Product Details
Product Overview
The MPPT Solar Charge Controller Series (30A/40A/50A/60A) utilizes advanced Maximum Power Point Tracking (MPPT) technology to optimize solar panel output, increasing energy conversion efficiency by up to 30%. Supporting a wide 12V–96V system voltage and compatible with multiple battery types (lead-acid, gel, Li-ion, LiFePO4, etc.), it is the ideal solution for home energy storage, off-grid systems, and commercial/industrial applications.
