EG4 Chargeverter Plus - High Performance Battery Charger for 48V Energy Storage Systems
The EG4 Chargeverter Plus is a robust, high performance battery charger designed to charge batteries in a 48V alternative energy storage system. With a maximum output of 5.12kW at 240Vac and an ingress protection rating of IP54, this efficient power supply is suited for sheltered outdoor use and delivers reliable performance for on-grid and off-grid systems.
Optimized Power for Diverse Setups
This battery charger has an AC input voltage range of 90-264Vac, making it compatible with 120Vac, 208Vac, or 240Vac power supplies. The system automatically adjusts to provide optimal performance, outputting up to 5.12kW at 240Vac, 2.56kW at 120Vac, or 4.1kW at 208Vac. This gives a max charge current of 100A, 50A, or 80A respectively.
The adjustable charge voltage ranges from 40-60Vdc with a default setting of 57Vdc, and the adjustable charge current provides precise control based on your system's specific needs.
Handles Dirty Power and Unreliable Sine Waves
Designed specifically for generator use, the EG4 Chargeverter Plus excels where other chargers struggle. Lower budget generators can produce dirty power that fluctuates in voltage or frequency and creates unreliable sine waves. This power can damage sensitive electronics, but it's possible for the Chargeverter Plus to plug directly into a generator and clean the power before passing it to other devices.
Since this Chargeverter pairs well with a generator, it's perfect for adding bad weather resilience to an off-grid system with unpredictable weather patterns. Protection against power outages starts with the EG4 Chargeverter Plus.
Advanced Communication and Control
The built-in RS485 communication port enables closed loop communication between the charger and properly equipped batteries, including connected EG4 batteries. This facilitates real-time data transmission, including battery state of charge data.
When operating without closed loop communication, the charger uses nominal battery voltage to control charging, maintaining proper functioning.
Automatic Generator Start Function
Connect your generator's automatic start circuit to the Chargeverter Plus dry contacts for added generator control. The Chargeverter can automatically start and stop your generator based on user defined voltage thresholds or SOC levels, saving time and fuel while ensuring your batteries maintain optimal charge. The adjustable preheat time (0-5 minutes) and cooling time (0-5 minutes) extend the generator’s longevity and maintain optimal performance.
Easy Installation and User-Friendly Design
The compact design measures just 4.3×16.1×7.1in and weighs only 13.67lbs, and the included mounting brackets and cables create a straightforward installation. The built-in LCD interface displays voltage, charging amperage, battery state of charge, power temperature, and more. The controls are easy to navigate and enable quick parameter adjustments without complicated setup procedures.
Durability and Safety Features
Built for reliability in challenging conditions, the IP54 rated enclosure guards against dust ingress and splashing water. The Chargeverter is suitable for sheltered outdoor installations in non-condensing humidity up to 95%. The operating temperature range of -40°F to 131°F makes it usable in both hot and cold climates. Multiple protection features include a built-in breaker for quick shutoff, output ripple less than 500mV, and comprehensive safety guards against power issues.
Versatility for Various Applications
The EG4 Chargeverter excels when powering residential systems, commercial installations, RV setups, or backup power systems. It's compatible with 15s or 16s cell lithium batteries, so it works with 48V batteries from many manufacturers. The system's efficiency and high performance make it ideal for both grid-tied and off-grid energy storage systems.
