Solarika 40A DC to DC Charger (SKU: DCDC-40A)

Intelligent Dual Battery Charging System with MPPT Solar Regulator

The Solarika DCDC-40A is a state-of-the-art 40 Amp DC to DC battery charger engineered to maintain your auxiliary battery at peak performance. Designed for the rugged demands of off-road touring, it efficiently charges from both your vehicle's alternator while driving and from solar panels when stationary. Its multi-stage charging algorithm ensures a 100% charge for various battery chemistries, extending their lifespan and reliability.

RELIABILITY: Built with a heavy-duty, vibration-resistant casing and IP66/IP67 rated protection to withstand the harshest engine bay or chassis environments.

Key Features

  • Dual Input: Charges from alternator and solar.
  • Smart Alternator Ready: Senses ignition for modern vehicles.
  • Integrated MPPT: Maximize solar efficiency by up to 30%.
  • Multi-Chemistry: Supports Lithium (LiFePO4), AGM, Gel, & Lead Acid.
  • Advanced Safety: Over-temp and reverse polarity protection.

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.
