I am running my Multiplus II GX 5kVA with 3 Pylontech US3000C batteries + 4kW solar to power a small pottery kiln during load shedding (2 hours). The kiln draws 4500W, but is powered on/off by a kiln controller with pulse width modulation switching with a 70 % duty cycle. Based on the limits described in https://www.youtube.com/watch?v=4SXtGIx0x5w I think I'm within the limits.
Everything works, but I do get inverter overload warnings. I don't get alarms - only warnings.
My question is whether I'm going to eventually damage the inverter by doing this, or can I safely continue given that I'm only getting warnings and not alarms?
In my testing I have pushed the inverter to the point that it's gone into alarm mode and shut down for 30 seconds, so I'm assuming this mechanism will act as a safety catch before I can do any actual damage.
(I would obviously like to have a bigger inverter and more batteries to give more headroom, but I'm trying to use my existing system instead of spending a whole lot more on upgrading)
Many thanks
