RV and motorhome owners benefit hugely from a battery parking AC that ALSO runs from shore power at campgrounds. The architecture: shore power → smart inverter charger → 280 Ah LiFePO4 bank → parking AC. At a campground EHU, the AC runs effectively for free; off-grid, the same battery delivers 6–10 hours of cooling.

Shore-power voltages — 30A vs 50A North America, 16A/32A EU

North America RV: 30A 120V (3.6 kW) standard, 50A 240V (12 kW) for class-A motorhomes. EU campgrounds: 16A 230V (3.7 kW) standard, 32A 230V (7.4 kW) larger sites. Parking AC needs only 800–1,200W AC input — all standard pitches support it.

Smart inverter charger selection

Victron MultiPlus 12/3000/120 or 24/3000/70 covers North American 30A pitch. EU 16A pitch: MultiPlus 12/2000/80 or 24/1600/40. Auto-switches between shore and battery.

Transfer switch — AC and DC paths

When shore power is connected, the inverter passes through AC to onboard outlets AND charges the battery; the parking AC continues running on DC from the now-charging battery. Seamless transition.

Recommended models for RV / motorhome

Class-B and small Class-C: ZH 1000 12V ZH 1000. Class-A and large Class-C: VS02 PRO 24V VS02 PRO. All four VS02 PRO / ZH 1000 / VC 1000 / VC 2000 compatible with both 12V and 24V house systems.

Combined with rooftop solar for full off-grid capability

Add 400W rooftop solar + MPPT. Sustainable indefinitely in summer mid-latitude sun. Shore power becomes optional for warm-weather campers.

Frequently asked questions

Does the AC run off shore power directly?

No — the AC is DC. Shore power charges the battery via inverter charger; AC runs from battery.

Can I use a 15A pedestal in an emergency?

Yes — 15A 120V campsite supplies 1.8 kW which fully charges the battery and runs the parking AC continuously.

Will the inverter charger handle the AC inrush current?

Yes — modern LiFePO4 banks buffer the AC inrush; the inverter charger sees only the smooth bank-charging current.

Is this compatible with European 230V campgrounds?

Yes — choose the 230V inverter charger variant. EU pitch standard 16A 230V is more than sufficient.

Does Vethy supply EU-spec RV install kits?

Yes — 230V/16A and 32A pitch-compatible kits. Email sales@vethy.com or call +86-532-87729918 for combined heating + cooling kits, solar/shore-power packages and CIF pricing within 24 hours.

Can I install all this myself?

Most RV owners use a certified RV technician for the inverter charger and transfer switch wiring. AC rooftop install is straightforward DIY.
