Solis 15kW & 20kW On-Grid Solar Inverter | The Compact Powerhouse for Commercial & Agricultural Solar Systems

For project developers, EPCs, and business owners, the right inverter directly impacts your Levelized Cost of Energy (LCOE) and long-term operational headaches. Here’s how the Solis 15-20kW inverter makes the decisive difference:

Optimized for Higher Yield & Faster Payback: Features a >150% DC/AC oversizing ratio. This allows you to install more solar panels (DC capacity) than the inverter's rated AC output, capturing significantly more energy during peak sun hours and shoulder seasons, dramatically increasing your annual energy production and accelerating your return on investment.

Built to Endure, Engineered to Protect: With a robust IP66 ingress protection rating and C5 anti-corrosion coating, this inverter is built for challenging environments. It reliably operates in temperatures from -25°C to 60°C, resisting dust, moisture, and corrosive elements common in agricultural, coastal, or industrial settings. An integrated DC switch and comprehensive protection suite ensure safety and simplify installation.

Unmatched Design Flexibility: Equipped with 2 independent Maximum Power Point Trackers (MPPTs), it can efficiently manage solar arrays with different orientations, tilts, or module types on a single inverter. This eliminates power losses from string mismatch, making it the ideal choice for complex rooftops or projects with partial shading.

Smart Management, Proactive O&M: Go beyond basic monitoring. The integrated I-V Curve Scanning feature allows for remote, precise diagnosis of your PV array. Quickly pinpoint issues like module degradation, string faults, or shading without costly site visits. Combined with 24/7 load monitoring via the user-friendly Solis Cloud platform and mobile app, you maintain full control and minimize downtime.

1. What is the main benefit of the >150% DC/AC oversizing capability?
This feature allows you to install a larger solar array (DC capacity) relative to the inverter’s rated AC output. It maximizes energy capture during peak sunlight hours and in low-light conditions, significantly increasing your system’s total annual energy production and accelerating your return on investment.

2. How does the 2-MPPT design help in real-world installations?
With two independent Maximum Power Point Trackers (MPPTs), the inverter can efficiently manage solar panels installed on different roof planes, with varying orientations or tilt angles. This prevents energy loss from mismatched strings, making it an ideal and flexible solution for complex commercial or agricultural rooftops.

3. Is this inverter suitable for harsh environments like farms or coastal areas?
Absolutely. Its IP66 rating ensures complete protection against dust and powerful water jets, while the C5 anti-corrosion coating defends against corrosive atmospheres (e.g., from fertilizers, salt spray). Combined with a wide operating temperature range (-25°C to 60°C), it is built for long-term reliability in demanding locations.

4. Can I monitor and troubleshoot the system remotely?
Yes. The inverter connects to the Solis Cloud monitoring platform via 4G/Wi-Fi. Its advanced I-V Curve Scanning function allows for remote diagnosis of the PV array, helping to quickly identify issues like module faults, shading, or wiring problems without an immediate site visit, reducing operational costs.

5. Does it provide backup power during a blackout?
No, this is a standard grid-tied inverter. For safety and compliance, it will automatically shut down during a grid outage (anti-islanding protection). If backup power is required, please inquire about our hybrid inverter and battery storage systems, which are designed to provide energy independence and off-grid capability.
