12 Volt Solar Systems
Dean talks customers through their system remotely after the job — after-sale support that shows up in review after review.
That's unusual enough to be decision-relevant: if you're travelling through Hervey Bay with a 12V fault, the realistic expectation based on reviews is a same-day diagnosis rather than a booking queue. For more complex builds — lithium upgrades, multi-MPPT solar systems, DC-DC charger installs on caravans or boats — multiple customers describe meticulous workmanship and genuine follow-up after the job, not just a bill at the end. Before committing to a big build, it's worth asking Dean directly about lead times, since a two-person operation this busy will have capacity limits that reviews alone won't tell you.

About 12 Volt Solar Systems
Dean and Yolanda run this Hervey Bay-based 12-volt specialist together, and reviews consistently map them to distinct strengths: Dean handles the hands-on electrical diagnostics and installation work — fixing faulty wiring, troubleshooting charging faults, fitting lithium battery systems and DC-DC chargers — while Yolanda is repeatedly called out for her pre-sales advice and after-care, including a case where her guidance saved a boatie thousands in wrongly-specified batteries. The business sits in a niche that general solar installers rarely serve well: 12-volt systems for campervans, caravans, motorhomes, and boats, including complex multi-component setups like the 800W solar, 930Ah lithium, three MPPTs, DC-DC charger and 3000W inverter build completed in a single day for one customer. Beyond installations, they diagnose and repair faults in systems installed elsewhere — several travellers stopped in mid-trip with charging or inverter problems and left the same day with everything sorted, sometimes with Dean talking owners through fixes remotely once they'd returned to their van. They stock a working range of 12V components in-store — panels, batteries (including lithium), controllers, inverters, satellite systems, and cable — so parts and labour often happen in one visit rather than requiring a return appointment. For travellers passing through Hervey Bay with a broken system, the pattern in reviews is clear: they accommodate short-notice and same-day visits, they don't charge for small troubleshooting wins, and they're patient explaining apps and system operation to people who aren't technically confident.
Best for: diagnosing and repairing faulty 12V systems installed elsewhere, complex lithium and multi-MPPT solar builds for caravans and boats, and travellers needing same-day electrical fixes while passing through Hervey Bay.

Does 12 Volt Solar Systems take walk-in or short-notice jobs?+
Based on multiple reviews, yes — this is one of the business's most consistent patterns. Travellers passing through Hervey Bay with charging faults, inverter problems, or wiring issues regularly report being fitted in on the day or at short notice. One customer had a campervan rewiring job completed while passing through from Melbourne, and another had solar issues in a new van resolved within an hour. That said, for larger planned builds, it's worth calling ahead to check Dean's schedule, since availability will vary.
What types of vehicles and setups does this business work on?+
Reviews cover a wide range: campervans, caravans, motorhomes, and boats are all mentioned specifically. Work includes everything from single battery replacements and small solar kits through to complex multi-component builds — one review details an 800W solar, 930Ah lithium battery bank, three MPPT controllers, a DC-DC charger, and a 3000W inverter all installed in a single day. They also do auto electrical work including reversing cameras, and supply components for DIY setups like Fraser Island camping kits.
What do customers say about pricing at 12 Volt Solar Systems?+
Pricing is one of the most frequently praised aspects across the reviews we read. Words like 'reasonable,' 'competitive,' and 'well priced' appear consistently, and several customers specifically note they were surprised by how low their bill was. In at least one case, a customer had a solar system reprogrammed at no charge after a Brisbane installer set it up incorrectly. Yolanda's pre-sales advice has also been credited with saving customers money by steering them away from incorrect equipment before purchase.
Who does the work — is it just Dean, or are there other staff?+
Dean does the hands-on installation and electrical diagnostics, and is consistently praised for knowing 12V systems inside out. Yolanda handles customer advice, sales, and after-care — she's specifically named for her pre-sales guidance and follow-up calls, and one review credits her with saving a boat owner thousands by correcting bad battery advice from an electrician. A team member named Jalanba is mentioned in one review, suggesting occasional additional staff, but Dean and Yolanda are the consistent presence customers encounter.
Can 12 Volt Solar Systems help if my existing solar or battery system isn't working properly?+
This is actually a core part of what they do, based on reviews. Several customers brought in systems installed by other businesses — in Brisbane, Melbourne, and elsewhere — that weren't working correctly, and had them diagnosed and repaired on the day. Faults covered in reviews include incorrect programming, charging system failures, wiring problems, and inverter issues. Dean has also talked customers through fixes remotely by phone when they'd returned to their vehicle after a visit. If you're having trouble with an existing system, this looks like a realistic option for a diagnosis visit.
