Most solar installers don’t lose battery deals because their products are wrong. They lose them because they can’t show the numbers fast enough, can’t prove the value clearly enough, and can’t back up their recommendation with anything other than experience and gut feel. OpusFlow changes that.
You ask the customer roughly how much they use, pick a battery that sounds right and hope it holds up under scrutiny. When the customer pushes back or asks for the maths, there is not much to show them.
The moment a customer asks how long it takes to pay off, you either give a rough number you are not fully confident in or you tell them you will follow up with the figures. That follow-up rarely lands at the right moment.
It doesn’t happen on purpose. But when you’re quoting quickly and pulling from a long product catalogue, it’s easy to recommend a battery that turns out to be incompatible with the inverter already on the quote. That mistake costs time, trust and margin.
Battery size is calculated from actual consumption figures, solar output and usage patterns.
Savings, payback period and long-term return are calculated and presented in a way the customer can actually read.
Only batteries that match the selected inverter and grid connection are shown.

The battery ROI screen has been fully redesigned with dedicated KPI cards, an investment journey chart and a detailed energy flow diagram. Everything is available in one place and exports directly into PDF quotes. Your customer sees exactly what you see, without any extra steps.
OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.
With OpusFlow you can define separate self-consumption percentages for situations with and without a battery. This lets you show customers a transparent side-by-side comparison of their energy situation before and after installing storage. The result is a data-backed recommendation rather than a general estimate.
Adjust electricity prices, feed-in tariffs, dynamic contracts, consumption profiles, battery degradation and efficiency losses to match each customer’s real situation. Every market and energy contract is different, and the calculator reflects that. Changes update ROI and payback time instantly.
Everything you want to know before booking a demo.
Yes! OpusFlow is an ERP system built specifically for sustainable installers. Beyond the full ERP suite, it includes industry-specific tools like a PV Designer and Battery Calculator. All designed to work together in one platform.
OpusFlow is built for sustainable installers: think solar, heat pumps, air conditioning, climate control, and wind farms. General installation companies are equally at home on the platform. Thanks to its modular setup, you simply switch off what you don’t need and focus on what matters to your business.
OpusFlow is an all-in-one business management platform built specifically for solar, heatpump, battery, charging stations and other sustainable energy installation companies. It connects your sales, operations, planning, warehouse, and finance in one system so your whole team works from the same data, not separate spreadsheets messaging apps or other external apps or software.
Yes. A single automation can span multiple modules — for example, when an installation is marked complete in project management, it can trigger an invoice in finance, create a follow-up task for the sales team, and send a completion notification to the customer portal simultaneously. Workflows aren’t limited to one department, and you can build approval chains that route between teams as part of the same sequence.
Yes. The CRM is used by companies installing solar panels, heat pumps, EV charging stations, air conditioning systems, and more. You can tag and filter customers by installation type, which means your pipeline and customer records always reflect the specific products and services your business offers.
No. Automations in OpusFlow are configured through a visual rule builder — you select a trigger, add conditions, and define one or more actions. No code involved. For more complex workflows, pre-configured automation templates give you a proven starting point you can adapt rather than build from scratch. Most teams have their first automations running within an hour of setup.
Yes. OpusFlow’s Multi-Entity Finance feature lets you manage multiple companies, labels, or subsidiaries from a single account. Each entity gets its own branding, invoice number sequences, payment terms, and accounting integration. Projects and quotes are automatically linked to the correct entity, so there’s no risk of invoices going out under the wrong logo or routing to the wrong general ledger.
Yes! With the PV Designer you can design both private and commercial roofs and generate a full calculation and Bill of Materials directly from your installation plan.
Yes. Field-captured photos linked to the project are displayed in a gallery within the portal, including installation progress images and final commissioning shots. It’s a straightforward way to keep customers informed and build confidence in the quality of the work being done.
Customers have access to real-time project milestone tracking, all commercial documents linked to their project, scheduled appointment and survey dates, photo galleries from the installation, and a communication thread with your team. Everything relevant to their project is in one place, presented clearly without exposing any of your internal data or other customers’ records.
Yes. The customer portal displays a visual milestone tracker showing exactly where the project stands, from initial survey through to commissioning. The indicators update in real time as your team progresses the project in OpusFlow, so customers always have an accurate picture without needing to chase your team for an update.
OpusFlow runs a billing engine every night that checks all active contracts and automatically generates invoices for any that are due. There is no manual step required and no risk of a billing run being forgotten because someone was on holiday. The system also includes built-in safeguards that prevent a customer from ever being billed twice for the same period.
OpusFlow currently integrates with Google Workspace, Microsoft 365, Mollie for payment processing, the Dutch 2BA product catalog, Exact and Peppol for accounting and e-invoicing, and AEAT for the Spanish market. For tools not on this list, the open API allows you to build custom integrations and connect OpusFlow to virtually any platform in your existing stack.
Yes. Every ticket is linked directly to the parent project in OpusFlow, which means the moment a service request comes in, the person handling it has immediate access to the original Bill of Materials, installation photos, engineering models, and the full project history. There is no need to search through archives or ask a colleague — the context is already there.
Our team knows the product inside out. Ask us anything — no sales pressure, no scripts.
