When we turn on the microwave or water heater, each draws about 1200w, 2 out 3 times the Multiplus shuts down with a Low Battery Alarm. The voltage shown on the Alarm message on the Venus GX display ranges from 14.51v to 12.37v -- see photo below, there does not appear to be low voltage. The ripple gets to 1.0 -- see video below. The shutdowns seem to be getting more frequent. Most of the time the Multi does not revive itself and has to be switched off and on. Getting lots of sun (over 1000w of solar power) does not seem to make any difference. Everything is running the latest software.
