Commercial Solar Monitoring & Battery Management
HIT Energy Guard: understand your energy, then act
Commercial solar monitoring should help you decide what to do next. HIT Energy Guard brings operating data and engineering support together so farms and businesses can understand their solar performance, investigate faults and plan how they use energy.
Built in-house by Simon and the HIT team from years of work on commercial and utility solar, Energy Guard supports existing installations as they develop. That can mean keeping an older PV system producing, adding compatible battery storage or assessing the extra demand from electric vehicles.
See beyond a generation total
Depending on equipment and configuration, monitoring can include inverter performance, individual DC string voltage and current, and AC operating data. Suitable systems provide readings at 10-minute intervals. The available detail helps our engineers identify changes and decide where investigation is needed.
We interpret current performance alongside site history and operating conditions. A communications gap needs a different response from an inverter fault or a persistent reduction in output.
Keep productive solar working
If your original installer has stopped trading, equipment is obsolete or the monitoring portal no longer works, HIT can assess the installation and a practical route to ongoing support. We check compatibility and data availability before specifying monitoring equipment.
When evidence points to a fault, we investigate the cause and plan solar PV maintenance and repairs. Targeted repowering is considered where it is justified. A healthy existing array can continue generating while the wider energy system evolves.
From solar monitoring to intelligent battery management
Once we understand how the existing PV is performing, we can assess how stored energy should serve the business. For compatible systems, HIT Energy Guard can bring together battery operation, site demand and electricity tariffs. Where available, generation history and weather forecasts can also help inform charging decisions.
CHARGE · HOLD · DISCHARGE
Charge from available solar or suitable lower-cost grid electricity. Hold energy for the period when it is needed. Discharge within the system’s limits to support site demand. The operating strategy follows your equipment, tariff and business routine.
One platform. One monthly subscription.
Where compatible battery storage is integrated with HIT Energy Guard, intelligent battery management is included within the usual Energy Guard monthly subscription. We confirm the available data, controls and service scope for each installation.
Use measured performance to plan the next investment
Import, export, battery throughput and demand timing help establish whether commercial battery storage, more capacity or additional solar could benefit the site. Seasonal conditions, usable capacity, charge power and tariff arrangements all matter when assessing the business case.
Plan solar, storage and fleet charging together
As farms and businesses introduce electric vehicles, charging adds a new demand to the site. We assess when vehicles are available to charge, how much energy they need and how that fits with other operations. Solar availability, stored energy and the incoming supply form part of the same assessment.
Direct charger control and coordinated load management depend on equipment compatibility and the agreed installation design. The aim is to create a practical energy plan that can develop as the fleet grows.

Energy Guard in practice: Woodlands Farm
HIT’s support for Rob Mutimer’s existing 100 kWp FIT solar array has developed from monitoring and targeted repairs into a 100 kWh battery installation. Across six complete days, 17–22 September 2026, the battery recorded 557 kWh charged and 585 kWh discharged.
A further 100 kWh battery bank has been ordered for the site. Having seen the benefits of its solar and battery installation, the farm is now introducing electric vehicles to its fleet. The first charge point was installed in the week commencing 12 October 2026. The September measurements relate to the original battery bank and predate EV charging.
