An AI sales agent's commercial inverter order, checked before it goes out

An AI sales agent prepares an order for a SolarEdge three-phase commercial inverter (USA Domestic Content Eligible, SE10KUS to SE40KUS) for a fictional commercial rooftop solar installer: the model, the grid voltage at the site, the DC array and its voltage and current, the wiring and any domestic content requirement. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public SolarEdge datasheet says and returns a verdict, every reason and the figures it computed. The customer is fictional.

Scope: SolarEdge SE10KUS, SE17.3KUS, SE30KUS and SE40KUS three-phase commercial inverters only: grid, DC array, voltage, current, wiring, site, noise, power factor and options. See everything this validator covers

This validator models orders for the SolarEdge three-phase commercial inverters SE10KUS, SE17.3KUS, SE30KUS and SE40KUS (USA Domestic Content Eligible), based on the public datasheet DS-000246-NAM of January 2025, not just the scenarios shown below.

  • Grid — the line-to-line voltage range of each model (183 to 229 V for the SE10KUS and SE17.3KUS, 422.5 to 529 V for the SE30KUS and SE40KUS) and a 60 Hz grid; the power factor range of 0.85 to 1.
  • DC array — maximum DC power, operating voltage range, maximum input current, maximum short circuit current of 55 A and 3 fuseless DC input pairs.
  • AC output and statement — the AC power the project needs against the rated output, and the rated output the order states against the datasheet.
  • Wiring and site — AC wire 6 to 10 AWG, DC wire 6 to 12 AWG, an operating range of -40 to 140 F and a noise level below 62 dBA against the site limit.
  • Options — domestic content eligibility (only with certain SolarEdge USA-manufactured power optimizers; a person confirms the pairing and the tax treatment) and the built-in rapid shutdown, listed when paired with the C651U.

Any order of these four inverters that touches these rules is in scope — not only the scenarios pictured here. Not covered: power optimizer string sizing (the datasheet refers to a separate technical note), temperature derating, other SolarEdge inverters, prices (SolarEdge does not publish them), delivery and installation.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Limits that differ by modelOnly with care
The voltage class, DC power, operating voltage and input current all differ between the four models. A rules-based CPQ can store the table, but it has to be kept in step and compared with each design.		The model is read together with the grid and the DC design, and every limit is computed on every call.
Options that depend on a pairingOnly with care
Domestic content eligibility depends on pairing the inverter with certain USA-manufactured optimizers. Each is a product rule that has to be written and maintained.		The pairing is checked together with the requirement on every call.
The figure the order statesOnly with care
The rated output stated in the order is a free-entry field; a rule has to look up the right table row and compare.		The stated figure is a field in the request, compared with the datasheet figure for the model on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a SolarEdge three-phase commercial inverter (USA Domestic Content Eligible, SE10KUS to SE40KUS) for a fictional commercial rooftop solar installer: the model, the grid voltage at the site, the DC array and its voltage and current, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public SolarEdge datasheet says and returns a verdict, every reason and the figures it computed. The customer is fictional.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a SolarEdge SE30KUS for a 208 V site at 60 Hz. The project needs 15,000 W of AC output, with a 24,000 W DC array at a design of 450 V. The rest of the request is on screen. The quote states a rated output of 30,000 W.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The site voltage is 208.0 V line to line; the datasheet gives 422.5 to 529.0 V for this model. The design DC voltage is 450 V; the datasheet gives an operating range of 840 to 1000 V for this model. The design DC current is 40.0 A; the datasheet gives a maximum input current of 36.25 A for this model.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for limits that differ by model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to SE17.3KUS and the stated rated output to 17,300.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
