Go Power 300 Watt Pure Sine Inverter Review

I know this isn't really a common Inverter size for most people on this forum. Someone might find it useful.

Got the 300 watt Giandel pure sine moving ridge inverter in and wanted to test it. The premise was that if information technology really got 95% efficiency running low wattage items (< 100w) I could justify having this for small-scale loads and a 1500 watt Inverter for the curt duration/loftier wattage items.

The test uses...

• a deep-cycle battery
• running through the chapters tester Will recommends to measure DC watt hours fatigued from the battery
• through the Giandel Inverter
• through a Wemo Insight Smart Plug to mensurate Ac watt hours used.
• To a load using several light bulbs

The Wemo Insight is a marginally authentic device which fluctuates quite a bit. Instead of trying to get an instantaneous reading I ran the tests over many hours then that those numbers tin exist averaged using the watt-hours tallied over the runtime of the test. Makes for a far more accurate exam. Also... the Wemo draws some power to written report and Bluetooth that information to the Android app. In a separate test, I determined its usage rate at 1.78 watts.

Results

1. At 71 watts load, I measure 85.2% efficiency. IOW, information technology uses 83.3 watts from the battery.
2. 144 watts, 85.9%
3. 279 watts, 90.5%

Summary

• The lowest wattage efficiency was disappointing... in that marketing literature says "up to" 95% efficient. I was counting on a relative high efficiency at sub 100w rates to justify having two inverters. I will know better one time I test these numbers against the 1500 watt Inverter.
• The expert aspect, the Inverter was dead quite below 100 watt usage. The fan does not come on till over 100watts. Information technology uses passive cooling. The case leveled out at 95°F.
• Above, 100 watts, the fan comes on and eats into the Inverter's efficiency. The fan is non loud, but I actually don't have another Inverter to compare. I'd say its about as quiet every bit a desktop power supply fan. The case temperature drops to 78°F once the fan is going.

That's really good.

If information technology makes you feel any meliorate, my $2000 Victron 48/5kW is nearly 65% efficient at 71W.

Summary

• The lowest wattage efficiency was disappointing... in that marketing literature says "upwards to" 95% efficient. I was counting on a relative loftier efficiency at sub 100w rates to justify having 2 inverters. I volition know better once I examination these numbers against the 1500 watt Inverter.
• The expert aspect, the Inverter was dead quite beneath 100 watt usage. The fan does not come on till over 100watts. It uses passive cooling. The example leveled out at 95°F.
• Above, 100 watts, the fan comes on and eats into the Inverter'due south efficiency. The fan is not loud, but I really don't have another Inverter to compare. I'd say its nigh as quiet as a desktop power supply fan. The case temperature drops to 78°F once the fan is going.

Up to means the very best condition. Kinda like when you lot run into a sale in a store and they say "Up to 70% off". Except the only thing that is 70% off is the Orange Tuxedo in size XXS or XXXL.

All DC-DC or DC-AC converter efficiency ratings endure when lightly loaded.

For DC-DC the delta betwixt voltages makes a difference. Another thing to watch out for is increased noise when input voltage is the same as the output voltage. The converter goes into a discontinuous style (basically starts stuttering) when this happens and that creates additional electric noise.
