The WeCo 5K3‑XP is a high-quality 5.37 kWh lithium iron phosphate (LiFePO₄) battery module operating at approximately 48 V (nominal ~51.2 V). It supports both low-voltage (LV) and high-voltage (HV) solar system integrations, making it versatile for residential and commercial installations. With built-in communication via Wi‑Fi + Bluetooth, users can monitor battery status seamlessly through WeCo’s mobile app and web portal.

⚙️ Key Features

🔋 Battery & Capacity

• Usable energy: 5.37 kWh, approx. 105 Ah at 52 V.

• Expandable in modular clusters—up to 8 modules in parallel (LV) or multi-cluster high-voltage systems (e.g. up to ~79.5 kWh).

🔄 Expandability & Voltage Flexibility

• Dual-voltage capability: low-voltage (~48 V nominal) or high-voltage via series clusters.

• For LV mode: up to 8 in parallel without expansion hub; with hub, you can build extensive clusters. For HV mode: stack modules in series (2–16) to reach up to ~928 V system voltage.

📡 Connectivity & Smart Monitoring

• Integrated Wi‑Fi and Bluetooth modules enable remote monitoring via the WeCo Batteries app and web platform. Requires an optional Wi‑Fi accessory to connect the battery to the internet/cloud.Standard communication ports include RS485, CAN, RS232 for connecting to compatible inverters or for local data access.

📈 Long Life & High Throughput

• Cycle life: 7,000+ full cycles, with 100% depth of discharge (DOD) and up to 1C charge/discharge rate.

• Features active cell equalizer to ensure consistent cell balancing for efficiency and lifespan preservation

🌡 Specifications & Environmental

• Operating temperature range: approx. –20 °C to +55 °C; storage: –10 °C to +50 °C; humidity: 5–95%.

• Protection rating: typically IP20 or IP21 depending on installation

🛡 Backup & Safety

• Built-in dual BMS, auto-contactor, fusing for both LV and HV circuits.

• Supports adaptive charging logic, protection against overvoltage/discharge, thermal faults, short-circuit, and more.

📏 Physical Specs

• Dimensions: approx. 580 × 463 × 156 mm; weight ~52 kg per module.

• Design life: ~15 years at 25 °C; warranty: typically 10 years.
