Caravan Solar Installation & Lithium Batteries in Port Stephens

A typical caravan solar install starts around $950 for a single 200W panel, MPPT regulator, cabling and fitting, and moves upward from there as you add panels, a DC-DC charger, a battery monitor and heavier cabling. A full off-grid package with lithium batteries, 400W or more of solar and a proper 12V distribution board generally lands between $3,000 and $6,000 depending on the battery capacity and inverter size you choose. We measure your roof, work out your realistic daily power use and quote in writing before anything is fitted. Call 0432 089 987 for a free assessment in Port Stephens or Newcastle.

Most travellers who free camp comfortably run between 300W and 600W of solar. A 12V compressor fridge alone typically draws 30 to 60 amp hours a day, and lights, water pump, phone charging, fans and a diesel heater add on top of that. We size the array to cover your worst realistic day rather than a perfect sunny one, because a system that only works in midsummer is the most common mistake we are asked to fix. If you run an air conditioner or induction cooktop you will need a larger array, a bigger battery bank and an inverter matched to the load.

For most regular travellers, yes. A 100Ah lithium battery gives you close to 100 usable amp hours, while a 100Ah AGM realistically gives you about 50 before you start damaging it, so you get roughly double the usable power for a third of the weight. Lithium also charges much faster, which matters when you only get a few good hours of sun. The catch is that your charger, DC-DC unit and solar regulator must all have a lithium profile, and the battery needs to sit somewhere it will not freeze or overheat. We check the whole charging chain before recommending an upgrade so you do not end up with an expensive battery that never fully charges.

A DC-DC charger sits between your vehicle alternator and your caravan batteries and boosts the incoming voltage so the batteries actually reach a full charge while you drive. Modern vehicles with smart alternators drop their output voltage once the starter battery is topped up, which means a plain Anderson plug connection often leaves your house batteries sitting half charged. Most DC-DC units also include a built-in solar regulator, so one box handles both driving and solar charging. If you have a vehicle built in the last decade and you rely on driving to recharge, a DC-DC charger is one of the highest value upgrades you can make.

Yes, electrical fault diagnosis is one of our most requested jobs. Common causes are a failed solar regulator, corroded or undersized cabling, a blown inline fuse at the battery, a faulty Anderson plug connection, a battery past its useful life or a charger set to the wrong battery profile. We test the system under load rather than guessing, check voltage drop across every leg of the circuit and show you the readings so you understand what failed and why. Most diagnostic jobs are completed the same day at our Taylors Beach workshop.

Yes. We supply and fit pure sine wave inverters sized to what you actually intend to run, from a compact 600W unit for laptops, chargers and a coffee machine through to 2000W and larger for kettles, microwaves and induction cooktops. Larger inverters need heavy cabling, correctly rated fusing and a battery bank capable of the current draw, so the inverter is only one part of the job. Where 240V outlets are involved the work is completed to Australian wiring standards with the correct changeover protection.

Yes. We install and upgrade 12V and solar systems on caravans, pop-tops, camper trailers, motorhomes, RVs and slide-on campers. Low-profile roofs and pop-top designs need panel and cable routing planned carefully so the roof still seals and lifts correctly, which is where a rushed install usually causes leaks. Send us a photo of your roof and switchboard and we can usually scope the job before you arrive.

For fault finding, battery replacement, regulator swaps and smaller upgrades we can come to you across Port Stephens, Newcastle, Lake Macquarie, Maitland and the Hunter Valley. Full solar installs, lithium conversions and inverter fit-outs are better completed at our Taylors Beach workshop where we can seal roof penetrations properly and load test the finished system. Call 0432 089 987 and we will tell you which suits your job.
