The Go Power! 1000 Watt 24 Volt Industrial Pure Sine Wave Inverter (model GP-ISW1000-24) turns 24 volt DC battery power into pure sine wave AC. It runs 1,000 watts continuously, with a 1,750 watt surge to help start motors and compressors, and feeds your loads through a dual GFCI outlet on the front panel.
Go Power designed it for work trucks, fleet vehicles, boats and 24 volt RV systems. It handles TVs, laptops, a coffee maker or a small microwave and most other medium loads. It's certified to UL 458 and backed by a 2-year Go Power warranty.
Harmonic distortion stays under 5% at normal load, so electronics and small appliances get a smooth waveform like utility power. Front-panel DIP switches select 100, 110, 115 or 120 VAC output and 50 or 60 Hz. The 24 volt model reaches 93% maximum efficiency.
Beyond its 1,000 watt continuous rating, the inverter supports up to 115% (1,150 VA) for one minute and a 1,750 watt surge for one second. A short circuit on the output triggers shutdown within one second.
Idle draw is 0.8 A or less with no load. Switch on Powersave with DIP switch 4 and it falls below 0.06 A while the inverter waits for a load to appear. A front-panel dial adjusts the wake-up threshold. Loads take about one second to start in this mode, which works for steady loads like TVs and stereos, but the manual cautions it may not suit bread makers, power tools or blenders.
Three LEDs report input voltage, output load and fault status. A 6-port green terminal on the DC end provides dry relay contacts that change state on a fault, so you can add an audible alarm or an indicator light.
The inverter guards against input over-voltage, under-voltage and reverse polarity with an internal fuse, and against output short circuits, overloads and heat sink over- or under-temperature. It alarms and shuts down at 21 V, restarts at 25 V and shuts down above 33 V. A fan controlled by temperature and load handles cooling.
Set the power switch to REMOTE and plug Go Power's optional GP-SWR-A or GP-ISW-R remote into the remote port. The GP-SWR-A adds an on/off switch, an LED status light and 25 feet of cable, so the inverter can stay near the batteries while you control it from the cab or cabin.
Work trucks and fleet vehicles. Run laptops, chargers and other medium loads from a 24 volt system on the job.
Boats with 24 volt banks. Power electronics and a coffee maker, with the inverter mounted in a dry compartment.
24 volt RV systems. Run a TV, laptop or small microwave from the house batteries.
Go Power describes modified sine power as fine for tools and lights but able to buzz or damage sensitive electronics. The GP-ISW1000-24 delivers pure sine power, so it can run TVs, laptops, microwaves and chargers along with simpler loads.
The two share the 1,000 watt continuous rating, 1,750 watt surge and 14.65 x 7.87 x 3.27 inch case. The 12 volt model takes 10.5 to 16.5 VDC and peaks at 92% efficiency, and the manual calls for #4 AWG cable for it. This 24 volt model takes 21 to 33 VDC and uses #8 AWG cable. Neither can be switched between voltages, so match the model to your battery bank.
For the GP-ISW1000-24, the manual lists #8 AWG copper cable and a 110 A inline fuse or circuit breaker, with a combined cable length of 10 feet (3 m) or less. Put the fuse as close to the battery's positive terminal as you can, ideally within 18 inches. The inverter doesn't include DC overcurrent protection, and a battery disconnect switch is required unless a circuit breaker serves that role. Go Power pairs the 24 volt model with the GP-DC-KIT2 install kit, which includes the Class T fuse, fuse block and 10 foot battery cables. Go Power estimates the draw at about 45 A from a 24 V bank at full load.
Choose an indoor spot or dry compartment with air between -4 °F and 104 °F (-20 °C and 40 °C) and at least 4 inches of clearance around the vents. Keep the inverter near the batteries but out of their compartment, never directly above them. Mount it with the case horizontal, never vertically. Go Power recommends a professional electrician or an RV or marine technician for the install, and the manual states the inverter isn't intended for life support or other medical equipment.
Any load whose running watts stay under 1,000 and whose start-up surge stays under 1,750 watts. Go Power lists TVs, laptops, a coffee maker or a small microwave and most medium loads.
Go Power names the GP-DC-KIT2 for the 24 volt model. It includes the Class T fuse, fuse block and 10 foot battery cables.

Go Power covers the GP-ISW1000-24 for two years against defects in materials and workmanship. Opening or altering the unit voids the warranty, according to the manual.
The Go Power! 1000 Watt 24 Volt Industrial Pure Sine Wave Inverter brings 1,000 watts of pure sine power, a dual GFCI outlet and very low Powersave draw to your 24 volt battery bank, with UL 458 certification. If you'd like help choosing the install kit, remote or cable sizes, the Outbound Power team is happy to help.
