Predictika · Hybrid inverter and battery orders

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

An AI sales agent prepares an order for a Symo GEN24 Plus hybrid inverter with a battery family, a battery size, a number of batteries, a solar generator size and a stated total storage. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the compatibility and technical data Fronius publishes and returns a verdict, every reason and the figures it computed.

Scope: Fronius Symo GEN24 Plus 6.0, 8.0 and 10.0 hybrid inverters with Fronius Reserva Pro, Fronius Reserva, BYD Battery-Box Premium HVS and HVM batteries: size, batteries in parallel, solar generator size and stated storage. See everything this validator covers

This validator models orders that pair a Symo GEN24 Plus 6.0, 8.0 or 10.0 with a battery, not just the scenarios shown below.

  • Battery sizes — each battery family is listed with particular sizes for the Symo GEN24 Plus (for example BYD HVS in 5.1, 7.7, 10.2 and 12.8 kWh, and BYD HVM in 11.0 to 22.1 kWh; the 8.3 kWh HVM is not listed for it); a size that is not listed is blocked.
  • Batteries in parallel — up to 4 Reserva Pro or Reserva, up to 3 BYD HVS, and up to 3 BYD HVM, except the 22.1 kWh HVM, where up to 2 can run in parallel on one inverter.
  • Solar generator — the maximum PV generator power of the inverter: 9 kWpeak for the 6.0, 12 kWpeak for the 8.0 and 15 kWpeak for the 10.0.
  • Stated storage — the total storage the order states is compared with the battery size times the number of batteries. Reserva Pro in 24, 28 and 32 kWh is flagged for a person to confirm with Fronius, because the Fronius table notes country-specific certification and availability and the readings of that table were not consistent.

Any Symo GEN24 Plus 6.0 to 10.0 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Fronius does not publish list prices for these products, so this validator produces no price build-up or line-item quote), the Primo GEN24 Plus, the SC variants, the 3.0 to 5.0 sizes, Symo Hybrid and Verto Plus, the LG Flex and the BYD HVS+ and HVM+ batteries, backup power options, and installation. The model reflects the Fronius pages read in October 2026.

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 battery size that is listed for some inverters and not othersOnly with care
Each battery family and size has its own set of compatible inverters, so each pairing needs its own rule, and the lists have to be kept in step with the published table.		The inverter, the battery family and the size are in one request and checked together on every call.
A limit on batteries in parallel that depends on the battery sizeOnly with workarounds
The limit changes for one size of one family (the 22.1 kWh HVM allows 2 where its smaller sizes allow 3), so it needs a special rule on top of the family rule.		The number of batteries is compared with the limit for the exact family and size on every call.
A stated total storage that disagrees with the battery size and countOnly with workarounds
The total is a derived figure; checking a stated total against it takes extra formulas that interact with the rest of the rules.		The stated total is a field in the request and is compared with the computed one.
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.

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 Symo GEN24 Plus hybrid inverter with a battery family, a battery size. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the compatibility and technical data Fronius publishes and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Fronius Symo GEN24 6.0 Plus with 2 BYD Battery-Box Premium HVM 8.3 kWh batteries in parallel and a 10.5 kW solar generator. The order states a total storage of 16.6 kWh. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. A battery size of 8.3 kWh is not listed as compatible with the Symo GEN24 Plus for the selected battery family. The quote has 10.5 kW of solar generator power; the selected inverter allows at most 9 kW.
    6. 
      
  6. The validator returned two 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 a battery size that is listed for some inverters and not others, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the battery size to 22.1 kWh, the number of batteries to 3, the solar generator to 9 kW and the stated total storage as to 66.3 kWh.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The quote has 3 batteries; between 1 and 2 can be operated in parallel on one inverter with this battery.
    12. 
      
  12. Two findings cleared, but the change brings a different blocking finding: too many batteries in parallel.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the battery size to 19.3 kWh and the stated total storage as to 57.9 kWh.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Two 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.
