Mastervolt Mass Sine Inverter (24V / 5000W / 50Hz)The Mastervolt Mass Sine power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. It is compatible with the Mastervolt MasterBus system, allowing it to be connected and configured centrally on the EasyView 5 alongside other items in your electrical system.

Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. It is compatible with the Mastervolt MasterBus system, allowing it to be connected and configured centrally on the EasyView 5 alongside other items in your electrical system. It can also be operated by the remote panel, or on the device itself. The power inverter can give you consistent, 24/7 use, with an MTBF (Mean Time Between Failures) of 180,000 hours when at full capacity without stopping. The Mass Sine range are extremely efficient and also feature an automatic economy mode, allowing digital clocks to carry on working whilst not putting excess strain on the battery. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming.

Great not only for TV Backlighting, but shelf lighting too!
Color: Black, Color: Black
Right off the bat, these light bars are vibrant, colorful, and have a great variety of different colors and patterns. However, I used them for a little bit of a different purpose than what they were created for...
I had previously purchased the TV backlight strips from Govee, and wanted to find lighting for my shelves within the Govee ecosystem. Traditional light strips wouldn't really work unless I spliced them, which I wanted to avoid. Enter these light bars. I bought 2 sets of them, and thanks to the (quite strong) mounting options, was able to mount and angle these lights downwards to create a really cool effect over my displays.
I wasn't sure how well it was going to work, but the end results speak for themselves. It looks terrific when used in this role. The cables are very long and manageable too, I was able to run them down the support beams of the shelves with some mounting clips without issue.
The only negative comes down to the app itself. It's a bit overwhelming and confusing to use at first, but once you get the basic functions figured out, there's little issue. Still, I feel the user experience could be improved on the app. For example, I had to go in and create my own shortcut function to turn on all my lights at once, then make a separate one to turn them all off at once, as opposed to there being a single master on/off button in the app. It's small things that can make the app tedious to work with.
Regardless, I feel that overall Govee continuous to knock it out of the park. The lights are bright, customizable, and add a ton of ambience to the room. I hope Govee continues to expand on their different room lighting options and keep the level of quality they are putting out now.

Looks good, feels good for my pocket.
Good price, while still being stylish. Slots fit all my major items shown above and now I cannot live without it.

Great purchase
My husband loves this so he has a place to put his phone wallet and keys and always knows where they are. Great idea! Small, keeps you organized, solid, good looking and gets the job done!

Cool piece
My messy night table looks clean for a few nights, then junk just piles up on top of this tray. But that might just be a me problem
