Off-Grid Solar Cabin Kit — Complete Energy Independence

Complete Off-Grid Solar Cabin Kit — Energy Independence Made Simple

What's Included in the Off-Grid Solar Cabin Kit

Our Off-Grid Solar Cabin Kit is carefully designed to provide reliable, round-the-clock power for essential cabin loads including lighting, refrigeration, water pumps, small appliances, and device charging. The kit features 6x 400W high-efficiency monocrystalline solar panels, delivering a combined 2,400 watts of peak solar capacity. These premium panels capture maximum energy even in suboptimal conditions, ensuring your batteries stay charged through cloudy days and winter months.

At the heart of the system is the industry-leading Sol-Ark 12K hybrid inverter. The Sol-Ark 12K is widely regarded as the most capable off-grid inverter on the market, offering 12,000W of continuous output power with surge capacity for starting motors and pumps. It features dual AC inputs for generator backup, grid-tie capability if you ever want to connect to utility power, and advanced battery management that maximizes cycle life.

Energy storage is provided by 4x EG4 lithium iron phosphate (LiFePO4) batteries, delivering a total of 20.5kWh of usable storage capacity. LiFePO4 chemistry is the gold standard for off-grid applications because it offers exceptional cycle life (6,000+ cycles), thermal stability, and safety. Unlike lead-acid batteries that require regular maintenance and ventilation, these sealed lithium batteries are maintenance-free and can be installed indoors without off-gassing concerns.

2-3 Days of Energy Autonomy

With 20.5kWh of storage and efficient 400W panels, this system provides 2-3 days of energy autonomy under typical cabin loads. That means even during extended periods of cloudy weather, your essential systems keep running. Pair the system with a small backup generator connected to the Sol-Ark's generator input, and you have unlimited off-grid capability regardless of weather conditions.

Autonomy is calculated based on average cabin consumption of 6-10kWh per day — enough for LED lighting, a small efficient refrigerator, water pump, phone/laptop charging, and occasional power tool use. If your loads are lighter, autonomy extends even further. The Sol-Ark's built-in monitoring system lets you track consumption in real-time, so you always know your battery state of charge.

Incredible Value: $6,615 After Federal Tax Credit

The complete Off-Grid Solar Cabin Kit is priced at approximately $6,615 after the 30% federal solar tax credit (ITC). This represents exceptional value for a complete, pre-engineered off-grid power system. When you consider that grid extension to remote properties can cost $15,000-$50,000+ depending on distance from existing utility lines, solar plus storage is often the most economical choice for remote cabins.

At Portlandia Electric Supply, we leverage our wholesale purchasing power and direct relationships with manufacturers to offer pricing that retail competitors cannot match. We don't have the overhead of a fancy showroom or commissioned sales staff — we pass those savings directly to our customers. Plus, as a Pro Account holder, you may qualify for additional volume discounts and NET 30 payment terms.

DIY-Friendly Installation with Expert Support

Every Off-Grid Solar Cabin Kit comes with a detailed wiring diagram, installation manual, and component datasheets. The system is designed for competent DIY installation, though we always recommend consulting a licensed electrician for final connection and code compliance. Our technical support team is available to answer questions throughout your installation process — we don't just sell equipment, we ensure your project succeeds.

The modular design means you can start with this kit and expand later. Add more panels for increased production, additional EG4 batteries for extended autonomy, or AC coupling for even more flexibility. The Sol-Ark 12K supports up to 20kW of solar input and up to 80kWh of battery storage, so your system can grow with your needs.
