Step 10: Size the Inverter Before Choosing the Brand
The inverter stage asks the customer to select a capacity range first.
This includes 3 to 3.6 kW small hybrid, 5 kW home hybrid, 6 to 6.5 kW hot-selling hybrid, 8 kW strong home hybrid, 10 to 11.2 kW large home, 12 kW three-phase hybrid, 15 to 30 kW commercial hybrid, 50 kW commercial ESS, or Zorays Solar to size.
This structure is important because brand preference should not come before capacity and use-case.
An inverter is not just a box on the wall. It defines phase compatibility, solar input limits, battery compatibility, backup behavior, monitoring, grid interaction, IP rating, supportability, and future upgrade path.
A 5 kW home hybrid, 12 kW three-phase hybrid, and 50 kW commercial ESS inverter are not different sizes of the same decision. They are different design categories.
Step 11: Use Inverter Brand Cognition, Not Blind Brand Worship
Once capacity is understood, the form asks for inverter brand cognition.
The options may include KSTAR ESS as CEO preferred, Huawei hybrid premium, Knox or Photon as employee choice, GoodWe/Growatt/Solis as customer popular, EASUN/Hwoo as best current rate, FOX as premium warranty, or Zorays Solar to choose.
This is a useful commercial filter.
Some customers buy confidence. Some buy warranty. Some buy current rate. Some buy ecosystem. Some buy recommendation. The form allows that preference to appear without making the entire design dependent on it.
Brand matters. But compatibility, after-sales support, protection design, and installation quality matter too.
