LiTime is the brand of Shenzhen Ampere Time Digital Energy Technology, founded in 2018 and renamed from Ampere Time in December 2022.
It sells direct from litime.com, which ships US orders from warehouses in Los Angeles and Dallas, and through its Amazon store and Walmart's marketplace.
The LiTime L12V2KW-INV-ATS-Z is a 12 V pure sine wave inverter rated 2,000 W continuous and 4,000 W peak surge, with 110-120 V AC output at 60 Hz (plus or minus 3 Hz), efficiency of 90 percent or more, a 10.5 V to 16.0 V DC input window, and low- and over-voltage protection at 10.5 V and 16.0 V. Its built-in automatic transfer switch takes grid or shore power at 90 to 144 V AC through its own AC input breaker, passes it straight to the loads while the grid is up, and switches the loads to battery within 20 ms when the grid fails; it does not charge the battery from the grid. The AC side has two AC outlets, a high-output L/N/G hardwire terminal block, a ground terminal, a 5 V 2.4 A USB-A port and a USB-C port rated 5 V 3 A, 9 V 2 A and 12 V 1.5 A; two temperature-controlled fans cool it, and it operates from -4°F to 104°F. It measures 14.17 x 7.42 x 4.02 in with its mounting feet (12.68 x 7.42 x 3.94 in without) and weighs 8.71 lb. The box holds two 1.64 ft (50 cm) battery cables, a 3.28 ft ground cable, the LCD remote with a 14.76 ft cable and two clip-on brackets, and screws and anchors for the remote and the inverter. LiTime publishes no no-load draw and names no GFCI, and its warranty policy and product page give it a 2-year warranty. It sells singly; LiTime's 2000 W 12 V inverter without the transfer switch is a separate product.
