Predictika · Solar combiner box orders

An AI sales agent's solar combiner order, checked before it goes out

An AI sales agent prepares an order for a 1500 V high-current combiner box, with a model variant, a number of input circuits, an output rating, output conductors, fuse size and site conditions. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the datasheet rules and returns a verdict, every reason and the figures it computed.

Scope: Shoals 1500V High Current Combiner orders (variants AC, AP and AO): input circuits, output rating, output conductors, fuse size, voltage and ambient temperature. See everything this validator covers

This validator models orders for the 1500V High Current Combiner in the public Shoals datasheet, not just the scenarios shown below.

  • Model limits — each variant takes a different number of input circuits (up to 12 on the AC and AP, up to 14 on the AO), offers different rated output currents (AC 400 or 500 A, AP 400 A, AO 400, 500 or 600 A) and accepts different output conductor sizes for one or two conductors per pole.
  • Ratings — input fuse size against the 65 A maximum overcurrent protection, system voltage against the 1500 VDC maximum and ambient temperature against the 50 degrees C rating.
  • Stated figures — an enclosure height stated on the order is compared with the datasheet height for the selected variant (24, 36 or 30 inches).

Any order for this combiner that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Shoals publishes no list prices for these combiners, so this validator produces no price build-up or line-item quote), other Shoals products such as the Big Lead Assembly, recombiners and harnesses, the choice of disconnect, enclosure and surge protection brands (no compatibility rules found), fuse sizing for a particular project (the datasheet says it needs project information), and the datasheet variants for other standards.

The AI sales agentBuilds the combiner order from the conversation and says it is ready.

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
A rated output current that differs by variantOnly with care
Each variant has its own list of offered ratings, so each needs its own compatibility rule, and a new variant adds more rules to maintain.
The variant and the rating are in one request and compared on every call.
An output conductor limit that depends on the variant and on one or two conductors per poleOnly with workarounds
The maximum depends on two other choices, so it takes a lookup that must be kept in step with the datasheet.
The variant, the conductor count and the size are in one request and the limit is worked out and compared on every call.
A stated enclosure height that disagrees with the datasheetOnly with workarounds
The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the value the variant implies.
The stated figure is part of the request and is compared with the datasheet value on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.
All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

Narration transcript

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 1500 V high-current combiner box, with a model variant, a number of input circuits. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the datasheet rules and returns a verdict, every reason and the figures it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote a Shoals 1500V High Current Combiner, model variant AC, with 12 input circuits, a rated output current of 600 A and input fuses of 70 A. The quote states an enclosure height of 24 inches. The rest of the request is on screen.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with five findings, all in one answer. The rated output current of 600 A is not offered on the selected model (AC: 400 or 500 A; AP: 400 A; AO: 400, 500 or 600 A). The output conductor size of 900 MCM is above the 800 MCM the selected model accepts for that number of conductors per pole. The input fuse size of 70 A is above the 65 A maximum overcurrent protection in the datasheet. The other two are on screen.
  6. The validator returned five 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. What this shows: for an output conductor limit that depends on the variant and on one or two conductors per pole, a rules-based CPQ can do this only with workarounds.
  8. Now the agent resubmits.
  9. The corrected request. It changes the rated output current to 500 A, the input fuse size to 60 A and the system voltage to 1,500 VDC.
  10. It calls the validator again.
  11. Still blocked, with two findings, all in one answer. The output conductor size of 900 MCM is above the 800 MCM the selected model accepts for that number of conductors per pole. The ambient temperature of 55 degrees C is above the 50 degrees C maximum rating.
  12. Three findings cleared. Still blocking: output conductor larger than the model accepts and ambient temperature above the rating.
  13. The agent resubmits once more.
  14. The revised request. It changes the output conductors per pole to 2, the output conductor size to 700 MCM and the ambient temperature to 45 degrees C.
  15. It calls the validator once more.
  16. This time the validator clears it.
  17. Both earlier findings are cleared, and the validator's figure matches the quote.
  18. Five problems caught in one call, fixed in two passes, 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.
