Description
The EG4 Chargeverter Plus is a robust AC-to-DC converter designed specifically for 48VDC lithium battery charging in on-grid and off-grid energy storage systems, with IP54-rated outdoor installation capability and full generator compatibility.
Key Features
- 120V / 208V / 240VAC Input Capability — Operates on all three common AC input voltages, optimized for 240VAC for maximum 100A / 5120W output, with 120VAC and 208VAC supported via optional adapter plug.
- RS485 Closed-Loop Communication — RJ45 CAN/RS485 port enables direct communication between the charger and battery for SOC-based user-defined charging thresholds, with voltage-based fallback when SOC data is unavailable.
- Optimized for Generator Use — Tolerates generator "dirty power" without issue, and supports automatic generator start/stop via dry contact interface at preset voltage or SOC thresholds.
- Built-In Breaker with IP54 Outdoor Rating — Integrated output breaker provides rapid shutdown for safety, while IP54 ingress protection guards against dust and splashing water for outdoor installation.
- Fully Adjustable Charge Current and Voltage — Charge current adjustable from 0–100A (240VAC) and charge voltage adjustable from 40–60VDC, providing precise control for 15s or 16s cell lithium battery banks.
The Chargeverter Plus delivers up to 5120W of charging power at 240VAC input, making it one of the highest-output single-unit 48V lithium chargers available for residential and commercial off-grid energy storage applications.
With a wide operating temperature range of -40° to 131°F and compatibility with both 50Hz and 60Hz AC sources, the Chargeverter Plus is suited for diverse off-grid and backup power installations worldwide.
The unit ships with UL1012 and FCC Class B certifications and carries a 3-year warranty when used indoors, making it a reliable long-term component in any 48V lithium battery system.
