The Go Power! 700 Watt Industrial Pure Sine Wave Inverter (GP-ISW700-12) converts 12 volt DC battery power into pure sine wave AC. It delivers 700 watts continuously, up to 810 watts for 1 minute and a 1,230 watt surge for 1 second. 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 designed it as a mid-range inverter for travel trailers, boats and fleet trucks. It suits TVs, stereos, computers and most medium-load electrical equipment. The housing measures 13.00 x 7.87 x 3.27 inches and weighs 5.73 pounds.
The GP-ISW700-12 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. The inverter is certified to UL 458 (6th Edition) and FCC Class B, and maximum efficiency is 91%.
The inverter supplies a 1,230 watt surge for 1 second and handles 100% to 115% of its rating, up to 810 watts, for 1 minute. That headroom helps devices that pull extra power for a moment when they switch on.
With switch 4 on, the inverter turns itself on and off as it looks for a load, drawing under 0.1 A instead of up to 1.5 A at no load. A dial on the front sets how large a load wakes it up. Go Power notes a one-second delay before a load starts, which is fine for TVs and stereos but may not suit intermittent loads such as bread makers, power tools or blenders.
Three LEDs on the front show input voltage level, output load level and fault conditions. The voltage LED glows green from 11.5 to 15.0 V, orange from 11.0 to 11.5 V or 15.0 to 15.5 V, and red below 11.0 V or above 15.5 V.
An RJ-11 remote port on the back accepts Go Power's optional GP-SWR-A or GP-ISW-R remote. A 6-pin green terminal block adds a Form C dry contact relay that switches on a fault, so you can wire an audible alarm or an LED indicator. The same block has enable terminals for remote on and off, using 20 to 24 AWG wire.
The inverter sounds a low-voltage alarm and shuts down at 10.5 V, then restarts at 12.5 V. It shuts down at 16.5 V and restarts at 14.5 V. An internal fuse protects against reverse polarity, the output shuts down within 1 second of a short circuit, and over and under temperature protection works from heat sink temperature at 80°C and -20°C.
Travel trailers and RVs. Run a TV and a laptop together from your 12V house battery bank.
Boats. Power electronics from the house bank, with the inverter mounted in a dry compartment.
Fleet trucks. Run computers and medium-load equipment from the truck's 12V system, and wire the fault relay to an alarm or indicator light.
Go Power's GP-800HD is a modified sine inverter rated 800 watts with a 1,600 watt surge, and Go Power positions it for power tools, lights and blenders, not sensitive electronics. The GP-ISW700-12 gives up some wattage but delivers pure sine power for TVs, stereos and computers.
The GP-ISW1500-12 steps up to 1,500 watts continuous with a 2,650 watt surge, and Go Power suggests it for a small microwave, a coffee maker and tools. If your loads stay within 700 watts, the GP-ISW700-12 handles them in a smaller, lighter package.
Go Power recommends #6 AWG copper cable and a 110 A Class T fuse for the GP-ISW700-12. 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 lists the GP-DC-KIT2 install kit for this inverter. The inverter is 12V only, and reversed cables can damage it and void the warranty.
Install it indoors or in a dry compartment, 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. It is rated to operate from -4°F to 104°F (-20°C to 40°C).
Anything whose running watts stay under 700 and whose startup surge stays under 1,230 watts. Go Power mentions a TV and laptop together and small kitchen appliances. Its typical draw estimates put a 32 inch TV at 50 to 80 watts and a blender at 300 to 600 watts.
Go Power estimates the inverter draws about 65 A from a 12V battery at full load. By that estimate, a 100 Ah 12V lithium bank runs it at full output for roughly 89 minutes.
No. Go Power states that this inverter is not intended for use with life support equipment or other medical equipment or devices.
Go Power lists two. The GP-SWR-A gives you on and off with a status LED. The GP-ISW-R adds bar graphs for battery voltage and output power plus fault indicators. Set the inverter's main switch to REMOTE before you use either.
Go Power warrants it for 2 years against defects in materials and workmanship.
The Go Power! 700 Watt Industrial Pure Sine Wave Inverter gives your 12V system 700 watts of UL 458 certified pure sine power with a 1,230 watt surge, an adjustable power saving mode, a GFCI outlet and remote and relay connections. If you'd like help sizing cable, a fuse or a battery bank for it, the Outbound Power team is happy to help.
