ML4860N15 — Model details
Description
Choose an SRNE ML Series MPPT controller for a 12V, 24V, 36V or 48V off-grid battery system. The built-in LCD makes operating information and charging settings accessible without a separate display, while passive cooling supports quiet operation.
- ML4830N15: up to 30A charging, with a separately rated 20A load output.
- ML4860N15: up to 60A charging, also with a 20A load output.
- Configurable charging for supported lead-acid and lithium batteries.
- RS232 and RS485 communication; BT-1 Bluetooth monitoring requires an optional module.
- IP32 enclosure for protected installations; follow the manual ventilation and mounting requirements.
Choose the model for your battery voltage and array size. PV power ratings depend on battery voltage. Manufacturer documents differ on the PV voltage ceiling; confirm the applicable hardware revision and cold-weather array voltage before installation.
