• Power Transformer: In case the temperature is >130oC, the BULK CURRENT setting is automatically reduced by
0.2% every 20 sec
• Heat Sink: In case the temperature is >90oC, the BULK CURRENT is automatically reduced by 0.2% every 20 sec
4.10 OPTIONAL REMOTE CONTROL EVO-RC FOR PROGRAMMING OF MODES OF OPERATION
AND PARAMETERS
Optional Remote Control Model EVO-RC-PLUS [Fig 2.4(a)] will be required for more advanced control and monitoring.
Please see separate Owner's Manual for EVO-RC-PLUS. The Remote Control comes with 10M / 33 ft., RJ-45 Data Cable.
The Remote plugs into RJ-45 Jack on the front panel of the unit (7, Fig 2.1). It has provision for Data Logging using SD
Card of up to 16 GB (FAT16 / FAT32). It also has its own Real Time Clock and Super Capacitor Type of Internal Battery.
The Remote Control will be required for Firmware upgrade through the SD Card.
Detailed messaging is available through its LCD display and LEDs. This remote will also be required for programming
of various parameters to suit specific requirements. Each programmable parameter has a Default Value. This unit
has been shipped with the various parameters set at the Default Values. Programmable and Default values
are shown in Tables 6.2 to 6.6.

For background information on batteries and charging process, please read Section 1.4, "General
Information - Battery Related". All battery charging voltages are specified at battery temperature
of 25˚C / 77˚F.
5.1.1 General Information
EVO Series is a Low Frequency Type, Pure Sine Wave, Single Phase Inverter-Charger with a built-in Transfer Relay. It
uses high performance, 100MHz SP (Digital Signal Processing) type of micro-controller and Pulse Width Modulation
(PWM) control. It is Bi-Directional i.e. it uses a common Converter Section consisting of Low Frequency Isolation
Transformer and Mosfet based H-Bridge that can work in two directions as follows:
1) AC to DC Charging Mode: The common Converter Section is used to convert external AC input power to
DC output power to charge the batteries and at the same time, pass through the AC input power to the AC
loads
2) DC to AC Inverting Mode: The common Converter Section is used to convert DC input power from the
batteries to AC output power to feed the AC loads
