Hybrid proposal readiness
Customer inputElectrical Inputs
The connection and consumption data needed to size grid interaction and backup safely.
The latest bill and site electrical details establish the consumer category, sanctioned load, phase type, meter information and consumption pattern. Hybrid design also needs details of existing UPS, inverter, generator or solar equipment.

Why It Matters
How this information affects design, approval, cost and project reliability.
- Sanctioned load and phase type influence inverter selection and utility feasibility.
- Billing history helps separate daytime savings potential from backup requirements.
- Existing backup equipment can affect wiring, changeover, neutral and load-segregation design.
- Meter and service details are needed before export or net-metering assumptions are made.
Complete Checklist
Everything that should be collected or confirmed for this readiness topic.
- Latest complete electricity bill with consumer number, tariff category and sanctioned load visible.
- Up to 12 months of bills where seasonal consumption changes materially.
- Single-phase or three-phase service confirmation.
- Main incomer, meter and existing distribution-board photographs.
- Existing inverter, UPS, battery or generator make, model and capacity.
- Existing rooftop solar capacity, inverter details and approval status if present.
- Known voltage fluctuation, outage frequency or low-voltage concerns.
- Planned new loads such as air-conditioning, pumps, EV charging or commercial equipment.
Verification Process
The practical sequence used to review and confirm the information.
- Read consumer category, sanctioned load, billing units and meter details from the bill.
- Compare bill data with the physical phase and main distribution arrangement during survey.
- Identify existing backup and changeover circuits.
- Record available panel space and the condition of main electrical equipment.
- Flag any connection upgrade or utility clarification needed before final design.
Common Issues to Avoid
Frequent gaps that cause redesign, delay, rejection or unrealistic expectations.
- Only the payable amount is shared while consumption units and tariff details are hidden.
- One bill is treated as representative despite strong seasonal variation.
- The property has three-phase supply but critical loads are concentrated on one phase.
- Existing UPS or generator wiring is undocumented.
- Future high-power loads are omitted from the proposal inputs.
Records Produced
The documents or outputs that should remain in the final project file.
- Electricity-bill and consumption summary.
- Connection and phase record.
- Existing electrical-system inventory.
- Preliminary inverter and meter compatibility note.
- Electrical survey action list.
Ready When
The completion conditions that allow the proposal to move forward confidently.
- The current bill is legible and belongs to the proposed site.
- Phase type, sanctioned load and tariff category are known.
- Existing inverter, UPS, generator and solar equipment are recorded.
- Main meter and DB arrangement can be verified during survey.
- Known future loads and connection changes are documented.
Important planning note
Monthly bill value alone is not enough for hybrid sizing; units consumed, load timing, outage behavior and electrical connection details must be reviewed together.
