Predictika · Enphase IQ system quotes

An AI sales agent's solar and battery quote, checked before it goes out

An AI sales agent prepares a system quote for Enphase IQ8-series microinverters with IQ Battery storage: microinverter model, branch circuits, modules, service voltage, panel, combiner, batteries and backup. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the compatibility and sizing rules, compares the capacity figures the quote states with the computed ones, and returns every finding together. This is an illustrative model built from public data sheets; it has no prices and is not Enphase's internal rule set.

Scope: system quotes for Enphase IQ8-series microinverters (IQ8, IQ8+, IQ8M, IQ8A, IQ8H-240, IQ8H-208) with IQ Battery 5P and 10T, an IQ Combiner 5C and an IQ System Controller 3. See everything this validator covers

This validator models one product line: Enphase's IQ8-series microinverters with the IQ Battery 5P and 10T, the IQ Combiner 5C and the IQ System Controller 3, as quoted by an installer or distributor. It handles any quote involving these products, not only the scenarios shown on this page.

  • Covered: microinverters and modules — the service voltage each model is built for, microinverters per 20 A branch circuit, and the module's open-circuit voltage, short-circuit current and wattage against the model.
  • Covered: combiner and panel — solar and battery circuits against the four breaker spaces of one combiner, and a simplified form of the 120 percent busbar rule with the main breaker.
  • Covered: batteries and backup — the system controller needed for backup, backup on 208 V service, and the backup load and hours against the battery power and energy quoted.
  • Covered: stated figures — the AC capacity, array size and battery capacity the agent states against the computed ones.
  • Not covered — prices (no public installer or distributor price list was used, so this page produces no line-item quote and no price build-up), other Enphase products and models, production estimates, permits, and local utility or code rules.
  • Labeled as assumptions — limits come from Enphase's public data sheets as read on October 4, 2026 and are simplified; the four combiner breaker spaces, a 20 A breaker per battery and the IQ Battery 10T on 208 V (not confirmed in those documents, so it goes to approval) are modeling choices. The module in each scenario is a generic 410 W module, not an Enphase product.

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
Microinverters per branch circuit, which differs by modelOnly with care
The limit per 20 A circuit is 16 for one model and 9 for another. A rule per model can check it, but every new model is another rule to keep in step with the data sheets.		The limit sits on each microinverter record; the circuit count is compared on every call and the finding states both numbers.
Service voltage that decides which models are allowedOnly with care
Most models are for 240 V split-phase service and one is for 208 V. A product rule can filter the list once the voltage is chosen, but the voltage is often entered later or on another screen.		The service voltage travels with the request and is checked against the chosen model on every call.
The 120 percent busbar rule across solar breakers, battery breakers and the mainOnly with workarounds
The rule adds breakers from several lines and the main breaker and compares the sum with a busbar rating. Expressing it in a rules-based CPQ usually takes custom code or a formula field that a person must keep updated.		The breakers are computed from the circuits and batteries quoted and compared with the busbar and main on every call.
Backup sized against the load and hours wantedOnly with workarounds
Battery energy and power are multiplied by the count, then compared with a load and a duration that are not product attributes. Rules rarely carry that customer data.		Load and hours travel with the request; energy and power are compared with the batteries quoted, and each shortfall is its own finding.
Stated capacity figures that must match the computed onesOnly with workarounds
A validation rule can compare a stated figure with a calculated one only if the stated figure is a field on the quote, which it rarely is.		The stated AC capacity, array size and battery capacity travel with the quote and are compared with the computed values on every call.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
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.

    
117 IQ8 microinverters exceed the branch circuit limit: 16 per 20 A circuit, 16 in total with 1 circuit(s) quoted.
2A 450 W module is outside the 235 to 440 W pairing range listed for the IQ8+; confirm it in the Enphase module compatibility tool.
3Backing up 7.0 kW for 2.5 hours needs 17.5 kWh but the quote has 10.0 kWh of battery capacity.
4Backup is requested but the quote has no battery.
5Backup needs an IQ System Controller 3 in the quote.
6Breakers of 80 A for solar and storage plus the 161 A main exceed 120 percent of the 200 A busbar.
7IQ Battery 10T on 208 V service is not confirmed in the public documents the model was built from; confirm with the manufacturer.
8IQ8H-208 is built for 208 V service only; this quote is for 240 V service.
9Module open-circuit voltage of 55.0 V is above the IQ8 maximum DC input of 50 V.
10Module short-circuit current of 21.0 A is above the 20 A maximum module current.
11Solar branch circuits (3) plus battery circuits (2) need more than the 4 breaker spaces in one IQ Combiner 5C.
12Stated AC capacity does not match: the agent stated 7.5 kVA; the validator computes 6.5 kVA.
13Stated array size does not match: the agent stated 9.0 kW; the validator computes 8.2 kW.
14Stated battery capacity does not match: the agent stated 20.16 kWh; the validator computes 10.0 kWh.
15The 4.0 kW backup load is above the 3.84 kVA of battery power quoted.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a system quote for Enphase IQ8-series microinverters with IQ Battery storage: microinverter model, branch circuits, modules, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the compatibility and sizing rules, compares the capacity figures the quote states with the computed ones, and returns every finding together. This is an illustrative model built from public data sheets; it has no prices and is not Enphase's internal rule set.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Quote for the Okafor residence on a 240 V service. The quote states 9.75 kVA of AC capacity, a 12.3 kW array and 10.08 kWh of battery capacity. 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. 30 IQ8M microinverters exceed the branch circuit limit: 11 per 20 A circuit, 22 in total with 2 circuit(s) quoted. Breakers of 60 A for solar and storage plus the 200 A main exceed 120 percent of the 200 A busbar.
    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 microinverters per branch circuit, which differs 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 branch circuits to 3 and the main breaker to 150 A.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two 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.
