Installation Guide
1. Securely mount the DCDC-40A close to the auxiliary battery to minimize voltage drop. 2. Connect the input (Alternator) and output (Battery) using appropriate gauge cable (6AWG recommended). 3. For Smart Alternator vehicles, connect the ignition signal wire to a switched 12V source. 4. Set the battery chemistry mode using the selection button on the faceplate.
Questions & Answers
Is this a genuine original part?
This is a premium Solarika-branded replacement part, manufactured to meet or exceed original equipment (OE) standards for off-grid power management.
How do I know if it is compatible?
If you require a 40A charge rate for a 12V dual battery system and have a solar input requirement, this DCDC-40A unit is a universal fit for almost all 12V/24V vehicle architectures.
Can I use this with unregulated solar panels?
Yes. This unit features a built-in MPPT regulator. You must connect unregulated solar panels directly to the solar input; do not use a separate solar controller between the panel and this charger.
Note: Please verify your system's amperage requirements and battery chemistry compatibility before installation. Professional electrical installation is recommended for optimal safety.
