SunGold Power 4000W DC 12V Pure Sine Wave Inverter With Charger Delivers Pure Sine Power, Built-In Charging, and Auto-Transfer So That Your Home, RV, or Off-Grid System Stays Running No Matter What

When the grid goes down, the campground hookup disappears, or you're running power tools fifty miles from the nearest outlet, you need more than a basic inverter. You need a complete power management system. The SunGold Power 4000W DC 12V Pure Sine Wave Inverter With Charger is exactly that a low-frequency powerhouse that combines a 4,000-watt pure sine wave inverter, a multi-stage smart battery charger, and an automatic AC transfer switch into one intelligent, rack-ready unit. Whether you're backing up your home, outfitting your RV, living off-grid, or running a mobile worksite, this LFP Series inverter charger is built to handle the heavy lifting and the everyday essentials, simultaneously and without complaint.

At Outbound Power, we specialize in portable and backup power solutions for people who depend on reliable electricity whether you're at home, on the road, or completely off-grid. Our team understands these systems because we live and breathe them. If you have questions about whether this inverter charger is the right fit for your battery bank, solar array, or generator setup, we're here to help you get it right the first time.


SunGold Power 4000W DC 12V Features

It pushes out 12,000 watts of surge power for 20 seconds.

Big appliances like air conditioners and refrigerators need extra power to start up. This inverter handles that surge without tripping or shutting down, so your equipment starts smoothly every single time without any hiccups.

It delivers clean pure sine wave power that protects your electronics.

Pure sine wave output works just like wall outlet power from your home. Your laptops, medical devices, and smart appliances run safely without buzzing, overheating, or damage giving you total peace of mind every day.

It automatically starts your generator when the battery runs low.

You never have to babysit your power system again. When battery voltage drops, the inverter starts your generator on its own. Once charging is done, it shuts it off — completely hands-free and worry-free.

It switches between AC and battery power in just 10 milliseconds.

The built-in transfer switch moves between power sources almost instantly. Most electronics won't even notice the switch happened. This keeps your devices running without restarts, lost data, or annoying flickering lights.

It lets you adjust the charging current from zero to full power.

You control exactly how fast your batteries charge. Turn it down for smaller generators or turn it up for large battery banks. This flexibility protects your generator and maximizes your charging efficiency every time.

It supports nine different battery types with a smart three-stage charger.

Whether you use AGM, flooded lead-acid, or lithium batteries, this charger knows exactly how to charge them correctly. The three-stage process extends battery life significantly, saving you money on replacements over the long run.

It comes with an LCD screen, remote control, and temperature sensor.

You always know what your power system is doing. Check voltage, load, and battery status from across the room using the remote. The temperature sensor automatically adjusts charging to keep your batteries safe in any weather.
