Sungrow SH15T 15 kW Commercial 3‑Phase Hybrid Inverter 15 kW three‑phase hybrid inverter for small commercial and logistics sites needing reliable backup and self‑consumption. The Sungrow SH15T 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 SH15T 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 50 A fast charge / discharge for peak‑shaving and backup. Built‑in 63 A bypass and 10 ms seamless switch for whole‑load or critical‑load backup when installed with suitable switchgear. The Sungrow SH15T is a 15 kW three‑phase hybrid inverter designed for small commercial premises with three‑phase supplies. It combines high‑voltage PV input with a lithium battery connection to provide grid‑tied operation, backup supply and flexible energy management in one compact unit. Typical applications include small warehouses, workshops, retail units and offices looking to cut grid consumption and keep key services running during power cuts. Sungrow SH15T key features 15 kW three‑phase hybrid operation with recommended max. PV input power of 30 kWp and lithium battery support. Support 100 % unbalance output in backup and on‑grid mode, suitable for mixed three‑phase and single‑phase loads. Three independent MPPTs, up to 1000 V DC input, max. 16 A per string and 80 A total PV input current. Outdoor‑ready IP65/C5 enclosure and quiet operation with natural convection cooling. Integrated protections including DC/AC surge protection (Type II), AFCI, anti‑islanding, leakage current and reverse polarity protection. Typical commercial applications The SH15T suits rooftop PV and battery systems on small warehouses, light industrial units, trade counters and office buildings where a three‑phase supply and resilient power are important. Paired with compatible lithium batteries, it can support 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 introduce 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.
