Predictika · SMA Sunny Tripower X Design Validator

Before a solar quote is sent, the array and its connection are checked against the inverter’s published limits

An installer’s quoting agent drafts quotes for commercial rooftop arrays built on SMA Sunny Tripower X inverters. Before a quote goes to the customer, the agent calls Predictika’s validator with the design: inverter model, modules and strings per input, module data, grid connection, protection and cables. The validator checks it against the limits in SMA’s published manual and reports every problem at once.

Scope: design check for SMA Sunny Tripower X inverters STP 12-50, 15-50, 20-50 and 25-50 onlySee everything this validator covers

This validator covers one product line: the three-phase SMA Sunny Tripower X inverters in four sizes, STP 12-50, STP 15-50, STP 20-50 and STP 25-50. It checks the design behind a quote for these inverters:

  • PV array — modules per string, strings per MPP input, array power against the model’s maximum, voltage on the coldest and hottest day, MPP current and short-circuit current, and the MPP voltage range for rated power.
  • Connection — grid type, three-phase connection, residual-current device type and rating, one device per inverter, AC and grounding conductor sizes.
  • Modules and DC side — DC cable size, protection class II, no grounded outputs, module coupling capacity.
  • The agent’s own figures — the array power and string voltage it states must equal what the modules add up to.

It handles any quote involving these four inverters, not just the eight scenarios shown here. It does not cover other SMA products, batteries or energy-management systems, prices, or country-specific grid codes and permits.

What the validator sees: the design in the quote and the agent’s stated figures; no drawings or site dataRead more

The validator receives the choices in the quote, the module datasheet values and the figures the agent states for array power and cold string voltage. It does not see roof layouts, shading or local requirements. If the datasheet values entered are wrong, the answer follows.

The AI agentDrafts the quote, states the array power and string voltage, then calls the validator before releasing it.

Every finding the validator returned across all 53 test runs, with the wording it used. Each finding is reported and none stops the others, so one violation can never hide another. A block means the agent must not do this; a review means a person must sign off first.
