How long does the 1500w provide "surge" power? Is it sufficient to start a motor (e.g. refrigerator or furnace blower)?

The technical answer is one half second it will surge up to 3k. It pulls about 290 DC amps. So to get the full surge you need a 300 amp fuse. Yes it will start a furnace blower. My furnace on wall power or inverter takes 26 amps surge and 5 amps running. Anything beyond that 26 AC amps then the inverter shuts down due to overload.

The battery bank is the power supply so have good deep cycle batterys a lot of amps are needed to run this inverter. The 1500 watts is close to 15 amps of current for as long as the batterys can supply the current. The inverter supplys peak amps to start things up but for a short time only. You must always know the watts/amps of the load you run with the inverter as not to over load it or a fuse will blow and it will over heat. Inverters or made mostly for short useage as they eat up a battery fast. The surge power is only on start up as fast as you cut it on or the load pulls current then it normal power after that.

It is powerful enough to run a small rv refrigerator, I haven't actually pushed it to any limit. I currently have 1-50" Samsung LED TV, 1-32" Samsung TV, a Canon combo printer, a Playstatin 3 and a laptop running on it currently in a mobile office. And barely touching it's potential.

Ten months ago use this inverter and i can assure you that it is the best one i've ever had. You can start the fridge along with the lighting in my house and all electronic devices without any effort

I had a microwave running from it with no problem, even in the "defrost" mode which constantly is cycling on and off.

i don't know, i use it for xray processing, a lap top and it is connected to a deep cycle battery and works fine

I'm confident that the cord will handle that momentary surge, however, I would be more concerned about your power supply/generator being able to handle that surge.

I HAVENT used mine.,it wont start my refridgator.,,surge power is 5seconds.,take at 10seconds to start.. if you need surge power,,cant recommend this.

depends on who provides your power but 1500 watts is like running 15 100watt light bulbs. works well for our 18'x18' bedroom. cheaper than heating the whole house.

I have run a regular full sized stand up vacuum cleaner for several minutes with mine. There was no power surge or let up. Hope this helps.

Yes, This TF151W will supply power for your furnace, refrigerator ,etc. up to 1200 watts in the event of a power outage. with your generator.

Hello Peggy, If you Plan to use a load that surges to the 3,000 watt rating then you must use a 250 amp fuse or resettable circuit breaker for the Input side. This unit works well up to 1,000 watts It does not perform well on large start up motors like a Vacuum cleaner. I use this unit for small loads that require a pure sine wave. Mike

Full power would be speed setting 3, which my kill a watt meter measured to consume about 35 watts. Assuming you have consistent 120 volt outlets (sometimes they are a bit off, but that should not effect calculations too much), we get p=i*v. Plugging in: 35=i*120--> i=.3 amps. Again, using Tony's answer, worst case scenario the initial amperage pull when starting would be 1 amp, then it'd settle down to .3 amps. But when starting the motor I've noticed that it takes a few seconds to get up to speed so the initial pull shouldn't be anywhere near worst case.

The rule of thumb for motors is they will draw 3 to 6 times their nameplate current (depending on load). A vaccuum has no real starting load (much like a fan) so 3 times is typical. This in-rush current is short lived (mili-sesconds). It is very likley that a 5 amp motor will not overload the 900W inverter with 1800 watt peak. The only way to truly know is to test it.

Quite frankly, I am not really smart enough about surge watts and the like. I use my capacitor for a 230 volt 4 ton air conditioning condenser. So, I do not know if that relates what your situation is.

I've used X-10 appliance modules with 1500 watt space heaters for over 20 years but only for the 15 minutes I am in the bathroom in the morning. It's not really rated to handle that load so I wouldn't operate one unattended. And there's another rub. Space heaters have thermostats and the cycling of those thermostats will make an appliance module turn on without a command from you. To disable that problem, you must open the module and defeat local control (cut a jumper). If you aren't electronics savvy, you should not use this module for a space heater.

With this wattage you could do a couple of appliances. Like you could keep a fridge and/or freezer going. But you definitely need a bigger unit if you are looking to hook to the house for backup power.

Depending on what else u run with generator , it does not require many amps when running . A 3kw will be fine Maybe a lil surge when u first plug it in

It does, but unless there are circuit boards in your appliances, there is no need for surge protection. Motors of fridges and other large appliances handle surges just fine, typically. Surge protection is meant for finer electronics that cannot handle fluctuations. Large ac motors can just fine. And remember, surge protection is NOT lightning protection.

mine does fine on 15Amp breaker - there is a surge when you start first, but when it runs it runs - no problem

The 6,000 watt rating is for continuous use at 120V. Please not that the surge is not rated on this unit from generac, but never exceeds 10% running wattage. If you should have any further questions please contact me at 800.654.7440 ext 109 and I would be happy to assist with any further questions you may have!

I installed a small UPS like you would use for a computer. Gives me about 90 minutes of full load run time. When in standby, it uses little or no energy, so it will get me through most short outages where it's not worth the effort of hooking up the generator.
