Key Features
Key Features
- 50A DC-DC vehicle charging with automatic buck-boost regulation across a 9–46V input range
- Adaptive MPPT solar charging up to 46V input, with ARK's self-tuning algorithm for low-light and shading conditions
- AC-DC charging (23A) via an ARK-approved 24V adapter, sharing the solar input port
- Vehicle Sense Technology (VST) — detects engine operation automatically, no ignition wire required
- 500A integrated busbar and smart shunt — battery monitoring and load distribution built into the negative/positive path, no external shunt or busbar needed
- 3 integrated MEGA fuse slots for protected load outputs, field-serviceable
- Lithium recovery mode — safely wakes batteries shut down by BMS protection
- Onboard display + built-in Wi-Fi — live monitoring from the unit or from any phone/tablet/laptop, no app required
- 4-step thermal derating and multi-sensor protection for sustained high-current operation in hot environments
- Supports Lithium, AGM, GEL, Flooded, and Calcium battery chemistries, 60–600Ah

Intended Use
Intended Use
The DMC50 is designed for 12V auxiliary battery systems in automotive, caravan, marine, and off-grid applications, for use in the United States, Australia, and Canada. It is not intended for grid-connected or utility-interactive systems, life-support or safety-critical applications, or battery systems above 12V nominal. Installation should be performed by a qualified installer or a technically competent user familiar with high-current DC systems.
One enclosure, not five boxes
Traditional 12V setups wire together a separate MPPT charger, AC-DC charger, DC-DC charger, busbar, smart shunt, comms network and display. The DMC50 combines all of this into one unit with a single set of input and output connections.
What's Inside
Every function below is part of the same enclosure and the same firmware.
50A DC-DC Charging
Buck-boost charging from a vehicle alternator, 9–46V input range, automatic buck/boost switching.
Adaptive MPPT Solar
Self-tuning solar charging up to 46V input, designed to hold output steady in low light and partial shade.
AC-DC Charging
23A charging from an ARK-approved 24V adaptor, sharing the solar input port.
Vehicle Sense Technology
Detects engine operation automatically — no ignition wire to run.
500A Busbar & Smart Shunt
Battery negative routes through an integrated shunt; no external monitor or busbar block needed.
3x MEGA Fuse Slots
Field-serviceable fuse protection for load circuits, built into the main power block.
Lithium Recovery Mode
Limited, time-boxed recovery charge (7A, 2 min max) for batteries shut down by BMS protection.
Onboard Display + Wi-Fi
Local display plus a built-in Wi-Fi captive portal — monitor from a phone, tablet or laptop, no app required.
4-Step Thermal Derating
Output steps down automatically above 80°C and recovers once temperature drops, instead of cutting out.
