Features MPPT solar input, multi-battery type selectable charging, a battery wake-up feature, LED indicator, smart alternator compatibility, IP68 rating, and solar/alternator priority selection. Vehicle input voltage: 11.5-32V. Solar input voltage: 9-32V. Recommended battery capacity: 120-400Ah. Australian certified. 2-year warranty.
The Invicta SNLC12V40DC is the 40A variant in the Invicta DC to DC charger range, purpose-built to match the Invicta charge profile for LiFePO4 lithium batteries as well as SLA, AGM, Calcium, and Na-ion battery chemistries. The selectable battery type allows the correct charge voltage to be set for the connected battery. A battery wake-up feature allows the charger to initialise and charge deeply discharged batteries. Smart alternator compatibility ensures correct charging operation in vehicles fitted with variable-output smart alternators.
The MPPT solar input accepts 9-32V solar panel input for combined alternator and solar charging in a single unit, with solar and alternator input priority selectable. The IP68 rating and confirmed underbonnet installation capability make the SNLC12V40DC suited to demanding installation environments. An ignition cable is included for ignition-controlled charging operation. The unit measures 116mm (L) x 164mm (W) x 42mm (H). Australian certified, backed by a 2-year warranty.
40A maximum charging current: Provides up to 40A of charging current for battery capacities of 120-400Ah, suited to larger auxiliary battery installations in 4WD, caravan, and marine applications.
Multi-battery type selectable: Battery type is selectable to match the charge voltage profile of the connected battery, covering SLA, AGM, Calcium, LiFePO4, and Na-ion chemistries in a single unit.
MPPT solar input 9-32V: Integrated MPPT solar input accepts 9-32V from a solar panel for combined alternator and solar charging, with solar and alternator input priority selection.
