The importance of a solid electrical range when travelling in a motorhome

When travelling in a van or motorhome, the’electric autonomy Everything depends on it: preserving food, working on a computer, lighting in the evening, heating water, recharging appliances... A well-designed system prevents energy shortages, extends the life of equipment and makes your journey more stress-free.

What do we mean by “electric range”?

Travelling through France, Spain or Portugal in a van or motorhome is a real taste of freedom - but this freedom is based on one crucial point: the right equipment.’electric autonomy.

From the Basque coast to the roads of Andalusia, via the passes of the Pyrenees, having a reliable installation means never being dependent on a 230 V socket, even for several days at a time.

In France: comfort and standards

France is a road-trip paradise. Service areas, municipal car parks, electricity points... But access to a plug isn't guaranteed everywhere - especially in the mountains, on the Atlantic coast, or in protected natural areas. A good electric range allows you to : park freely (without plugging in), stay 100 % autonomous for several days, comply with VASP approval rules, which require a safe, compliant electrical installation.

Tip variable temperatures and Basque humidity reduce solar yield by 10 to 20 % → provide a solar margin and a reliable BMS on the lithium batteries.

In Spain: sunshine and maximum autonomy

Spain is the ideal playground for solar self-sufficiency, with over 300 days of sunshine a year in many regions (Andalusia, Murcia, Catalonia). Here, solar power becomes your main source of energy. A few tips: Lay your solar panels flat in summer (to limit heating), slightly tilted in winter. Spanish campsites often offer connections up to 10 A - so limit your consumption (12 V fridge, no 230 V air conditioning). Rural areas (Asturias, Galicia) require a good LiFePO4 lithium battery to last several days without recharging.

Information on Spain When driving for long periods between stages, install a DC-DC booster to recharge the alternator at full speed - very useful on long motorways (Madrid ↔ Seville ↔ Tarifa).

Portugal VS Northern Europe?

Portugal & Southern Europe - Heat changes the game

Below 35°C, a 12 V fridge consumes more power. AGMs don't like high temperatures; LiFePO4s cope better, provided they are well managed (BMS, air circulation). I'm predicting a margin of +30 % on solar for the Portuguese summers.

Northern Europe - Diversifying sources

In Brittany, Germany and Scandinavia, the amount of sunshine is decreasing: I mix solar + DC-DC, and I keep the 230 V charger for camping stops. The aim isn't to pile up the watts, it's to recharge regularly.

Mistakes I make and how we correct them at Campervan service in Anglet

Panels undersized for a compression fridge → aim for ≥ 300 Wp in France, further south.
Coupler-separator on a Euro 6/6d vehicle → install a DC-DC booster (20-40 A depending on the case).
No fuse as close as possible to the battery/panels/chargers → correct immediately.
Cables too thin → voltage drop, heat, perf at half-mast.
Big converter not useful → high standby; stick to 12 V as much as possible and keep a pure sine sized to the real need.

Weekends / mainland France AGM 100 Ah, 175-200 Wp + MPPT, 230 V 20 A charger, 12 V/USB sockets, LED. Simple, reliable, economical.

Roaming France ↔ Spain (12 V fridge) LiFePO4 150-200 Ah + BMS, 300-400 Wp + MPPT 30-40 A, DC-DC 30-40 A, battery monitor (with shunt). This is my “comfort” setup: we live normally, we're not looking for a plug.

Teleworking & long-distance commuting in southern Europe 2× LiFePO4 200 Ah (parallel), 400-600 Wp + MPPT 50-60 A, DC-DC 50-60 A, inverter-charger 2000 W if 230 V tools required. You really become independent.

Campervan Service installs and replaces your lithium battery (LiFePO4), sizes your loads (MPPT, DC-DC booster) and installs rigid or flexible solar panels on motorhomes / campervans, vans and converted vans. Clean, compliant work (fuses, cross-sections, VASP). Quick quote Basque Country
