EG4 | Chargeverter Plus

Overview

When solar production drops, a generator can keep the battery bank topped up. The EG4 Chargeverter Plus is an AC-to-DC charger that sits between the generator and a 48V lithium bank, regulating incoming power.

Key benefits

• Handles unstable or 'dirty' power from lower-budget generators, helping prevent charging errors and inverter faults.
• Works on 120VAC, 208VAC, or 240VAC, with best output on 240VAC.
• Dry contacts support automatic generator start and stop based on voltage or state of charge.
• Programmable warm-up and cool-down give smoother generator starts and shutdowns.

Key features

• 100A maximum continuous charging at 240V; 50A at 120V
• CAN and RS485 ports for SOC-based charging with compatible lithium batteries
• Integrated breaker for fast output shutdown
• UL Listed, IP54-rated
• Supports 40-60V battery systems
• Maximum altitude 9,843 ft (3,000 m)

Ideal use

For homes, cabins, and shops with solar and a generator that need a reliable backup charging path during storms, outages, or short winter days.

What is included

• Power supply cord
• Dry contact cable
• Positive (red) and negative (black) 4 AWG battery cables
• CAN/RS485 communication cable (RJ45 to RJ45)

From the manufacturer

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.
