SN Series MPPT solar charge controller

Silent, sealed MPPT controllers for 12V to 48V vehicle systems, with Bluetooth, a starter-battery output and a year of charge history.

Part of the LIBERGRID system

The SN Series is LIBERGRID’s solar charge controller. Paired with a DN Series DC-DC charger, it is the alternative to the all-in-one DDN, and suits systems with more solar or a battery voltage up to 48V.

Models

SN100-30	30A, 12V or 24V
SN100-60	60A, 12V or 24V
SN150-35	35A, 12V to 48V

Features

Continuous maximum power point tracking gets the most from the panels.
SN100 models can trickle-charge a 12V starter battery.
Bluetooth app monitoring and firmware updates, with 365 days of charge records.
Sealed and fanless, so it’s silent.
