Description
The UP-S delivers full power with no derating at 35 °C. Its power stage uses SiC MOSFETs, peak efficiency reaches 99.45% against 98.8% for the UP and UP-XT, and the firmware supports grid-forming operation and black start. All versions are cooled by OptiCool moving 6,500 m³/h of air, with IP54 electronics. Grid functions include Q(U), P(f), FRT ride-through, peak shaving and energy shifting. The battery connects through a DC load-break switch, and the cabinet has insulation monitoring and type I surge arresters. When shipped with a substation, a ready PCS block with transformer arrives on site. The unit weighs up to 3,700 kg at 2815 × 2318 × 1588 mm and sits on a prepared foundation.
How to choose
For arbitrage and peak shaving on a strong grid, the UP or UP-XT is enough. An island, microgrid or project that demands black start needs the UP-S with grid-forming and VDE-AR-N 4130. On a hot site size by the 50 °C rating, 3,400–3,910 kVA for the UP-XT and 2,640–4,140 kVA for the UP-S. The nominal AC voltage of 600, 630, 660 or 690 V is matched to the transformer winding. A smaller, modular BESS is easier to build on the Sunny Highpower Storage string inverter at 100–180 kVA.
