SolarEdge Power Optimizer P950

The SolarEdge P950 is a powerful optimiser for one or two (high-power or bifacial) PV modules connected in series. It maximises energy yield per panel, reduces mismatch losses and adds panel-level safety and monitoring—ideal for commercial rooftops and large-scale installations.

Why choose the P950?

• Maximum yield per panel thanks to module-level MPPT (efficiency up to 99.5%).
• Longer strings, fewer components and therefore lower BOS costs.
• SafeDC™: automatic voltage reduction to ~1 V per optimiser upon shutdown for added safety.
• Panel-level monitoring for rapid fault diagnosis and reduced downtime.
• IP68 and −40 °C to +85 °C—performs effortlessly in harsh conditions.

Key specifications

• Nominal PV input power: 950 W
• MPPT range: 12.5–105 V • Max. Voc (per input): 125 V
• Max. module short-circuit current (Isc): 14 A
• Max. output current: 18 A • Max. output voltage: 80 V
• Protection rating: IP68 • Operating temperature: −40…+85 °C
• Dimensions/weight: approx. 129 × 162 × 59 mm / ~1.06 kg
• Connectors: MC4-compatible, pre-assembled input/output cables

Design & compatibility

• For one or two PV modules in series (including high-power/bifacial).
• For use in strings with P-series optimisers (P800p/P850/P950/P1100) and SolarEdge 3-phase inverters (SE16K and larger).
• Typical string limits: minimum ~14 and maximum 30 optimisers per string (depending on inverter/grid).

Installation tips (for the installer)

1. Mount the optimiser using a single mounting point; route cables neatly and without tension.
2. Check the Voc at the lowest design temperature and remain below the 125 V limit per input.
3. Ensure MC4 connectors are fully engaged (click/pull test) and check polarity and insulation resistance.
4. Route strings by orientation/shadow zone to separate MPP channels on the SolarEdge inverter.
5. Avoid unnecessary heat: install away from the hottest zones where possible; take into account thermal derating > ~70 °C.

Application

Perfect for commercial rooftops and ground-mounted installations with long strings, mixed orientations or (partial) shading. The P950 delivers more kWh per m², enhances safety and simplifies maintenance through panel-level monitoring.
