Review: ` seems to be carefully designed, well constructed and working, fine.
Review: WOW, I’m impressed! It met all specs, 3000 Watts continuous AND 6000 Watts inrush. I did a full evaluation. Beautiful sine wave, not just at idle but also at full load (shown in picture). I tried circular saws, angle grinders, shop vacs and space heaters, right up to 288 DC amps input continuous with 25.38 amps at 119 vac out = 3020 watts! Fans come on when load increases and not overly noisy, less than 50 db @ 1 foot 19.9khz. Fan won’t come on immediately below 500 watts or until it gets hot. At 250 watts the fan may never need to turn on. An electric blanket or T.V. Probably won’t start the fan. The fans being on should be a subtle reminder that you are pulling power and using your battery. More specs; Weight less than TEN POUND! Frequency at idle 59.9 Hz and at full load 59.8 Hz. Idle current 24Watts or 1.8 amps. Indicated DC voltage is actually .050 lower than actual. Use a tie straps to secure the terminal protectors, don’t sandwich the plastic to attach the cable lugs. Provided cables are 50mm2 (equivalent to #1AWG) vinyl jacket makes it look bigger. This should be sufficient for most but it should be noted that it will get hot at sustained full rated load and will account for 1/4 volt loss at the inverter’s terminals when loaded and when the battery is low it could cause a low voltage shut down that little bit earlier. Since the inverter is so good for the price point I won’t take a star away. For a good install and any length of distance longer than cables provided, use 4/0 cables and 400 T class slow blow fuse and BlueSea holder. For LifePO4 batteries you will need; one battery with a high quality BMS rated at least 300 amps OR two batteries, each with 200 amp bms’s in PARALLEL to attain full power potential of this inverter. For lead acid perhaps one large battery (high cranking current) may work but it will be depleted much faster than lithium. Be sure to “pre-charge” before connecting even if it’s turned off. A simple filiment light bulb will work.

## Questions & Answers

**Q: Can it be used with solar panels?**
A: Of course, with solar panels, MPPTs and battery packs it is possible to form a stand-alone energy system with BELTTT inverter.

**Q: Is it easy to install?**
A: Mounting dimensions 17x7.7x3.9 inches, screw hole diameter 0.217 inch. Easy to carry and install.

**Q: Does it have a cooling fan?**
A: The inverter is equipped with two cooling fans and uses dual temperature and power control. It starts when the temperature reaches 122±41°F or the output power exceeds 600±150W.

**Q: What battery types work best with inverters (lithium vs lead-acid), and are inverters compatible with lithium batteries?**
A: The BELTTT inverter is compatible with 12V batteries like AGM, GEL, FLD, SLD and lithium batteries.

**Q: Can an inverter be wired directly to a truck battery and can a truck’s cigarette lighter socket be used for an inverter?**
A: The BELTTT 3000W inverter comes with 2 x 1/0AGW 3Ft battery cables and can be hardwired directly to a battery (including truck batteries). But it can not be connected via a truck’s cigarette lighter socket.

if you plan to put 10 awg stranded wire into the 30 amp holes, good luck. you will find already installed 15 amp and 20 amp receptacles, but you have to wire in the 30 amp and it is impossible without taking the inverter apart. a second problem is the DC in connections are oriented at 18 degrees from each other, so if mounting the inverter horizontally on a wall, you will be trying to connect one of the connections without being able to see the washers etc that you are trying to line up. i think i'd get a different inverter if doing it again just because of these issues.
