Product Information

For example, a battery with a capacity of 100 Ah can theoretically deliver a current of 1 ampere for 100 hours or 10 amperes for 10 hours before it is completely discharged. The actual runtime of the battery will depend on various factors, such as the load applied, temperature, and age of the battery. In this guide we focus on small inverters as these are the most useful to those camping in tents, caravans and motorhomes. Typically these are in the range 100 watts (W) ideal for low powered items like phone chargers and laptops to 3,000W for a kettle of heater although this high output would drain the typical battery set-up in minutes. How inverters work Another great reason to install a solar power system aboard your campervan is the positive environmental benefits. As you are not connecting to a nations national electrical grid that typically uses fossil fuel, you are essentially not creating any harmful pollutants. Advantages of a solar power system The TEC3M relay is designed to turn on at any voltage over 13.5V and off at anything lower, thereby preventing any undue drain on the vehicle battery when not being charged.

For UK-wired vehicles, this can cause a safety issue. Power is travelling down the neutral wire rather than the live wire. This means that an appliance will work, but live power will continue to flow to it even when it is switched off. Each power bollard (or EHU post) usually has one to four power connection points, although sometimes up to eight. One connection for each pitch. You should only install a mains power electrical supply system aboard your campervan if you intend on operating high-voltage appliances.Low-wattage appliances designed specifically for camping are readily available from outdoors suppliers. If you want to run a hairdryer, you will need an inverter of at least 1,500W, but taking that amount of power from a standard leisure battery will flatten it in just a few minutes. The following table can be used as a guide when using single-core Polyvinyl Chloride (PVC) insulated cables. Cable Sizing for Inverters The mains supply from the utility companies should be a pure sine wave with the voltage rising and falling in a steady rhythmic pattern. This is what most appliances are designed to use to work efficiently.

A powerful alternator coupled with a lithium battery can power microwave ovens, vacuum cleaners, hairdryers and so on, while the battery itself has a fast recharge rate. While such set ups are, and are likely to remain, expensive, they do point the way forward for mobile power in motorhomes. Our total wattage worked out at under 200W, however we chose to install a 500VA inverter as the price difference between the 250VA and the 500VA inverter is negligible. This future proofs our system and means that if we want to use slightly higher wattage appliances in the future, this will be possible. Also, in reference to my comments above, I’m only referencing pure sine wave inverters and no modified sine wave inverters. As soon as possible in the positive wire from the battery, fit a fuse. 10/15 amps is OK for all the scope kit & heaters you can imaging hanging on. But it will blow promptly if you get a short circuit somewhere. Big batteries will provide enough current to set wires glowing red.Inverters may be rated according to their peak power or to their average power. The first is the maximum power that can be provided for an instant. Any longer would result in damage or automatic shutdown. The second is the power that can be provided on a constant basis, without time limits. Peak power is normally around twice average power so it does pay to read the label carefully. Peak power is useful to know when sizing an inverter for loads with a high starting current (see below). Your vehicle has a native 12-volt system already in place. As your campervan has a native 12-volt system onboard, creating an additional 12-volt campervan electrical system to power all 12-volt appliances is a relatively simple process.
