LensunSolar 20A 12V DC to DC Dual Battery MPPT Charger Controller
What is a DC to DC charger?
The DC-DC charger connects between the starter and the leisure battery, or between the solar panel and the leisure battery. It charges the leisure battery by drawing power from either the vehicle’s alternator or the solar panel.
This LensunSolar DC to DC charger offers cutting-edge technology and efficiency in solar and battery charging, making it easy to use. It combines a solar charge controller and charger in one, with inputs for both generator start batteries and solar panels. Plus, it’s versatile—compatible with AGM/GEL, lead acid, lithium, and calcium batteries
Feature:
Multi-Input Efficient Charging: The LensunSolar DC-DC charger combines a solar charge controller and charger in one unit. With inputs for both the generator start battery and solar panel, it can efficiently charge various battery types, including AGM/GEL, lead acid, lithium, and calcium batteries.
Intelligent MPPT Charging: This DC-DC charger uses advanced Maximum Power Point Tracking (MPPT) technology to maximize solar energy capture, with up to 99% efficiency. The system also records charging patterns for smarter, more efficient use.
One-Way Charging: This technology enhances safety by isolating the charging of primary and secondary batteries. It also prevents reverse charging and power loss from the house battery.
Comprehensive Protection: Includes low-voltage protection, overcharging, and short-circuit safeguards for extended battery life.
User-Friendly: Clearly labeled wiring and indicator lights make setup easy and ensure proper connections.
Specifications:
Input DC Battery: 12.5-16V
Input Solar Panel: 16-25V
Output: 14.4-15.4V (Stop charging when alternator output or vehicle battery below 12.5V)
Output Current: DC output 20A/40A, Solar output 20A/40A
Minimum Start Voltage: 2 Volts - For battery being charged
Bulk Charge Voltage: 14.7V (AGM/Gel), 14.4V (Lead Acid), 15.4V (Calcium), 14.4V (LifePO4)
Absorption: Constant voltage with automatic amperage control
Folat Charge Voltage: 13.5V (AGM/Gel), 13.5V (Lead Acid), 13.5V (Calcium)
Float Charge Current: 0-20A, 0-40A
Perfect for a Wide Range of Applications:
- Run appliances while camping
- Power 12V fridges, lights, or other devices
- Ideal for solar panel charging
- Great for 4x4 and marine use
- Heavy-duty aluminum case with mounting brackets
In short, DC-DC chargers are smart chargers that use your vehicle’s alternator to create the optimal output for charging auxiliary batteries. Since alternators aren’t designed to charge both the main and auxiliary batteries efficiently, DC-DC chargers solve this issue, extending battery life and performance.
Packing:
1 x LensunSolar 20A or 40A 12V DC to DC Charger
