M-07, IEEE 1547-2018, Rule 21, Rule 14 (HI), FCC Part 15 Class A ### Pros - **Modular Architecture with Built-In Redundancy** - The inverter consists of three independent Synergy units - a failure in one does not interrupt production from the remaining units. Servicing involves replacing a single module without disconnecting the entire installation, minimizing downtime at C&I sites where every hour of lost production translates directly to revenue loss. - **98% European Efficiency (98.3% Peak)** - According to the official EU datasheet (models SE66.6K-SE120K for 400 V grids), European efficiency is 98%, with a peak of 98.3%. Under typical Polish irradiance conditions - characterized by a high proportion of partial-load hours - the EU weighted efficiency figure is a direct indicator of real annual energy yield, outperforming competitors that achieve 97-97.5% EU efficiency. - **Integrated SafeDC and Arc-Fault Detection** - SafeDC automatically reduces DC voltage to ~1 V at the optimizer level upon grid disconnection, certified to IEC/EN 60947-1, IEC/EN 60947-3, and VDE AR 2100-712. The integrated Arc-Fault Circuit Interrupter (AFCI) instantly interrupts production at the module level - a critical safety feature for industrial facilities subject to enhanced fire protection requirements. - **DC Oversizing up to 175% and Pre-Commissioning via SetApp** - The ability to connect DC capacity up to 175% of the inverter's AC rating reduces the levelized cost of the investment and optimizes energy yield during morning and evening hours. SetApp enables full system verification - wiring, DC polarity, communications - from a smartphone prior to grid connection, shortening commissioning time and reducing first-startup service costs. - **Module-Level MPPT with Power Optimizers** - In a SolarEdge optimizer-based architecture, each module operates at its own independent maximum power point. For complex C&I installations with multiple roof sections, varying orientations, or partial shading - such as from HVAC equipment - this delivers measurably higher energy yield compared to string inverters with 2-4 MPPT inputs at the inverter level. ### Cons - **Manufacturer Financial Health - Long-Term Risk** - SolarEdge conducted four rounds of layoffs in 2024-2025 (approximately 2,200 positions in total), shut down its energy storage division, reported a ~64% year-over-year revenue decline in Q3 2024, and replaced both its CEO and CFO. For C&I installations backed by 12-20 year warranties, this represents a tangible long-term risk to warranty support continuity and spare-parts availability. - **SolarEdge Ecosystem Vendor Lock-In** - The Synergy series requires SolarEdge power optimizers exclusively - it is incompatible with third-party solutions such as Tigo or Huawei SolarMate. The cost of power optimizers (typically 100-150 PLN per unit) significantly increases total system CAPEX compared to string inverters without optimizers, such as the Fronius Tauro or SMA STP 50-150. Any future system upgrade or expansion leaves the customer fully dependent on SolarEdge pricing. ## About this series The SolarEdge Synergy series comprises three-phase grid-tie inverters specifically designed for large commercial and industrial installations, where rapid deployment, high availability, and safety are key priorities. Its distinguishing feature is the **modular design**-the inverter consists of multiple independently operating Synergy units and a master management module, facilitating service and minimizing downtime during failures. In conjunction with SolarEdge power optimizers, the system achieves **module-level maximum power point tracking (MPPT)**, effectively functioning as multiple MPPT units-aiding performance during shading, varying roof tilts, and uneven module aging. High **European efficiency** ensures superior energy production under typical operating conditions in Poland, beyond laboratory settings. Monitoring is accessible via the portal and application (SetApp), and communication can be achieved through **Ethernet** or remote solutions. Notable built-in safety features include, among others, DC voltage reduction (SafeDC) and arc detection. The series is designed for commercial and industrial (C&I) applications and requires a SolarEdge architecture with optimizers-typically paired with dedicated SolarEdge energy storage solutions. ## Questions ### What types of installations are SolarEdge Synergy inverters designed for, and what output power ratings are available? The SolarEdge Synergy series is designed exclusively for larger commercial and industrial (C&I) installations. Available models include the SE50K, SE66.6K, SE90K, SE100K, and SE120K, covering AC output power ratings from 50 kW to 120 kW. This solution is intended for manufacturing facilities, warehouses, office buildings, and shopping centers - it is not designed for typical residential prosumer installations on single-family homes. ### What is the modular architecture of the Synergy inverter, and why does it matter in the event of a failure? The Synergy inverter consists of several independent power units and a single master control module. If one power unit fails, the remaining units continue to generate energy and the installation does not come to a complete stop. Replacing the failed module is faster and less costly than replacing the entire inverter. This directly translates to higher annual energy yield and reduced downtime in commercial facilities. ### Does the SolarEdge Synergy inverter require power optimizers, and can it be connected without them? Yes, the Synergy series is designed exclusively to operate within the SolarEdge architecture with power optimizers. It cannot be used with conventional string wiring without optimizers. Power optimizers provide module-level MPPT, which is especially important in cases of shading, varying roof orientations, or mixed panel types within a single installation. ### What is the standard warranty on the SolarEdge Synergy inverter, and can it be extended? The standard manufacturer's warranty on the Synergy series inverters is 12 years. SolarEdge offers the option to extend coverage to 20 or 25 years for an additional one-time fee, provided the extension is purchased within 24 months of the inverter's ship date. In the event of a covered warranty claim, the manufacturer typically ships a replacement unit within 48 hours. ### What is the SafeDC feature in the Synergy series, and is it required under Polish fire safety regulations? SafeDC is a built-in safety function that, upon inverter shutdown or grid loss, automatically reduces the DC string voltage to a safe level of 1 V in under one minute. This eliminates the risk of electric shock for firefighters or service technicians. Polish standards and DGUV regulations increasingly require rapid shutdown systems in commercial buildings, and SafeDC satisfies these requirements. ### How does monitoring work with the SolarEdge Synergy inverter, and can it be integrated with BMS systems? Monitoring is carried out via the SolarEdge monitoring portal and the SetApp mobile application, which enables configuration and diagnostics directly on-site without a laptop. Connectivity to the local network is available via Ethernet or remote communication modules. The inverter also supports industrial protocols - including Modbus - enabling integration with building management systems (BMS) or industrial automation platforms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/se-three-phase-inverter-with-synergy-technology-made-in-the-0f50ee5853b5.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Ginlong Solis S5-GC110K](https://comparepv.com/inverter/ginlong-solis-s5-gc110k) | 110 kW | 98.6% | 10 | 91.0 kg | 59.0 kg heavier | | [Solis-110K-HV-5G](https://comparepv.com/inverter/ginlong-solis-solis-110k-hv-5g) | 110 kW | 98.5% | 9 | 82.0 kg | 50.0 kg heavier | | [Growatt MAX 110KTL3-X LV](https://comparepv.com/inverter/growatt-max-110ktl3-x-lv) | 110 kW | 98.4% | 10 | 84.0 kg | 52.0 kg heavier | | [SMA Solar Sunny Tripower CORE2 STP 110-60](https://comparepv.com/inverter/sma-solar-sunny-tripower-core2-stp-110-60) | 110 kW | 98.4% | 12 | 93.5 kg | 61.5 kg heavier | | [SOFAR 125KTLX-G4](https://comparepv.com/inverter/sofar-solar-sofar-125ktlx-g4) | 110 kW | 98.3% | 10 | 75.0 kg | 43.0 kg heavier | | [Ginlong Solis S6-GC110K](https://comparepv.com/inverter/ginlong-solis-s6-gc110k) | 110 kW | 98.3% | 10 | 96.0 kg | 64.0 kg heavier | | [Deye SUN-110K-G03](https://comparepv.com/inverter/deye-sun-110k-g03) | 110 kW | 98.3% | | 81.0 kg | 49.0 kg heavier | | [Growatt MAX 110KTL3-X2 LV](https://comparepv.com/inverter/growatt-max-110ktl3-x2-lv) | 110 kW | | 8 | 84.0 kg | 52.0 kg heavier | --- Source: https://comparepv.com/inverter/solaredge-se110kus
