SolarEdge S1000 Power Optimiser – 1000W Module-Level Output

SolarEdge S1000 Power Optimiser: The Efficient Module-Level Solution for Commercial PV Systems

Designed for commercial and large field installations, the SolarEdge S1000 Power Optimiser delivers enhanced energy yield, built-in safety, and flexible design options. With support for up to two high-power or bifacial modules, it enables optimised performance at the module level, maximising your system’s output while reducing overall costs.

Greater Yields with Module-Level MPPT

The S1000 uses independent maximum power point tracking (MPPT) per module, meaning energy harvest is optimised across every panel, even in shaded or mismatched conditions. This helps to increase overall system output and accelerate return on investment.

• 99.5% peak efficiency and 98.8% weighted efficiency
• Compatible with high-output and bifacial PV modules
• Minimises mismatch losses across the array

Built-In Safety with SafeDC™ and Sense Connect

To protect both installers and equipment, the S1000 includes automatic DC voltage shutdown with SolarEdge’s SafeDC™ technology. The integrated Sense Connect feature offers real-time temperature and connection monitoring, automatically alerting to abnormal heat levels or wear, helping to prevent potential faults or hazards.

Flexible Design and Lower BoS Costs

With support for up to two modules in series, the S1000 allows longer strings, better roof coverage, and fewer components such as fuses and combiner boxes. Installers benefit from quicker setups and lower balance of system (BoS) costs.

• Supports 50% fewer cables and accessories
• Compatible with all SolarEdge commercial three-phase inverters
• IP68-rated for harsh environmental conditions

Remote Monitoring and Simpler Maintenance

The S1000 enables full module-level visibility through SolarEdge’s monitoring platform. Faults can be quickly pinpointed and resolved remotely, reducing site visits and minimising downtime, particularly useful for large commercial sites with high system complexity.

Why Evergy Recommends This Product

The SolarEdge S1000 offers the perfect blend of performance, safety, and cost-effectiveness. We recommend it for commercial-scale PV systems looking to maximise return without compromising on safety or install time. It’s also a strong choice for use alongside bifacial panels or where string layout needs maximum flexibility.

FAQs

Can the S1000 be mixed with the S1200 in the same string?
No – each string must consist of the same model of optimiser to ensure system compatibility and safety.

What inverters is this compatible with?
All SolarEdge commercial three-phase inverters, including SE16K–SE40K models.

Does it support bifacial modules?
Yes, the S1000 supports high-output and bifacial PV panels, making it ideal for modern commercial installs.
