Sungrow SH25T 25 kW Commercial Hybrid 3‑Phase Inverter 25 kW three‑phase hybrid inverter for small commercial, light industrial and logistics sites needing reliable backup and self‑consumption. The Sungrow SH25T inverter requires a minimum of 3 and a maximum of 8 SBH050 (5.0 kWh) battery modules per SBH battery tower for stable operation with this inverter family. One or two 15-40kWh battery towers each can be connected to a single SH25T via a Y‑connector (parallel cable), with both towers required to be identical in model, module count, and size. Supports PV and lithium battery storage with fast 50 A charge / discharge for peak‑shaving and backup. Built‑in 63 A bypass and seamless switchover for whole‑load or critical‑load backup with compatible switchgear. The Sungrow SH25T is a 25 kW three‑phase hybrid inverter designed for commercial and industrial applications where uptime matters. It combines high‑voltage PV input with a lithium battery connection, providing grid‑tied operation, backup supply and flexible energy management in one compact unit. Typical uses include warehouses, retail units, offices and small industrial sites looking to reduce grid consumption and maintain power to critical loads during outages. Key features 25 kW three‑phase hybrid operation with recommended max. PV array size up to 50 kWp and lithium battery support. Built‑in 63 A bypass and backup function with rated backup power 25 kW / 25 kVA and peak output 36.5 kW / 36.5 kVA for 10 s (with sufficient PV / battery power). Three independent MPPTs, up to 1000 V DC input, and up to 16 A per PV string for modern high‑current modules. Indoor or outdoor wall‑mounted installation with IP65 enclosure and quiet operation suitable for commercial plant rooms and service areas. Integrated protections including DC/AC surge protection (Type II), anti‑islanding and leakage current protection, plus RS485, WLAN, Ethernet and CAN communications. Typical applications The SH25T is well suited to rooftop PV and battery systems on small warehouses, last‑mile logistics depots, chilled storage, trade counters and office buildings where three‑phase loads and backup are required. It can be used with compatible lithium battery banks for night‑time operation, peak‑shaving and short‑duration backup of lighting, IT, refrigeration and other critical services. Installation and UK support This inverter must be installed and commissioned by a suitably qualified electrician or solar installer, as part of a correctly designed three‑phase PV and battery system with appropriate protection, switchgear and grid approvals where required. Energian can connect you with trusted installation partners for full system design, installation and commissioning across the UK. UK expert support is available – contact Energian by phone, email or live chat for help with system sizing, compatibility checks and project support, or visit our office for an in‑person consultation.
