Enterprise Solar CMMS on Microsoft 365
Stop Renting Your Software. Own Your Solar Operations.
The only CAPEX-model CMMS built on your existing Microsoft 365 tenant. Eliminate monthly fees, secure your data, and scale your portfolio without limits.
Your CMMS Wasn’t Designed for the Business You’re Building.
SaaS platforms made sense when you managed a pilot project. They make less sense when your portfolio is scaling, your data is mission-critical, and you realise your vendor’s renewal email arrives whether your assets are generating or not.
Pain Point #1
SaaS Cost Spirals
Every technician you hire costs another seat licence. Every plant you commission costs another tier upgrade. You are not paying for software — you are paying a growth tax.
Pain Point #2
Vendor Hostage
Last quarter your vendor deprecated a feature you had built workflows around. You filed a ticket. It is on the roadmap. You are still waiting.
Pain Point #3
Data Fragmentation
Your field team uses one system. Finance uses another. Compliance reports live in a third. When an investor asks for an asset health summary, someone spends three days compiling it from four sources.
Pain Point #4
Adoption Resistance
You spent six figures on implementation. Eighteen months later, half your technicians are still emailing photos and calling in faults. The software was the easy part.
Pain Point #5
Rigid Workflows
Your OEM changed their inspection protocol. Your SaaS vendor quoted eight weeks and a change-request fee. You did it in Excel instead.
Pain Point #5
Connectivity Gaps
Your best technician is offline at a remote site for four hours. Everything they touch today creates paperwork tomorrow.
From SCADA Alert to Investor Report — One Platform, One Tenant, Zero Gaps.
Most solar CMMS platforms are built to log what happened. Five Hundred is built to own what happens next. Every Work Order, every warranty claim, every performance metric lives inside your Microsoft 365 environment — not in a vendor’s hosted database. The architecture is not just better engineered. It is yours.

Executives
Ownership & Scalability
Secure your asset data and eliminate vendor lock-in risks.
You have built a portfolio worth protecting. Do not put its operational data in someone else’s hands.
Five Hundred deploys inside your Azure tenant. Your operational data — every asset record, every maintenance log, every compliance document — is yours. No vendor acquisition risk. No price renegotiation at renewal. No data portability negotiation when you decide to switch. You own the platform the same way you own the plant.
Finance
CAPEX Investment vs. OPEX Drain
Stop paying rent. Shift to a sustainable cost model.
Stop treating critical software as an operating expense. It is a capital asset — price it like one.
Five Hundred is a one-time CAPEX investment. You pay for implementation. You own the platform. As your portfolio grows from 100MW to 500MW, your software cost does not move. No per-user escalation. No inflation-linked renewal. No hidden API fees when you connect a new SCADA system. TCO breakeven in under 18 months compared to the SaaS alternatives.
IT Managers
Security & Governance
No new silos. Integrated natively into your Azure environment.
One more SaaS integration is not a capability. It is a vulnerability.
Five Hundred adds zero new attack surfaces. It deploys natively on your existing Azure infrastructure, governed by the same Entra ID MFA protocols and the same GDPR-compliant data residency you already enforce. Your helpdesk does not learn a new system. Your security team does not audit a new vendor. Your compliance reports do not require a new data processor agreement.
O&M Managers
Field Efficiency
Tools that work offline and simplify the technician’s day.
The field does not have time for software that stops working when the signal does.
Five Hundred runs on Microsoft Power Apps with true offline capability. Your technician scans the inverter QR code, opens the complete asset history, completes the checklist, and attaches photo evidence — without a bar of signal. Everything syncs the moment they are back in range. No manual reconciliation. No paper-to-digital transcription. No lost reports.
Preventive Maintenance (PM)
Forget spreadsheets. We automate the creation of recurring tasks to ensure 100% compliance with OEM warranties. Power Automate handles the scheduling logic, ensuring no inspection is ever missed.
Automated Recurrence Patterns
Set schedules once (e.g., ‘Every 6 Months’ or ‘Every 1st Monday’) and let the system auto-generate Work Orders with attached checklists.
- Warranty Compliance
Link maintenance protocols directly to asset warranties. System alerts you if a mandatory torque check is overdue, preventing warranty voiding.
- Standardized SOPs
Technicians receive digital checklists specific to the asset type (e.g., ‘Huawei 100KTL Annual Service’), ensuring uniform execution quality.


Corrective Maintenance (CM)
Minimize downtime with SCADA-integrated incident management. The system filters noise, auto-creates tickets for real faults, and tracks Mean Time To Repair (MTTR) to optimize performance.
- SCADA & IoT Integration
Direct ingestion from data loggers. An ‘Inverter Fault 2062’ alarm instantly triggers a CM Work Order, pre-filled with error codes and location data.
- Intelligent Triage
Auto-assign priority. Critical production losses (P1) alert the site manager via Teams immediately, while minor warnings (P4) are queued.
- MTTR Tracking
Measure the exact duration from ‘Alarm Triggered’ to ‘Technician Check-in’ to ‘Resolution’, identifying bottlenecks in your O&M response.
Environmental, Health & Safety (EHS)
Protect your workforce and minimize liability. Our EHS module is natively integrated into maintenance workflows, ensuring compliance with OSHA, ISO 45001, and local regulations through mandatory digital sign-offs.
Digital LOTO Verification
Enforce zero-energy verification. Technicians cannot proceed with high-voltage tasks without capturing photo evidence of locks and tags.
- Mandatory JSA/JHA
Job Safety Analysis is embedded in the Work Order. Hazards must be acknowledged and mitigation steps checked before the clock starts.
- Real-time Incident Reporting
Capture near-misses and accidents instantly from the field. Triggers immediate alerts to EHS managers and automated investigation workflows.


The Office in Your Pocket
Empower your workforce with a native Power App designed for the harsh realities of solar fields. It handles complex data synchronization automatically, so your team focuses on fixing, not waiting for signal.
True Offline Capability
Work continues without signal. Technicians access data and upload evidence locally, with background syncing once they return to coverage.
QR-Asset Intelligence
Scan a QR code on an inverter or string box to instantly pull up its entire life history, warranty status, and schematics instantly.
- Multimedia Verification
Attach high-res photos and videos directly to the asset record. Every maintenance task is verified with visual proof from the field.
Intelligent Asset & Inventory Control
Stop managing millions in assets using spreadsheets. Our Digital Twin architecture tracks every Serial Number (S/N), swap, and spare movement in real-time.
- Hierarchical Registry
Organize assets logically: Park > Zone > Station > Device. Find every module instantly.
- S/N Swap Audit
Capture ‘Old S/N’ and ‘New S/N’ automatically. Updates the Digital Twin history instantly.
- RMA & Claims
Streamline vendor returns. Generate warranty PDFs populated with fault codes automatically.

The Comparison That Changes How You Think About Software.
Every SaaS vendor will tell you their subscription model is flexible. What they mean is that it is flexible for them — prices flex upward at renewal, features flex behind paywalls, and your data remains in their infrastructure until you decide to leave and discover what data portability actually costs. Compare what you own against what you rent.
| Type | Five Hundred | Traditional SaaS |
|---|---|---|
| Data Ownership | ✔ You Own It (Client Tenant) | ✖ Vendor Owns It (Hosted) |
| Cost Model | ✔ CAPEX (One-time Platform) | ✖ OPEX (Recurring Subscriptions) |
| Scalability Costs | ✔ $0 for extra Users/Plants | ✖ Costs rise with Growth |
| Integration | ✔ Native (Teams, Excel, BI) | ! Requires Paid API Connectors |
| Customizability | ✔ Open (Power Platform) | ! Closed (Vendor Roadmap) |
| Field Mobility | ✔ Offline-First Mobile App | ! Connectivity Dependent |
| Security Architecture | ✔ Azure AD / Entra ID | ! Proprietary / Siloed |

Frequently Asked Questions
Clear answers about our CAPEX model, Microsoft 365 integration, and data security.
You pay once. That is it. Five Hundred is a CAPEX investment, not a subscription. You pay an implementation fee to build and deploy the platform inside your Microsoft 365 tenant. After that, the software is yours — no monthly fees, no per-user seat costs, no renewal negotiations. As you add plants, technicians, or sites, your software cost does not change. Most clients reach TCO breakeven inside 18 months compared to the SaaS alternative they were considering.
Yes. The WIZSP Power App is **offline-capable**. Technicians can download work orders, view schematics, complete checklists, and capture photos in remote locations. Data automatically synchronizes with the cloud once connectivity is restored.
Your data never touches our servers — because we do not have any. Five Hundred deploys natively inside your Microsoft Azure tenant. We install software. We do not host data. Your operational records, asset histories, maintenance logs, and compliance documents live in your environment, governed by your Azure AD policies, audited by your security team. We have no more access to your data than your own IT department decides to grant us. For critical infrastructure operators, that is not a feature. It is the only acceptable architecture.
Your data is secured by Microsoft Azure. WIZSP installs directly into your tenant, meaning your data never leaves your control. You benefit from Microsoft’s enterprise-grade security, including MFA, SSO, and compliance certifications (GDPR, ISO 27001).
WIZSP integrates with your existing SCADA / Data Loggers via API or email parsers. It filters ‘noise’ and automatically converts critical alarms into Work Orders, routing them to the correct technician based on the fault type.
Migration is streamlined. Because WIZSP utilizes Dataverse, we can import asset registries and historical data from Excel, CSV, or legacy SQL databases efficiently, ensuring you retain your historical maintenance records.
Yes. The architecture supports unlimited sites and assets. Whether you manage 10MW or 10GW, the system scales without performance degradation. Furthermore, the CAPEX model means your costs do not increase linearly as you add more assets.
