First UL 3700-listed plug-in solar kits reach US retailers
Three manufacturers received UL 3700 certification in February. Retail rollout begins in Q2, with prices ranging from $499 to $1,100 for complete kits.
What happened
UL Solutions confirmed on February 12 that three plug-in photovoltaic kits had cleared UL 3700 certification: two single-panel 400 W kits and one two-panel 800 W kit. These are the first products in the US market carrying the certification that HB 395 (and eight other state statutes) reference.
UL 3700 tests the entire product as one system — panel, microinverter, cable, plug — rather than certifying the components individually. That is the meaningful difference from UL 1741, the older rooftop-solar standard: a UL 3700 listing means someone tested that this specific panel, plugged into this specific microinverter, safely disconnects when unplugged.
The three kits
The manufacturers have asked the certifier not to publicize their names until retail listings go live, but the specs are on file with UL. All three kits share the same core characteristics: NEMA-6 outdoor enclosures, sub-second anti-islanding disconnect, and a standard NEMA 5-15 plug for connection to a 120 V household outlet.
Wattage and price differ:
Kit A: Single 400 W panel + 360 W microinverter, ~$499
Kit B: Single 440 W panel + 400 W microinverter, ~$599
Kit C: Two 440 W panels + dual-input 800 W microinverter, ~$1,100
Retail timing
Amazon and Home Depot have both confirmed to trade publications that they intend to stock UL 3700 kits within the calendar year. Specialty solar retailers (altE, Renogy, Signature Solar) are expected to list first, likely in March – April. Big-box arrival is more likely late Q2.
For Virginia buyers
A UL 3700 kit purchased today is legal to own and to plug in anywhere the owner controls the outlet — an owned home, a rented single-family house whose lease doesn't restrict it, or a balcony where the lease is silent. The HB 395 provisions that stop landlords and HOAs from restricting compliant systems don't take effect until January 1, 2027; between now and then, existing lease and covenant terms still govern.
