Best Plug-In Solar Kits (2026): Top 8 Compared

EcoFlow STREAM is the plug-in solar line from EcoFlow, a company better known in the US for portable power stations. The STREAM Microinverter converts panel output to 120-volt AC and plugs into a NEMA 5-15 or 5-20 outlet. Its specification lists three MPPT inputs with four pairs of PV terminals, up to 450 W per input, 1,200 W of total input and 1,200 W of nominal output. It weighs 11 lb, carries a NEMA 6 rating and has a 10-year warranty. EcoFlow states UL 1741 certification with anti-islanding, overcurrent and overvoltage protection.

EcoFlow estimates up to 2,409 kWh a year and up to $385 of savings from one microinverter, based on 5.5 hours of daily sun and the average US electricity rate. Third-party panels with MC4 connectors can be used if they stay within 16 to 60 volts and 14 amps per input.

The product page carries two statements on where it can be used. A note says plug-in installation is permitted in Utah, Maryland and Colorado. Its footnotes say that, under Utah's H.B. 340, the product is sold for plug-and-play installation only in Utah. EcoFlow also recommends that buyers without net metering choose STREAM Ultra with a Shelly Pro 3EM meter instead of the microinverter alone.

EcoFlow STREAM Ultra combines a lithium iron phosphate battery with a built-in grid-tied microinverter in one unit that plugs into a NEMA 5-15 or 5-20 outlet. EcoFlow lists four MPPT inputs taking up to 2,000 W of solar, 1,200 W of on-grid AC output, a NEMA 4 rating, a net weight of about 23.1 kg and a 10-year warranty. The battery is rated at 6,000 cycles to 70% capacity.

One unit holds 1.92 kWh. Owners expand storage up to 11.52 kWh by plugging more Ultra units into wall outlets, which EcoFlow describes as AC coupling. Two AC outlets on the unit supply appliances directly, and in an outage the stored power is reserved for those essential loads. STREAM Ultra also accepts the STREAM Microinverter and, per EcoFlow's FAQ, third-party microinverters through its NEMA 5-15 outlets.

The EcoFlow app adds AI time-of-use scheduling that charges from solar or off-peak power and discharges at peak rates, and some AI features need a premium subscription. As with the microinverter, the page notes plug-in installation as permitted in Utah, Maryland and Colorado, while its footnotes limit sale and plug-and-play installation to Utah under H.B. 340.

CraftStrom is a Houston, Texas company that sells complete plug-and-play solar kits. Every kit combines its own panels, 400 W class smart inverters, a Smart PowerMeter, mounting hardware, connector cables and an AC cable for a standard outlet, with app monitoring.

The 800 Watt Eco-Line kit uses four 200 W Shield Series panels, each 59 by 28 inches and 24.7 lb. Its inverter specification lists 350 W peak output at 120 V with ETL certification to UL 1741 and IEEE 1547. CraftStrom estimates up to 1,440 kWh a year for the 800 W kit and up to 2,160 kWh for the 1,200 W version. Panels, inverters and PowerMeter each carry a 10-year warranty.

The PowerMeter is the defining part. CraftStrom states it regulates output every 0.1 seconds so the system does not back-feed the grid, which is why the company says no interconnection agreement is needed. It also describes the meter as protecting the input circuit from overload, which it calls breaker masking under UL 3700, and it describes the kits as UL 3700 compliant. Buyers who later want storage can add CraftStrom's 1 kWh battery towers and off-grid inverter.

Bright Saver is a 501(c)(3) nonprofit that sells balcony solar kits and campaigns for plug-in solar legislation. Its kit uses one or two lightweight, glass-free 180 W panels, each 46 by 34 inches and 11 lb, and one 360 W Hoymiles HiFlow Pro LV microinverter with a 15-foot cord and a monitoring app. Bright Saver states the microinverter carries a 12-year warranty and is UL 3700 compliant.

The 360 W ceiling is deliberate. Bright Saver explains that the electrical code leaves a 20% buffer on a 15-amp, 120-volt circuit, which equals 360 watts, so the kit fits within existing headroom. It asks buyers to use a GFCI outlet and cautions that interconnection rules vary by state, permits may apply and exported power may not be paid for.

Members pay cost price and the page itemises that cost: panels and inverter, fulfilment and shipping, payment processing and allocated overhead. The organisation says it will republish the table if costs change, and that its next shipment arrives in mid-October. It does not ship to New York, Maine or Vermont, stating that those states' laws require whole-system certification that no system has yet achieved.

Mango Power, better known for home batteries and power stations, sells the Mango Power S PIPV kit as its 120-volt plug-in solar product. The kit has four 300 W panels with N-type TOPCon cells, each paired with its own microinverter. Mango Power's specification lists 280 VA nominal output per microinverter, 97% CEC efficiency, an IP68, Class II double-insulated enclosure and a 25-year warranty on panels and microinverters. The company cites CA Rule 21, UL 1741-SA and SB, IEEE 1547:2018 and CSA C22.2.

Mango Power estimates about 6 kWh a day in good weather with five peak sun hours, and $420 of annual savings at $0.18 per kWh. The kit ships in four boxes with stands and cables. The included Smart Gateway Lite is a 200-amp meter that Mango Power says limits export to the grid within 200 milliseconds.

Mango Power states that, under Utah's H.B. 340, the kit is approved for plug-and-play sale and installation in Utah, where no utility approval is required. In other states that allow zero-export configurations, it says the system can be used after interconnection approval, electrical inspection and installation of the gateway. The system does not support off-grid use.

PluggedSolar is a US seller of plug-and-play and grid-tie solar kits, sold through its own store and an Amazon storefront. Its plug-and-play kit pairs two or four panels with an 800-watt microinverter, a 50-foot cord for a 110/120-volt outlet, a plug-in Wi-Fi power monitor and optional roof or ground mounting.

Buyers choose from 100, 150 or 200 W panels. The largest configuration uses four 200 W panels, each about 4.4 by 2.2 feet. PluggedSolar describes the microinverter as UL 1741 compliant for anti-islanding protection and states that the kit needs no additional wiring or battery. Installation takes two steps in its description: connect the panels in series to the inverter, then plug the cord into the wall with the power monitor.

PluggedSolar estimates about 600 kWh a year from 300 W of panels, 1,200 kWh from 600 W and 1,600 kWh from 800 W, which it equates to up to 20% of an average home's electric bill. The store also lists larger grid-tie kits of 1.2 to 3 kW described as plugging into an existing outlet. Those sizes exceed the 1,200-watt limit set in Utah and Virginia, as reported by Utah Public Radio and Canary Media, so buyers need to check the rules where they live.

APsystems is a microinverter maker founded in Silicon Valley in 2010, with US offices in Austin, Texas. The EZ1-LV is its plug-in microinverter for balconies, patios, gardens and portable setups. One unit connects two panels through independent MPPT inputs, supports modules from 315 W to more than 660 W each, and delivers up to 900 W of continuous AC output at 120 volts. It has built-in Wi-Fi and Bluetooth for the AP EasyPower app, a Type 6 enclosure and a 12-year warranty.

APsystems states the EZ1 is CSA certified to UL 3700 and meets UL 1741 SB requirements. Its anti-islanding protection shuts the unit down during an outage and restarts only after grid power is stable. Owners can adjust output in the app to align with local rules. An APmeter, sold separately, adds zero-export control so generation stays on site.

The EZ1 is sold without panels or racking, and APsystems also lists partner kits. Its FAQ says that while the hardware supports plug-and-play, the National Electrical Code generally requires a dedicated branch circuit for permanent solar installations, so eligibility depends on the local jurisdiction.

Hoymiles is a microinverter manufacturer whose HiFlow Pro LV series is its plug-in product for North America. In a July 2026 release from Richardson, Texas, Hoymiles described HiFlow Pro as the first plug-in microinverter compliant with UL 3700, the North American safety standard written for plug-in PV systems.

The series covers five models rated at 360, 391, 420, 450 and 500 VA, each serving one panel. The datasheet lists 95.5% peak efficiency, a NEMA 6 and IP67 enclosure, 2.4 GHz Wi-Fi and Bluetooth for the S-Miles Home app, a 15-foot plug-and-play cable and compliance with UL 1741, UL 3700 and IEEE 1547. Up to four units combine into one system of 1,200 W, which Hoymiles estimates at 2,403 kWh a year.

Hoymiles lists safety features aimed at plug-in risks: compatibility with GFCI outlets, shutdown within 135 milliseconds when grid power is lost or the plug is removed, voltage at the plug reduced to 34 V or less within one second, and breaker masking mitigation. It warns against power strips and extension cords. With a compatible meter such as the Shelly Pro 3EM, the system can limit export. Hoymiles does not publish a US price, and its US buy page links to Bright Saver.
