SolarEdge S500B Power Optimizer

SolarEdge S500B Power Optimizer – 500W (650W) S-Series Module-Level Optimizer for Residential Solar

The SolarEdge S500B is a high-performance S-Series Power Optimizer engineered for modern residential solar systems using higher-wattage modules. Attached directly to each solar panel, the S500B delivers module-level MPPT (Maximum Power Point Tracking), maximizing energy harvest while providing panel-level monitoring and enhanced safety.

With a rated input of 500W (upgradable to 650W for installations after August 1, 2024), the S500B supports today’s powerful residential modules and is ideal for complex roof layouts with shading, multiple orientations, or module mismatch.

Key Features and Benefits

• Rated Input DC Power: 500W (650W post-Aug 2024) — modules with up to +5% tolerance allowed
• Maximum Efficiency: 99.5% (weighted efficiency 98.6%)
• MPPT Operating Range: 12.5 – 105 Vdc
• Absolute Max Input Voltage (Voc): 125 Vdc
• Maximum Input Short Circuit Current (Isc): 15 A (adjusted up to 18.75 A for worst-case conditions)
• Maximum Output Voltage: 80 Vdc | Maximum Output Current: 15 A
• Sense Connect Technology — Advanced detection of abnormal PV connector behavior for improved safety and fire prevention
• SafeDC™ — Reduces voltage to 1V per optimizer during standby or when the inverter is off for installer and firefighter safety
• 100% Module-Level Monitoring — Real-time performance data for every panel via the SolarEdge app
• Compact Design — Dimensions: 129 × 165 × 45 mm | Weight: ~790 g
• IP68 / NEMA 6P rated for outdoor durability in extreme conditions (-40°C to +85°C)

Superior Energy Production

The S500B mitigates all types of power loss — from partial shading and soiling to manufacturing tolerances and panel aging. This results in significantly higher system yield compared to traditional string inverters, often adding 2–25% more energy production.

It works seamlessly with SolarEdge residential inverters (including the Home Hub Single SKU series) and is fully compatible with SolarEdge Home Battery storage and EV chargers.

Ideal for Residential Installations

• Roofs with shading, different orientations, or complex layouts
• Systems using high-power bifacial or monofacial modules
• New solar installations or retrofits requiring maximum optimization and monitoring
