All features at a glance

kWise covers the complete management of a virtual self-consumption community – from importing smart meter data to the annual closing of the shared installation.

Energy data import

Your grid operator's load profile data lands in kWise without detours – manually or fully automated.

XML import via drag & drop in the ValidatedMeteredData format (1.5 and 1.6, official strom.ch schemas)
Automatic email import: data deliveries from the grid operator are read in directly
15-minute load profiles, other intervals possible
Validation on import – faulty deliveries are detected

PV power distribution

The heart of a vZEV: the production of the shared photovoltaic system is allocated mathematically to all participants.

Automatic allocation of PV production per 15-minute interval
Self-consumption, surplus feed-in and residual grid supply per participant
Configurable distribution schemes for the allocation
Traceable calculation as the basis of every invoice

Consumption analysis

Understand where the solar power flows: interactive analyses for the whole community and every single connection.

Consumption, PV production, grid supply and balance over time
Totals for the vZEV or detailed view of individual metering points
Freely selectable period with interactive time filtering
The same views for participants in the portal

Invoicing

The distributed kilowatt hours become finished invoices – based on your tariffs and in the Swiss standard.

Invoice runs at freely definable intervals (monthly, quarterly, yearly …)
Swiss QR-bill, PDF/A compliant for long-term archiving
Dispatch by email with customisable templates
Tariff-based: peak/off-peak, metering fees, PV day/night discounts
Full control: regenerate, revoke, mark as paid

Example: view a finished QR-bill as a PDF

Accounting & cost allocation

Complete, audit-proof bookkeeping for the shared installation – also suitable for generation cooperatives and condominium owners' associations.

Double-entry bookkeeping with a gapless numbered journal and PDF receipts
Cost allocation to the co-owners – by ownership shares or in equal parts
Tax and rebilling categories per cost account (rechargeable / deductible)
Budget per financial year with target/actual comparison and account groups
Balance sheet, income statement, annual closing and balance carry-forward

Participant portal

All participants can see their own data at any time – that builds trust and saves queries.

Individual login for every participant
Consumption and load profile data, invoices and documents at hand
Co-owners get read-only access to the accounts (journal, reports, budget)
German, French, Italian, English – including dark mode

And beyond that
