When Solar Stops, EG4 Chargeverter Plus Keeps You Powered

The EG4 Chargeverter Plus is a powerful AC-to-DC battery charger designed to make generator charging simple, safe, and reliable when solar production drops. It sits between your generator and battery bank to regulate incoming power, protect your equipment, and keep stored energy available when you need it most. Rather than replacing solar, the Chargeverter Plus strengthens your system by providing a dependable backup charging path during bad weather, outages, or low-production seasons.

Key Benefits

• Smart Generator Backup for Solar Systems: Allows you to safely charge 48V lithium batteries with a generator when solar output is reduced due to clouds, storms, or short winter days.
• Works with Lower-Budget Generators: Designed to handle unstable or “dirty” generator power, helping prevent charging errors, inverter faults, and system shutdowns.
• Wide AC Input Compatibility: Operates on 120VAC, 208VAC, or 240VAC, with optimized performance on 240VAC for maximum output.
• Closed-Loop Battery Communication: CAN and RS485 communication ports allow SOC-based charging when paired with compatible lithium batteries.
• Automatic Generator Start Ready: Built-in dry contacts support automatic generator start and stop based on voltage or state-of-charge thresholds.
• Built-In Safety Protection: Integrated breaker allows fast output shutdown for added safety and system protection.

Use Cases

Ideal for residential and off-grid energy storage systems that rely on solar but need a dependable backup charging option. Perfect for homes, cabins, shops, and backup power systems where a generator is used to maintain battery charge during low solar production or extended outages.
