When your facility needs predictable savings and resilient power, modular high-voltage storage makes the math work. The WECO 16K0 HV platform builds from a 16.0 kWh rack module into cabinet- or room-scale systems, delivering clean expansion from hundreds of kilowatt-hours to multi-MWh—without locking you into a single project size.

What it is (in one minute)

• Base building block: 16.0 kWh industrial rack module (LFP), nominal 51.2 V per module. Multiple modules are stacked/series-connected into a high-voltage string under an HV controller. 

• Scales fast: From single strings to staged cabinets—WECO lists ranges up to 273 kWh per system on partner pages and up to multi-MWh across cabinets. 

Why facilities choose the 16K0 HV

1) Modular today, expandable tomorrow

Add strings or cabinets as load grows—no forced redesign. WECO’s HV family is explicitly designed for seamless expansion.

2) High-voltage efficiency

Series strings minimize DC current and cable losses, improving round-trip efficiency at the plant level versus equivalent low-voltage parallels (especially at C&I power levels). (General principle; controller is HV-oriented per datasheet.)

3) Built-in safety & battery care

Datasheet highlights three protection levels, real-time balancing, and adaptive 3-step charging—key to cycle life and warranty outcomes in hot, dusty regions.

4) Ready for smart operations

Integrated Wi-Fi/Bluetooth simplifies commissioning and ongoing monitoring; CAN-based logic coordinates with the inverter for charge/discharge windows and limits.

Where it fits best

• Peak-shaving & demand control for malls, warehouses, factories.

• Solar self-consumption to capture midday PV and shift to evening.

• Backup for critical loads (IT rooms, cold chains, POS).

• Stepwise portfolio rollouts where sites are added quarterly.

Architecture at a glance

1. Modules (16.0 kWh each) → stacked into an HV string

2. HV BOX controller → protection, balancing, comms (mandatory)

3. Hybrid/PCS inverter (HV-compatible) → site AC bus

4. EMS/Monitoring → Wi-Fi/Bluetooth + CAN integration for dispatch and reporting

Key specs (from WECO sources)

• Capacity per module: 16.0 kWh; Nominal voltage: 51.2 Vdc (module level). 

• System scale: up to 273 kWh (typical cabinet sets) to multi-MWh (fleet), depending on strings/cabinets. 

• Controls & protection: HV BOX required; 3-level protection, real-time balancing, adaptive charge logic. 

• Comms: Wi-Fi, Bluetooth, CAN for inverter/EMS coordination. 

(Always verify final ratings, current limits, and string counts against the latest WECO datasheet for your SKU and regional code set.) 

Deployment tips (handy for your EPC/installer)

• Right-size the PCS to your peak kW and tariff windows; leave DC headroom for future cabinet additions.

• Thermal & dust controls: Site batteries in conditioned or filtered enclosures; follow WECO’s environmental specs from the datasheet.

• Comms first: Plan CAN addressing and EMS tags ahead of energization—saves days later.

• Lifecycle plan: Use the adaptive charging windows and balance routines to protect throughput kWh (warranty KPI).

Bottom line

If you need a repeatable C&I storage block that can start under 300 kWh and scale to multi-MWh, the WECO 16K0 HV architecture hits the sweet spot: modular capacity, HV efficiency, smart controls, and clear protection layers—backed by documentation and monitoring that make portfolios easier to operate.
