Battery Backup & Storage
Keep critical loads running straight through any outage.
Grid outages, whether from load-shedding, storms, or transformer faults, can disrupt operations for businesses with sensitive or continuous-running equipment. Battery backup systems provide seamless power during these interruptions, switching over automatically without the noise, fuel cost, and start-up delay of a diesel generator.
CZ Engineering designs battery backup systems for telecom towers, poultry farms, cold storage, clinics, and offices where even short outages carry real operational or financial cost. Systems can be deployed standalone for pure backup duty or integrated with an existing or new solar array so that the battery is recharged by daytime generation rather than relying solely on the grid.
For sites already running a diesel generator, we typically configure the battery system as the first line of defence, with the generator held in reserve for unusually long outages — reducing fuel consumption and generator wear substantially over the course of a year.
How it works
- 1
Critical load assessment
We identify which loads must stay powered during an outage and how long backup runtime needs to last.
- 2
Battery and inverter sizing
Battery capacity and inverter rating are matched to the critical load profile and desired backup duration.
- 3
Installation and integration
The system is installed and wired into the site's electrical panel, with automatic transfer switching configured for seamless changeover.
- 4
Testing and handover
We run simulated outage tests to confirm changeover time and runtime before final handover.
