Re: Charger and monitor power draw
A charge controller like the MX60 must be connected to batteries to operate. Similarly, the OutBack FX inverters must be connected to batteries in order to operate. The off-grid inverter will disconnect downstream AC loads if the battery voltage drops to a threshold setting. The batteries must then be recharged from a PV array via the MX charge controller, or from the FX inverter’s built-in charger and a generator. Monitoring systems typically don’t draw much power, and they should continue to operate for a while. But, taken to the extreme, everything will eventually turn off if the batteries are completely drained.
The MX60’s standby (“sleeping”?) power consumption spec is “< 1 W”. This spec is included in the controller’s spec sheet as well as in its user manual. Its “tare” loss while operating is ~10 W, IIRC.
FX inverter idle power is ~20 W. This can be reduced if the unit is placed into a “search” mode or put to “sleep”. The idle and search specs are included in the controller’s spec sheet, and, IIRC, the sleep power spec is buried in the user manial.
