What Is String‑Type PCS Boost Integrated Unit for C&I Energy Storage

For commercial‑industrial solar‑plus‑storage projects, many users struggle with large footprint, complicated wiring and energy loss from separate equipment. Our string‑type PCS & boost integrated unit is built for C&I energy‑storage scenarios. It combines power conversion and voltage boost in one single unit for simpler installation and higher efficiency.

What Is This Unit?

Simply put, it works as the core hub and bridge for commercial‑industrial energy‑storage systems. It connects solar PV or battery packs on one side and links to the power grid on the other. It handles bidirectional charge‑discharge control for energy storage, and steps‑up low‑voltage power to grid‑required medium voltage. One unit replaces two separate devices. It saves floor space, cuts field wiring and lowers total project cost.

Core Benefits

✅ High integration, smaller footprint

It fully integrates PCS, step‑up transformer and monitoring module. Its size is 30% smaller than traditional split‑setup solutions. Perfect for space‑limited C&I rooftops and power‑distribution rooms. You can place it in a corner without occupying valuable area.

✅ High efficiency for better revenue

Conversion efficiency reaches ≥98% to minimize charge‑discharge loss. It supports string‑level independent power control for each battery string. It stores surplus PV power fully and delivers stable discharge output, maximizing your profit from peak‑valley price arbitrage.

✅ Smart adaption, user‑friendly operation

Built‑in intelligent monitoring platform. You can check real‑time status including energy volume, power output and revenue data via mobile phone or PC. Multiple working modes are available: self‑consumption, peak‑valley arbitrage and demand‑side regulation. You can switch modes flexibly according to project requirements.

✅ Easy installation & maintenance

Pre‑commissioned in factory. On‑site work only requires limited cable connections. Modular structure allows unit‑level replacement without full‑system shutdown. It cuts maintenance time by half.
