Solar and battery interconnection application
How do we process a solar and battery interconnection application from the installer with the diagrams and approvals chased, engineering's review decided inside the rules' timelines, and permission to operate written to billing?
Run the interconnection on the commission's timelines with the installer doing the chasing from a checklist. Callvu prefills the customer and the premise (the account, the meter, the service size, the transformer and the circuit), takes the installer's application (the system size and type, the inverter and battery models and their certifications, the one-line diagram, the site plan, the export setting), classifies the review track under the interconnection rules by size and screens (simplified, fast track, or study), chases the missing items from the installer and the permits and the final inspection from the municipality on the rules' clocks, routes the engineering review to the interconnection engineer in the Decision Desk with the screens' results, generates the interconnection agreement for signature, and writes the permission to operate with the net metering enrollment to CIS and the billing system.

The problem today
The customer's system sat installed and switched off for nine weeks waiting for a permission to operate that was held up by a one-line diagram with the wrong inverter model.
Interconnection is where distributed energy meets the utility's engineering and the commission's rules. The installer submits an application through a portal or a PDF; the utility's engineer finds the diagram does not match the equipment list; the request for correction goes to an installer who has moved to the next roof; the commission's timeline is missed; the customer, who has paid for a system, calls the commission.
The state's interconnection rules set the application contents, the review tracks by system size with their screens, the timelines for completeness review, engineering review and permission to operate, the standards the equipment must meet, the agreement, and the inspection and witness test requirements. The installer holds most of the documents; the municipality holds the permit and the inspection; the engineer decides on the screens. Each is a chase or a decision with a clock.
An application that is complete on the rules' checklist before the engineer sees it is a permission to operate on time.
How it runs
From the requestto the system of record.
An installer (or a customer) submits an interconnection application for a solar, battery or combined system. Callvu opens the application on the premise.
- Installer
- Submits the application and the diagrams, corrects what is missing, schedules the inspection and signs on the customer's behalf where authorized.
- Customer
- Signs the interconnection agreement and the net metering enrollment on a secure screen.
- Interconnection engineer
- Reviews and decides in the Decision Desk with the screens.
- Municipality
- Issues the permit and the final inspection.
- Callvu
- Prefills, classifies the track, chases, routes, generates the agreement and writes.
Prefill and apply
The customer's account, the premise, the meter, the service size, the transformer and the circuit are prefilled; the installer's application captures the system (the DC and AC size, the inverter and the battery models with their certification listings, the export or non-export setting, the one-line diagram, the site plan, the installer's license) and the customer's authorization.
Classify the track, chase and verify
The system size, the technology and the circuit data classify the review track under the interconnection rules (the simplified or fast track with its screens, or a supplemental review or a study) and set the timelines; the completeness review lists the missing or inconsistent items (a diagram that does not match the equipment, a missing certification, an unlicensed installer) and chases the installer through a link on the rules' completeness clock; the permit and the final inspection are chased from the municipality on the construction clock.
Decide
The interconnection engineer reviews in the Decision Desk with the application, the screens' results (the circuit's penetration, the transformer loading, the export limits, the protection requirements) and only the allowed outcomes within the rules' review period: approve to construct, approve with conditions (an export limit, a protection setting, a meter change), require a supplemental review or a study with the cost estimate, or deny with the reasons; the interconnection agreement is generated and signed by the customer and the installer.
Inspect, write back and enroll
After construction, the final inspection and any witness test are received and matched, the permission to operate is issued within the rules' period, the system and its settings are written to CIS and the billing system with the meter change ordered where needed, and the net metering enrollment runs from the record so the first bill carries the credits.
Where it ends: The application was complete on the rules' checklist, reviewed and decided on the screens within the timelines, agreed, inspected and given permission to operate, with CIS and the billing system holding the system and the net metering enrollment. The Decision Trace shows the track, the screens and the decision; the Audit Trace shows each chase, the signatures, the inspection and the permission with time.
Runtime enforcement
What is enforcedwhile the work runs.
The regulations preloaded in Callvu Studio and the bank's own policies, applied as steps that run, not lines in a binder. A step that breaks a rule does not run, so a completed run was compliant.
The handoff
Between the front doorand the back office.
The front door
The installer's portal or link; the customer signs on a secure screen; the municipality through its channel.
The back office
The interconnection engineer reviews complete applications with the screens; the desk stops relaying corrections.
The Decision Desk
- Every application goes to the interconnection engineer in the Decision Desk with the screens and only approve, approve with conditions, require a supplemental review or a study with the cost, or deny with reasons.

Questions
What buyers ask next,answered plainly.
What does the installer submit?
The system size and type, the inverter and battery models with their certifications, the export setting, the one-line diagram, the site plan, their license and the customer's authorization; the completeness checklist tells them exactly what is missing.
How long does the review take?
The rules' timelines for the track: a completeness notice, a review decision and a permission to operate each within the rules' period, all on the application's clock.
When does net metering start?
On permission to operate, with the enrollment written to CIS and the billing system so the first bill carries the credits.
