Hello Everyone!
Steve here with Million Acre Farms in Punta Gorda Florida, and I wanted to show the initial mockup of my Outdoor Leaf Cell Power Station.
This build is an Outdoorpower stationfor operating the small construction office we will be using whilebuilding our farm.
As it will Take Florida Power and Light 2+ months to get our power to us. This moves our calendar up, and when done, we can use it as a big UPS to keep our Irrigation pumps running when the power goes out.
The unit is housed in an Aluminum Outdoor Traffic Control Cabinet. Weatherproof, Super Tough, Secure, and Built to Last. (Bought it used off of Craigslist.)
Which I will be Internally and Externally Insulating to a Factor of R40-45 Almost a foot thick. (Rock, Earth, and Sand in the Blocks, with Foam insulation in the Cabinet)
Being in Florida, heat is certainly an issue.
So I have decided to use a small Concrete slab, Vented with a large pipe from underneath, a Solar Shade Pavilion,and a Cinder Block Enclosure filled with sand to help insulate the unit.
With the 2 Panels above shading the Enclosure, Ill be using one to power the 3000CFM DC Fans that will help cool the unit, and the other will run mysmall DC Water pump for my hand washing sink, and toilet facilities in the office.
The vent pipe coming in from bottomofthe enclosure, will be 6" PVC and will have 2 purposes. For runningwire to and from the Enclosure and office, as well as to Bring in Cool air from underneath the Office. It will be poured into the Slab, and the Control Cabinet will be Bolted to Studs that will be poured into the slab when it is constructed.
The pipe will be buried 3 feet down to help do a bit of geo-cooling to the unit as well.
If all else fails, I will use one of these little guys to assist in the hottest months...

or a telecom AC unit...

Both are 300-450$ and draw about 350-500 watts.
Either should be able to cool the small space quickly, only needing to run for a few minutes at a time. IF its needed at all.
The design of the enclosure and its surrounding structure, should help keep me at 80F or below, even when its approaching 100 outside. But until I have built it and tested it, that remains to be seen.
All of this was done to keep this battery and the electrical danger associated with it, away from my employees, and OUT of my office.
As this is my first Powerwall type battery, I wanted MAXIMUM Safety for my Employees and Myself.
Also, there will be times when we aremeeting partners and customers in the office, as well as using the latter half for the storage of expensive tools and farming equipment that we don't want damaged.
-----------------------------------------------------
The Build So Far:
- 28 Nissan Leaf, 7.2v 64ah LiPoly Cells, Configured into a 7s4p Pack. (Each Leaf Cells internal configuration actually makes this a 14s8p, but thats for another forum post. LoL)
- x8 -300Watt 37v 4'x8' Panels (Higher Quality, Don't have the Specs Handy, Will Edit Post Later)
- 60 Amp Offbrand Chinese MPPT Charge Controller, 3000 Watts Max at 48v(Well reviewed, and I intend to rework the internals and make sure its solid)
- AIMS Power 6000 Watt / 18000 Watt Peak Pure Sine Inverter Charger, with Split Phase 120/240
- Midnight Solar Combiner Box with x6 DC Breakers at 30 Amps Each
- x2 Sealed Lead Acid Batteries to run the pumps and fans, and a Cheapo PWM 12v Charge controller for those...
- 100 Amp 150V Main Breaker/Disconnect Switch for the Pack (Heavy DutyMarine Type)
- Grounding Rod
- 3300CFM 12vdcair cooling
- Copper Bus Bar
- T8 LED Fixture for cabinet lighting
- 12v Digital Thermostat and Relay for Fan Control
- Batrium Leafmon BMS to balance and manage the pack
And likely some other things I can't think of right now.
I will be using 2 Panels in parallel to get a Max charge voltage of 74vdc, into my MPPT controller, and using 4 banks of 600 Watts to get a max in wattage of 2400 watts charge.
Hopefully, I have done all my homework correctly, and I am not making a total arse out of myself with this setup, and with the configuration I intend to use.
If there are ANY Glaring issues, or errors that you guys can see, please do point them out.
I would rather fix it now, and do it right the first time.

So....
Tell me what you think!
Try not to be too rough on me, remember, first Powerwall build ever!
