Additional Details
The ST-VI150-12 is a 150 W, 12 V pure sine-wave vehicle inverter that converts a 12 Vdc battery supply to clean 220 Vac ±5% with THD ≤ 4% — suitable for running everyday appliances rated up to 180 W from a car, van or RV electrical system. At 90% efficiency it sustains a 150 W load even at 70 °C ambient, and its built-in micro-switch removes standby loss when no load is connected.
The unit operates from an 11–16 Vdc input with a maximum DC input current of 20 A and a no-load current of ≤ 300 mA. The 220 Vac output socket is mounted on a separate harness from the inverter body for tidy in-cabin placement, and the rugged IP5K2-rated enclosure handles a -40 to +85 °C operating range (derate above 50 °C) with quiet ≤ 40 dB running.
