EcoFlow DELTA Pro Solar Generator (PV400W)

After more than two months' experience with our Delta Pro and 400W solar panel, we are very grateful to have purchased the combo. The solar panel, in particular, offers very impressive efficiency; we have been able to "refill" our Delta Pro from 70% up to 100% in a morning session of charging. The Delta Pro capacity is particularly useful when Eskom takes us to level 6 load-shedding, when we have been able to power our refrigerator overnight without a thought (it places a maximum load of 90W on the inverter when the compressor is running). I can power my research workstation for a twelve-hour compute session at full load without worry. We have begun shifting toward powering our laptops via USB-C rather than AC plugs when possible to avoid turning on the inverter. I would point to some minor criticisms: 1) Our Delta Pro came with Type G / USA combo AC plugs rather than ZA plugs; we compensated by purchasing a ZA plug adapter with fuse to accommodate our refrigerator. 2) Our Delta Pro came with an American charging cable; we substituted a heavy-duty ZA cable with standard kettle plug. 3) The firmware installed on our Delta Pro was pretty old, preventing me from connecting my phone via Bluetooth; we were able to update it by connecting the Delta Pro to our home wifi.

Very wel

So far so good! I ran a deep freeze and a water pump for a few days with just the solar panel for recharge. When there were no clouds, the input was more than the output. I plan on running my office with the Delta Pro and have installed a lockout and 30 amp plug on my breaker panel for emergencies. If a problem arises, I will post again. God Bless!

Great but not enough power runs out and can’t power small air conditioner

System works as described. Solid. Heavy (very). Panels are great quality. Heavy. Wish they had a better/easier way to angle the panels. Using the panel cover is a little wonky. The panels don't stay completely flat when you angle them because of the folding joints. Learned that 800 W of panels doesn't mean you will get that. Happy to get 680. Angle with sun is critical for optimum power generation but impossible to continuously achieve without the ridiculously expensive holder that automatically rotates and follows the sun. Still love the system.
