Product Summary:

The Chargeverter Plus (EG4CV48V100AIP54) is a UL certified AC to DC converter delivering a stable, 48V DC power output up to 5 kW. Paired with an EG4 ESS, the solution enables seamless integration of high THD power sources, such as small generators or dirty grid power, delivering power conditioning and UPS functionality.
Key Features:
  • UL Certified Power Conversion: Delivers safe, reliable AC-to-DC charging with a stable 48V DC output up to 5 kW.
  • High-THD Source Compatibility: Conditions “dirty” generator or unstable grid power for smoother charging and improved performance.
  • Outdoor-Ready Protection (IP54 Rated): Supports covered outdoor installations with enhanced protection against dust and water exposure.
  • Extreme Temperature Operation: Built to perform in harsh environments from -40°F to 131°F.
  • Generator Two-Wire Start + Programmable Warm Up/Cool Down: Enables automated generator control and smarter run cycles for improved efficiency and reliability.

EG4 Chargeverter Plus: Backup Power You Can Rely On

When solar production slows, the EG4 Chargeverter Plus keeps your batteries charged and your system running. This powerful AC-to-DC battery charger sits between your generator and battery bank to regulate incoming power, protect equipment, and provide reliable stored energy during bad weather, outages, or low-production seasons. It doesn’t replace solar, it strengthens your system with a dependable backup charging path perfect for residential, off-grid, and backup energy storage systems needing dependable generator charging during low solar production or extended outages. Great for homes, cabins, shops, and workshops.


Key Benefits

  • Generator Backup for Solar Systems: Safely charge 48V lithium batteries with a generator when solar output is reduced by clouds, storms, or short winter days.
  • Works with Budget Generators: Handles unstable or “dirty” generator power to help prevent charging errors, inverter faults, and shutdowns.
  • Wide AC Input Support: Operates on 120VAC, 208VAC, or 240VAC, with best performance at 240VAC.
  • Closed-Loop Communication: CAN and RS485 ports enable SOC-based charging with compatible lithium batteries.
  • Automatic Generator Start Ready: Built-in dry contacts support auto start/stop based on voltage or state-of-charge thresholds.
  • Built-In Safety Protection: Integrated breaker allows fast output shutdown for added protection.
