Three-Phase High-Voltage ESS

BeSafe's HV series delivers commercial-grade energy storage in a modular cabinet — 30 to 60 kilowatts of three-phase output, 53 to 61 kilowatt-hours of LiFePO4 capacity, IP54 weatherproof enclosure. Drop it next to a building, on a farm, or on an island. No indoor room required.

30–60 kW Output 53–61 kWh Capacity Three-Phase 400 VAC IP54 Outdoor Multi-Level Fire Protection
Why three-phase high-voltage? Single-phase systems cap out around 10–15 kW. Three-phase HV systems at 358–460 VDC battery voltage handle 50–100 kW loads (HVAC, pumps, EV fast charging) with lower current — meaning thinner cables, less copper cost, and higher round-trip efficiency.

Engineered for Harsh, Real-World Deployment

Most "commercial" storage systems are essentially residential boxes painted black. BeSafe HV series was designed from the anchor bolts up for outdoor and industrial deployment — anchor-mountable, IP54 dust/water resistant, C3 corrosion-rated, with active air cooling that handles 55 °C ambient without derating.

Isolated Cluster Architecture

Each battery cluster operates independently with zero circulating current between packs. If one cluster develops a fault, the rest keep producing power — and a single bad pack cannot bring the whole system down.

Triple-Tier Fire Suppression

Pack-level aerosol suppression, cluster-level thermal runaway isolation, and cabinet-level smoke + heat detection with automatic fire suppressant release. Certified to multi-level fire protection standards.

Plug-and-Play Modular Cabinet

Pre-wired, factory-tested modules ship in a single cabinet. On-site work is limited to anchor bolting and AC/PV cable landing — typically a one-day installation with two technicians.

Embedded EMS + Cloud Sync

Built-in energy management system with configurable operating modes (peak shaving, self-consumption, time-of-use arbitrage, diesel-gen hybrid). Live data streams to mobile and web dashboards.

IP54 All-Weather Rating

Sealed against dust ingress and water jets from any direction. Operating temperature -20 °C to 55 °C. Anti-corrosion C3 finish for coastal and high-humidity sites.

96 kW PV Input, 4 MPPT

Accepts up to 96 kilowatts of solar input across four independent MPPT channels. Maximum DC voltage 1,000 V. Pair with commercial rooftop arrays or ground-mount farms without external combiners.

Models in This Series

H50 50 kW · 53.76 kWh Standard

Base model for medium commercial loads: small factories, office buildings, retail chains, agricultural operations. Three-phase 400 VAC output, anchor-mount cabinet.

Download H50 Brochure

H53 30 kW · 53.76 kWh 60 kW PV

Lower-output variant for sites with smaller loads but larger solar arrays. Same cabinet as H50, optimized for PV-heavy applications where daytime generation peaks but night loads are modest.

Download H53 Brochure

H50Pro 50 kW · 61.44 kWh 96 kW PV Recommended

Upgraded capacity and MPPT headroom. The most popular HV model — used in farms, microgrids, and commercial peak-shaving deployments worldwide.

Download H50Pro Brochure

H60 30 kW · 61.44 kWh 60 kW PV

Highest-capacity 30 kW model. For sites that need maximum storage duration at moderate continuous load — e.g., remote telecom hubs, off-grid resorts, or backup for essential building services.
