Storage planning starts with what you need to power–and for how long.
A battery energy storage system (BESS) stores electricity for use when needed. Its suitability depends on your energy source, electrical infrastructure and the job you expect it to perform.
SESCO’s BESS enquiries focus on industrial and commercial requirements, including essential-load backup, solar energy storage and peak-load management where technically suitable.
Tell us about your operating hours, existing equipment and power requirements. These details form the basis of the assessment.
Identify the equipment that needs power during an interruption. Its running demand, starting requirements and required backup duration help determine the storage configuration.
Backup operation depends on the complete system design, including suitable controls and protection.
Solar battery storage can retain energy for use outside the hours in which it is generated. The assessment compares available solar generation with consumption patterns and battery operating limits.
For suitable sites, storage may help manage periods of higher electricity demand. Feasibility depends on the load profile, tariff structure and how the system will be operated.
Adding storage requires a review of the current inverter, electrical arrangement and controls. Existing solar capacity alone does not establish whether a battery addition will work.
Your proposal should distinguish the system’s power output from the amount of energy it can deliver over a period of use.
Which equipment will operate together? Running loads and starting demand influence the required output.
How long must those loads remain supported? That duration helps determine how much usable stored energy the system requires.
Battery recharging must fit around the solar energy and grid supply available during your site’s operating schedule.
Installation planning accounts for the space and conditions at your site, while integration requires a review of existing equipment and electrical infrastructure.
An existing solar installation may be suitable for a storage addition, but the integration approach needs assessment.
Share your inverter make and model, system capacity, electrical drawings where available and the loads you want the battery to support.
AC-coupled and DC-coupled arrangements can involve different equipment and design requirements. The appropriate option depends on the site and the proposed system.
Explain the problem you want storage to address: backup duration, essential equipment, solar utilisation or peak demand.
Provide electricity bills, demand data and existing equipment details. A visit may be necessary to check the conditions in which the equipment will be installed.
Review the proposed output, usable capacity, integration approach and operating assumptions.
Confirm equipment, responsibilities, exclusions, commercial terms and delivery milestones before proceeding.
Approved project summaries will identify the customer’s requirement, SESCO’s responsibilities, and the delivered scope when verified details are available.
Backup is one possible application. Other BESS applications include storing solar electricity for later use and managing demand. Each application calls for an appropriate combination of equipment and controls.
Capacity depends on the loads you want to support, their operating duration and the system’s usable energy limits. For an industrial assessment, include any available records showing how the site’s electrical load changes over time.
That depends on the facility’s demand and the system design. Some projects prioritise selected essential loads rather than every connected load.
Compatibility must be checked. To assess a battery addition, we need your inverter model, installed solar capacity and details of how the electrical system is connected.
The financial outcome depends on tariffs, consumption, charging conditions, equipment costs and operation. Any estimate should use your site’s data and clearly stated assumptions.
Backup duration varies with the connected load, usable battery capacity, operating conditions and system settings. It should be calculated for the equipment you intend to support.
Warranty coverage depends on the selected equipment and manufacturer conditions. Installation coverage and SESCO’s service responsibilities must be stated separately.
Whether you are reviewing an existing solar system or planning a new project, start with the loads and operating conditions the battery must serve.
