Voices from DELTA Pro Ultra Users
Brought a BMW ix home from work to test out ev charging from the dpu. It would be a lot more miles added if I had more capacity. But the dpu had zero issues charging at 7.2kw on the 240v outlet using a standard home ev charger level 2. Gained about 10 miles or so. In an emergency that could mean a lot. Can’t make gas at home but you can make electricity!

Loving the new setup with the EcoFlow DELTA Pro Ultra and Smart Home Panel 2. We are completely powering our little farm house off grid now (But it can switch back automatically if we need it). Running with 4000 watts of Ecoflow Solar panels. Can’t wait to get the second DELTA Pro Ultra in the mail this week and hopefully upgrade to more solar here soon to max out both units solar input.
