Page 7: Brief Introduction
4. BRIEF INTRODUCTION This manual describes the installation and operation of the EG4 Chargeverter-GC. Please read this manual carefully before installation and operation. CHARGEVERTER-GC OVERVIEW The EG4 Chargeverter-GC is a robust AC-to-DC converter designed specifically for 48 VDC Lithium battery charging in on-grid and off-grid Energy Storage Systems. The charger can operate on 120, 208, or 240VAC and is capable of up to 100 Amps of DC charging current. -

6.2.2 LCD PARAMETER SETTINGS The following table provides detailed instructions for modifying Chargeverter-GC parameter settings using the LCD interface. NOTE: When configuring the Chargeverter to charge by voltage, ensure the SOC STOP is set before setting SOC START or the Chargeverter will default the SOC START setting to its original value. - Page 15 Press the “DOWN” button to highlight the next digit of the voltage (see screen to the right). Press the “UP” button to make changes to this digit (Do not use the “DOWN” button). Press “ENTER” to accept the changes or “ESC” to ignore them.
- Page 16 Press the “DOWN” button to highlight the BATT START setting and repeat the steps above to make and save changes to the BATT START parameter. Repeat the steps above to make and save changes to the CURRENT, SOC STOP, and BATT STOP parameters, as needed.

Page 17: Charger Communications
6.3 CHARGER COMMUNICATIONS The Chargeverter-GC includes the option to connect the charger to a properly equipped battery for communications over RS485. The charger will ping the battery to get the SOC/Voltage status and use that information to start and stop generator charging at the preset thresholds. These thresholds are adjustable via the SETTINGS display. -
Page 18: Dry Contact Description
6.4 DRY CONTACT DESCRIPTION There are dry contacts available from the RJ11 jack on the right side of the charger to control a generator. The RJ11 jack has 6 pins used in pairs to provide a Normally Open (NO) signal, a Common (C), and a Normally Closed (NC) signal. -
Page 19: Working With A Generator
6.5 WORKING WITH A GENERATOR The Chargeverter-GC dry contacts are specifically designed to interface with a generator. The charger AC input is simply plugged into the generator 240 VAC output and the dry contacts are used to start/stop the generator based on user defined thresholds of battery SOC or voltage. During this mode of operation, the charger is powered from the battery’s DC voltage. - Page 20 The following table shows the Generator ON/OFF status based on the user defined thresholds and the Normally Open (NO) dry contacts on the Chargeverter-GC. SOC is used if charger/battery communications are being used. Voltage is used if SOC is not available.
