Victron Energy SmartSolar MPPT 100/20 48V
Victron Energy SmartSolar MPPT Solar Charge Controller 100V, 20A, 48V | Bluetooth Charge Controllers for Solar Panels
Victron's 20 A SmartSolar model adds 48V support to the usual 12/24V, with automatic detection, built-in Bluetooth, a VE.Direct port and a 100 V PV input. It handles 290 W at 12V, 580 W at 24V or 1160 W at 48V, and has an IP43 rating with a -30 to 60 ℃ operating range. It is one of the few low-current controllers that also works with 48V banks, suiting app-monitored van and cabin systems.
