Smart MPPT Solar Charge Controller — 40A, 12/24V Auto
Overview
This compact MPPT solar charge controller extracts maximum power from your panels, adapts automatically between 12V and 24V systems, and protects your battery with targeted charge profiles. It’s designed for reliable, efficient charging in small off-grid systems and backup setups.
Benefits
- Get more usable energy from the same panels — high MPPT tracking pulls more power under changing sunlight.
- Extend battery life by using charge profiles matched to your battery chemistry (lead?acid and lithium options).
- Reduce maintenance and worry with built?in protections against reverse discharge and overvoltage.
- Save space and simplify installation thanks to a compact, lightweight design and common negative connection.
- Keep performance history for troubleshooting and optimization with onboard charging data storage.
Features
- MPPT (Maximum Power Point Tracking) charging technology
- Tracking efficiency above >99.5%
- Charge conversion efficiency up to ≤98%
- Automatic 12V / 24V detection and adaptation
- Reverse discharge protection and overvoltage protection
- Common negative connection for easier wiring
- Selectable battery type presets for lead?acid (Gel, AGM, WET, Crystal, Calcium) and lithium (LCO, LFP, LTO)
- Onboard charging data storage for monitoring and diagnostics
- Conformal coating on internal PCB for improved durability
- Extensive internal electronics with in?circuit and safety protections
- Designed and manufactured in?house
