The Solis 40kW 5G 3 Phase Quad MPPT – DC is a high-performance grid-tied solar inverter well suited for medium-to-large commercial and industrial photovoltaic (PV) installations. Designed to handle challenging solar array configurations and deliver reliable power conversion, this three-phase inverter offers a solid balance of efficiency, flexibility, and advanced protection features for demanding sites such as commercial rooftops, warehouses, and industrial facilities.

At its core, the 40kW model delivers 40 kW of continuous AC output, with short-term peak output of up to approximately 44 kW under optimal conditions — making it capable of balancing significant PV generation with grid needs. Its quad MPPT (Maximum Power Point Tracking) design, with four independent tracking channels, allows installers to group solar strings into four optimised inputs. This means panels with differing orientations, tilts, or partial shading can be configured to maximise energy harvest and reduce mismatch losses.

Efficiency is a highlight of this inverter. It achieves maximum conversion efficiency exceeding 98%, helping ensure more of the DC power generated by solar panels is converted into usable AC electricity with minimal loss. The wide DC input voltage range — with ultra-low startup around 180 V, an MPPT tracking range from about 200 V to 1 000 V, and a maximum DC input voltage of up to 1 100 V — offers design flexibility when configuring longer strings or using high-voltage modules.

Safety and reliability are built into this inverter’s engineering. It includes Type II surge protection on both DC and AC sides to safeguard against transient over-voltages, integrated AFCI (arc-fault circuit interruption) to help reduce risk of fire from DC arc faults, and DC reverse-polarity protection to prevent damage from incorrect connections. Its robust IP66 rated enclosure makes it suitable for outdoor environments exposed to dust and moisture.

Connectivity and smart monitoring features further enhance the user experience. The unit supports remote monitoring and system diagnostics via platforms such as SolisCloud, with options for RS-485, Wi-Fi, or GPRS communication depending on installation setup. This facilitates real-time performance tracking, simplifies maintenance, and helps optimise system uptime over the long term.

Overall, the Solis 40kW 5G 3 Phase Quad MPPT – DC inverter is a reliable and efficient choice for larger grid-connected PV systems. Its combination of multi-MPPT flexibility, high conversion efficiency, rugged design, and smart monitoring capabilities makes it well suited to commercial and industrial renewable energy projects.
