Why We Recommend the NKF Inverter
We recommend the NKF for buyers who need a choice of power ratings and AC configurations—not a one-size-fits-all inverter. The range covers 3–10 kW, with single-phase/split-phase input options and adjustable output voltage and frequency. This gives you a practical starting point for matching the model to your customers’ power requirements and local AC supply, rather than selecting by wattage alone.
Intelligent air cooling, protection and alarm functions complement that flexibility. To turn your requirements into a clear purchasing decision, share your required power, AC arrangement, PV and battery configuration, and order quantity with SNADI. We’ll help confirm the appropriate NKF model and prepare a factory quotation, so you can compare a defined configuration—not just a headline price.

FAQS
Which NKF model and AC arrangement should I quote?
The catalog lists NKF-302024, NKF-302048, NKF-402048, NKF-502048, NKF-642048, NKF-802048 and NKF-103048. Confirm the rated power and the required single-phase or split-phase input arrangement for the exact model before ordering.
Which battery and communication details should I confirm?
The catalog lists lead acid, colloidal, lithium iron phosphate, ternary lithium and customized battery options, with WIFI(RS485)/BMS(RS485) dry contact communication. Share the battery type, voltage and required interface so SNADI can check the selected model.
What PV input limits belong in the quotation?
The catalog shows 60A*1, 80A*1 or 120A*1 photovoltaic interfaces, maximum photovoltaic input power of 1440W, 2880W, 3840W or 5760W by model grouping, and a 30V-180V (24V system) or 60V-180V (48V system) input range. Match the PV plan to the exact model column.
Which output and monitoring requirements should I discuss with SNADI?
The catalog documents pure sine wave output, adjustable output voltage and 50Hz/60Hz frequency, plus an under-10ms transfer time and the listed RS485/WIFI interfaces. Include the load, output and monitoring requirements for the factory team to verify.
What information is needed for a factory quotation?
Send the exact NKF model code, target quantities, PV input plan, battery type and voltage, AC input/output arrangement, communication requirement and destination market. SNADI can then confirm the model-specific configuration with the current documents.
