Great product. Easy to install. BUT just because you buy a kit, that does not mean you will have everything you need for the installation. My kit only came with half the cable necessary to connect the panels to the box.......those are extra!

Hi Jay,
Thanks for the feedback! I'm sorry the cables included in the kit weren't long enough to reach your combiner box. We do our best to size the kits based on the average install - sometimes our customers setups are outside the norm and longer cables are needed. We're sorry if we missed that information when you ordered, but we're more than happy to help you find what you need!

The Delta 2 ecoflow along with the added battery does a great job. Easy to use and pretty self explanatory. Everything is set up and ready to go, gou g to plug in our fridge and test it to see how long it will run on a full charge. I've had the Delta 1800 for a while so it's gotten some use, really delivers. Ran lights set up around camping site as well as charging phones and tablets easily lasted all three days. Charged it back up when we returned home still had 29% left. In summery we're very impressed and feel that we made the right choice after all the research we did looking for a solar setup.

Fast Charging Lightweight Potential

So far so good with this little thing. I have mostly used this unit to charge three to four small-demand items at a time: phones, laptops, fans, lamps, etc. which sum roughly to a 200-300 W total demand for short periods of a few hrs.

The AC input charges very quickly (more or less as advertised), but I have yet to test solar charging via the 200 W briefcase panels I bought (200 W monocrystalline from Rich Solar).

The interface appears simple to use and interpret, although not as elegant as the touch screen on my Bluetti AC200P. The app functions very well and the unit is light enough to be considered truly portable (I measured it around 26 lbs).

Unfortunately, when pushed a bit, the fans are flat out noisy (north of ~900 W input or output). This is not a deal breaker and understandable to a degree, but nevertheless the reason for 4/5 stars.

I've watched a review that measured the fans at 65 decibels (at full 1200 to ~900 W AC charge), which is described as a normal conversation to hair dryer type noise. I would describe the noise as closer toward the small hair dryer level.

Again, this is not the end of the world, but it does effect how much wattage I want going in or coming out - while indoors, especially in a small room (this would be a bit noisy in a van or small RV). When fastest possible charging is not necessary, I recommend adjusting the max AC input to roughly 700-800 W, which seems to keep the fans less excited.

I look forward to testing the unit more…
