SolarEdge Power Optimizer P750
The SolarEdge P750 is a single-input add-on optimiser for one high-power solar panel per optimiser.
Developed for commercial roofs and large fields with three-phase SolarEdge inverters (SE16K and larger). You get
panel-level MPPT, SafeDC™ (±1 V in standby) and a 25-year warranty, with single-bolt mounting and fewer BOS components
thanks to longer string lengths.
For high-power & bifacial
Up to 750 W per optimiser, supports 20 A Isc—ready for modern TOPCon/bifacial modules.
High efficiency
Max. 99,5% (weighted 98,6%) for minimal conversion losses.
Safe & robust
SafeDC™, IP68, −40…+85 °C and VDE-AR-E 2100-712 fire safety.
Fast installation
One bolt on rail/frame, MC4 in/out and a long outgoing plus cable for a tidy series route.

Design & compatibility
- Inverters: three-phase SolarEdge SE16K, SE17K, SE25K, SE27.6K, SE30K, SE33.3K, SE40K (Synergy equivalents as well).
- String rules: min. 14 and max. 30 optimisers per string (typical, depending on type).
- Mixing: within one string only P750 with P750; do not mix P- and S-series in new installations.
- Power limits: see the datasheet for the max. (continuous/connected) string power per inverter type.
Installation tips
- Mounting – fasten with one bolt to the rail or frame; leave ventilation space underneath the panel.
- DC side – use MC4, click fully home (pull test), check polarity and insulation resistance.
- Module choice – connect one module per P750; mind the 60 V Voc limit and 20 A Isc.
- String design – design for frost Voc and observe the min/max string length; verify in SolarEdge Designer.
- Commissioning – follow the SolarEdge procedure; module mapping and SafeDC check before switching on.
