I have 48V and 24V version, and both have same problem, load can't reach 2100W, othervise inverter shut-down output and output power will be recovered only when load is decresed under this value. So 5000W with 10000W peak power is really big joke. On board are 2paralel 10A fuses with 4 transformes so 40Amps max = 3840W on 48V version, but software will shut down it when load is above 2100W.. If you OK with this, it's good inverter, with low self consutpion, with little bit slow feedback when load change..

good sound and range of power supply.. I tried different speakers and everything is good.. except.. delay.. Time of sound decode is too high.. more than 500ms and it's easy to recognize it. If you use it without video source, nothing happend.. but with video it's bad. Someone start to speak and you hear it with delay. I tried difeerent modules and did not had this problem (BT 4.1) this device has BT 4.2.. so I problem ist in hw codec or somewhere. Power consuption is really low. With small speakers at 4ohms at 25% of power, lass than 2W.
