EG4 Electronics Chargeverter-GC 48V 100A Battery Charger for LiFePO4 Batteries, 240V or 120V Input with AGS and Built-in Breaker

Overview

Bypassing the inverter entirely, the EG4 Chargeverter-GC converts AC from a generator or grid connection straight into DC for a 48V LiFePO4 bank. It delivers up to 100A of charging current and includes AGS and a built-in breaker.

Key benefits

• Avoids the generator overload and voltage collapse that can occur when generators feed large inverters.
• Accepts generator power with THD above 5%, including construction-grade and older diesel units.
• Isolates generator power from household circuits to protect sensitive electronics.
• Works with generators from 3kW upward.

Key features

• 90% efficiency
• Up to 5.12kW charging power from 240Vac
• Adjustable charge current 0-100A at 240Vac; charge voltage 43-57Vdc
• Stable operation from 90 to 260Vac input
• Connects to battery bus bars with standard 5/16 in terminal lugs
• Quick-connector for household outlet connection

Ideal use

For solar systems facing extended cloudy periods, backup charging during grid outages, and remote sites where generator quality varies.

From the manufacturer

Specialized Charging for Off-Grid and Backup Power: This 48V battery charger converts AC power from generators or grid connections directly into DC power for battery banks, bypassing the inverter entirely. By eliminating the inverter from the charging path, the Chargeverter solves critical issues that plague traditional generator-to-inverter configurations. Simple Connections for Weather Resilience: The Chargeverter connects directly to battery bank bus bars using standard 5/16″ terminal lugs, and the included 6ft cables accommodate most installations. Primary applications include weather resilience for solar systems during extended cloudy periods and backup charging during grid outages. Off-Grid Energy Solutions: The unit excels in remote locations where generator quality cannot be guaranteed or where existing diesel generators must integrate with modern battery systems. By isolating generator power from household circuits, the Chargeverter protects sensitive electronics while maximizing generator fuel efficiency through optimized loading. Charging Performance & Control 90% efficiency Up to 5.12kW charging power from 240Vac Adjustable charge current from 0 to 100A at 240Vac Adjustable charge voltage from 43 to 57Vdc Maintains stable operation from 90 to 260Vac power input Maintains a consistent charge regardless of generator power fluctuations Quick-connector facilitates connection to household outlet Provides Consistent Generator Power Traditional off-grid systems face significant challenges when generators connect through inverters. Most whole-home systems utilize 12kW or larger inverters that disengage their charging modules to pass generator power through to loads, often resulting in generator overload, voltage collapse, and potential inverter failure not covered under warranty. The Chargeverter eliminates these risks by accepting AC input directly from generators ranging from 3kW to larger industrial units. The unit specifically addresses “dirty power” from budget generators with high THD (Total Harmonic Distortion). While inverters typically reject generator input with THD exceeding 5%, the Chargeverter accepts and conditions this power for safe battery charging. This compatibility extends to construction-grade units, older diesel generators, and other sources previously incompatible with sensitive inverter electronics. Beyond applications that need conditioning, the 100A output of the Chargeverter is highly capable of restoring the capacity of large LiFePO4 batteries quicker than chargers far beyond this pricepoint. Choose the EG4 Chargeverter for reliable power that’s safe for sensitive devices. The EG4 Chargeverter-GC is a 48V battery charger that delivers up to 100A of charging current directly to LiFePO4 battery banks. This charger converts AC power from generators or grid connections into DC power, bypassing the inverter to avoid compatibility issues with inconsistent sine wave output.
