NOVOPAL 2000W Power Inverter

Keeps my freezer running at night to take come load off my generator

I bought this product for the many outlets and it came with a coupon vs its competitors. I've been using it for a few weeks now, installed in my car and have had no problems. I attached a 100 amp breaker just to be safe but I doubt I'll ever pull that much power. The remote's a neat feature but for my use, not necessary. Overall I'm satisfied and would recommend this.One thing I should mention is the cables it came with seemed a bit too small. So i swapped those out for some 8asw cables.

I purchased two of these units for a portable shelter for a military application. The first one is working flawlessly. The second one was determined to have an open ground. I am in process of sending this one back and have purchased another which works fine. These units have a good amount of power to drive a wide variety of equipment. Basically if it has an electrical plug, it will drive it. (you may not be able to plug 4 high power consumption units in at once).

I use this product to supply uninterrupted electricity to my computer, sewing machines and other electronics using some solar panels and flooded batteries. So far, after two months use I have no issues, computer works 24/7, never goes off, without power issues or failures. It is completely noise free. I even purchased a second one for my daughter's system. I recommend this item.

Update: Worthless! Zero stars! Don't waste your $. As noted below, this unit radiates huge amount of noise and RFI/EMI interference. The company had NO response to this and no "fix". I don't even think this unit could possibly pass FCC rules for RFI/EMI radiation. After months of trying, I was unable to reduce ANY RFI with up to 13 chokes on both the input and outputs. There is no way to fix it; don't waste your money, time, or wits!This unit causes massive RF interference, spraying out WATTS of RF interference across the entire LF, HF and into the VHF radio bands. The unit transmits a dead carriers and whistles across all bands with huge screaming noise across the entire spectrum.I installed EIGHT ferrite cores on the solar input lines, the AC outlet cable and DC input lines, and grounded everything. NO IMPROVEMENT. The AC power cable has SIX --double looped-- ferrite chokes plus a bypass capacitor; none of which helped cut the RF interference. I would think much of the HIGH standby current is used spraying WATTS of interference on the air. I can't imagine the FCC would approve such a poor design. DO NOT BUY THIS UNIT if you or anyone in your region have radio communication. This unit wipes out all receivers! Tech support was worthless.

I reviewed and seen it was a sine wave unit which was imperative to me with a modest cost.One thing to watch, the unit I bought was 24v which I actually like, but requires 2 batterieshooked in series.

I purchased this inverter to use in a solar / battery installation to operate amateur radio equipment, computers, and possibly a room air conditioner. Here is what I discovered:1. Even though this device is rated at 4000 watts surge / 2000 watts continuous, it will not start an 800 watt air conditioner.2. The spurious radio frequency emissions from this device sprayed +40db noise from DC to 50 MHz and probably beyond rendering the unit completely unusable for use anywhere near radio equipment.3. The user manual did not show any FCC or UL certifications. There is no way this device would pass FCC Part B certification. I am not sure how this device is legal to be sold in the United States.4. I e-mailed my concerns to the support e-mail address and received no reply whatsoever.5. If the room air temperature exceeds 95F, no matter how lightly loaded, the inverter shuts down. Since I live in Texas with 20-30 days a year over 100F, this device will not work in my garage or on a work truck either.The only use case where this device can operate is in an air conditioned environment with loads at least 1200 watts below the minimal rating and you have no need to listen to any radio equipment. I gave the rating 2 stars because it has 4 outlets where most inverters only have 1 or 2.I will start the return / refund process today because this device cannot serve me in any way. I now know to look carefully for FCC Part A and B certification.

Like how it works but not a 120 or split 110 /120 like it was supposed to be so I wouldn't recommend it for big things
