Overview

Engineered specifically for South African commercial premises, agricultural operations, manufacturing workshops, and high-demand facilities, this turnkey three-phase high-voltage (HV) backup bundle delivers clean solar energy generation, rapid load-shedding immunity, and maximum demand peak shaving.

Combining Solis’s commercial-grade 30kW HV hybrid architecture, ESENER’s modular 1C-rated high-voltage lithium storage system, and a massive 30.24kWp array of Seraphim 630W N-Type TOPCon bifacial modules, this bundle bridges the gap between light commercial setups and heavy utility infrastructure. It runs high-draw inductive equipment—including cold storage compressors, irrigation pumps, CNC machinery, and large HVAC units—without downtime or voltage dips.

Key System Highlights

• Seamless Load-Shedding Resilience: Under 10ms transfer time provides true uninterruptible power supply (UPS) performance for mission-critical IT servers, processing lines, and sensitive medical or office equipment.

• Heavy Motor & Inductive Start Capability: Delivers 160% short-term overload power (48kW for 2 seconds) during backup mode to effortlessly absorb high inrush currents from three-phase industrial motors and compressors.

• Bifacial Solar Yield: Equipped with 48 Seraphim 630W modules featuring N-Type TOPCon cell technology and up to 80% bifaciality, capturing reflected ambient light from rooftops or ground mounts to increase total daily yield beyond nominal plate ratings.

• 1C High-Voltage Efficiency: High-voltage battery integration (150V–800V operating window) minimizes DC transmission losses and cable thickness compared to low-voltage 48V banks, supporting full 1C charge/discharge rates for rapid recovery during short grid availability windows.

• Peak Shaving & Generator Automation: Built-in intelligent energy management features automated generator synchronization (6kW–30kW dry contact start/stop) and peak shaving schedules to cut maximum demand utility charges on municipal tariffs.

• Utility-Approved Compliance: Fully certified to NRS 097-2-1 standards for legal grid interconnection across South African municipalities and Eskom networks.
