The choice depends on the size of your solar panel array. This 3.4KW inverter supports a higher maximum DC input of 4.08kW compared to 3.6kW on the 3KW model, while also handling higher AC output current. If you're planning to install a solar array in the 3.4–4kW range, this model allows you to utilize more of your system's output and helps avoid power clipping without any additional investment.
Yes. With a weight of only 4.5 kg, the inverter is compact and suitable for installation on most standard masonry or concrete walls using the supplied mounting bracket. However, if the inverter is being installed on a hollow, lightweight, or non-standard wall, your installer should verify that the mounting surface can safely support the unit.
Yes. The inverter features an MPPT operating range starting at 70V, allowing it to begin tracking and converting solar energy even under lower light conditions. This helps extend the daily generation window by producing usable power earlier in the morning and later in the evening compared to systems that require a higher start-up voltage.
The inverter is designed to operate in temperatures ranging from -25°C to +60°C and uses natural convection cooling, eliminating the need for cooling fans. While this makes the inverter quieter and more reliable, it is still recommended to install it in a well-ventilated location and avoid fully enclosed spaces to ensure optimal thermal performance and long-term reliability.
This inverter complies with several internationally recognized safety and performance standards, including BIS certification, IEC 62109 for electrical safety, IEC 61727 and IEC 62116 for grid-interconnection performance, and IEC 61000 for electromagnetic compatibility. These independent certifications verify that the inverter meets established industry requirements for safety, reliability, and grid operation.
Yes. The inverter comes with a 10-year (120-month) warranty, and maintaining warranty coverage generally requires installation by a qualified professional in accordance with the manufacturer's guidelines. For complete warranty registration and installation requirements, it is advisable to confirm the applicable terms with your authorized Okaya dealer at the time of purchase.
