So, I just started putting it together but I'm impressed with the quality as I unboxed it. If anyone was interested in how it's delivered I made a quick video

 
You should probably build a 6" concrete pedestal to mount it on.
Over the years moisture from the soil is going to rust out the steel on the bottom.
EG4 calls the kitted out BossBox a "solar generator". It has the same footprint as a 22-24kW whole home Kohler or Generac generator, like the ones that you can buy from Home Depot.

I'll bring that up because, if you just don't want to deal with pouring your own slab, for $350 you can buy a precast concrete generator slab that fits perfectly. Also available at the big box home improvement stores.

My BossBox (and everything else) showed up yesterday.

Let us know how that pad does.

Are you planning to even out the ground underneath it so it settles? Seems a bit high spotted.
 
I leveled it after the video but it's still gravel.

I checked all the big box stores around me and no concrete generator slab in stock and I'm not wanting to wait for delivery. We have a Farm and Fleet I'll check after work.

I did, yes. I double-checked my measurements and in that picture the pad is a little too close to the house. I further filled in the front, added base and compacted it with a hand compactor. I now have a full 36 in clearance on all sides including the back. And my level says everything is good.
 
That little spot you have there 1-2 wheel barrel loads would fill that maybe even one. Just mix it right in the wheel barrel with a shovel 4 60-80 lb bags buy couple of sticks of 2x4 make a square form save little extra 2x4 use that to smooth it out don't need special tools. I have done it all with just 2x4's use it as a screed, float, and troweling the end goal is smooth it out push the gravel under the concrete. IT's not going to look perfect but not pouring a foundation. Probably have less then $40 invested in the concrete. Tons of video on Youtube how to pour a AC condenser pad.

I pour my own but it's not something that everyone is going to want to try.
Those Pads he has are fine so long as he does not get any extreme weather events. When I pour the pad I put in steel and I also hammer some 2ft lengths into the ground. The item is then bolted onto the Pad so that no reasonable amount of wind can knock it over.

I don't think there will be enough wind near the house unless get a tornado if that happens won't be a house left. According to the specs empty BossBox weight is 400 lbs. Put batteries in there another 300 lbs plus inverter about 1000 lbs. Now that I think about it might be a better idea to dig up the dirt and compact 6" inches of gravel. Depending on how soft the dirt is there I'm in Phoenix dirt here is almost concrete once over with the plate compactor were good.
 
300 lbs EACH, plus inverter. A FlexBOSS 21 and 3 batteries puts the weight at close to 1,700 lbs. I lost track of the number of times I said "<expletive> this stuff is HEAVY!" while putting this kit together.
Adds up real fast one reason I built a cart under my batteries with 2200 lb casters. It's lot of weight if it was me would pour a 6" thick pad over 12"inches of compacted gravel can go 4" thick just larger area twice as big as the cabinet.
