INFO
The following programmable parameters have been referred to in the description be-
low. Links to detailed information on these parameters are given below:
• “LOW VOLT ALARM”: Please refer to Section 4.4.2.8
• “GS DETECT TIME”: Please refer to Section 4.4.2.16
• “EQUALIZE-4STAGES”: Please refer to Section 4.4.2.12
• “GEN ON TIME”: Please refer to Section 4.4.2.17
• “GEN OFF TIME”: Please refer to Section 4.4.2.18
• “RESET VOLTAGE”: Please refer to Section 4.4.2.7
The Normally Open “NO” and “Common” contacts of Status Relay (14, Fig 2.1 in the Owner's
Manual for Evolution
TM
Series Inverter/Charger Models EVO-2212 / 3012 / 2224 / 4024) can be
used to also automatically start and stop generator through appropriate external Generator
Auto Start / Stop Module. 3 options (Options 2, 3 and 4) explained below are available for
carrying out this function depending upon user requirements. The “Common” and “NO”
terminals are wired to the optional Generator Auto Start / Stop Control Module which, in turn,
is wired to the Remote Start / Stop connections on the Generator. The AC output terminals
of the Generator are wired to the Generator Input Terminals on the EVO
TM
(7, 8, 9 in Fig 2.3 in
Owner's Manual for EVO
TM
Series Inverter/Charger Models EVO-2212 / 3012 / 2224 / 4024).
For installation details, please refer to Section 3.15 / Fig 3.13 and Section 3.16 / Fig 3.14 in the
Owner's Manual for EVO
TM
Series Inverter/Charger Models EVO-2212 / 3012 / 2224 / 4024.

INFO
It is recommended that “GSCM-Mini” Series of Generator Start / Stop Control Module,
appropriate for the generator to be used, may ordered directly from
Atkinson Electronics www.atkinsonelectronics.com
Based on the Generator Start Logic contained in of one of the selected Options 2, 3 or
4 explained below, the Status Relay will be switched ON (energized), its “Common” and
“NO” contacts will close and the external Generator Start / Stop Control Module will initiate
automatic starting of the Generator. Once the Generator has started and starts feeding AC
output to EVO
TM
(within the programmed limits of voltage and frequency), the EVO
TM
will be
synchronized with the Generator and once synchronization is completed, the load will be
transferred instantly (within 1 ms) to the Generator at Zero Crossing of the voltage waveform
for seamless transfer and for better protection of Transfer Relay contacts. The EVO
TM
will now
operate in “Charging Mode” with the AC power from the Generator charging the batteries as
well as providing power to the AC load(s).
Based on the Generator Stop Logic contained in one of the selected Options 2, 3 or 4 explained
below, the Status Relay will be switched OFF (de-energized), its “Common” and “NO” contacts
will open and the external Generator Auto Start Control Control Module will initiate automatic
stopping of the Generator. When AC output of the generator is shut down, the EVO
TM
will
automatically transfer the AC load(s) to the “Inverter Section” within 16 ms.
