Have been looking at a few UPS/inverters and one of the interesting elements is the parasitic load (the load the inverter uses even if these is nothing connected to it). With a limited energy supply the choice of inverter can get interesting as to which one to use, at the moment I have a 2200VA UPS switched on 24x7 but I am realising that this is not going to work in winter (or when I don't have a surplus of power) because the UPS unit on it's own uses around 75W, which is nearly 2kWh per day or nearly half of my 24x7 equipment.
With this in mind, I'm trying to findan option that will work and has minimal wasted energy. My smaller 24V Belkin unit is very good, but limited load so wondering what route / inverter, ideally 48V...
This is my list so far... will update it
Make Volt Model Rated VARated W No Load use
APC 48V Tower 2nd Gen 2200VA 1980W 75W (approximate)
APC 48V 1U rack 3rd Gen 2200VA1980W 60W (approximate)
Belkin 24V ?? 2000's 650VA 350W ? 5W (approximate)
MGE 72V ?? old 3000VA 80W (approximate)
Eaton 36V Evolution 1550 1550VA 1100W 20W (need to measure again)
The limited power location is a 20ft container with solar on top and a small wind turbine closeby, so every watt counts...
