20 Most Recent Cobra ® Power Inverters Questions & Answers

it indicates an overload situation not enough information provided as to voltage supplied to the inverter and the voltage of the grinder examples are for 110 volts ac with a current draw of 4.2 amps the wattage is 462 watts or for 240 v ac with 4.2 amps the wattage is 1008 watts assuming that it is 240 volts and the inverter has a maximum ate of 1000 watts then it is overloaded and circuit protection is cutting in check the wattage of the inverter and the wattage of the ac units you use and if there is not a 25% difference in favour of the inverter then it is an overload situation

OLP or Over Load Protection means the device plugged into the inverter is over loading the the inverter please ensure the device you have plugged in is not rated to more than 2500w of power.

Sorry we do not have that detailed of info.

It's normal for some vehicles to have a fan run for a few minutes after the car is shut off, generally to keep the engine cool. However, if the fan is running for an extended period, the fan itself can become damaged due to overuse. ... It's possible you may have a module or relay failing in your car. https://watchonlinehub.com/kedarnath-2018-full-hindi-hd-movie-watch-online-free-download.html

Sadly the users manual offers just a few lines of troubleshooting... Mainly to make sure the cables are snug. If you don't have the manual try this: https://www.cobraelectronics.co.uk/media/Cobra-User-Manuals/CDR840E_MANL.pdf I tried! Anthony

As the Cobra 1500w inverter is constructed analogous to a high-frequency "switching" power supply, it is not recommended to modify it to exceed original specifications. For any inverter intended for applications exceeding 2000W transient peak, it is highly recommended to use a low-frequency "true-sine" inverter. Your Cobra inverter is designed for low-deman applications, and is insufficient for high-demand applications.

Probably faulty from factory. I would return it

Is this new or old? Sounds like it been over heated. If you can return it I would

I don't know the model you have but green usually means it's on an working. Red means you have a voltage overload or it got to hot an needed to shut down until it cools off. Hope this helps

Any auto parts store will have it. Possibly even Walmart depending on if it is specialty. Do you still have the old ones that you're trying to replace?

ONLY if the inverters are designed to be "stacked." Some are, but they tend to be expensive. It's usually cheaper to just buy one that has enough ampacity to run the appliance in question.

You may not have adequate input voltage. And unless you are hooking up to a forklift battery, the battery will not have adequate current delivery capability for any more than a few seconds at full power of the inverter.1200 Watts is 100 Amps. 1500 Watts is in the neighborhood of 130 Amps.

60 amps times12 volts = 720 watts times 80% effic of conv. = 576 watts available for microwave...

You must have a very tiny microwave as most require at least 1000 watts input power. That might have something to do with blowing the fuse. Since the microwave has a very reactive inout, you need a goodly safety margin above the rated watts input.

It sounds like the fan is failing.
Good Luck,

It appears to be something to do with this https://www.google.com/search?q=keb+12f5+that+shows+E.EF+external+fault 7.13.1.6 External fault With Pn.04 "Ext. fault input selection", one or more digital inputs can be programmed which can trigger the error "31: ERROR! External input" (E.EF). With Pn.03 "E.EF stopping mode" , the response of the inverter to the digital input is defined. With Pn.65/ bit 1 "2: Pn.04 = E.UP https://www.keb.su/doc/Instrukciya%20F5-A_E_H%20ver.4.0%20(ang.).pdf ..

Back in 2014 it wasn't so easy. Laptop with an HDMI port and a smart television with HDMI. ..

I have a quiet cool roof top air conditioner and am looking for parts for it.
