All in One JA Solar BluePlanet C&I Energy Storage System 261kWh Battery 125kW Inverter Factory‑built, liquid‑cooled C&I battery cabinet with 261kWh LFP storage and 125kW three‑phase inverter in one unit. Designed for peak‑shaving, backup and self‑consumption on commercial and industrial sites with demanding operating conditions. TripleGuard safety with multi‑tier fire protection, explosion‑resistant design and real‑time thermal runaway warning. Brief description The JA Solar BluePlanet BP‑ES‑125kW‑261kWh‑B02 is an all‑in‑one commercial and industrial energy storage system combining 261kWh of high‑voltage LFP batteries with a 125kW three‑phase AC inverter in a single liquid‑cooled outdoor cabinet. It is built for high cycling, predictable performance and enhanced safety on C&I sites. With round‑trip efficiency up to 88%, millisecond‑level response and advanced SOX management, the BluePlanet system supports peak‑shaving, load‑shifting and backup across a wide operating temperature range from −30°C to +50°C. Liquid cooling maintains battery temperature below 35°C and reduces temperature variance, helping extend battery life and cut auxiliary power use. Key features All‑in‑one C&I ESS – 261kWh nominal LFP battery storage and 125kW three‑phase AC inverter integrated in one IP55 outdoor cabinet. Enhanced safety – TripleGuard Safety with three‑tier fire protection, explosion‑proof design, pack‑level detection and real‑time thermal runaway warning. Liquid‑cooled performance – Liquid cooling keeps batteries at ≤35°C, limits temperature variance to ≤3°C and reduces auxiliary power consumption by about 10%. Long‑life LFP cells – 314Ah LFP cells, depth of discharge up to 95% and cycle life of over 8000 cycles for long‑term use. Smart O&M – AI‑driven predictive maintenance and remote resolution can address around 90% of issues via software updates, reducing downtime and site visits. Where to use this system This BluePlanet 261kWh / 125kW system suits logistics centres, warehouses, manufacturing sites, data hubs and larger commercial buildings looking to cut peak demand, support critical loads and improve resilience. It can form part of a wider microgrid with solar PV, or operate as a standalone storage asset for time‑of‑use optimisation. Because this is a high‑voltage, three‑phase C&I energy storage cabinet with liquid cooling, fire suppression and grid‑connected inverter, it must be designed, installed and commissioned by qualified engineers and trusted partners familiar with UK grid codes and C&I battery standards. Energian can support system design and coordinate installation via specialist contractors. Technical specifications Advantages Safety – Millisecond‑level response with real‑time insulation monitoring. TripleGuard Safety including three‑tier fire protection, explosion‑proof design and pack‑level detection. Real‑time thermal runaway warning. Cost efficiency – Higher ROI with long‑life LFP batteries and high‑precision SOX (state of charge and health) management. System round‑trip efficiency (RTE) up to 88%. Liquid cooling maintains batteries at ≤35°C, reduces temperature variance to ≤3°C and cuts auxiliary power consumption by about 10%. Reliability – AI‑driven predictive maintenance can reduce downtime by up to 90%. Remote resolution can fix about 90% of issues via software updates. Modular design enables rapid component replacement and improves service efficiency. Model Model: BP‑ES‑125kW‑261kWh‑B02. DC side Nominal energy: 261kWh. Cell capacity: 314Ah LFP.
