Sunsynk C&I System: 2 x 50kW 3-Phase Hybrid Inverter with 245.76kWh Battery (Hybrid ESS)

• Two Sunsynk 50kW three-phase hybrid inverters give a combined 100kW AC output for commercial and industrial sites.
• The 245.76kWh battery system is based on Sunsynk high-voltage 5.12kWh LFP rack modules for scalable energy storage.
• Suitable for sites needing grid support, peak shaving, backup power, or better use of on-site solar generation.

Product overview

This Sunsynk C&I energy storage system combines two 50kW three-phase hybrid inverters with a 245.76kWh high-voltage battery bank consisting of 48x Sunsynk 5.12kWh Single Battery Unit for HV Series. It is a practical option for warehouses, logistics centres, agricultural operations, and other commercial sites that need reliable storage with three-phase integration. Installation should be planned with a trusted partner, and UK expert support is available from Energian for specification and project guidance.

Key features

• Three-phase hybrid inverter platform with up to 65kW max DC input power per 50kW unit.
• High-voltage battery architecture with LFP chemistry and rack-mount system design.
• IP65 inverter enclosure for outdoor or plant-room installation flexibility.
• Battery system cycle life stated as 6,000 cycles at 25°C, 0.5C/0.5C, EOL 70.
• UK expert support available by phone, email or live chat, with in-person consultation available at our office.

Applications

Typical uses include peak shaving, solar self-consumption, backup support for essential circuits, and load management on sites with three-phase demand. It may also suit commercial buildings, farm buildings, workshops, and distribution facilities where reliable storage and grid interaction are require.
