The Go Power! 1500 Watt 24 Volt Industrial Pure Sine Wave Inverter (model GP-ISW1500-24) converts 24 volt DC battery power into pure sine wave AC. It supplies 1,500 watts continuously and a 2,650 watt surge, with a dual GFCI outlet on the front panel for plug-in loads.
Go Power suggests it for larger loads such as a microwave, along with TVs, stereos, computers and other electronics, or as a source of emergency backup power. It suits 24 volt trucks, boats and RV systems. It's certified to UL 458 and covered by a 2-year Go Power warranty.
Harmonic distortion stays under 5% at normal load, giving appliances and sensitive electronics a smooth waveform like utility power. DIP switches on the front panel select 100, 110, 115 or 120 VAC and 50 or 60 Hz. Maximum efficiency for the 24 volt model is 92%.
On top of 1,500 watts continuous, the inverter supports up to 115% (1,730 VA) for one minute and a 2,650 watt surge for one second. A short circuit on the output triggers shutdown within one second.
With no load, idle draw is 1.0 A or less. Turn on Powersave with DIP switch 4 and it drops below 0.05 A until a load appears, with a front-panel dial to set the wake-up threshold. Loads take about one second to start in this mode. The manual says that's fine for steady loads like TVs and stereos but 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 includes dry relay contacts that switch on a fault, so you can wire in an alarm or an indicator light.
An internal fuse and protection circuits cover input over-voltage, under-voltage and reverse polarity, plus output short circuits, overloads and heat sink over- or under-temperature. The inverter alarms and shuts down at 21 V, restarts at 25 V and shuts down above 33 V. A temperature and load-controlled fan handles cooling.
Set the power switch to REMOTE and add Go Power's ISW Inverter Remote for 24V ISW inverters (GP-ISW-R-24). Go Power says it gives you on/off, a battery-voltage and output bar graph and fault indicators on a 25 foot cable. The simpler GP-SWR-A push on/off remote with an LED is also listed for this model.
24 volt trucks. Run a microwave, laptop or chargers from the truck's battery bank.
Boats with 24 volt banks. Power galley appliances and electronics, with the inverter mounted in a dry compartment.
Emergency backup. Keep electronics and small appliances running from a charged 24 volt battery bank when other power is out.
Go Power describes modified sine power as a stepped approximation that's fine for tools, lights and resistive loads but can buzz, run hot or damage sensitive electronics and some chargers. The GP-ISW1500-24 produces pure sine power for all of those loads.
Both deliver 1,500 watts continuous and a 2,650 watt surge from the same 16.59 x 9.76 x 3.27 inch case. The 12 volt model runs on 10.5 to 16.5 VDC with 91% maximum efficiency, and the manual calls for #2 AWG cable. This 24 volt model runs on 21 to 33 VDC and needs only #6 AWG. Neither is switchable, so order the one that matches your bank.
Go Power's model chart lists the GP-ISW2000-24 at 2,000 watts continuous and 3,500 watts surge, also with two GFCI outlets on 24 volts. Step up if you want to run a microwave plus other electronics at the same time.
Go Power estimates this inverter draws about 69 A from a 24 V battery at full load, and that a 100 Ah 24 V lithium bank runs it flat-out for roughly 83 minutes. Go Power's typical draws include a 32 inch TV at 50 to 80 W, a coffee maker at 600 to 1,000 W and a microwave at 700 to 1,200 W (1,000 to 1,700 W input). The manual lists #6 AWG copper cable and a 200 A inline fuse or circuit breaker for this model, with a combined cable length of 10 feet (3 m) or less and the fuse ideally within 18 inches of the battery. DC overcurrent protection isn't included, 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 and notes the GP-DC-KIT3 gives more margin for long runs.
Install it indoors or in a 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 it near the batteries but not in their compartment or directly above them, and mount it with the case horizontal, never vertical. Go Power recommends a professional electrician or RV or marine technician for the install. The manual states the inverter isn't intended for life support or other medical equipment.
Anything whose running watts stay under 1,500 and whose start-up surge stays under 2,650 watts. Go Power mentions a small microwave, a coffee maker, a hair dryer on low, power tools or several electronics at once.
Go Power's spec sheet names the GP-DC-KIT2 for the 24 volt model, and Go Power suggests the GP-DC-KIT3 for long cable runs.
Yes, the GP-ISW1500-12. This page is the 24 volt model, so confirm your battery voltage before you order.
Go Power warrants the GP-ISW1500-24 for two years against defects in materials and workmanship. The manual says opening or altering the unit voids the warranty.
The Go Power! 1500 Watt 24 Volt Industrial Pure Sine Wave Inverter brings 1,500 watts of pure sine power, a 2,650 watt surge and a dual GFCI outlet to your 24 volt battery bank, with Powersave draw under 0.05 A.
