Flexo 50: The All-in-One BESS for Space-Constrained C&I

Beyond the "Project" Mentality—A Standardized Product for Global Energy Autonomy

Traditional Commercial & Industrial (C&I) storage often comes with hidden burdens: oversized footprints, complex multi-cabinet wiring, and expensive on-site commissioning.

Flexo 50 was built to challenge that default. It is not a "shrunken" utility system; it is a productized solution engineered for the specific realities of small-to-medium commercial sites—where space is tight, timelines are compressed, and reliability is non-negotiable.

1. Compact Design: Fits Where Others Won't

In retail, hospitality, and light industrial sectors, the biggest hurdle to energy storage is often the floor plan. Traditional systems require significant clearance on all sides, turning a battery install into a spatial negotiation.

• Under 1.2 m² Footprint: Integrated PCS, EMS, and battery clusters in a single, sleek enclosure.

• Zero-Clearance Installation: Designed for back-to-wall and corner placement. This allows you to utilize "dead space" in utility rooms, basements, or corridors.

• Environmentally Rugged: With an IP55 rating and C4 anti-corrosion protection, the Flexo 50 is built for the dust of industrial zones, the humidity of Southeast Asia, and the salt air of coastal Europe.

2. A "Product," Not a Construction Project

The "last mile" of a BESS project—cranes, complex wiring, and multi-vendor coordination—can erode your margins. Flexo 50 is engineered to compress the installation timeline from days to hours.

• Factory Pre-Assembled: Arrives as a complete system. No "on-site puzzles."

• Live Transportation: Batteries are pre-installed at the factory, minimizing manual module handling on-site.

• Hand-Forklift Accessible: Deployable in locations where heavy cranes cannot reach or are too expensive to hire.

• Simplified Wiring: Installers focus on AC and load-end connections, significantly reducing commissioning errors.

3. Four-Layer Safety Architecture

Safety is a core system behavior, not an afterthought. Flexo 50 implements protection at every level of the energy stack:

1. Cell Strategy: Uses 100Ah cells specifically selected for their superior thermal surface-area-to-volume ratio, ensuring predictable heat dissipation.

2. Advanced BMS: Our self-developed BMS features active cutoff logic with SOC accuracy of ≤2%, reducing imbalance-driven aging.

3. Thermal Management: Integrated cooling keeps cell temperature differentials within 8°C, preventing the "hotspots" that lead to degradation.

4. Active Suppression: Dual-sensor detection (smoke + heat) coupled with an internal aerosol suppression system for rapid fire containment.

4. Multi-Mode Versatility

Small C&I customers need a system that works as hard as they do. Flexo 50 adapts to your site’s specific energy logic:

• PV Optimization: Supports 200% DC oversizing and a low start-up voltage to extend your daily generation window.

• UPS-Grade Continuity: A ≤10ms switching time ensures that critical loads stay online during grid transitions without a flicker.

• Hybrid Coordination: Seamlessly integrates with existing diesel generators or functions as a core node in a Microgrid/VPP pathway.

Project Planning Checklist

Before proposing a 30kW/50kWh system, ensure your site meets these criteria:

• [ ] Access: Can a hand-forklift navigate the door widths and corridors?

• [ ] Electrical: Have critical loads been prioritized for the 30kW output?

• [ ] PV Mapping: Is the string configuration compatible with the 150–850V input range?

• [ ] Environment: Does the site require the C4 anti-corrosion package (coastal/industrial)?
