The RV Power System Planner
Size the battery bank, solar array, inverter and wiring to your own rig's real daily energy use instead of a guess, wire it to hold ABYC and NEC practice instead of whatever gauge was in the garage, and know your state of charge, solar harvest and generator settings before every trip off grid: an at-a-glance system card, a daily energy budget worksheet, a battery bank sizing sheet, a solar sizing sheet, an inverter and generator sizing sheet, a wiring, fusing and disconnect plan, a buying decision sheet by use and budget, a boondocking and dry camping plan with a water budget and a payback tracker, a seasonal storage and battery maintenance checklist, a reusable monitoring log and a budget planner.
- 11 fill-in worksheets, 33 print pages
- 2 filled-in examples to copy the format from
- Companion Excel / Google Sheets tracker with the battery, solar and wire gauge formulas built in
- Online buyer guide with budget ranges and Amazon links, by ladder and budget tier
Replaces the guessed wire gauge, the converter left on the wrong charge profile after a lithium swap, the solar array sized off a rule of thumb, and the pre-trip check done from memory.
30-day money-back guarantee. Use it all; if it doesn't help, every dollar back.

- 1 companion spreadsheet. An editable workbook: a battery bank and solar array calculator using this site's own depth-of-discharge and derate formulas, a wire gauge and fuse sizing calculator using this site's own voltage-drop and overcurrent math, a one-time power system budget with a running total, and a reusable monitoring log. Tabs: Battery & solar calculator, Wire gauge & fuse calculator, Budget, Monitoring log.
- 1 start-here page. The four sheets to fill in the first 20 minutes, and which sheet to reach for when.
Plus the online buyer guide
Both this site's campground and boondocking build ladders at three budget tiers each, every item with a budget band and a link, plus every product the kit names, kept current on this site. Your kit links straight to it, and each link opens Amazon's current price, not the one from the day the PDF was printed.
Who it's for
- Anyone planning a first lithium conversion who wants the converter, solar controller and DC-DC charger profile question settled before it becomes an expensive mistake
- Anyone sizing solar for the first time who wants their own daily load and region's sun hours run through the arithmetic instead of a rule of thumb
- Anyone who has never run the ABYC voltage drop and NEC overcurrent math and wants the exact steps with a real example
- Anyone deciding between the campground and boondocking build ladders who wants a real decision process by how they actually camp
- Anyone who boondocks regularly and wants a reusable monitoring log, a water budget and a payback tracker for campground fees and generator fuel avoided
Who made this
Built by the RVPowerCalc team from the same battery bank, solar array, wire gauge and inverter sizing formulas the free site's calculators run on, laid out as a workbook to fill in with your own rig's real numbers rather than a page to read.

Questions
Does this tell me if my rig's wiring can safely carry a specific load?
No, and it never will. This kit is the same arithmetic as the free site's calculators, run on YOUR own current, run length and system voltage. Nothing here overrides your own rig's wiring, your converter's manual, or a qualified RV electrician's judgment on your specific installation.
Does this replace the free site?
No. The free site has the calculators, buying guides and reference charts; the kit is where your own rig's numbers get written down, dated and reused, plus the budget tracker, the payback tracker and the reusable logs the free pages do not carry.
I am switching to lithium for the first time. Is this useful before I buy anything?
That is exactly what the Battery Bank Sizing Sheet and the at-a-glance card are for: they walk through nameplate versus usable capacity, the lead-acid to lithium comparison, and the charger profile question, before you spend money on the wrong converter.
Does it cover both plugging in at campgrounds and boondocking off grid?
Yes. The RV Power Buying Decision Sheet and the online buyer guide both carry this site's two build ladders, campground and boondocking, because they genuinely serve different buyers and one list would give bad advice to one of them.
Printable or fillable on screen?
Both. Print it and write by hand, or open a worksheet PDF in a reader that supports typing and fill it on a tablet or phone.
What if it does not help?
Use the whole kit for 30 days. If it does not help, the refund form on the contact page gets every dollar back, no questions asked. Refund form.
