I've had this thing offline for over a year now. 540Ah batteries, 1200W panel and so on. 6000W peak power is no joke. This summer I built an outhouse and ran the compressor, chainsaw (worm drive), cut-off saw, saw blades, etc. with no errors! If you try to start the compressor and use the special saw it will sometimes shut down and the compressor will clearly struggle, but I'm sure this is above its rated capacity. The only thing I noticed about this device is that it is only charging. approx. 400W (measured with a Victron battery monitor). 30*24=720W, so don't charge as fast as possible. Incidentally, a solar charger reaches a charge of 1000+ watts from time to time. Everything indicates that this is a very reliable device that does its job very well. I took the lid off and there are some potent ingredients in there. Definitely built to withstand the pressure. Update 12/07/2020: I bought it on 08/24/2018 and installed it shortly after. Since then it has grown strong.
