all a wonderful experience! So now, Instead of buying a generator for an RV I don't own yet, I'm considering purchasing an RV for my new generator! Highly Recommended!!!
I purchased my first DELTA Pro Power Station in April 2022. I was so impressed with the unit, I immediately ordered a second Power Station. The remote control is excellent and the interface with the EcoFlow phone app makes the system easy to customize. Best of all, any questions I have asked were promptly answered by the EcoFlow support team, great job EcoFlow. I recently purchased the first of two DELTA Pro Extra Batteries. Anxious for the Smart Home panel to be back in stock to complete my ecosystem.
My Friends are all wanting one now. I ordered my Delta Pro from Kickstarter last year, arrived just before maple syrup season. So this year I loaned it to the sugar shack which normally runs on a gas generator for a couple weeks. Needless to say the lights stayed on, the sap kept running and the tunes kept going with no back ground engines. Received 4L of delicious maple syrup as a thank you, plus the good times boiling! I also farm so this unit has been priceless for repairs and barn Reno’s where I don’t have hydro service. Now I can use my larger power tool like they are cordless. Cut off saw, table saw, air compressor, even 110v mig welder can travel where ever my truck does. And charge cordless batteries, and phones and keep the music flowing all day long. Keeps LED lights going for days without needing a recharge. Priceless for some with stuff to do!
