About this item

• 1. [DUAL PV INPUT & 100A MASSIVE CAPACITY] What makes this 100A MPPT charge controller stand out? It features a rare DUAL PV INPUT design (50A x 2) for maximum solar utilization. Supporting up to 250V Max PV open-circuit voltage and a massive 5200W input (at 48V), it is the ultimate powerhouse for heavy-duty RVs, cabins, and off-grid solar systems.
• 2. [INNOVATIVE NO-BATTERY MODE] Can I run a solar system without batteries? Yes! The TEP10425 supports an advanced battery-less operation mode. When there is sufficient sunlight, it can directly supply power to your inverter and loads. It works flawlessly with 12V, 24V, and 48V systems, supporting AGM, GEL, Flooded, and Lithium (LFP/NCM) batteries.
• 3. [99.5% MPPT EFFICIENCY & SMART BMS] Stop wasting solar energy. Our advanced MPPT algorithm guarantees a tracking efficiency of $ge99.5%$ and a peak conversion rate of 98.4%. It features a built-in independent BMS communication port, ensuring highly reliable charge/discharge management for lithium batteries across different brands.
• 4. [UP TO 6-UNIT PARALLEL EXPANSION] Need to expand your off-grid system later? The built-in CAN communication port allows up to 6 controllers to work in parallel. This makes capacity expansion incredibly easy, whether you are scaling up a marine solar setup or an industrial monitoring power system.
• 5. [RUGGED DUSTPROOF & SAFE DESIGN] Built for harsh environments, the isolated two-compartment airflow design separates electronic components from the cooling system, ensuring superior heat dissipation and dust resistance. It automatically reduces charging power if the internal temperature exceeds $81^{ rc}C$ and includes comprehensive protections against PV reverse polarity and short circuits.
