I’ve compared every major US-market plug-in kit against the same savings model we use in our billing work. The market is still small compared to Germany, but the product options are finally usable. The wrong kit is usually the one with no listed microinverter certification, not the one that’s $200 more.
Compare these kits against your state's electricity rate and sun hours. Our calculator shows payback and 10-year savings for each size.

Every kit on this list needs three things:
- A UL 1741 SB-listed microinverter (minimum). Full UL 3700 system certification is coming but rare as of mid-2026. See our UL 3700 explainer for what that means.
- A GFCI-protected outlet on a circuit with headroom for the inverter load.
- Legal clearance in your state. Seven states have enacted plug-in solar laws; others are gray area. Check the state law tracker.
Avoid no-brand Amazon bundles where the inverter manufacturer is unclear. The microinverter is the safety-critical part.
Quick comparison
| Kit | Watts | Price (approx.) | Battery | Best for |
|---|---|---|---|---|
| Bright Saver Flex | 400W | $499 | No | Smallest starter, renters testing the concept |
| PluggedSolar 800W | 800W | $799 | No | Ready-to-plug DIY, Amazon-friendly |
| CraftStrom 800W | 800W | $2,031 | No | Zero-export meter included, no utility signup |
| EcoFlow STREAM 800W | 800W | $899 | No | App monitoring, integrated design |
| EcoFlow STREAM Ultra | 800W | $1,899 | 1.92 kWh | Highest self-consumption, WFH households |
| Hoymiles DIY 800W | 800W | $750 | No | Best value if you assemble panels + inverter yourself |
Prices shift with promotions. EcoFlow’s STREAM microinverter has listed as low as $299 during launch promos. Treat table prices as mid-2026 street estimates.
Bright Saver Flex 200/400W
Price: ~$399–$499 for a single flexible 220–400W panel with integrated microinverter.
Bright Saver is a California nonprofit focused on renter-accessible solar. The Flex mounts with zip ties or railing hooks. No electrician required for the kit itself, though they offer optional install in the Bay Area and LA.
Pros: Lowest entry price, simple one-panel setup, designed for apartments.
Cons: Single panel means modest output (roughly 350–500 kWh/year in California). You will want a south-facing railing with no shade.
My take: Best if you want to prove the concept before spending $800+. At California’s 33¢/kWh average, a 400W system saves roughly $80–$120/year depending on self-consumption.
CraftStrom 800W
Price: ~$2,031 for four 200W bifacial panels, two 350W smart inverters, smart power meter, and cabling.
CraftStrom has sold roughly 2,000 systems since 2021, mostly in California, Texas, and Florida. The differentiator is the zero-export smart meter at the breaker panel. It throttles inverter output every 0.1 seconds so excess power never backfeeds to the grid. That removes the utility interconnection conversation in practice.
Pros: Most complete US-native system, 10-year warranty, zero-export design, ETL/UL-certified inverters.
Cons: Highest upfront cost among mainstream kits. Installation of the power meter may need an electrician depending on your comfort with the panel.
My take: The kit I’d recommend for a homeowner or long-term renter in a high-rate state who wants the fewest regulatory headaches. Payback at 28¢/kWh: roughly 5–6 years on $2,031.
PluggedSolar 800W
Price: ~$799–$1,100 on Amazon or direct.
Four 200W panels, UL 1741-certified micro grid-tie inverter, WiFi monitor, 50-foot cord. Ships as a complete kit.
Pros: Accessible price, Amazon distribution, UL-listed inverter, no subscription.
Cons: Mounting hardware quality varies. You are responsible for a safe railing or ground mount.
My take: Solid middle option for DIY buyers who want a name-brand inverter without CraftStrom pricing. Verify the specific listing’s UL documentation before ordering.
EcoFlow STREAM Series
Price: STREAM microinverter ~$599 (promotional pricing has hit $299). STREAM Ultra with 1.92 kWh LFP battery ~$1,459–$1,899.
EcoFlow’s US push started in 2025. The STREAM microinverter supports up to 1,200W AC output from two panel inputs and plugs into a standard NEMA 5-15 outlet.
Important caveat: As of mid-2026, EcoFlow markets plug-and-play solar for Utah specifically under HB 340, with expansion planned as more states enact laws. If you are outside Utah, confirm current shipping and legal guidance before buying.
Pros: Clean industrial design, strong app, battery expansion path with STREAM Ultra.
Cons: Utah-focused sales policy, premium pricing vs. DIY component builds.
My take: Good fit for Utah residents or early adopters who want an integrated ecosystem. Pair with our Utah plug-in solar law guide for the rules.
Hoymiles / APsystems DIY builds
Price: ~$750 for 800W (two panels + HMS-800 or EZ1-LV microinverter).
Not a single-SKU kit, but the most common path for price-sensitive buyers. Hoymiles HMS-800-2T ($150–$250) and APsystems EZ1-LV are widely available through US distributors with UL 1741 SB listing.
Pros: Best $/watt, proven microinverters, expandable.
Cons: You source panels and mounting separately. No zero-export meter unless you add one.
My take: What I’d build for myself if I already owned basic tools and a drill. Not ideal for someone who wants one box to open and plug in.
Kits to skip in the US (for now)
Anker SOLIX balcony kits: Popular in Europe. Anker’s dedicated balcony products are not UL-certified for US grid-tie use as of 2026. Anker sells other solar products in the US, but do not assume the European balcony SKU is legal to plug into a US outlet.
Generic Temu/AliExpress microinverters: No UL listing, no anti-islanding guarantee. Not worth the insurance risk.
Enphase balcony system: Available in Germany. No US balcony product announced.
Which kit for which situation
| Your situation | Kit I’d pick |
|---|---|
| Renter, first try, California | Bright Saver Flex |
| Renter, 2+ year lease, high-rate state | PluggedSolar 800W or Hoymiles DIY |
| Homeowner, want zero-export | CraftStrom 800W |
| Work from home, away-from-grid-evening usage | EcoFlow STREAM Ultra |
| Utah resident | EcoFlow STREAM or PluggedSolar |
| Lowest possible cost | Hoymiles DIY 800W |
Enter your state, monthly kWh, and facing direction to see which of these kits pays back fastest where you live.
