The SL-W and SL-R series are advanced lithium battery types designed specifically for household battery storage and photovoltaic energy systems. Offering a wide selection of battery voltage options (25.6V, 48V, 51.2V) and capacities from 100Ah to 300Ah battery models, these LiFePO₄ batteries deliver ultra-long 6000 cycles at 100% DOD, backed by a 5‑year warranty and a design life exceeding 10 years. Unlike traditional tubular batteries with normal, flat, lead-acid, or deep-cycle batteries, the SL series provides higher energy density, faster charging, and maintenance‑free operation. With wall‑mountable compact design, built‑in LCD display, and seamless communication (CAN/RS485/RS232) with various hybrid inverters.
1. 6000 Ultra‑Long Cycle Life & Superior Safety
Technical core: LiFePO₄ chemistry delivers >6000 cycles at 25°C, 100% DOD – far exceeding traditional lead‑acid or tubular batteries.
User value: 10+ year design life with minimal capacity fade. No more frequent replacements, lower total cost of ownership, and inherent thermal stability for absolute safety.
2. Flexible Battery Voltage & Capacity Options
Technical core: Available in 25.6V, 48V, 51.2V nominal voltages and capacities from 100Ah to 300Ah (e.g., SL‑51.2300: 51.2V 300Ah = 15.36kWh).
User value: You can precisely match the battery to your inverter and energy needs – from small off‑grid cabins to whole‑home backup. Easily convert 300Ah battery capacity into watts, Wh, kWh, or runtime for accurate system sizing.
3. High Charge/Discharge Current for Solar Systems
Technical core: Supports up to 100A continuous charge and 200A continuous discharge (depending on model), ideal for high‑power PV and hybrid inverters.
User value: Rapid energy storage during sunny hours and instant high‑power output for heavy appliances (air conditioners, pumps, EVs) – maximizing self‑consumption of solar energy.
4. Wall‑Mountable Design & LCD Display
Technical core: Compact, space‑saving wall‑mount enclosure with an integrated LCD screen showing real‑time voltage, current, SOC, and temperature.
User value: Easy installation in garages or utility rooms. At‑a‑glance status monitoring without needing a separate app or meter.
5. Intelligent BMS with Multi‑Protocol Communication
Technical core: Built‑in BMS with CAN, RS485, and RS232 ports; standard communication protocol works seamlessly with SOROTEC and many other hybrid inverters.
User value: Plug‑and‑play integration with your existing or new energy storage system. Real‑time battery data sharing ensures optimized charging and longer battery life.
6. Comprehensive Protection for Worry‑Free Operation
Technical core: Multi‑layer protections against over‑charge, over‑discharge, over‑temperature, over‑current, and short‑circuit.
User value: the battery automatically shuts down under fault conditions, protecting both the battery and your connected equipment. IP20 rating suitable for indoor installations.
