Specifications
Product Description
The MPPT Controller TBB Power SP250-100 250 V 100 A 48 V is a professional high-current solar controller, specifically designed for 48 V battery banks. With a wide MPPT tracking range of 65–245 V, it supports up to 7.5 kW of connected photovoltaic power and delivers up to 5.88 kW of charging power to batteries, maintaining a maximum efficiency of 98% and MPPT efficiency ≥ 99.9%. It incorporates 365-day data logging, RS485 communication, and forced ventilation, ensuring thermal stability and continuous operation in demanding climates.
Main Features
- High charging current: 100 A at 48 V for rapid replenishment.
- High PV voltage: 250 V Voc with MPPT range 65–245 V for long strings and reduced wiring losses.
- Admissible PV power: 7.5 kW (input) and up to 5.88 kW charging power at 48 V.
- Efficiency: up to 98% @48 V; MPPT tracking efficiency ≥ 99.9%.
- RS485, dry contact (30 Vdc/2 A), and 365-day datalogger (daily/monthly/total) with real-time records.
- Forced ventilation, LED+LCD display, IP21, and terminals up to 35 mm².
Advantages or Benefits
- More production and less loss: operating at 250 V reduces cable cross-section and voltage drop, maximizing PV field performance.
- Accelerated recharge of 48 V banks thanks to continuous 100 A and TBB II multi-stage algorithm.
- Battery protection: precise absorption/float voltages, programmable equalization (lead-acid), and compatibility with lithium (LiFePO₄) with BMS.
- Control and traceability with RS485, dry contact for alarms/automation, and 365-day historical logging.
- Thermal reliability due to forced ventilation and temperature management for continuous service.
Purpose or Applications
Recommended for medium and high-power off-grid solar systems at 48 V: high-consumption homes, businesses, workshops, telecommunications, remote stations, and backup solutions where high charging current and long photovoltaic strings are required.
