Grecell 2,000W - Excellent Product / Great Value
I received my first Grecell 2,000 Watt Power Station in early January of 2023, and I now own a total of three. I’ve done quite a bit of testing since then, mostly regarding total AC output power, recharging time, and connecting to solar, and my overall impression so far is this is an outstanding product at a very competitive price.
Pros and things I like:
1. The packaging of the product is absolutely first class. Double, heavy duty corrugated boxes that fit perfectly inside one another, and the unit itself is completely surrounded by pliable foam.
2. As advertised, it’s a total off-grid energy package, including an MPPT Charge Controller and an adapter for standard solar (MC4) connectors. I believe this is not the case with some of the competition, probably because they want to steer you towards buying their own proprietary and more expensive panels. Be that as it may, I purchased a standard 425watt LG panel with MC4 connectors, which I had to locate almost 100’ from the house, but it works like a charm (using 10AWG wire). Delivers slightly over 425 watts in bright sunshine (according to the Grecell LCD readout), and I am so far very impressed with how well the system manages simultaneous “power in” and “power out”. I can run a full size refrigerator/freezer even on a partly cloudy day, and still increase the battery state of charge by at least 10 percent per hour on average.
3. I can also confirm “full recharge” time of less than two hours on AC wall power. After complete discharge, I’m able to fully recharge in just under one and hour–forty five minutes. Obviously a huge plus if grid goes down.
Each of my units are able to support the items I want them to power in such an event (fridges, freezers, furnace, etc) for at least 12 to 14 hours - so worst case scenario would be having to run the generator for maybe a couple of hours a day for recharging. And if it’s a sunny day following a night without power, probably a whole lot less than that.
4. The cooling fans are extremely quiet, and seldom even run unless you’re re-charging with AC wall power.
5. With regard to total output power of roughly 2,000 watt hours: After some initial testing, I was at first somewhat skeptical of this “advertised” total power, or even 85 percent of that (1,700Wh), which as their “product information” explains is a more reasonable expectation. I ran several different loads until the battery was completed depleted, including - (i) A single full size refrigerator/Freezer, and (ii) a combination of multiple chest freezers along with my gas furnace – and based on using two different watt-meters from two different manufacturers, I was only able to get around 1,400 to 1,500 total watt hours delivered, over some 14 to 17 hours. Realizing, however, that the Grecell unit itself is burning some power just to operate, and the longer the run-time the greater the loss, which is not being seen by my meters, I decided to run a space heater pulling a steady 1,230 watts for only an hour and twenty minutes, and bingo! One meter registered total accumulated output watts of 1,710, and the other 1,752. So bottom line, as far as I can tell, all advertised specs appear to be spot on.
There really aren’t any “cons” that I’ve found so far, and the only thing I don’t like, strictly based on my own application and where I needed to place these units, are the charging inputs and AC outlets being located on either side of the unit. These along with “flip up doors” to protect them, created an access/interference problem for me, and I had to modify quite a bit of my existing shelving and install “drawer slides” for each of the units. Not a deal breaker, but a nuisance for me personally, and I would have much preferred all of these inlets and outlets being located on the face of the unit.
Something worthy to note in conclusion, is that it really pays to shop this product. I found various prices from different sellers over the course of just several days that varied as much as four hundred dollars. I would up paying on average just a bit over $1,000 for each of my three units, and as far as I’m concerned, a tremendous value at any price even close to that based on pricing I’ve seen from some of the competition for units with similar power. Hopefully, all three of my units will continue to perform as well over time.

My locos are once again running smoothly!
Have only used it twice but so far seems to work perfectly. Good price and quick delivery - couldn't he happier!
