Walton Secure x Insytly: Proving Off-Grid Reliability in the Winter
The Overview
Project: Long-term Solar CCTV Tower Deployment
Location: Edinburgh, Scotland
Outcome: 100% uptime through critical winter period, zero site visits
About Walton Secure
Walton Secure designs and manufactures advanced security systems engineered to meet the unique demands of every client. Their portfolio includes fully customisable solar, battery, and mains-powered CCTV towers, integrated with leading-edge technologies such as Davantis DFUSION AI detection, TrashCam, and Ajax Rapid Deployment Systems.
The Challenge
“The Winter Gap”
For any off-grid security installer, the period between November and January is the critical stress test. Short daylight hours and persistent cloud cover typically result in energy deficits. This is where the power consumed by critical security equipment exceeds the limited solar harvest available during the day.
The Visibility Problem
Walton Secure was confident in their engineering, but to win trust in a market often skeptical of solar reliability, they needed more than just assurances – they needed empirical proof.
The objective was clear: demonstrate that their systems could sustain a 24/7 recording schedule through the Scottish winter without manual intervention. Crucially, they also required total fleet visibility to ensure that if an anomaly did occur with their towers, they would be the first to know.
This is where Insytly stepped in.
The Solution
Visibility That Reduces Site Visits
Walton Secure’s towers were equipped with the Insytly IY-HUB2, providing complete visibility into the power architecture without adding to the energy burden.
By integrating directly with Victron solar controllers and battery banks, the solution delivered:
- Battery Health Insights: Continuous monitoring of voltage and State of Charge (SoC) replaced guesswork with precise data. The team could see exactly how much reserve capacity remained, which was critical during consecutive overcast days when solar yield collapsed.
- Solar Yield Analysis: Exact Watt-hour harvesting data logged against weather conditions. When yield dropped from 2.06kWh to 0.02kWh in three days, the team knew immediately, and could verify the system was handling it without intervention.
- Early-Warning System: Custom thresholds trigger instant notifications to the right team members if critical data points drop. Staff can immediately analyse the data via the mobile app to determine if a site visit is actually required, preventing unnecessary call-outs.
- Remote Control: The capability to remotely reboot connected equipment (such as routers) instantly via the cloud, eliminating the need for costly engineer call-outs just to cycle power.
- Low Power Draw: The IY-HUB2 is designed to consume minimal power during active reporting, ensuring the monitoring infrastructure never competes with critical security equipment for energy reserves.
Performance Data (The “Winter Test”)
Data Source: Insytly Platform
Location: Edinburgh, Scotland
Data Window: Dec 1st, 2025 – Jan 8th, 2026
The metrics below confirm system robustness of the CCTV solar tower during the lowest solar yield weeks of the year:
| Metric | Result | Note |
| Peak Solar Yield | 2.06kWh (Dec 20th) | Demonstrates the array’s ability to rapid-charge on clear winter days. |
| Low Solar Yield | 0.02 kWh (Dec 23rd) | A 99% drop just 3 days later due to heavy overcast. |
| Lowest Battery SoC | 55% | Even after consecutive dark days, the system retained over half its capacity. |
| Lowest Recorded Voltage | 13.02V | Voltage remained exceptionally stable, indicating a healthy battery bank. |
| Maintenance Visits | 0 | No fuel costs, no travel time, no emergency visits. |
| System Uptime | 100% | Continuous operation with zero intervention. |
Visual Evidence

Figure 1: Customisable Insytly dashboard showing system performance in action. Note the spike on the 20th followed by the flatline on the 23rd. Despite this, the Battery SoC (State of Charge) line remains stable above 55%.

Figure 2: Comparison of daily Solar Yield (Right) against Battery Voltage (Left). Note that while solar yield fluctuates wildly the battery voltage remains stable above 13V, confirming the tower’s ability to operate independently during extended periods of darkness.
Confidence in the Field
This deployment proves that with correct system design and intelligent monitoring, “winter anxiety” is obsolete.
The Insytly IY-HUB2 didn’t just monitor the towers in their fleet – it provided the empirical proof Walton Secure can show customers: real-world performance data from Scotland’s darkest months.
The Insytly system proved that even when solar yield dropped to a negligible 0.02kWh on the worst day, and with consecutive days of heavy overcast, the asset remained secure and operational.
The Business Impact
Walton Secure can now continue to deploy their off-grid CCTV towers with total confidence. They know their systems will perform, and they have the monitoring infrastructure to prove it to customers before, during, and after installation.
Furthermore, customisable alerts ensure that if an anomaly does occur unexpectedly, the team is notified instantly, allowing for rapid response before an outage occurs.
For off-grid installers, this changes the conversation with customers from “Will it work in winter?” to “Here is the proof.”
“Insytly gave us total confidence through the toughest winter conditions. With full visibility and zero site visits, our off-grid CCTV tower delivered 100% uptime – even during prolonged periods of near-zero solar yield. The real-world data has transformed how we prove reliability to our customers.”
