The Smart Method for Mobile Energy review
Plan your RV solar and battery setup before you buy, so you only buy the parts once.

Is it worth it?
You've got the rig, or you're about to, and you want to park somewhere with no hookups for a few nights without the fridge dying. So you start reading. And every forum thread contradicts the last one. One guy swears 400 watts is the minimum, another runs fine on 200. Lithium is either essential or a waste. Meanwhile the parts add up to a couple of grand and you still don't know if they'll work together. That's the knot this guide tries to untie, and it goes at it in a sensible order: work out what you actually use in a day first, then size the battery to that, then the panels, then the inverter. The energy audit worksheet is the real centre of it. Once you know your daily watt hours, most of the other decisions stop being arguments and start being arithmetic. The page leans hard on a $2,800 versus $1,100 comparison between two imaginary owners. Treat that as the seller's illustration, not a number you'll hit. Your costs depend on your rig and your habits. What you're buying is a few hours of reading and an afternoon with a calculator, which is cheap next to buying the wrong battery once. It won't install anything for you, and nothing in it replaces a qualified check on DC wiring if you're not confident with fuses and gauge.
Pros
- Puts the energy audit first, before any shopping
- Worksheets turn vague sizing questions into numbers
- One payment, no subscription, instant download
- Covers wiring, fuses and safety, not just gear lists
Cons
- The page never says how long the PDF is or what the worksheets are (spreadsheet, fillable PDF, print and write)
- The 4,000+ owners figure and the two cost totals are the seller's claims with nothing behind them
- Gear and price advice dated to 2026 will drift, and there's no mention of updates or any support if you get stuck
What you get
A PDF guide of 13 chapters covering how RV power works, energy audits, battery chemistry (AGM, lithium, LiFePO4), panel selection, inverter and charge controller sizing, wiring and fuses, shore power, boondocking, monitoring, installation and full time setups. Plus five fill in worksheets: energy audit, battery sizing, solar output by season, an inverter checklist, and a final shopping list with a simplified wiring diagram.
Before you buy
- Refunds run 30 days through ClickBank, so keep the receipt email and note the date
- It's a digital download only, no printed book posted to you
- Spend ten minutes listing your appliances and their watt draw first, or the audit worksheet won't do much
Who it suits
Someone planning an RV solar or battery setup who hasn't ordered parts yet and wants a sanity check on sizing. Skip it if your system is already installed and working, or if you're comfortable enough with DC electrics to size a bank yourself.
