More product details
Managing multi-megawatt commercial solar arrays across expansive factory roofs requires high string granularity. The integrated CH3-125K inverter provides 8 independent 32 A MPPT trackers (Isc 40 A), optimizing 16 strings of 600W+ bifacial modules.
- 8 MPPT channels allow dedicated tracking for diverse warehouse roof slopes with zero inter-string mismatch.
- Absorbs up to 187,500 W of solar generation, routing daytime power directly into industrial loads and storage.
- Delivers up to 189.9 A continuous three-phase AC output (137.5 kVA max) to handle heavy machine starts.
Precision liquid thermal loop for multi-cycle daily durability.
Sized for heavy daily commercial cycling, the integrated CB3-L261 container houses thirteen 20 kWh liquid-cooled modules using 280 Ah prismatic LFP cells. Direct liquid cooling plates beneath cells maintain temperature variance strictly within ≤2.5 °C. 931.8 V nominal operating bus minimizes DC transmission losses and thermal stress during 140 A cycling. Multi-sensor aerosol fire suppression, combustible gas detection, and emergency pressure relief vents.
