   I have a large RV that I use primarily off grid. I currently have a 1200W pure sine wave inverter that runs most of what I need, but doesn’t support the microwave or air conditioner. I upgraded to this 5000W inverter and it has allowed me to use everything in the RV with no noticeable issues. This came well protected in a very heavy duty box. There was no meaningful marks or damage to the inverter or any of the accessories. It was also a straight forward swap for me, since I already had all the wires going into my existing inverter, and I plugged in a 10 awg extension cord, which supports up to 3600W continuously. I’ve pulled a little over 4000W through this inverter for short periods of time while running my AC and microwave, and it has worked properly. The display that shows my battery voltage and output voltage is accurate and helpful, and the remote also displays the voltage of the battery bank. I tested the low voltage cutoff and it works as designed, turning the inverter off at around 40.5V, which is safely above the low voltage cutoff of typical lifepo4 battery BMSs. I’m unable to test the quality of the sin wave, but it runs everything in my RV without issue. The idle/standby power was a concern for me, but luckily settles at a respectable 38-40W (the manual states 15W). This is an important metric as I’ve tested units that use upwards of 80W while providing no power at all, which for some off grid systems would be a burden since it’s always on. Cons: -I wish it had a wireless remote. The wired remote works well but it’s cumbersome to wire up. It’s standard telephone connector which is nice. -The cover over the hard wire connectors is flimsy and easily knocked off. This is easily worked around, however is annoying and potentially dangerous. In summary, this inverter was perfect for me needs of running the 120V needs of a medium/large RV. Like most inverters, I wouldn’t push it continuously at it’s max load of 5000W, but from my testing it appears to handle it fine for short bursts.
