Review: So far, this inverter really shines! - Exceptionally well-built, without the number one cause of failure related to design flaw - using bolted wiring lugs. This one has proper soldered metal tabs that are securely soldered directly to the circuit board for the battery wires, which prevents high resistance in the battery input from developing as the lugs heat up and cool down, expanding and contacting until the internal connections where the wires bolt on the back of the lugs come loose and add massive amounts of resistance. This is what caused the fire that resulted inside my last inverter (you can find my review of that one with photos of the internal wiring that melted and caught fire in my other reviews here). The way the tabs on this inverter are soldered directly to the board instead of using knurled twist connectors like many others do relieves my fear of another fire. The battery cables bolt on with actual bolts to the exposed side of the tabs, and have hard plastic shells that prevent short circuits in the battery cables where they go into the converter housing. This is MUCH safer than the lugs with wires bolted on the inside that then connect to the circuit board. The display that comes on the face of this unit, and the one on the remote switch are clear, easy to read, and not so bright that they'll keep you awake at night. They also have useful information for quick-glance occasional checking of the battery voltage, AC output voltage and a bar graph for current load. They also show either "OK" when the system is functioning normally, and fault codes for errors such as over voltage, overload, and other possible faults. Intuitively, the face of both readouts has fault code explanations right on the panel so you'll never have to go looking through drawers trying to find the owner's manual to know what went wrong if you get an error, and can use the information immediately to correct the fault. This speaks very highly of the design. Installation was very easy, and due to the type of transformers this inverter uses, it's just over half the weight of many comparable inverters. One of the best things about this inverter is that when the red push-button switch on the face of the inverter (and the remote switch if connected) are in the "off" position, there is NO current draw, so you don't get the typical arcing that occurs with many of the inverters in this price range, and don't have to use a resistor when connecting your battery to prevent huge sparks. This is a huge safety bonus for lead acid battery setups as that spark could lead to an explosion if your battery is off-gassing when you make that connection. So far, I'm quite impressed. I tested the system using a 300ah lithium iron phosphate battery to power the inverter, and running a 10,000btu home air conditioner plugged directly into one of the inverter sockets. The inverter didn't even stumble, powering the air conditioner for over an hour. The fans turned on immediately when the load was applied, rather than waiting for the inverter to heat up, which again is safer than units which turn the fans on in response to heat after it occurs. This kept the heat on the outside of the inverter down to only 24f above ambient temperature. The fans are also about as noisy as an electric toothbrush, (and far less irritating). As for longevity, only time will tell. But we're off to a great start so far, and for the reasons already mentioned, I already feel confident that this inverter was designed to perform well, and to last. If anything changes, I'll change my review to reflect the changes. If you're reading this review and it's still showing 5 stars with no updates, it's still performing as stated.
Review: Well Built Inverter - I bought this inverter to use in my camper, and I'm glad I bought it, although now I'm wishing I had bought their 3000-Watt model so I could power more appliances like the coffee pot or vacuum cleaner. I will most likely buy that one and use this one in my truck in the near future. That said, It's an extremely well-built inverter for under $100. As it is, this inverter is great for smaller appliances and electronics. I've run my KOIOS air purifier with it, my laptop and TV with no issues. I've got it hooked up to a general lead-acid battery at the moment which is kept charged with two 100-watt solar panels, and it’s working fine. I had a partly-sunny day yesterday, and I used the inverter for several hours without depleting my battery. I really like the ease of installation and the high quality and workmanship that went into this inverter. The LED display is really nice, so you can see at a glance your DC input, power output, error codes and battery level. The power connection in the back is great, not those stupid knobs that other inverters have. These are bolts with nuts and washers that do a MUCH safer and more reliable job. I also like the included grounding block mounted on the side. To wrap up, the BELTTT brand is impressive. Well built, easy to install, functions well, is SUPER quiet, is mountable so it travels fine, and makes a great addition to my camper to use during power outages or just to help offset the electricity that I use with shore power hooked up to my camper. I wish I had gone ahead and bought the 3000-Watt model, but that’s on me. I recommend this product.
