Will - I'm very much looking forward to your complete test and review of the DELTA. I know there are a couple units already out for 'testing and review'. Here is one: https://www.youtube.com/watch?v=q4oJOAreLCc I know your test and review will be much more comprehensive than this guy, I...

Hey guys, I just received my unit early this week, a little later than some others. Yes it has the same issue however I'm still very happy with the DELTA. The issue is that the 'larger' slot is on the right whereas if you look at a normal US outlet, the 'larger' slot is on the left. This...

I have Zero affiliation with EcoFlow. I'm just a guy interested in Solar PV, batteries and related tech. I thought the DELTA looked like a great unit compared to others out there so I bought one on the earlybird kickstarter and wanted to start some discussion with this thread. Will - Thanks...

Interesting unit. And Expensive. Since you want to compare this to the EcoFlow DELTA I will dive into that. However it should be noted that the Titan is kind of the next class size up as it is designed to be used with (2) of their battery packs. I will compare a 'base' unit with one battery...

Excellent PV module, one of the best on the market and my personal favorite. They are 96 cell modules which is why they are so high voltage. Unfortunately you need to look at the VOC times a safety factor of 1.25. So 69.7 VOC * 1.25 = 87.125 V. I would not use any solar input rated for less...

Here is a re-post of the current info on the DELTA from the old thread so we can continue discussion. EcoFlow DELTA - Kickstarter Page This is a newer company (2016) although they have already produced a successful smaller product called the 'River' sold at Home Depot, Best Buy and Amazon...

DELTA Solar Panel Sizing Most PV inverters and charge controllers that I'm aware of do not have any Over-Voltage protection on the PV input. Meaning if you put too much voltage in, you will fry your unit. Amps are easy to use an inline breaker or fuse typically. Something else to be aware of...

Another testing video just popped up on youtube. He uses a variety of shop tools on the unit. Solar Power Welding With the resistive load of the Mig welder, he was pulling 2,000W - 2,500W from the DELTA. I don't think it could sustain that though for the duration of 30 min, as it was not...

Glad to hear some more backers posting thoughts. I'm looking forward to December so I can play around with my DELTA. In regards to the grounded AC outlets. This image was taken directly from EcoFlow's video of the DELTA charging up the Tesla model 3: It looks to me like there is a hole for...

Jehu also did a recent full comprehensive review: He praises the battery thermal protection stating this is very difficult to recreate in a DIY setup. In regards to the efficiency of the unit that has been discussed: "This unit has a round-trip efficiency of 63%. Now that figure is not...

8 days left before the kickstarter is over. EcoFlow DELTA - Kickstarter Page If you have been thinking about it, you still have time to grab one with the discount price, Lifetime battery warranty and extra stretch goal goodies. They just announced a new stretch goal: an Uninterruptible...

mxp - Two of them would be too much voltage, max input is 65V. One would work just fine though. SunEdison 335W 72 cell Mono Short Circuit Current (ISC) : 9.29A Open Circuit Voltage (VOC) : 46.4V 46.4 VOC * 1.25 (safety) = 58V

gnubie - Are you talking about the International Version?

mxp - Absolutely, happy to help. I think the (2) Rich Solar 190 watt modules in series is probably the best option. As I mentioned, I don't even know where I can buy those other 2 options right now. Connecting panels in series on the higher end of the Voltage limit is the best way to do it...

I think Renogy would likely be a fine choice. They are probably on the same quality level as Rich Solar. As you show in the above calculation the (2) 160s in series would be well below the 65V input limit. Personally between the two I would choose the (2) Rich Solar 190s just for more power...
