System kit and components

Solar system components are prepared together before a backup installation. This example shows an inverter, battery, controller and supporting documentation ready for the site.

Components are checked and prepared before they go to site: inverter, battery, controller, protection and the documentation that goes with them.

Every installation is handed over with labelled circuits and a walkthrough of what each part does.

Make each component fit the design

An inverter, battery and controller have different roles, but they must work as one system. The selected equipment depends on the loads, how long backup is needed and whether solar will recharge the battery. Protection and isolation are also part of the design so the system can be operated and serviced appropriately.

Before installation, the proposed component list should match the written specification. That helps confirm what is included and which circuits the system is intended to support. Product models and ratings vary by site, so this example does not represent a fixed kit or a universal recommendation.

Prepare for a clear handover

Documentation, labelled circuits and recorded checks help the property owner understand the installation. At commissioning, the team tests the system, explains the status indicators and shows the normal operating and isolation points. The handover should make it clear which loads are covered and when a service visit may be needed.

During a load assessment, list the appliances and note which ones start together. Separate loads that need backup from those that can stay on the grid, then estimate the hours they should run. That information informs the inverter, battery, controller and protection choices. It also makes a proposal easier to review because the covered circuits and design assumptions are written down. If the site has existing equipment, share its labels and specifications where available instead of guessing at compatibility.

Good preparation makes solar system components easier to install and explain, but a parts list alone cannot size a system. Request a load assessment so SIDAI can specify equipment around your property.
