To clarify my rating, the quality of construction is excellent. I gave it a bad rating due to the observed performance. The claim to provide 5KW output for 5 MS is at best deceptive in that a 3500W sinusoidal signal will have a peak of 5KW, but the worst part is that when the inverter thinks it is overloaded, the fundamental output is greatly reduced while high frequency components greatly overwhelm it. 3KHz is dominant but it does not turn off with the overload light on. Contrary to the description, this inverter does put troublesome RFI on the AC power and battery lines. Without additional filters 1 volt peak erratically timed ringing impulses with frequencies to 7 MHz appear on my lead battery. Laird LF cable cores on the wires attenuates these substantially. There seems to be a design problem with shutdown described below. I am largely guessing because I can’t get the documentation to say if I am right or wrong, but my suggestion for turning it off is to disconnect the load then the DC input which will activate the low voltage shutdown with minimum stored energy on the input capacitors. This should minimize the chance of failure. I observed two problems on shutdown by just turning the switch off: 1) First time there was a loud sharp pop and a arc, and a little smoke near the front of the inverter which is where the DC to AC converter is. I could not find any damage and cannot explain what happened. The inverter worked when I turned it back on. 2) Later there was a long sizzling pop and much more smoke and one of the MOSFETs in the 24V to 200V converter blew apart.. Product is under warranty but returning it to factory in China will cost at least $88. Manufacturer gave me a partial schematic but the soldered in cards that provide MOSFET driving signals was not included. I was offered a replacement MOSFET ($2 value) and told that the driver card rarely fails. My guess is that there is no shutdown gating and that different MOSFETS will shut down at different times due to their varying Vgs thresholds if they are not matched (and I was not offered a matched set of 4). That could cause the transformers they drive to saturate with the result I observed.Read full review

I purchased this inverter several months ago, which they claimed to have shipped on April 2, but I have not received it after 2 months/ I have emailed them several times with no response. I am about to file a complaint with E-Bay. The price seemed to be much lower than competing products, but is meaningless if they never ship the inverters. I had hoped that this was real, but very disappointed in their questionable practices..

The unit arrived quickly (24V model) and does work but for a rated 2400W continuous and 5000 Peak it barely starts a small electric chainsaw. I have a 12VDC 1800 Watt unit that does the saw just fine. If you have anything other than electronics to run I would not recommend this unit.

Bought the same 2500W inverter in July and is has worked fine running our off-grid house. We only use 2-2.5KWh per day, running lights, small refridgerator/freezer, top load washer, laptops etc. I try to be easy on it but I did use a circular saw a few times. Bought this again as a backup since they are low cost and we get a lot of lightning.

I have been through two of these now. I am using them for solar. The seller replaced the first one I bought for an additional $80.00. They don't hold up when running a large load (800watt portable AC). As soon as I switch it on now, it will immediately blow my 75A terminal fuse. Not safe. I would recommend paying more for a quality inverter, as these are cheaply made.
