  1. Thanks for accepting me in this invaluable forum! Came accross these :ARTsolar – 305 Watt Solar Panel – Mono Anyone out there had dealings with them and feedback on this panel? I like the fact that its a locally made product and their pricing seems good too!

  2. Bean-to-cup is most likely doing cycle skipping - where it would switch on one cycle and off for a couple. (If you pass 50Hz AC through a diode, it is still 50Hz. If you pass it through a full-wave rectifier, you get 100Hz. To get to 25Hz, you need a flip-flop )

  3. Yes, hair dryers usually have diodes on the heater on some settings - inverters do not like that. Straighteners usually have some form of control like a triac, but I do not have a lot of experience on them. Do an experiment - test if the hair dryer causes the sound on max heat and fan.

  4. The tests was done sperately, each item being the only item at the time of testing. Geyser (2.1kw draw) - barely any noise Kettle (1.4kw draw) - barely any noise Microwave (2.2kw draw) -barely any noise Big Geyser (4.6kw draw) - barely any noise Hair Dryer (1.7kw draw) - inverter hums a lot Hair Straightener (0.8kw draw) - inverter hums a lot It seems like there is sommin about those two "long hair" appliances that is difficult .... much like their operator

    Victron ESS proposal

    [sarcasm] Why is it that days with high power consumption correlates with cloudy days - and a serious loss of PV power - battery depleted by 11pm; while days with low power consumption correlates with no cloud cover and perfect PV power?

    No. You don't need it for any Victron install, even with the older inverters. It will work fine without it, but for a very specific kind of install. When you run ESS, the system tries to zero the part that comes from the grid. There are two possible ways to measure how much is being used from the grid. The one is to use an external meter (such as the Carlo Gavazzi, or with the Multiplus-II you can use the eternal current transformer). The other is to use the Multi's built-in current sensor on the input. If you use the latter option, then the Multi will zero it's own input. Only loads
