5.13 CHARGER ONLY MODE
In Off-grid DC powered homes, for efficiency consideration, all lighting and other loads /
appliances are normally powered from 12V batteries that are primarily charged through
solar / wind power. Generator backup is used for powering AC to DC battery charger for
charging the batteries during extended periods of cloudy / no wind conditions. To meet this
requirement, the EVO
TM
can be programmed to operate as a battery charger ONLY. Details are
given below
When “Charger Only” Mode is selected (ONLINE MODE: 2=Charger Only), the EVO
TM
will
operate as a battery charger to charge the batteries and pass through the AC input power to
the loads as long as AC input is available (In DC powered homes, 120 VAC pass through will
normally not be used as all the loads will be DC)
When AC input fails, the Inverter Section will NOT be activated and the EVO
TM
will operate in
“Standby Mode” as long as AC input is NOT available. In “Standby Mode”, the EVO
TM
draws
extremely low power from the batteries (< 5W)
For further details, please refer to the following Sections of the EVO-RC Plus Manual:
• Section 4.1.3.1: Screen No. 13 of “Select Parameter Menu Map for Group 1 – CHARGE
CURVE” at Fig 4.2
• Section 4.4.2.13.2: “Charger Only Mode” under ONLINE MODE
