Camper van electrical systems and caravan electrical systems

From batteries to solar systems to fuel cells. You won’t get far nowadays without the right electrical system in your caravan or camper van. That’s why Intercaravaning.shop has a large selection from different electrical systems suppliers, so that you always find exactly what suits your needs and never have to stand in the dark.

Batteries for powering caravans and camper vans

AGM batteries

Regular acid-based battery, gel battery, AGM battery or lithium battery? The on-board battery is the core of a working camper van electrical system. As such, it’s more than recommended to carry out a quality check to compare the battery to your energy requirements. MT AGM Batteries from Büttner, Varta Professional Dual Purpose and Banner Running Bull AGM batteries are the favourites of most camper van owners from the AGM battery range at intercaravaning.shop. Like conventional 12-volt batteries, they use sulphuric acid as an electrolyte, but the liquid is bound in micro-glass fibre mats. The highly condensed electrode plates of AGM batteries also contribute to their extraordinary storage capacity, and charging cycles have less influence on the total charge capacity. In addition, AGM batteries hardly ever discharge. Thanks to their exceptional performance, AGM batteries from Banner and, in particular, Büttner’s MT AGM 120 batteries can be used as both on-board and starter batteries. Good to know: Banner Running Bull AGM batteries have 70 – 92 Ah. The Varta Professional Dual Purpose, at up to 95 Ah, is more for moderate energy requirements. MT AGM batteries range from 85 to 120 Ah, making the MT AGM 120 the camper van battery with the highest nominal capacity.

Liquid acid and gel batteries

Conventional 12-volt batteries with liquid sulphuric acid are considerably cheaper. However, they should never be discharged by more than half. This leads to the formation of sulphate crystals, which decreases output and charge capacity. In gel batteries such as the Exide Equipment Gel ES 900, the electrolyte acid is bound in gel and the power stores have thicker plates. That makes them heavier, but they can supply more power for longer – though they also need to charge for longer. Gel batteries are not suitable for concentrated quantities of electricity, which are required by larger inverters for the supply of 220 V, and lower temperatures also affect their performance. Compared to the otherwise seemingly superior AGM batteries, high-quality gel batteries such as those produced by Exide have a decidedly longer lifespan with over 1600 cycles at a max. discharge of 50% and are available with rated outputs up to 235Ah. The MT Gel 235 gen battery from Büttner even delivers 235 Ah.

Lithium batteries

On-board batteries based on lithium iron phosphate (LiFePo4) represent a completely different and very modern storage technology. The specialist Super B, for instance, specialises in the production of lithium batteries and advertises up to 100 kg less weight depending on the battery being compared and the size of the camper van, as well as a lifespan that is three times longer. With its Super-B 90 Epsilon, the Dutch company offers a lithium battery that does not respond to spontaneous increases in load with sudden voltage drops and doesn’t mind deep discharges. Even extreme temperatures have no effect on this lithium iron phosphate battery, which lasts up to 5,000 cycles. From Super B there are lithium batteries with charging currents from 90 Ah to 160 Ah. Only one model of Büttner Elektronik’s similar lithium LiFePO4 on-board batteries is stronger: the MT Li 180.

Sine wave inverters

Inverters such as the Sinus MT 1700 SI and Sinus MT 1700 SI-N c‍onvert the battery voltage (12V DC) into a purely sinusoidal 230V AC voltage for the operation of all on-grid devices. Compared to the MT 1200 series, the Sinus MT 1700 SI inverter is unfazed even when powering a coffee maker, vacuum cleaner or hair dryer. Thanks to smart functions such as automatic downshifting to stand-by mode or complete shutdown, Büttner’s MT series sine wave inverters are also relatively efficient in terms of power consumption. The Sinus MT 1700 SI-N inverter switches off automatically when the camper van or caravan is connected to mains power.

Power supply via fuel cell

EFOY fuel cell

The EFOY fuel cells available at Intercaravaning.shop are energy suppliers that are used as an alternative to complete solar systems. They transform chemical energy from methanol fuel cartridges made by the same companies into electrical energy, which is fed into the on-board battery. As with solar systems, the energy input of EFOY Comfort fuel cells to the 12 volt on-board battery is monitored by a charge controller. The fuel cell for the camper van starts automatically and stops charging when the battery is full. The manufacturer of the EFOY fuel cell advertises that this prevents harmful deep discharge of the on-board battery, thus extending its lifespan.

Petrol power generator

To use petrol to supply power, you need a classic power generator with an integrated tank like the Honda EU 10i. Nowadays, inverters of this kind are relatively quiet and lightweight. With 2.1 l in the tank, the Honda EU 10i runs for about 8 hours and delivers an output of 1000 watts. The largest Honda EU 30i has a strength of 3000 watts. Dometic also produces powerful, fuel-efficient petrol inverters with its TEC 29 B, TEC 30 EV and TEC 40 D. The strongest among them outputs a whopping 3500 W.
