Victron Energy 1200VA 12-Volt 120V AC Pure Sine Wave Inverter- NEMA 5-15R

Excellent build quality . Works beautifully as advertised. Can also operate remotely through the Bluetooth ( if you have the optional Bluetooth adaptor installed with the device - to be purchased separately ) , Seems pure sinewave because nor harmonic distortion on audio devices, No absolute sounds, Great value for money , sturdy. Overall , worth every penny. Very satisfied

I am very impressed with this inverter . It puts out clean, pure sine wave power at 118 volts . Good for electronic devices .

Works well for my needs. Sips energy in the eco mode when connected to a kegerator. That mode doesn't work for something like an ego battery charger that doesn't call for power constantly when it needs it.

Take note this inverters rated at 90% efficiency at most all loads which is exceptional. A 100 watt load running a blower style fan resulted in the unit not heating up and no internal fan noise on a 80 degree day. I was able to power a 6.3amp 120 volt half inch hammer drill with this (used on concrete without any issues.) I have the inverter on some 8 gauge wire to a 100ah Lithium Iron Phosphate battery. It would not however run a typical 10amp saw and alerted me of tripping the overload (auto reset was prompt and automatic.) With the victron bluetooth adapter connected to the unit the APP lets me select the status of the inverter on / off / eco no matter what the switch position is set to eco / on etc. Additionally the app lets you set output AC voltage +/- from 120 vac for finer tuning of the output which was an unexpected feature. This is a solid product and I am confident it can handle 500 watt draw sustained and can briefly take a peak temporary starting load of about 950-1000 watts this is important for motors and drills. I would advise getting the 1200 watt version if you want to run a microwave or a table saw but make sure you have a battery bank capable of supplying 150-200Ah loads. If you want to run a gaming laptop or macbook pro for editing videos on the go save the money and go with the 250VA option it should do just fine and give more mounting options due to the smaller case size. Quick update. I was able to run a constant 400 watt load of florescent lighting. The unit ran warm and fan was cycling (fairly quiet.) The 8 gauge wire for this kind of constant load is ok for a short time less than an hour but wire was very warm to the touch. Definitely use 6 gauge wire (max it officially supports) or adapt it to utilize 4 gauge during install with some car amp power cable adapters.

Easy install and everything works great. I tested it with 4 30w chargers, a 60w shop light, a small oscillating fan, and a 32” tv. Worked great. I did notice if I had it on eco mode and just the tv plugged in it would shut off and not turn back on. I think it won’t power back on unless it senses at least 14va, and powers off if it’s less than 10va. Overall I’m very happy, dead silent and perfect for my usage. I do think it’s more expensive than it needs to be, but I trust this company. I also find it annoying I had to buy a Bluetooth adapter.

Victron quality in a very reliable, easy to install inverter. This unit barely makes any noise since the fan rarely runs, and when it does it is quieter than most models in its size range. Some units are just too noisy ...this one just hums along with its heavy transformer construction.

First impression was not good: The box I received was not sealed, and the inverter had an acrid "hot electrical" odor when removed from the box. Both made me worry it was a used/broken and returned item. However, I saw no evidence of any original tape/seal, so perhaps the factory just doesn't seal the boxes. The inverter looked brand new on the exterior, with no scuffs or other signs of usage. Removing the cover reveals a large, heavy-duty toroidal transformer and sturdy frame, with plenty of air space between components. Board construction and wiring was neat and clean, and components all appear to be of good quality. Everything looked pristine inside, with no signs of overheating or burning, so I still have no explanation for the acrid odor. The molded plastic cover appears durable, though I would have preferred aluminum. I connected the inverter to a 12v source (2x 60AH AGM in parallel) and tested with various loads. It exhibited a good sinewave on scope and near perfect 120V regulation, both at idle and under load. The lower-priced options I tried before had pretty bad sine wave distortion under load and voltage droop to 110V, but the Victron output is excellent in all regards. The documentation indicates 4.2W consumption with no load, but I measured closer to 7W, so the unit should definitely be turned "off" when not used to avoid battery drain. I briefly tested Eco-mode, and it reduced the no-load consumption to the stated 0.8W. I connected the inverter to a variable supply to test alarms and cutoffs. The unit comes pre-programmed with the low-voltage alarm (not audible, just a red LED) at 10.9V and shutdown at 9.2V; both worked as programmed. High voltage cutoff is stated as 17V and is not programmable; the unit shutdown at 16.9V in my test. Note that 9.2V for low voltage cutoff is pretty low and could result in battery damage, so most users will want to change this to a higher value. The pre-programmed values for low voltage cutoff, low voltage alarm, eco-mode, restoration voltage, etc., can be customized through the VE.Direct connection. Unfortunately, this requires a proprietary USB cable or Bluetooth dongle that adds even more to the already high price. I purchased the VE.Direct Bluetooth dongle, connected it to the inverter, and downloaded the iOS app for my iPhone. The app quickly found the dongle, connected to the inverter, and told me there was a mandatory firmware update. Firmware was updated to v1.27. The iOS software works well; while not entirely intuitive, it is easy enough to figure out. The software correctly displays the input voltage AND output load (in VA) for me (some earlier reviews indicated problems with this, so perhaps firmware has been fixed). Overall, the software is well designed works very smoothly. The internal cooling fan is PWM controlled and remains off with low loads. When it did run, I found it pretty loud in a quiet room. I had hoped to have it in the bedroom when sleeping, but I think it would wake me up every time it cycled. Of course that is not an issue if the inverter is located in another room, or if there is other noise-producing equipment louder than the fan in the room. To summarize, this is a premium, well-built, programmable inverter that mostly justifies its higher price. Unlike the cheaper products I tried, the Victron actually lives up to its claimed output wattage with a clean sinewave and great voltage regulation. The fan noise may be problematic in some situations, and Victron could have used a standard USB connection for programming rather than requiring an expensive, proprietary cable or Bluetooth dongle. But if the price, extra cable/dongle purchase, and fan noise are not obstacles, this is a solid inverter that does what it says and appears made for a long service life.

I purchased this inverter to use on my boat for charging my cell, tablets, and to power a Starlink mini.It was easy to install. So far I have used it to charge phone, tablet and cordless vacuum. Worked flawlessly and is super quiet. Although this inverter is more expensive than others out there, its a quality product and we'll worth the extra money. I recommend this product.

Lo usé para alimentar módem y antena starlink y un mesh Google wifi. Funciona perfectamente

Altamente recomendable, buena calidad

Muy, pero muy buen Inversor, se auto protege cuando detecta una sobre carga, claro que lo recomiendo.

Es un producto totalmente confiable, fácil de usar altamente recomendable

El día de hoy pusé en funcionamiento este inversor de Victron con capacidad de 500 VA a 12 VCD.. Está conectado a una batería Ampere Time de 200 Ah. La carga es una computadora con su monitor y una lampara de leds de 7 W, en total una carga que oscila entre los 64 y 144 W (que dependen del trabajo realizado por la computadora). Se presenta un sonido que me recuerda mucho al que hacen los discos duros antiguos al estar leyendo o escribiendo. El sonido es casi constante y muy molesto, no se diga cuando llegan a entrar los ventiladores. Grabe el sonido en el video que anexé, donde se ve que la carga es muy pequeña y ese sonido muy molesto, incluso parpadea la lámpara al ritmo de ese ruido. Ya removí la lámpara y el sonido no cesa. Así que o es el Inversor o una falla del mismo. Muy mal producto para el precio tan elevado que tiene.
