S6-GC(25-60)K-US

Ordering: S6-GC(25-60)K-US      
• APST (APS MLRSD Transmitter)  
• RSS (Tigo MLRSD Transmitter)  
• NEPT (NEP MLRSD Transmitter)  

S6-GC(25-60)K-US is the preferred PV string inverter for large commercial rooftop PV projects. The inverter features 3/4 independent MPPTs with very wide full-power operating ranges that can bring more yield. String current up to 20A, perfectly accommodates new high-power and bi-facial PV modules. Easy-to-use online O&M tools make O&M more intelligent and convenient. Optimized DC&AC interconnection will reduce the cost of system cables. Type 4X, CS Anti-Corrosion Level can be installed in the harshest environmental conditions.
