The Go Power! 400 Watt 24 Volt Industrial Pure Sine Wave Inverter (GP-ISW400-24) converts 24 volt DC battery power into pure sine wave AC. It delivers 400 watts continuously, up to 460 watts for 1 minute and an 800 watt surge for 1 second to help loads start. A dual GFCI outlet sits on the front panel, and a DIP switch sets the output to 100, 110, 115 or 120 VAC at 50 or 60 Hz.
Go Power built it for work trucks, fleet vehicles, boats and 24V RV systems that need clean power for laptops, TVs, game consoles and other small electronics. It is a 24V only model, so check your battery bank before you order. The 12V version is the GP-ISW400-12.
The GP-ISW400-24 produces a pure sine wave with total harmonic distortion under 5% at normal load. Go Power describes pure sine wave as the same clean power as a wall outlet, while a modified sine inverter can make sensitive electronics buzz or fail.
Many devices pull extra power for a moment when they switch on. This inverter supplies an 800 watt surge for 1 second and handles 100% to 115% of its rating, up to 460 watts, for 1 minute.
Typical efficiency is 89%. Switch 4 on the front DIP switch turns power saving on, which cuts the draw to under 0.1 A, compared with under 0.5 A at no load with power saving off.
The front panel carries a North American dual GFCI outlet. Go Power lists the inverter as certified to UL 458 for the GFCI receptacle version, with FCC Class B EMC certification.
A single status LED glows solid green in normal operation and uses orange and red blink patterns with beeps to flag overload, over or under temperature, over voltage and under voltage. The inverter sounds an under-voltage alarm at 21.0 V and shuts down if the voltage keeps falling, then restarts at 25.0 V. It also shuts down on high input voltage and within 1 second of a short circuit. A fuse protects the input against reverse polarity.
The front rocker switch has ON, OFF and REMOTE positions, and an RJ-11 remote port sits on the back panel. Go Power pairs this inverter with its optional GP-SWR-A remote, so you can switch it on and off from the cab or helm.
Work trucks and fleet vehicles. Charge laptops and run small electronics from a 24V truck system.
Boats. Power a TV or devices from a 24V house bank, with the inverter mounted in a dry compartment.
24V RV systems. Run a TV, a game console and chargers without a large inverter.
A modified sine inverter puts out a stepped approximation of AC. Go Power says that is fine for tools and lights but can make sensitive electronics buzz or fail. The GP-ISW400-24 puts out a true sine wave for TVs, laptops, consoles and chargers.
Both are rated 400 watts with an 800 watt surge in the same housing. The 12V model accepts 10.5 to 16.0 VDC with 88% typical efficiency and under 1 A at no load. This 24V model accepts 21.0 to 32.0 VDC with 89% typical efficiency and under 0.5 A at no load. The voltage is not switchable, so match the model to your battery bank.
The GP-ISW200-24 uses the same housing with a 200 watt rating, a 250 watt surge and 91% typical efficiency. Choose the GP-ISW400-24 when a TV and a laptop might run together or a device needs a bigger startup surge.
Go Power recommends #8 AWG copper cable and a 40 A inline Class T fuse or circuit breaker for the GP-ISW400-24. Place the fuse as close to the positive battery terminal as possible, ideally within 18 inches, and keep the combined cable length to 10 feet or less. DC overcurrent protection is not included, and every install needs a battery disconnect. A circuit breaker can serve as both. Go Power pairs this inverter with its GP-DC-KIT1 install kit. Check polarity before you connect, because reversed cables can damage the inverter and void the warranty.
Install it indoors or in a dry compartment, away from rain, snow and other fluids. Mount it close to the batteries but not in the same compartment, and never directly above them. Leave at least 4 inches of clearance around the vents, and mount it horizontally, never vertically. Go Power rates it to operate from -4°F to 104°F (-20°C to 40°C).
Anything whose running watts stay under 400 and whose startup surge stays under 800 watts. Go Power lists laptops, TVs, game consoles and other small electronics.
Go Power estimates about 19 A from a 24V bank at the full 400 watt load. Keep the inverter close to the batteries and use the recommended cable gauge.
No. Go Power states that this inverter is not intended for use with life support equipment or other medical equipment or devices.
Plug the GP-SWR-A into the RJ-11 remote port on the back panel, then set the inverter's main switch to REMOTE.
Go Power warrants it for 2 years against defects in materials and workmanship.
The Go Power! 400 Watt 24 Volt Industrial Pure Sine Wave Inverter gives your 24V system 400 watts of UL 458 certified pure sine power with an 800 watt surge, a GFCI outlet, a power saving mode and remote capability. If you'd like help sizing cable, a fuse or a battery bank for it, the Outbound Power team is happy to help.
