EG4 Chargeverter GC – 48V 100A Battery Charger – 240/120V Input

Description

The EG4 Chargeverter represents a specialized solution for direct battery charging in off-grid and backup power systems. 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.

Generator Compatibility & Power Conditioning

Traditional off-grid systems face significant challenges when generators connect through inverters. Most whole-house 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 3000W to industrial units.

The unit specifically addresses “dirty power” from budget generators with high Total Harmonic Distortion (THD). 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.

Charging Performance & Control

The Chargeverter operates at approximately 90% efficiency, delivering up to 5120W of charging power from a 240VAC input. The adjustable charge current ranges from 0-100A at 240VAC, with charge voltage adjustable from 43-57VDC (defaulting to 54VDC for optimal LiFePO4 charging). The unit automatically adjusts capacity at 120VAC input while maintaining stable operation across the entire 90-264VAC input range.

The charging profile provides bulk charging for lithium iron phosphate batteries, reaching 3.56V per cell at maximum voltage. This ensures 95% or greater state of charge without risking cell imbalance, while maintaining consistent parameters regardless of input fluctuations common with generator power.

Applications

The Chargeverter connects directly to battery bank bus bars using standard 5/16″ terminal lugs, with included 6ft cables accommodating most installations. Primary applications include weather resilience for solar systems during extended cloudy periods and backup charging during grid outages. 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.

For connecting the Chargeverter to a 120V source, a quick-connector facilitates an easy change-over to the NEMA 5-15P input power cord that plugs into a standard household receptacle.
