About Solar Kits — Pre-Configured Systems

Solar Kits — Pre-Configured Systems for Home, Cabin, and Off-Grid Solar panel kits take the guesswork out of going solar. Instead of matching panels, inverters, batteries, and racking part-by-part, a pre-configured solar kit bundles components that are already electrically matched — panel strings sized to the inverter's MPPT window, batteries matched to charge current, and racking rated for the modules. At Portlandia Electric Supply, we stock solar panel kits for every project size, from 3kW cabin systems to 18kW whole-home hybrid builds. Choose your kit type: Grid-tied kits deliver the lowest cost per watt for bill reduction. Hybrid solar kits add battery backup, keeping critical loads running through outages while still exporting to the grid — built around all-in-one hybrid inverters like the EG4 FlexBOSS18, EG4 18kPV, and Sol-Ark 5K. Off-grid solar kits pair an inverter/charger (EG4 12000XP, MidNite pre-wired systems) with LiFePO₄ battery banks for cabins, RVs, and remote sites with no utility connection at all. Size from your power bill: divide your average monthly kWh by 30, then by your local peak sun hours (4–5.5 across most of the US) — that gives your target array size in kW. A 900 kWh/month home typically needs a 7–8kW kit; cabins and RVs often run on 1–3kW with 5–10kWh of storage. Every kit ships with full manufacturer warranties — 25-year panel performance, up to 10-year inverter and battery coverage — and our team provides free kit design and compatibility checks before you buy.

Contact Portlandia Electric Supply — kit design is what we do all day. 5kW Starter Kit — Perfect for Grid-Tied Homes Our 5kW starter kit is the ideal entry point for homeowners looking to reduce their electric bill and gain energy independence. The kit includes ten 500W monocrystalline solar panels, a Solis 5kW grid-tie inverter with dual MPPTs, a WiFi monitoring dongle, aluminum rail mounting hardware with L-feet and clamps, DC and AC disconnects, and 50 feet of MC4 PV cable. This kit produces approximately 6,500-7,500 kWh per year, enough to offset the average US home's electricity by 40-60%. The plug-and-play design is compatible with net metering programs and is eligible for the 30% federal Investment Tax Credit (ITC). 10kW Battery Backup Kit — Whole-Home Protection For homeowners in areas with frequent grid outages or time-of-use pricing, our 10kW battery backup kit provides peace of mind and energy arbitrage. The kit includes twenty 500W bifacial solar panels, a Sol-Ark 12K hybrid inverter with integrated rapid shutdown and generator input, a SOK 48V 100Ah server rack battery (expandable to 400Ah), aluminum mounting hardware, disconnects, combiner boxes, and all necessary DC cabling. The 10kW array produces 13,000-15,000 kWh annually, while the 5-20 kWh battery bank provides 8-24 hours of whole-home backup during outages. The Sol-Ark inverter's time-of-use mode shifts solar energy to peak-rate periods, maximizing savings. Off-Grid Cabin Kit — True Independence in the Wilderness Our off-grid cabin kit is designed for remote locations where the grid is unavailable or prohibitively expensive to connect. The kit includes eight 500W panels, a Sol-Ark 8K hybrid inverter (or Sol-Ark 12K for larger loads), a 10kWh LiFePO4 battery bank, a backup generator auto-start interface, 30A MPPT charge controller, DC lighting and USB outlets, grounding equipment, and a complete wiring diagram. The system produces 3,500-4,500 kWh annually, sufficient for a small cabin with LED lighting, a refrigerator, a well pump, and occasional power tools. The generator auto-start ensures batteries stay charged during extended cloudy periods, and the EMP-hardened inverter protects against electromagnetic threats. All Components Included — No Hidden Costs Every Portlandia Electric Supply solar kit is complete. We do not sell partial kits that require you to source additional parts from unknown vendors. Each kit includes: solar panels, inverter, batteries (where applicable), mounting hardware, DC and AC wiring, disconnects, conduit, grounding components, monitoring equipment, and detailed installation instructions. Optional add-ons include battery expansion packs, EV charging stations, generator integration kits, and professional installation services. DIY-Friendly Design Our kits are designed with the DIY installer in mind. Components are pre-selected for compatibility, and our included wiring diagrams show every connection point clearly. Many of our customers complete their installation in a single weekend with basic electrical knowledge and common tools. For those who prefer professional installation, we maintain a network of certified installers across the Pacific Northwest and can coordinate installation for any kit purchase.
