Portable Sun LLC is a Michigan-based DIY solar equipment supplier carrying solar panels, inverters, lithium battery systems, EV chargers and mounting hardware from brands including Growatt, MidNite Solar, Canadian Solar, SunGold and CW Energy. Free sitewide shipping on most items. NABCEP-certified technicians provide free system planning proposals. Trusted by thousands of DIY solar builders across the United States.
Portable Sun LLC (portable-sun.com) is a Grand Rapids, Michigan-based solar equipment company founded and operated by Matthew C. Schoppen with a mission that has remained consistent since launch: make clean, reliable solar energy simple, affordable, and genuinely accessible for homeowners, RV owners, off-grid builders, and DIY solar enthusiasts across the United States. In a market crowded with anonymous online resellers and drop-shippers, Portable Sun has carved out a distinct reputation on the major DIY solar forums — particularly the DIY Solar Power Forum — for competitive pricing, knowledgeable phone support, and reliable LTL freight delivery that consistently arrives on time and undamaged. The company carries a comprehensive catalog of solar equipment across every major system component. Whether you're planning a 3kW rooftop system for a weekend cabin or a 30kWh whole-home battery backup, Portable Sun stocks the hardware you need from brands that have earned their place at the top of the DIY solar community's preferred supplier lists. Solar Panels At the heart of any solar system is the panel, and Portable Sun carries panels from two of the most respected manufacturers in the tier-one panel category. The Canadian Solar CS6W-545MB-AG Bifacial Panel is a 545W bifacial N-type module delivering high-efficiency output from both front and rear surfaces, compatible with ground mount and rooftop installations. For larger system builds, the CW Energy 595W Bifacial Solar Panel Pallet offers even higher per-panel wattage with FEOC compliance status increasingly required for federal IRA solar tax credit qualification — a critical consideration for any system installation in 2026 and beyond. Inverters Portable Sun carries grid-tie, hybrid, and EV charging inverter products covering the most common residential and light commercial system configurations. The Growatt 11.4kW Grid-Tie Inverter MIN11400TL-XH-US is a dual-MPPT string inverter for grid-tied systems requiring high-power output with wide voltage range input compatibility. For homeowners who want battery backup alongside solar generation, the Canadian Solar EP Cube Hybrid Inverter combines inverter, EPS emergency power supply, and battery management in a single all-in-one unit. Rounding out the inverter lineup, the Growatt 12kW Thor 50A Smart AC EV Charger is a Level 2 smart charger compatible with all major EV brands, making it the logical charging complement to a solar installation. Lithium Battery Systems The battery storage lineup is where Portable Sun's catalog shines most clearly for serious solar builders. The MidNite Solar MNPowerFlo5 30.72kWh Lithium Battery Kit is a six-battery server rack system delivering 30.72kWh of usable LiFePO4 capacity — enough for meaningful whole-home backup or full off-grid operation for a typical household. The SunGold 48V 100Ah Server Rack LiFePO4 Battery SG48100P carries UL1973 and UL9540A certifications — the dual safety listings increasingly required by local authorities for residential battery storage permits. For multi-battery arrays, the MidNite Solar MNBIGBUSBAR 280A Battery Busbar provides a high-current interconnection point with five main studs and six auxiliary slots. Mounting Hardware The IntegraRack IR-30 Solar Panel Ground Mount is an aircraft-grade aluminum ground mount system with a fixed 30-degree tilt angle — the optimal angle for most US residential latitudes and the most cost-effective mounting solution for ground-installed systems. Protection Devices The MidNite Solar MNSPD-600 Lightning and Surge Arrestor is a 600V DC surge protection device protecting inverters and battery systems from transient voltage spikes caused by nearby lightning strikes — a mandatory component for any system installed in a lightning-prone region. Free System Planning Service One of the most valuable features Portable Sun LLC offers is completely invisible in their product listings: a free system planning service staffed by NABCEP-certified solar technicians. Customers who complete the system planning form on portable-sun.com receive a comprehensive design proposal covering panel quantity, inverter sizing, battery capacity, string configuration, and wiring specifications — at no cost, and with no obligation to purchase. This service, which would cost hundreds to thousands of dollars from a professional solar installer, is provided free because Portable Sun understands that customers who buy the right equipment the first time are far more likely to become satisfied repeat buyers. What Customers Are Saying Across the DIY Solar Power Forum — where serious DIY solar builders share vendor reviews with unusual candor — Portable Sun LLC receives consistently positive feedback for several specific attributes: their per-watt panel pricing consistently benchmarks competitively against larger national distributors; their freight delivery is praised for speed (multiple forum members report pallet orders arriving within a week of placement); and their phone support team, particularly Faith who is frequently mentioned by name, is noted for being knowledgeable and responsive even for complex system questions. The consensus from experienced DIY solar builders is that Portable Sun is a reliable, honest supplier for large-ticket solar equipment purchases.
