Off-Grid Power Solutions for Motorhomes

In the world of motorhome touring, having the right equipment can make all the difference. Here are some key upgrades that can help ensure a smooth trip.

For those who frequently move around, a B2B charger is more important than a solar panel. Devices like the EcoFlow Alternator Charger, manufactured by EcoFlow, are crucial for motorhome infrastructure, particularly for campervans. A B2B charger can shove 40-80A into your leisure battery while you're on the move, automatically recharging it.

When it comes to batteries, the larger the capacity, the longer it will take to recharge from flat. For motorhomes, a larger battery bank and a beefy B2B charger are recommended. Upgrading to modern lithium batteries can be beneficial, as they are lighter and more energy dense, and offer a much greater depth of discharge. A 150Ah lithium battery is a good starting point for anything from a campervan upwards, while a larger battery, such as a 628Ah lithium battery, can allow you to camp off-grid for several weeks.

Solar panels are another essential upgrade, especially for motorhomes with limited space. A 150W solar panel is a starting point, and fold-up panels can be a good option for campsite use. When adding a solar panel, choose the largest capacity that can physically fit on the roof, subject to payload.

While solar power is a great source of renewable energy, its output can be vastly reduced in winter, often producing only 0.1A compared to 8A in summer. This is where a B2B charger comes in handy, as it can help top up your battery while driving between campsites.

Inverters convert 12V DC battery power into 230V AC power, but some energy is lost in the conversion and high-power devices consume enormous current. It's important to prioritize energy-efficient gadgets and devices when upgrading a motorhome's battery and charging systems. Appliances like induction hobs and super-efficient blown-air heaters are examples of energy-efficient motorhome appliances.

However, not all appliances are as energy-efficient. Microwaves and fan heaters are two of the heaviest loads that can be run off an inverter. A typical 800W microwave doesn't consume 800W, but rather its input power consumption is typically double that. Therefore, it's important to consider energy-efficient alternatives, such as the best air fryer for a motorhome, which will generally have a less demanding load.

Gas heating systems in motorhomes require electricity to ignite the flame and power the blown-air fan. Therefore, having a reliable power source is crucial. A power station unit, such as Ecoflow, Anker, Sherpa, or Jackery, provides a useful, safe way of adding a mains inverter without draining down the main battery bank.

When plugged into an electric hook-up on a campsite, the mains electricity triggers the motorhome's built-in charging system, which then recharges the leisure battery. However, it's important to make sure your built-in charging system is compatible with the battery type you're buying, as not all chargers will recharge a lithium unit.

Lastly, when setting off on tour, it's important to avoid common touring errors to ensure a smooth trip. This includes ensuring your power station and solar panel are properly installed and maintained, and that your appliances are energy-efficient to conserve power.

In conclusion, upgrading your motorhome with the right power solutions can greatly enhance your touring experience. Whether it's a B2B charger, a larger battery, or energy-efficient appliances, these upgrades can help you travel further, stay longer, and enjoy your trips more.
