Solar Kits — Pre-Configured Systems for Home & Business

Solar Kits — Pre-Configured Systems for Home & Business

Why Choose a Pre-Configured Solar Kit?

Solar kits eliminate the guesswork from system design. Instead of researching which inverter works with which panels, which charge controller matches your battery voltage, and how many panels you need to charge your battery bank, our kits provide complete, matched systems that are ready to install. Every component in our kits has been selected for quality, compatibility, and value — we've done the research so you don't have to.

Pre-configured kits are ideal for:

• Homeowners seeking battery backup or grid-tie systems
• Cabin and remote property owners needing off-grid power
• RV, van, and marine enthusiasts looking for mobile solar
• Small business owners reducing energy costs
• DIY installers who want professional results without custom engineering

5kW Starter Solar Kit — Grid-Tie for Homeowners

Our 5kW Starter Solar Kit is the perfect entry point for homeowners looking to reduce their electricity bills and gain energy independence. This grid-tie system includes 10x 550W high-efficiency monocrystalline panels, a premium string inverter, DC combiner box, AC disconnect, mounting hardware, and monitoring equipment. The 5kW system produces approximately 6,500-7,500 kWh annually, depending on location and sun exposure — enough to offset the average American home's electricity consumption by 40-60%.

The kit is designed for installation by qualified electricians or experienced DIYers with electrical competency. All components are UL listed and code-compliant, and the system includes a single-line wiring diagram, permitting documentation, and interconnection application templates. With the 30% federal tax credit, the net cost of this system is approximately $5,000-$6,000, delivering a payback period of 4-7 years depending on local electricity rates.

10kW Battery Backup Solar Kit

For homeowners who want both solar savings and energy resilience, our 10kW Battery Backup Solar Kit combines grid-tie solar with battery storage for seamless backup power during outages. This system includes 20x 550W panels, a hybrid inverter with battery integration, and a 10kWh lithium battery bank. During normal operation, the system feeds solar power to your home and the grid, reducing your electric bill. During grid outages, the battery automatically powers your essential circuits — lights, refrigerator, security systems, and outlets.

The battery backup kit provides 8-24 hours of backup power for essential loads, depending on consumption. Add additional batteries for extended runtime. The hybrid inverter supports AC coupling for existing solar systems, meaning you can add battery backup to an existing grid-tie installation without replacing your current inverter.

Off-Grid Cabin Solar Kit

Our Off-Grid Cabin Solar Kit is designed for remote properties, tiny homes, and off-grid cabins that have no utility connection. This complete system includes 6x 400W panels, a Sol-Ark 12K hybrid inverter, 4x EG4 lithium batteries (20.5kWh total), charge controller, mounting hardware, and all necessary electrical components. The system provides 2-3 days of energy autonomy for typical cabin loads and can be expanded with additional panels or batteries as needed.

The off-grid kit includes a detailed wiring diagram, installation manual, and system monitoring equipment. The Sol-Ark inverter supports generator backup for extended cloudy periods, ensuring you have power regardless of weather conditions. With proper installation and maintenance, this system provides decades of reliable, maintenance-free energy for your off-grid retreat.

All Components Included — No Hidden Costs

Every solar kit from Portlandia Electric Supply includes all necessary components for a complete installation:

• Solar panels with MC4 connectors and bypass diodes
• Inverter or charge controller (matched to system type)
• Batteries (for off-grid and backup systems)
• Racking and mounting hardware (roof or ground-mount options)
• DC disconnect and combiner box
• AC disconnect and breaker
• Monitoring system and app access
• Wiring diagram and installation manual
• Permitting documentation and interconnection templates

We don't sell "panel-only" kits that leave you scrambling for inverters, hardware, and electrical components. When you buy a solar kit from PES, you have everything needed for installation, with compatible components that work together seamlessly.

DIY-Friendly with Professional Results

Our solar kits are designed for competent DIY installation while delivering professional-grade results. Every kit includes step-by-step instructions, color-coded wiring diagrams, and component datasheets. Most homeowners with basic electrical knowledge and tool skills can complete the installation in 1-3 days, depending on system size and roof complexity.

We always recommend having a licensed electrician review your installation and make the final grid connection for safety and code compliance. Many of our customers complete the physical installation themselves and hire an electrician for 2-4 hours of final connection and inspection — saving thousands on labor costs while ensuring code compliance.
