Duty cycle definition
We establish what the battery must actually do, using half-hourly or billed consumption data and your operational priorities.
- Load shifting of solar surplus
- Peak demand reduction
- Backup for critical loads
Sizing & chemistry
Capacity, power rating and round-trip efficiency are matched to the duty cycle and expected cycle count.
- kWh and kW sizing
- Cycle life and depth of discharge
- LFP and hybrid inverter options
System architecture
AC-coupled, DC-coupled or hybrid configurations, with critical load separation where continuity matters.
- AC vs DC coupling
- Essential load board design
- Generator interaction
Controls & dispatch
Setpoints and control logic so the system behaves as modelled instead of drifting into unprofitable operation.
- Charge / discharge windows
- Demand limit setpoints
- Monitoring and alarms
Safety & compliance
Placement, ventilation, fire separation and protection reviewed against applicable standards and insurer expectations.
- Enclosure and location review
- Protection and isolation
- Documentation and CoC
Commercial modelling
Storage is only added where the modelled benefit justifies it, tested in the same financial model as the PV.
- Demand charge savings
- Outage cost avoidance
- Effect on IRR and payback
Storage performance and savings depend on tariff structure, load behaviour and operating discipline. Figures presented in our models are engineering estimates based on the documented assumptions in each report.
Size a storage system properly
Send your electricity bills and a note on which loads must stay up, and we will model whether storage earns its place on your site.
