V-TAC VT-603 600W 512Wh portable power station600W pure sine-wave power station, 512Wh LiFePO4, Wi-Fi

Overview

The VT-603 (V-TAC SKU 12705) is the compact entry model: 600W continuous and 1000W peak from two pure sine-wave AC sockets, backed by a 512Wh, 25.6V lithium iron phosphate battery rated for 3,000 cycles. Two USB-C ports deliver up to 100W, two USB-A ports 12W, plus a 126W car socket and two DC5521 outputs. It recharges at up to 600W from mains or 200W from solar, weighs 7kg and measures 301×227×193mm.

• 600W to 3000W pure sine-wave AC output
• 512Wh to 2560Wh LiFePO4, rated 3,000 cycles
• Solar input from 200W up to 2×800W
• AC bypass mode draws loads from the grid
• 1000W and 3000W models expand with up to 6 batteries
• Wi-Fi supported, 2-year warranty

How it works

Each power station combines a lithium iron phosphate battery, an inverter with pure sine-wave AC sockets, DC and USB outputs and several charging inputs. In inverter mode the AC sockets run from the battery; in bypass mode they are fed from the grid input while the unit is plugged in. The battery can be charged from mains, from solar panels through the PV input or from a 12V vehicle socket (12/24V on the larger models), and AC and solar charging can be combined.

V-TAC rates all packs for 3,000 cycles. The 600W and 1000W models use cylindrical steel-cased cells, the 3000W model and its expansion pack prismatic aluminium-cased cells. Charging power depends on the source: from 600W on mains for the smallest model up to 2100W for the VT-300011, which also accepts 2688W from mains and solar together.

Choosing a model

The VT-603 gives 600W (1000W peak) from 512Wh. The VT-10003 offers 1000W (1600W peak) and 614Wh and accepts up to six VT-614 expansion packs. The VT-10008 delivers 1800W (3000W peak) from 1229Wh. The VT-300011 provides 3000W continuous and 5000W peak from 2560Wh, two 800W solar inputs and an Anderson 30A output, and grows with up to six VT-25001 packs.

Use and care

The housings are IP20, so the units are for dry places. V-TAC gives the best operating temperature as 20–30°C; discharging works from -20 to +45°C and charging from 0 to +45°C, and storage between -20 and +45°C, preferably at 20–30°C. Car charger and DC5521 outputs share one 126W budget. Wi-Fi is supported for remote use, and the warranty is two years. The VT-614 and VT-25001 expansion packs have the same operating limits, 10–85% non-condensing humidity and a 2,000m altitude limit.
