Products Description
What are advantages of Solis 350KW Commercial Inverter?
1. High-Power Density for Space Efficiency
This inverter is optimally sized and rated at 350 kilowatts, which is a huge advantage over traditional central inverters that generally have a larger footprint (approximately 1,200mm x 800mm x 300mm)-this is important to note due to limited available space on both commercial carports and ground-mounted solar systems. In addition to its increased power density, the modular design allows for the parallel operation of multiple inverters, which results in a reduction in installation costs of approximately 20% when compared to conventional inverter installations, along with simplified maintenance processes associated with the inverter.
2. Advanced Multi-MPPT Technology
Solis has developed a new commercial inverter (350KW-DC Inverter) for optimizing efficiency by providing six independent MPPT channels to accommodate shading and/or mismatches in orientation patterns which can occur often at commercial sites. Each MPPT is rated to accept approximately 30 kW of input power so that no power is lost because of shading/mismatch resulting in up to an 8% increase in energy production on an annual basis as compared to a standard single-MPPT.
3. Grid-Interactive Intelligence
With advanced grid-interfacing capabilities, this inverter is prepared for meeting the needs of modern utility grids, offering the requisite capability to operate under the Low Voltage Ride Through (LVRT) and High Voltage Ride-Through (HVRT) grid codes, as well as supporting a variety of reactive power compensation strategies to increase the stability of the distribution system during both demand and generation fluctuations. The inverter will allow for dynamic output adjustments in relation to changes in frequency and/or voltage on the grid in order to meet international guidelines (the IEEE 1547 standard and VDE-AR-N 4105). For businesses that have storage systems or electric vehicle (EV) chargers, this inverter offers an "EV-ready" feature that allows for the integration of bidirectional EV charging systems into the overall design of their solar energy system, effectively transforming it into a flexible energy center.
4. Ultra-High Conversion Efficiency
The Solis 350KW Commercial Inverter has the highest efficiency rating of 99.2% and CEC-adjusted rating of 98.8%, resulting in the least amount of energy lost through DC-to-AC conversion. Its broad range of maximum power point tracking voltage levels (200V – 1000V) allows for best performance even in very dimly lit situations; this inverter can be powered by natural convection cooling without fans, thus eliminating noise and the need for regular maintenance; this feature is particularly beneficial in urban and noise-sensitive commercial facilities.
5. Industrial-Grade Durability
The inverter indicated is suitable for continuous use outdoors under all weather conditions and will function properly under extreme temperature conditions (from -25C to +60C) due to its enclosure rated IP66 (dustproof and waterproof). An aluminum chassis, built using corrosion-resistant materials, provides added corrosion protection, while the surge protection features built into the inverter provide protection against lightning strikes and electrical surges that can be associated with outdoor applications (up to 20kV).
Applications
This inverter has been specifically tailored for large scale applications that include:
Utility Scale Solar Farms
The parallel performance capability of the inverter allows for the operation of multiple Megawatt systems.
01
Industrial Facilities
Industrial facilities have varying high energy consumption needs, including factories, warehouses and manufacturing plants.
02
Electric Vehicle Charging Facilities
Electric vehicle charging stations generally utilize fast chargers, and the inverter provides access to renewable energy.
03
Microgrids
As the main inverter for off-grid or hybrid systems with energy storage.
04
Commercial Rooftops
The inverter captures energy that would normally go to waste from large retail, office and logistics center rooftops.
05

After-Sales Service
10-Year Complete System Warranty
Covers every component – panels, battery, inverter, and mounting hardware. If anything underperforms due to manufacturing defect, we replace it at no cost, including shipping.
24/7 Remote Monitoring Support
Our support team monitors your system's health proactively. If a connection drops or a battery behaves oddly, we'll contact you before you even notice. Most issues are fixed over the air via the monitoring platform.
Lifetime Technical Helpdesk
Got a question about settings? Want to expand your battery capacity later? Need to reset something after a storm? Call, email, or chat with a real technician – not a bot. No per-incident fees, no "premium support" upsells.
Free Spare Parts Shipping for 5 Years
If a minor component (like a DC breaker or sensor) fails, we ship a replacement overnight at our cost. Your system stays online while you wait.
Free Annual System Check-Up
Every year, we'll remotely test your battery capacity, panel degradation, and safety systems. You'll receive a digital health report with recommendations. Optional on-site inspections available at cost – but usually not needed.
