ProMariner TruePower Plus 1000W Pure Sine Inverter

The ProMariner TruePower Plus 1000W is a pure sine wave inverter with a 30A transfer switch, GFCI outlets, USB and a digital LCD.

Pure sine wave is the specification that separates this from the modified sine wave models alongside it in the range. Sensitive electronics, audio and video equipment and anything with a switching power supply need clean AC. Modified sine wave makes them buzz, run hot, or refuse to work at all.

The built-in 30A transfer switch routes shore power to the connected loads automatically when it is available, so the inverter is not a separate system to switch between. That makes the AC outlets live whether the boat is on shore power or on batteries, without anyone deciding which.

A dual-color digital LCD message center shows AC output and DC battery information, with GFCI outlets and a USB port on the face. Soft-start filtered technology and double-rated surge capability handle demanding startup loads, and it ships with a separate On/Off remote on a nine-foot cable, DC cable covers and AC strain reliefs.
