Victron Phoenix Inverter 12/1200 120V VE.Direct GFCI

Victron publishes an honest derated figure — 1,000W at 25°C, 850W at 40°C — where most brands quote only the headline number. UL 458 certified with a published certificate.

Victron is the brand marine and off-grid electricians reach for, and the reason is visible on the data sheet: it publishes what the inverter does at 40°C, not just at laboratory temperature. Most competitors quote one number and let you discover the derating yourself in August. The UL 458 certification is real and documented, with the certificate itself published on Victron's own site — worth noting that the listing specifically covers the GFCI-equipped versions.
