Energy Required for 150 Miles of Range

• 150 miles ÷ 2.5 mi/kWh = 60 kWh

Charging Time to Deliver 60 kWh​

Harvester Output	Time to Deliver 60 kWh	Range Added per Hour
6.0 kW	10.0 hours	15.0 miles/hour
7.2 kW	8.33 hours	18.0 miles/hour
9.6 kW	6.25 hours	24.0 miles/hour
11.5 kW	5.22 hours	28.75 miles/hour
17.6 kW	3.41 hours	44.0 miles/hour

Fuel Cost Estimate (Gas @ $3.15/gal, 0.8 gal/hr consumption)​

Output Power	Runtime	Fuel Used	Fuel Cost
6.0 kW	10.0 hr	8.0 gal	$25.20
9.6 kW	6.25 hr	5.0 gal	$15.75
11.5 kW	5.22 hr	4.2 gal	$13.23
17.6 kW	3.41 hr	2.7 gal	$8.51

Harvester Fuel Efficiency Metric (to deliver 60 kWh = 150 miles @ 2.5 mi/kWh)

Output (kW)	Time (hr)	Fuel Rate (gal/hr)	Fuel Used (gal)	Fuel Cost ($3.15/gal)	Cost per kWh	Cost per Mile
6.0	10.00	0.8	8.00	$25.20	$0.42	$0.168
9.6	6.25	1.0	6.25	$19.69	$0.33	$0.131
11.5	5.22	1.2	6.26	$19.73	$0.33	$0.132
17.6	3.41	1.5	5.11	$16.11	$0.27	$0.107

---

Conclusion:
Higher output = shorter runtime = less total fuel = lower cost per kWh and per mile.
The 17.6 kW Harvester delivers ~36% lower cost per mile than a 6.0 kW unit.

Full Battery Recharge: 150 kWh @ 17.6 kW Output


Time to Full Charge:
150 ÷ 17.6 = 8.52 hours


Fuel Use (1.5 gal/hr):
8.52 × 1.5 = 12.78 gallons


Fuel Cost ($3.15/gal):
12.78 × 3.15 = $40.27


Cost per Mile (350 mi range):
$40.27 ÷ 350 = $0.115/mile



Why the Harvester Should Be a Full-Capability Generator and Mobile Charger


1. Vehicle Charging to Full Capacity

• With battery sizes in the 130–150 kWh range, topping off requires 8.5 hours at 17.6 kW
• That’s only achievable if the system operates while stationary
• Enables complete overnight recovery in remote or infrastructure-limited locations

2. Mobile Generator Functionality for External Loads

• 17.6 kW = enough to support homes during outages (fridge, HVAC, lighting, EV, internet)
• Essential for emergency preparedness, natural disasters, and grid interruptions
• Also powers job site equipment, trailers, and field systems where grid access is unavailable

3. Bidirectional Energy Design Enables V2H and V2V

• Leverage the battery and Harvester together to support home backup (V2H)
• Power other EVs or recharge Scout from external energy sources (V2V and true off-grid)
• Maximizes energy utility, not just vehicle propulsion

4. Time and Energy Are Decoupled From Motion

• Energy recovery and generator operation shouldn’t be limited to drive cycles
• Harvester should function independently of vehicle drivetrain status

Solar Assist: Supplemental Charging & Load Reduction​

Assumptions:

• Solar panel output: 1.0 kW (e.g. Worksport Solis-style bed-mounted system)
• Sunlight availability: 4–6 hours/day of peak sun
• Vehicle efficiency: 2.5 mi/kWh

---

Daily Solar Contribution​

• Energy generated:
  1.0 kW × 4–6 hrs = 4–6 kWh/day
• Range added:
  4–6 kWh × 2.5 mi/kWh = 10–20 miles/day

---

Weekly Impact​

• Energy: 28–42 kWh/week
• Range: 70–105 miles/week
• Fuel offset (Harvester @ 1.5 gal/hr):
  • Time saved: 28–42 ÷ 17.6 = 1.6–2.4 hrs
  • Fuel saved: 1.6–2.4 × 1.5 = 2.4–3.6 gallons/week
  • Cost saved: 2.4–3.6 × $3.15 = $7.56–$11.34/week

---

Summary​

• Solar adds 10–20 miles/day passively
• Reduces Harvester runtime and fuel use by 15–20%
• Improves system efficiency, especially during idle or low-demand periods
• Enables silent, fuel-free energy recovery when parked

Scout has a unique opportunity to redefine what an electric vehicle can do by unlocking the full capability of its onboard generator. With 17.6 kW or greater output, the Harvester isn't just a tool for range extension, it’s a mobile energy platform capable of fully recharging the vehicle, powering external equipment, and supporting homes during outages. Enabling stationary operation allows this system to deliver energy where and when it’s needed most, operating efficiently under steady loads and independent of motion.


Once that core functionality is active, solar becomes a seamless complement. A 1 kW panel, such as a bed-mounted array, can contribute 10–20 miles of range per day, reducing fuel use and extending system flexibility. If Scout includes solar input connectors or a plug-in solar accessory that interfaces with the onboard charger, users could scale energy intake at camp or on worksites. This pairing turns the vehicle into a modular, resilient off-grid energy hub—more than just transportation.

Harvester specs are not known yet and I’m not sure if you’re trying to suggest that the Harvester generator will only be 17kW but that seems awfully weak. Most are speculating it will be in the 75-100 kw range.

I would hope it would at a minimum hit level 2+. Anything greater would be excellent

I think like the 6 other similar threads this is just speculation. There’s been minimal info offered to date but it’s all been implied. At this point everyone wanting to live off the grid using their Harvester is going to have to be patient until SM offers more. As for solar panels this has also been discussed extensively by EV owners who have years of experience and it isn’t as worthwhile as many think based on the cost and the amount of useable daily hours per day unless you live in the desert or treeless areas.
Everyone has run their numbers and used their logical math and science but until it is official, it’s all just repetitive heresay. But just one guys opinion who’s read so many of these threads and realizes that the biggest commonality is everyone wants more than SM can offer for an affordable starting price so I’ll stick with the BEV and hope that cost stays reasonable. Maybe in 18 months they’ll announce new magical batteries that offer 800 miles and weigh 20% less so I can go 6 weeks between “fill ups”

I don't think there are any threads with this data. The more people that speak up can make changes.

Kind sir, bringer of the fart horn, this is most certainly the People’s Democratic Republic of Scout that you find yourself in, but I would also suggest that you, uh, get a feel for the culture of this space. There are people here who love them some fresh, chewy data, but it’s probably better served up as something you work up to after you gain the trust of the regulars. We love people who use the search function. Love them. Kiss kiss.

Def need the megaphone. Tbh.. the only reason I am on this forum is bc I was told that was the only way to get the info across and that Scout was looking for feedback. take care.

Please don’t leave? This was meant in good fun. I truly didn’t mean to be a jerk. Please accept my apology. It is not my intention to drive people away, but I am a horrible communicator. Truly.

Please stay and keep talking to people. Your ideas deserve to be heard and the people at Scout are really nice and they do read this forum.

Oh no, I didn't take it that way, but you def need the megaphone on these with custom lock sounds and horn noises. I wish you could still do custom driving noises bc it would be a fart the whole way.

Ah. Well, I respectfully disagree with regards to the need for a megaphone and custom sounds. Unfortunately, it appears that we are at an impasse and I will not be subscribing to your newsletter. A good day to you.
