The EG4 Chargeverter Plus (model CU-48-5000-OD-01) is a rugged AC-to-DC battery charger for 48V lithium systems. It sits between a generator and your battery bank, regulating incoming power so you can charge from a generator safely when solar production drops. Because it tolerates the "dirty" power that budget generators produce, it avoids the charging errors and inverter faults that power can cause. It strengthens a solar system with a reliable backup charging path during storms, outages and short winter days.
Highlights
- Up to 100A DC charging on 240VAC (80A on 208VAC, 50A on 120VAC)
- Wide AC input: 90–264 VAC, optimized for 240VAC
- Closed-loop communication: CAN / RS485 for state-of-charge-based charging thresholds; uses battery voltage when no communication is present
- Auto generator start: dry contacts (NO/NC/C) with two-wire start and programmable warm-up and cool-down
- Wide battery support: 40–60V, 15s or 16s lithium
- Built-in breaker for quick output shutoff
- IP54 rated for outdoor installation; UL 1012 listed
In the box
- Power supply cord
- Dry contact cable
- Red and black 4 AWG battery cables
- CAN/RS485 communication cable (RJ45 to RJ45)
