A quick decision brief for this specific tool
Inputs that matter
One named and revisioned completed PV array/inverter nameplate-ratio record; one already-selected exact system and array configuration; aggregate array DC nameplate source, revision, exact row and rating basis; one already-selected exact inverter manufacturer/model/configuration/quantity; total inverter AC nameplate source, revision, exact row and rating basis; arithmetic/conversion method and responsible reviewer; positive array DC and total inverter AC nameplate capacities independently tagged W or kW; optional independent completed same-record DC/AC ratio with its exact source and an optional separate reviewer-owned arithmetic tolerance; plus explicit source-owned array, source-owned inverter, same-system/configuration/basis coherence and arithmetic-only decision boundaries
Output to expect
Normalized array DC and total inverter AC nameplate capacities in W and kW; dimensionless array-DC/total-inverter-AC nameplate ratio; optional reported-minus-reproduced ratio and inside/outside owner-tolerance state; complete system/configuration/source/revision/rating-basis/method/reviewer evidence; deliberate page-session retention, copy/Markdown/print/share actions; and stable Project outputs that keep weather/loss output estimation, assumed/optimized ratio, product/quantity selection, clipping/yield/cost/ROI prediction, string/MPPT electrical/thermal validation, off-grid load/surge/battery/hybrid sizing and certification/interconnection/code/safety/installation approval false
How it works
Validate one coherent completed already-selected system/configuration record; preserve both source units and normalize exactly with1kW=1,000W; divide the completed aggregate array DC nameplate capacity by the completed exact inverter configuration's total AC nameplate capacity only as neutral arithmetic; then optionally reconcile one independently reported same-record dimensionless ratio inside a reviewer-owned arithmetic tolerance without estimating array output, assuming a target, rounding to a product, predicting clipping/yield/economics, checking electrical compatibility or classifying suitability
The exact system/array configuration, aggregate DC nameplate source/revision/row/basis, exact inverter manufacturer/model/configuration/already-selected quantity, total AC nameplate source/revision/row/basis, source units, method and reviewer must travel together. Irradiance, temperature, soiling, expected output, a target ratio, standard product size, surge/load value, guessed rating, another system/configuration/product/quantity/basis or source revision needs another responsible workflow or is refused.
A DC/AC nameplate ratio or arithmetic-tolerance state is not a sizing, product, performance, compatibility, certification or safety decision. Keep clipping/yield/cost/ROI modeling, product/type/quantity selection, string/module/MPPT voltage/current/temperature checks, loads/motor surge, battery/charger/controller/hybrid/off-grid/grid design, phase/frequency/voltage/waveform, certification, utility/interconnection, code, electrical, fire, installation, commissioning, operation and economic decisions with current exact-product evidence, applicable authorities and responsible qualified professionals.
Choose your path
Built around the job you need to finish
Reconcile one completed already-selected exact PV array's aggregate DC nameplate capacity with one completed already-selected exact inverter configuration's total AC nameplate capacity while preserving both sources, revisions, rating bases, method and reviewer and without sizing or selecting equipment, predicting performance, validating compatibility or approving installation.
PV design-record reviewer reproducing one nameplate ratio
Normalize two source-owned nameplate capacities without losing their exact configuration, quantity, revision, rating basis or responsibility.
Name the record and exact system, retain the array and inverter source rows and bases, enter independently tagged DC and AC capacities, affirm all evidence boundaries, then reconcile.
Receives normalized W/kW values and one neutral dimensionless ratio while every provenance field and nondecision remains visible.
Independent report reviewer checking a completed ratio
Compare another completed same-record ratio without turning arithmetic agreement into product, clipping, yield, compatibility, certification or safety acceptance.
Enter the reported ratio and exact source, optionally add the record owner's arithmetic tolerance, inspect the residual, retain a snapshot, edit a live input and verify stale-result removal.
Can distinguish arithmetic agreement from system approval, with tolerance neutral when absent and retained evidence immutable when the live form changes.
Phone user testing the former inverter-sizing promise
Avoid a product recommendation or performance claim generated from expected array output, a generic target ratio, standard size, load surge, battery mode or guessed rating.
Load the clearly static example, trigger array-source, inverter-source, mixed-record and decision-boundary refusals, recover with one coherent completed record, reconcile, retain and Reset.
Unsupported requests fail at their owning field with no stale result/action, and the Tool never recommends a type, size or quantity, predicts clipping/yield/ROI, validates electrical compatibility or approves safety/installation.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Keep the exact system/configuration, aggregate array DC nameplate source and rating basis, total inverter AC nameplate source and rating basis, revision, method, and responsible reviewer together. Do not substitute expected array output, a target ratio, a standard product size, or another configuration.
Record boundary = one completed exact array configuration + one completed exact inverter configuration
Normalize source-owned nameplate units
Preserve each source value and its W or kW unit, then normalize both capacities to the same power unit. Unit conversion does not validate a rating basis, source row, configuration, product, or design.
1 kW = 1,000 W
Reproduce neutral ratio arithmetic
Divide the completed aggregate array DC nameplate capacity by the completed inverter configuration's total AC nameplate capacity. An optional independently reported same-record ratio and owner tolerance may be reconciled, but neither is a design or acceptance threshold.
DC/AC nameplate ratio = array DC nameplate ÷ total inverter AC nameplate

Example Scenarios
Retain one already-selected exact array schedule and exact inverter configuration, normalize their source-owned nameplate units, and reproduce the ratio without recommending a size or target.
Compare a completed reported same-record ratio with the reproduced ratio and its owner-defined arithmetic tolerance while keeping performance, clipping, compatibility, and approval decisions external.
Use the clearly static example to learn the record boundary. Requests based on irradiance, temperature, soiling, loads, surge, batteries, target ratios, or standard product sizes are refused.
Common Mistakes to Avoid
✕
Mixing configurations, revisions, quantities, or rating bases
✓
Keep both nameplate values bound to one completed exact system/configuration and their source-owned rating bases. Start a separate record when any source, revision, product, quantity, or basis changes.
✕
Treating the ratio as a product or performance verdict
✓
Use the result only as reproducible nameplate arithmetic. Keep inverter selection, clipping and yield modeling, string/MPPT compatibility, off-grid and battery design, certification, interconnection, code, safety, installation, operation, and economics in responsible external workflows.
FAQ
Use one completed exact system/configuration record, the aggregate array DC nameplate source and rating basis, the exact inverter model/configuration/quantity record, its total AC nameplate source and rating basis, the method, revision, and responsible reviewer.
A nameplate ratio alone cannot select or approve an inverter. Product and quantity selection also depends on current manufacturer data, electrical and thermal compatibility, system architecture, loads, interconnection, applicable requirements, and qualified review.
No. Those outcomes require a separate model with location, weather, array orientation, equipment behavior, losses, controls, assumptions, and economic inputs. This record performs no performance or financial model.
No. Load schedules, motor starting behavior, battery and charging limits, controls, voltage, current, waveform, frequency, phase, and operating modes require separate exact-product and system workflows.
No. It means only that two arithmetic values are within the record owner's stated arithmetic tolerance. It is not a clipping, yield, compatibility, certification, interconnection, code, safety, installation, or economic decision.
About PV Array / Inverter Nameplate Ratio Record
Use this record after one exact PV array and one exact inverter configuration have already been selected and documented. Retain their sources, revisions, rating bases, method, and reviewer; normalize W or kW; and reproduce only the dimensionless array-DC-to-total-inverter-AC nameplate ratio. It does not recommend an inverter, target ratio, product type, quantity, or system design.
