Sungrow PowerKeeper Series<\/strong> is the new ESS (Energy Storage System) for Commercial & Industrial (C&I) applications<\/strong>, now available in the VP Solar product portfolio.<\/p>\n

Based on the \u201cAce 007, Ace Profit\u201d<\/strong> concept, PowerKeeper Series has been developed to deliver zero waste, zero outage and maximum energy value optimisation<\/strong> through modular design, operational continuity and advanced energy management functions.<\/p>\n

PowerKeeper Series: modular energy storage system from 50 to 1,000 kWh<\/h2>\n

The Sungrow PowerKeeper solution uses modular battery units with a capacity of 12.48 kWh<\/strong>, enabling flexible system configurations from 50 kWh up to 1,000 kWh<\/strong>, with discharge durations configurable from 2 to 8 hours<\/strong>.<\/p>\n

The modular architecture allows the system to be precisely sized according to the actual energy requirements of the end user, avoiding oversizing while maintaining the possibility of expanding installed capacity as energy needs evolve.<\/p>\n

The solution integrates the SH125CX hybrid inverter<\/strong> and can be configured with multiple units connected in parallel for applications with different load profiles, from commercial facilities to higher-power industrial installations.<\/p>\n

Fast installation thanks to modular design<\/h2>\n

One of the key features of the PowerKeeper Series is its simplified installation process.<\/p>\n

The system can be supplied with a pre-assembled 50 kWh stack<\/strong>, designed to accelerate on-site installation activities, or with individual battery modules to be integrated into the required configuration. With an individual weight of approximately 90 kg<\/strong>, the battery modules are designed to simplify handling, replacement and future system expansion.<\/p>\n

The compact design also enables different installation layouts, optimising available space even in technically challenging environments.<\/p>\n

Energy backup with integrated ATS<\/h2>\n

In the C&I segment, power continuity is a critical requirement. PowerKeeper Series integrates an ATS (Automatic Transfer Switch)<\/strong> that enables the transition to off-grid mode in approximately 10 milliseconds<\/strong>, ensuring continuous power supply to connected loads.<\/p>\n

This feature makes the system suitable for applications where energy availability is essential, including manufacturing companies, commercial facilities, infrastructures with sensitive loads and backup power systems.<\/p>\n

Safety and reliability for outdoor applications<\/h2>\n

PowerKeeper Series is designed to ensure high reliability even in demanding environmental conditions.<\/p>\n
