Commercial Solar Monitoring: What KMM Customers Get

What's included as standard

Every KMM commercial install ships with manufacturer-provided cloud monitoring at panel-string level. The portal is accessible via web browser and mobile app, with live generation, daily/monthly/annual totals, alarm response and historical trending. For Sungrow installs this is iSolarCloud; for SolaX it is SolaXCloud; for Solis it is Solis Cloud. All three platforms provide:

• Live generation updated every 5 minutes
• Per-string current and voltage — isolate underperforming strings instantly
• Inverter alarm history with cause codes
• Energy yield trending daily, monthly, annual
• Performance ratio (PR) against modelled output — fast indicator of dust or component degradation
• Self-consumption ratio (with optional CT clamp on the consumer unit incomer)
• Carbon offset accumulator — tCO2e displaced to date, useful for ESG reporting
• API access for integration into BI tools or BMS

What KMM monitors on your behalf

Service-plan customers get KMM operations team eyes on the data:

• Daily underperformance alarms — if any string is 15%+ below modelled output for the conditions, we investigate
• Weekly performance review — automated PR check against weather-corrected baseline
• Monthly written report — generation, kWh consumed, kWh exported, alarm log, recommendations
• Quarterly ESG report — formatted for SECR / GRESB / ESRS E1 / CDP inclusion

Optional BMS integration

For larger sites we can integrate the inverter data into your Building Management System over RS485 modbus or BACnet. Useful for:

• Production scheduling — defer discretionary loads to high-solar windows
• HVAC pre-cooling — let solar pre-cool the building in summer rather than running grid air-con later
• Battery dispatch decisions — integrate solar forecasting into smart battery scheduling
• Real-time dashboards — display in reception, meeting rooms, on factory floors

BMS integration cost: £1,800-£4,500 depending on system size and BMS complexity. Typically pays back in 6-12 months through 3-7% additional self-consumption.

Tenant-facing dashboards

For multi-tenant commercial buildings, we install a tenant-accessible web dashboard showing the shared solar system's generation, total kWh consumed by all tenants, and a per-tenant attribution based on metered consumption or floor-area allocation. Used as part of the service-charge transparency package.

Alarm response

Common alarms and KMM's response:

• String underperformance — desktop investigation first (shading, weather, time-of-day); site visit within 5 working days if cause isn't clear
• Inverter fault — firmware update attempted remotely; engineer visit within 5 working days for hardware
• Communications dropout — usually router or SIM-card issue at the site; we coordinate remote fix or visit
• Earth fault — site visit within 24 hours for safety
• Battery alarm — manufacturer warranty claim coordinated by KMM if applicable
