SolarEdge P850 Optimiser 850W MC4 2x High Power/Bi-facial 2.2m with 1.3m input length
P850-2.2-LI-1.3-MC4 | Dual-input commercial power optimizer for two high-power or bifacial modules in series, rated to 850 W with 1.3 m long inputs and 2.2 m output lead for flexible layouts.
Key Features
- Designed for use with SolarEdge three-phase commercial inverters.
- Connects two high-power or bifacial modules in series to one optimizer for reduced BOS cost.
- Supports up to 850 W total input power (typically up to ~425 W per module, subject to design limits).
- Extended 1.3 m input leads for flexible connection to large-format or split-junction-box modules.
- 2.2 m output cable length for convenient string routing back to trunk cable or DC combiner.
- Module-level MPPT for mismatch and shading mitigation, improving energy yield.
- High peak efficiency around 99.5% for minimal conversion losses.
- SafeDC rapid shutdown for enhanced installer and firefighter safety.
