Go Power! 3000 watt Industrial Pure Sine Wave Inverter Features
It copies the exact power that comes from your wall.
This inverter produces a true pure sine wave the same clean power as your home outlet. Every appliance, tool, and device runs smoothly, safely, and at full speed without buzzing, overheating, or damage.
It runs any tool or appliance you plug into it.
With 3,000 watts of continuous power, this inverter handles refrigerators, power tools, TVs, computers, and more all at the same time. It's Go Power!'s biggest and most capable inverter for heavy-duty use.
It shuts itself off before anything gets damaged.
Built-in overload protection watches your power draw in real time. If things get too heavy, it safely powers down to protect both the inverter and your connected devices saving you from costly repairs or replacements.
It saves battery power when nothing is running.
Powersave mode puts the inverter into a low-power sleep when no devices are in use. The moment you plug something in, it wakes right up quietly stretching your battery life further between charges.
It works with your solar controller for hands-free power.
Pair the GP-ISW3000 with a compatible Go Power! solar controller like the GP-PWM-30. Your inverter will automatically turn on and off based on your solar system's charge no manual switching needed.
It fits almost anywhere thanks to its slim build.
The low-profile design slides neatly into RV compartments, under workbenches, and inside tight vehicle builds. It's built tough to handle vibration, heat, and everyday wear without taking up more space than it needs to.
It comes backed by a solid two-year warranty.
Go Power! stands behind this inverter with a two-year warranty, giving you peace of mind from day one. It's a long-term power solution built to last not a product you'll be replacing anytime soon.
