Three Steps. That's It.
From unboxing to generating power in about an hour. Plug-in solar is as simple as setting up a new appliance.
Place
Position solar panels on your balcony railing, patio, backyard, or any sunny spot. No roof access needed — no drilling, no mounting hardware on the structure.
Plug
Connect the system to a GFCI-protected outlet. The built-in microinverter converts DC to AC and feeds clean energy into your home circuits. Most homes already have a suitable outlet — if not, a minor upgrade may be needed.
Save
Start generating your own electricity immediately. Your meter slows down, your bill drops, and with battery storage you also get backup power during outages.
Solar & Energy Storage Solutions Compared
Understand the key differences between plug-in solar, portable power stations, and traditional rooftop systems. Each serves a different need — and a different budget.
Plug-in solar pushes power into your home circuits through GFCI-protected wall outlets. Multiple plug-in solar units can mesh-network together for expanded capacity. The system reduces your utility meter in real-time and provides backup power during outages.
Why Plug-In Solar?
Four compelling reasons why plug-in solar is gaining momentum across the US — and why early adopters are already saving.
Energy Savings & TOU Arbitrage
Generate free electricity from sunlight — a typical 800W system saves $200–$600/year on your utility bill. With battery storage, you can also charge during cheap off-peak hours and discharge during expensive peak periods. In states with Time-of-Use pricing, this TOU arbitrage adds another $100–$700/year. Most systems pay for themselves in 2–7 years.
Backup Power & Resilience
With battery storage, keep your essentials running during outages — refrigerator, Wi-Fi, phone chargers, medical devices. The average US household faces 7+ hours of outages per year. Plug-in solar is the only backup power option that also saves you money every day.
Environmental Impact
An 800W plug-in system offsets roughly 0.5–1.0 tons of CO₂ per year — equivalent to planting 15–25 trees. Clean energy with zero emissions, zero noise.
Portable & Flexible
Take it with you when you move. No permanent modifications to your home. Start with one panel, add more anytime. Scale from 400W to 3,000W as your needs grow.
Two Benefits. One System.
Plug-in solar delivers value in two distinct ways — every day savings on your electricity bill, and backup power when the grid goes down. Here's how each benefit works.
Bill Savings
Every watt of solar power your system generates is a watt you don't buy from the utility. Your electricity meter slows down in real time — reducing your monthly bill by $15–$50 depending on your system size and local rates.
- →Offsets the most expensive peak-rate electricity first
- →Typical savings: $200–$600 per year for a 400–1,200W system
- →Payback period: 5–8 years at average US rates
- →Works best in states with high utility rates (CA, NY, HI, MA)
Energy Resilience
Add a battery to your plug-in solar system and you have stored energy ready when the grid goes down. Unlike a generator, it's silent, requires no fuel, and recharges automatically from your solar panels during daylight.
- →1,000Wh battery powers a fridge for 8–16 hours or a phone for 80+ charges
- →Recharges from solar panels during the day — no grid needed
- →Silent, zero-emission backup vs. noisy gas generators
- →Critical for renters who can't install whole-home backup systems

Retail Energy Companies
Bundle plug-in solar + storage with electricity plans. Reduce peak demand on your grid, increase customer retention, and create a new revenue stream.
Safety & Standards
Plug-in solar systems meet rigorous electrical safety standards. Here's what protects you.
UL 3700 is a new US safety standard specifically developed for plug-in grid-interactive power systems, covering anti-islanding, ground fault detection, overcurrent protection, and power quality. The standard is still evolving and currently undergoing revisions. Utah's HB 340 requires devices to be certified by UL or an equivalent nationally recognized testing laboratory — it does not specifically mandate UL 3700. As the standard matures and state legislation advances, certification requirements may become more specific. Check current requirements for your state before purchasing.
All grid-connected microinverters must meet UL 1741 standards for utility-interactive inverters, ensuring safe grid integration and anti-islanding protection.
If the grid goes down, the microinverter automatically disconnects within 2 seconds — protecting utility workers and preventing back-feeding. This is required by both UL 3700 and UL 1741.
Plug-in solar systems fall under NEC Article 690 (Solar Photovoltaic Systems) and Article 705 (Interconnected Power Production Sources). Systems below utility interconnection thresholds with anti-islanding protection operate within existing NEC provisions without requiring utility approval.
Plug-in solar must connect to a GFCI-protected outlet. Most modern homes have GFCI outlets in kitchens, bathrooms, garages, and outdoor areas — check if your intended outlet is already GFCI-protected. If not, adding a GFCI outlet is a minor electrical upgrade that typically requires a licensed electrician. For best performance and safety, a dedicated 20A GFCI circuit is recommended. Some state legislation may specifically require a dedicated circuit; check your state's requirements on the State Tracker.
Built-in GFCI protection monitors for ground faults and shuts down the system instantly if any leakage current is detected.
Because plug-in solar requires no structural or electrical modifications, most homeowner and renter insurance policies cover them as personal property.
Outdoor-rated panels and inverters are sealed against rain, dust, and humidity. Designed to operate safely in all weather conditions year-round.
