What this system decides for your project
Storage keeps critical loads running through outages and lets you use solar after sunset — essential where grid supply is weak or expensive at peak hours.
You need a quote for this if: Sites with poor grid reliability or high peak tariffs.
Scope of work
Storage is sized from two questions — which loads must run through an outage, and for how long — and, where the tariff justifies it, how much daytime solar should be shifted to evening use. From that follow the battery chemistry and capacity, the hybrid inverter with the charge and discharge rates the bank supports, the battery management system, and the wiring of critical loads onto the backed-up circuit. We supply and install the batteries, hybrid inverter, BMS, distribution and the protection.
How it is delivered — and what you receive
The system is commissioned through a simulated outage — the critical loads must transfer and run for the design duration — and the charge and discharge limits set to protect the battery's cycle life. Ventilation and fire precautions for the battery room are checked. The client receives the sizing calculation, the settings record and the operating limits the AMC will monitor.
