Battery storage
BMS, power conversion, cooling, fire systems and capacity tests.
Operations & maintenance
Operations and maintenance
We monitor, maintain and test batteries, chargers and the equipment around them, and report every month, including on systems others installed.
What we look after
What we maintain
Storage, charging and the equipment around them, under one AMC and one monthly report.
EV chargers
AC, DC and light-EV chargers: connectors, cables, power modules and OCPP links.
Solar tied to storage
Inverters, strings and protection where solar feeds storage or chargers.
Genset hybrid controls
Changeover and hybrid-controller settings, with your genset service provider.
Monitoring & EMS
Energy 107 schedules, limits and alarms, kept in tune with the site.
Switchgear & metering
Thermal surveys, protection checks and metering records.
Takeovers
Taking over existing systems
For systems whose installer or warranty support has gone, we start with a baseline of their condition.
Document review
Drawings, test reports, warranty
Baseline inspection
Visual, thermal, alarms, logs
Capacity & efficiency test
IEC 62933-2-1, or charger function tests

Battery upkeep
Battery maintenance schedule
Typical scope; final frequencies follow the maker's manual and your AMC.
Continuous
- Remote monitoring of alarms, temperature and charge
- Alarm response as agreed
Monthly
- Visual inspection and cooling checks
- BMS log and cell-voltage review
Quarterly
- Thermal scan of connections
- Fire and gas detection checks
- Emergency-stop and door-alarm tests
Annual
- Torque re-checks on terminations
- Energy and efficiency test (IEC 62933-2-1)
- Suppression-system inspection
- State-of-health review against warranty
Charger upkeep
EV charger maintenance
Some faults can be cleared remotely; the rest need hands, tools and the right spares.
Remote
- Connectivity and heartbeat alarms
- Error codes and stuck sessions
- Remote resets and connector release
On site
- Connector and cable inspection
- Thermal scans of panels and terminations
- RCD trip and earth-continuity tests
- Payment terminal and network checks
Spares we plan for
- Connector and cable assemblies
- Power modules
- Control and communication boards
Reporting
Monthly reporting
One short report, in the same layout every month.
- Energy in and out; round-trip efficiency
- Availability, with exclusions listed
- Alarms, responses and time to resolve
- Peak demand against the set limit
- Charger sessions, availability and faults
- Maintenance done and next actions
AMC
What an AMC covers
Each contract sets out who does what, how fast, and what's excluded.
Scope
Which equipment, visits and tests, and the compliance records we keep.
Response
How alarms are handled and response times, agreed per site.
Spares
What we hold, what the owner holds.
Exclusions
Grid outages, vandalism, misuse, maker warranty items.
Measures
Availability, session success rate and repair time, defined in the contract.
Review
An annual review of scope and results.
Questions about O&M
Yes. We start with a baseline inspection and capacity test, so we both know the condition we are taking on.
We follow the maker's manual, use approved parts and log everything, and coordinate where the maker requires its own engineers.
Yes, if the chargers speak OCPP and we are given access to the management software, or the network shares alerts with us.
We look after the hybrid controls, changeover and synchronising settings, and coordinate with your genset service provider for the engine and alternator.
