APPENDIX A
Solar Charge Controller is also connected to the External Charging Terminals (
3, 4 in Fig 2.1 of Owner’s Manual for
EVO-2212/3012/2224/4024),
the internal AC Charger will limit the charging current as follows:
Value of charging current produced by EVO
Charging Section
=
(Programmed value of charging current set by
parameter “BULK CURRENT”
(Section 4.4.2.1)
minus
(Value of current fed from the external solar
charge controller)
Under the following conditions, “Charging Mode” will be terminated, and the EVO will switch back to “Inverting
Mode”
(Switching from “Charging Mode” back to “Inverting Mode” has 2 options under programming parameter
“ONLINE OPTION” - see Section 4.4.2.14 for details)
:
i. When the batteries have been re-charged either fully through complete, 3-Stage Charging algorithm
(Parameter “ONLINE OPTION” set at “0= Option 1” - See Section 4.4.2.14)
or
,
ii. When the batteries have been recharged for a sustained programmed time period set by programmable
parameter “GEN OFF DELAY”
(0-240 min; Default 60 min” – See Section 4.4.2.17). [Parameter “ONLINE
OPTION” set at “1= Option 2” - See Section 4.4.2.14].

INFO
On-Line Mode is suitable for installations where both Grid and Photovoltaic (PV) Solar Battery Charging System
are available. It is also desirable in areas where Grid / Utility Energy Rates are very high and use of supplementary
battery based photovoltaic power system is more cost effective.
For various display screens under this mode, refer to Fig 3.3(a) to (d)
4.4.2.13.3 Option: “2=Charger Only”.
In Off-grid DC powered homes, for efficiency consideration, all lighting and other loads / appliances are normally
powered from 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™ can be programmed
to operate as a battery charger ONLY
i.e. when AC input power is
available within the programmed limits of voltage and frequency, charging will take place and AC input will be passed
through to the load(s). The unit will NOT transfer to Inverting Mode if AC input fails or is outside the programmed limits
of voltage and frequency.
(Refer to Section 3.8 regarding Menu Map for operating Mode Screens during this mode)
• 19 scrollable Operating Mode Screens for Charging Mode will be displayed
(See under Column 4 – “GROUP 3:
CHARGING MODE” in Fig 3.2)

As mentioned above, when the AC input fails, the Inverter Section will NOT be activated, and the AC side loads will lose
AC power. EVO will operate in Standby Mode as long as AC input power is NOT available.
• Operating Mode Screens for Standby Mode will be displayed
(See 7 scrollable Screens under Column 2 – “GROUP
