Pros

They have wheels and a telescoping handle like luggage. The battery itself is a feat of engineering and manufacturing.

Delta pro extra battery has lifpo4 battery that lasts for 3500 cycles to 80% capacity and 6,500 cycles to 50% capacity. It also varies the speed dependent on temperature and output. These have numerous configuration possibilities that should meet most... Read More

Ecoflow pro has the coveted 2000/2000 combo (2000 watts and 2000wh) the generator is controllable in the app and talks with the solar generator. It's a great standby power source of standby power, and it's fantastic that it will accept power from the ... Read More

The ef panels work exceptionally well. The rugged exterior and cables down to the quality of the lcd screen it's all very well built. I love that the panels fold up flat, and have a sturdy zippered case for storage.

The intelligence to include a lower charge shut off and an upper charge shutoff tells me that they really considered the lifecycle of your investment. I think this will be sufficient for my needs in an outage-although i am considering possibly purchas... Read More

Cons

Federal law says you cannot reuse a shipping container that has been used to ship battery packs. The dvh is a very chinese run company, but their tech support is non existent.

Ecoflow is useless without a solar input. I reset the dvh and it continued to trip, but only when the solar input got over 600 watts (solar panels specs were well within the parameters) arranging these to set up in series or parallel is very difficult... Read More

We lost power yesterday and i plugged my sump pump and freezer into the unit for several hours and very little battery storage was used.

Price

Instead, through the manual transfer switch, i am able to supplement my home electrical with approximately 7kw per day which sa... Read More

It was well worth the money and is a real life saver.

I'd even pay extra for it if it were available as an accessory.

Btw, i found the 400w solar panels for about $180 each so that cost will be made up in just a matter of months instead of years... Read More

Shipping

It arrived early in the five day delivery window.

I was also surprised that i had them within 5 days of my order so great job on the responsiveness to the company on my order.

Packaging/appearance

Received it with no damage to the packaging or the generator itself… charged it up in a lil more than an hour

Competitiveness

In addition to this, i have four 400w solar panels connected full time to my delta pro to help keep down my energy costs.

I found another electrical company in nashville, tn, five star electric, and they unhooked the smart home panel and connected m... Read More

I did go with a separate brand of solar panels for more energy input.
