Does the output match the inverters?

The output appears nowhere as a number. Ziva computes it per zone and checks it against the inverters.

In the screenshot

  1. Output per panel type
  2. Zone A: 13.78 kWp on a 15 kW inverter
  3. DC to AC ratio per zone
The “Puissance” sheet in Ziva: installed output per zone computed from the quantities, with the inverters and the DC to AC ratio.

A named product, and the equivalence proof is on you

Ziva lists every product-bound item with its properties. You enter your model; the table computes the gap.

In the screenshot

  1. The named product
  2. The property to match
  3. Your model and the gap
The “Équivalences” sheet in Ziva: product-bound items with the named product, the required property and fields for your model.

Who supplies, who connects, who certifies?

It sits in item texts, not lists. Ziva compiles who does what, each with its page.

In the screenshot

  1. The electrician connects to the main board
  2. Kit “similar to” a named product
  3. Module values as the benchmark
