FREE RV POWER CHECK

Will your RV power setup make it through the whole trip?

Tell us your nights, must-run loads and recharge options. In about 2 minutes, get the minimum usable capacity, your daily recharge gap and a startup-power check. Estimates and “I don’t know” are accepted. No email. No brand ranking.

Answer first, before any question

May fit under conditions

What has to run while you are off the grid?

This is the answer most likely to change the verdict.

The mission can be carried, but the day does not yet close on its own.

Low / insufficient confidence — no unit is recommended at this level of evidence.

What this answer assumes (5)
  • A two-night weekend
  • Essential loads only
  • No air conditioning
  • No recharge credited
  • An existing house battery system is not credited
  1. Step 1What trip are you trying to close?
  2. Step 2What must still work after sunset?
  3. Step 3What does the RV already have?
  4. Step 4What could change the architecture?

What trip are you trying to close?

Shore power changes the architecture before battery size does.

Loads a two-night, no-shore-power trip with a fridge and lights already filled in, then drops you straight into the load review. Every figure stays editable and nothing is submitted until you ask for the verdict.

1–7 nights.

Context only. The calculation uses the loads you declare in the next step.

Only the trip shape and the load choice are needed to start. Technical facts you do not know are accepted as Unknown: the verdict then names the next fact to measure, or abstains. It never guesses one for you.

Products this check may confirm — or rule out

Illustrative candidates, not a ranking. Your inputs determine the result. Affiliate status never determines technical eligibility.

Also checked by the catalog: Anker SOLIX C2000 Gen 2 — official page only, non-affiliate.

No product images here — the check decides, not photographs. It can also conclude that none of these units closes your setup.

What you get back

  • 01Minimum usable capacityThe watt-hours you actually need after inverter losses and a retained reserve — not a nameplate number.
  • 02Daily recharge gapWhether the solar or alternator you declare closes each day, or leaves the loop open.
  • 03Startup-power checkWhether air conditioning or another surge load can actually start — or stays unproven.
  • 04Simplest architectureThe plainest setup that works, or the one fact to measure before anything can be recommended.
An RV at camp without shore power, its overnight loads, its stored energy and its recharge pathsA travel trailer is parked off-grid. Fridge, lights, CPAP and air conditioning draw from a house battery through an inverter overnight. Solar on the roof and the vehicle alternator feed energy back during the day.

  • 01Mission energyDoes the whole trip close?Nights × declared Wh per night, minus credited recharge, against usable energy after inverter losses and a retained reserve.
  • 02Daily loopDoes each day pay for the night before?Credited recharge per day against the declared daily need. A trip can finish on stored energy while the loop stays open — those are different verdicts.
  • 03Peak and startupDoes anything trip at the moment it starts?Declared running watts plus the worst declared startup surge. Never inferred from average energy: undeclared means unproven, and unproven means no product is named.
