Battery Energy Storage Systems

Battery storage sized for a clear purpose, whether backup, peak reduction or using more of your solar energy, and designed safely for Saudi conditions.

Use more of your solar energy and protect critical loads

Overview

A battery energy storage system (BESS) stores electricity, from solar panels or the grid, and releases it when needed. It combines battery modules, a power conversion system, a battery management system, cooling and fire protection. Storage is used to keep critical loads running during outages, reduce peak demand, shift solar energy to the evening and support EV charging where grid capacity is limited.

Solar panels produce during the day, while many homes, compounds and facilities still need power in the evening or during peaks. Battery storage closes that gap. It increases the share of solar energy you actually use, provides backup for critical equipment and can reduce the peak demand that drives connection size and costs.

Storage is only valuable when it is sized for a specific purpose. A battery chosen for backup is configured differently from one meant for peak shaving or for supporting fast chargers. Battery chemistry, heat, ventilation, fire safety and the rules for operating alongside the grid all affect performance, lifetime and risk, especially in hot climates.

Selorin designs and delivers storage systems for residential, commercial and industrial sites and alongside solar and EV charging projects. We analyse load data to define the use case, size capacity and power, select suitable technology, and design cooling, fire protection and controls. We then install, commission and monitor the system, and plan for responsible collection and recycling of batteries at end of life.

When you need this service

You may need this service when:

  • You have, or are planning, a solar system and want to use its energy after sunset.
  • Critical loads such as cold rooms, servers or medical equipment need backup power.
  • Peak demand charges or limited connection capacity are constraining your site.
  • You are adding EV fast chargers on a connection with limited capacity.
  • You need a safe, compliant design for batteries in a building or compound.
  • You want a plan for monitoring battery health and managing end-of-life batteries.

What we deliver

01

Use-case and load analysis

Analysis of consumption data to define whether storage is for backup, peak reduction, solar self-consumption or EV support.

02

Sizing and technology selection

Energy and power sizing, battery chemistry and configuration selected for performance, lifetime and safety in high temperatures.

03

Safety and integration design

Cooling, ventilation, fire detection and suppression, protection and control integration with solar, generators and the grid.

04

Installation and commissioning

Supervised installation, functional testing of operating modes and handover with operating procedures.

05

Monitoring and health tracking

Remote monitoring of state of charge, temperature and degradation, with alerts and periodic reports.

06

End-of-life planning

A plan for collection, reuse or recycling of batteries through licensed channels.

Our approach

  1. Define the purpose

    We confirm what the storage must achieve and how its value will be measured.

  2. Size and select

    We size the system and compare technology options, costs and lifetime.

  3. Design safely

    We design cooling, fire protection and controls for the location and climate.

  4. Install and test

    We install the system and test every operating mode before handover.

  5. Monitor and maintain

    We track performance and battery health and maintain the system over its life.

Regulatory context

  • Water and Electricity Regulatory Authority requirements for equipment operating in parallel with the grid.
  • Civil Defense and Saudi Building Code fire-safety provisions for battery installations in buildings and sites.
  • SASO conformity requirements for batteries, inverters and electrical equipment.
  • National Center for Waste Management (MWAN) requirements for handling and recycling batteries and electronic waste.

Requirements vary by activity, location and permit conditions. We confirm the applicable requirements for your project at the start of every engagement.

Frequently asked questions

Do I need batteries with a solar system?

Not always. If most of your consumption happens during the day, a grid-connected solar system without batteries can be the most economical choice. Batteries add value when you need backup, use most energy in the evening, or face peak demand or capacity limits.

How long can a battery power my home or facility?

It depends on the battery's stored energy and the loads connected. We size the system for the loads and duration you need, for example keeping essential circuits running during an outage, rather than the whole building.

Are batteries safe in hot climates?

Yes, when the chemistry, cooling and enclosure are chosen for the climate and the installation follows fire-safety requirements. Temperature management is a central part of our design.

How long do battery systems last?

Lifetime depends on chemistry, temperature and how deeply and often the battery is cycled. We estimate expected degradation at design stage and monitor battery health during operation.

What happens to batteries at end of life?

Batteries must be collected and recycled through licensed channels. We include an end-of-life plan in the project so this is arranged responsibly.
