This translates into greater design flexibility for multi-orientation systems and improved yield compensation under partial shading conditions. - **98.5% Efficiency + IP66 + C5** - A peak efficiency of 98.5% ranks among the best in class for 110 kW string inverters. This is complemented by an IP66 enclosure with C5 anti-corrosion rating and DC Type I+II and AC Type II SPD surge protection, enabling installation in harsh environments - industrial zones and coastal sites - without additional protective enclosures. - **AFCI 2.0 + Smart IV Curve Diagnosis** - The built-in AFCI 2.0 arc-fault circuit interruption function significantly reduces the risk of fire in PV systems - a critical feature for commercial facilities operating 24/7. Smart IV Curve Diagnosis enables remote scanning of string I-V characteristics without additional test equipment, shortening fault identification time and reducing the need for on-site service visits. - **Integrated PID Recovery Module** - The Potential Induced Degradation (PID) compensation function is built directly into the inverter, eliminating the need to purchase a standalone PID recovery unit (~€120-300 per unit). It protects modules against potential-induced degradation, which is particularly important for bifacial modules and large systems operating at DC voltages up to 1,100 V. - **Fuse-Free Smart String Current Monitoring** - The fuse-free design with Smart String Current Monitoring eliminates the cost and failure risk associated with DC string fuses, while enabling remote detection of underperforming or faulty strings via iSolarCloud - without requiring a physical service visit, thereby reducing ongoing O&M costs for commercial installations. ### Cons - **Wi-Fi Not Included as Standard** - Wireless Wi-Fi connectivity requires the purchase of a separate dongle (EyeM4 or equivalent) and is not factory-integrated. In commercial installations with a dedicated Ethernet connection this is not critical, but it does add to the typical deployment cost and introduces an additional configuration step during commissioning. ## About this series The Sungrow SG110CX-P2 series are three-phase grid-tie inverters designed for large commercial and industrial installations, where stable operation and fast service are paramount. They feature **multi-point MPPT tracking**, which simplifies string design on rooftops with varying orientations and slopes, and minimizes losses during partial shading - each PV segment can operate closer to its own maximum potential. In practice, this translates to more predictable annual energy yields. A major advantage is their **high European efficiency**, which better reflects actual energy production under typical operating conditions in Poland than maximum efficiency alone. The inverters also offer **advanced monitoring and diagnostics** via iSolarCloud, enabling remote configuration, firmware updates, and parameter monitoring. Communication can be achieved via RS485, and optionally via WiFi or Ethernet. This solution is tailored for investors seeking **security and environmental resilience** (surge protection, safety features, outdoor-rated enclosure), as well as compliance with connection requirements and clear warranty terms. ## Questions ### How many MPPT inputs does the Sungrow SG110CX-P2 inverter have, and what does that mean for my installation? The SG110CX-P2 is equipped with 12 independent MPPT inputs (9 tracking units, each supporting 2 strings). This allows PV panels to be connected across multiple orientations or tilt angles without significant energy losses. In practice, for a commercial installation on a large flat or multi-pitch roof, each section of the array operates closer to its maximum power point, resulting in higher annual energy yield. ### What warranty does the Sungrow SG110CX-P2 inverter come with? The standard manufacturer's warranty for the SG110CX-P2 series is 10 years. Sungrow also offers a paid warranty extension up to 15 years, which is worth considering for high-capacity commercial installations given the potential replacement cost of the unit. Sungrow holds Tier 1 manufacturer certification, which further reflects the reliability of their after-sales support. ### Is the Sungrow SG110CX-P2 suitable for outdoor installation? Yes, the SG110CX-P2 carries an IP66 protection rating, meaning it is fully protected against dust ingress and powerful water jets. In addition, its C5 anti-corrosion certification allows installation in environments with elevated levels of dust or humidity, such as industrial zones or coastal areas. The unit can therefore operate outdoors without the need for a separate protective enclosure. ### Which monitoring platforms is the Sungrow SG110CX-P2 compatible with? The SG110CX-P2 integrates with the iSolarCloud platform, enabling remote monitoring of operating parameters, diagnostics, configuration, and firmware updates. Communication is handled via RS485 as standard; an optional Wi-Fi or Ethernet module can also be added. For commercial installations, the platform supports simultaneous monitoring of multiple inverters and allows generation of production reports for investors or facility managers. ### What is the maximum PV array power that can be connected to the Sungrow SG110CX-P2? The SG110CX-P2 supports a DC input voltage of up to 1100 V and is compatible with PV modules rated at 500 W and above. The maximum DC-side power exceeds the nominal AC output of 110 kW, allowing for array oversizing that is common in commercial installations. When designing string configurations, the current and voltage limits specified in the manufacturer's datasheet must be strictly observed. ### How does the Sungrow SG110CX-P2 differ from the older SG110CX model? The P2 series is an enhanced version of the SG110CX, introducing several improvements including AFCI 2.0 (arc-fault circuit interruption for enhanced installation safety), an upgraded DC Type I+II and AC Type II surge protection system, and expanded smart IV curve diagnostics. The P2 model is better aligned with the requirements of current grid-connection standards and offers a higher level of protection for commercial and industrial PV installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/ds-20250508-sg110cx-p2-cn-v3-cn-1c8e266764c7.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 | +1 MPPT, 9.0 kg heavier | | [Solis-110K-HV-5G](https://comparepv.com/inverter/ginlong-solis-solis-110k-hv-5g) | 110 kW | 98.5% | 9 | 82.0 kg | Similar on paper | | [Growatt MAX 110KTL3-X LV](https://comparepv.com/inverter/growatt-max-110ktl3-x-lv) | 110 kW | 98.4% | 10 | 84.0 kg | +1 MPPT, 2.0 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 | +3 MPPT, 11.5 kg heavier | | [SOFAR 125KTLX-G4](https://comparepv.com/inverter/sofar-solar-sofar-125ktlx-g4) | 110 kW | 98.3% | 10 | 75.0 kg | +1 MPPT, 7.0 kg lighter | | [Ginlong Solis S6-GC110K](https://comparepv.com/inverter/ginlong-solis-s6-gc110k) | 110 kW | 98.3% | 10 | 96.0 kg | +1 MPPT, 14.0 kg heavier | | [Deye SUN-110K-G03](https://comparepv.com/inverter/deye-sun-110k-g03) | 110 kW | 98.3% | | 81.0 kg | 1.0 kg lighter | | [Growatt MAX 110KTL3-X2 LV](https://comparepv.com/inverter/growatt-max-110ktl3-x2-lv) | 110 kW | | 8 | 84.0 kg | -1 MPPT, 2.0 kg heavier | --- Source: https://comparepv.com/inverter/sungrow-sg110cx-p2-cn
