Battery energy storage (BESS) for businesses, farms and off-grid sites

Store solar and off-peak power, cut demand charges and keep running through outages at farms, remote sites, factories, warehouses, office parks, Gauteng businesses, retail centres and schools.

Off-grid sites: power where the grid can’t reach

Off-grid power is a core part of what we do. For farms, remote sites and anywhere without a reliable grid connection, we design solar and battery systems that supply your power around the clock, with the battery carrying your load through the night and cloudy spells.

  • Farms, irrigation, cold rooms and farmhouses
  • Remote sites, lodges, telecoms and pumping stations
  • Sites where a grid connection is unavailable, unreliable or too costly to extend

We size the solar array and battery bank to your actual daily load so the site stays powered without relying on Eskom.

What a battery system does for your business

A battery energy storage system (BESS) stores electricity and releases it when it is worth the most. For grid-connected businesses that means:

Peak shaving: cut your kVA demand charges

Many commercial and industrial tariffs charge for your highest demand in the month (kVA), not only for the energy you use. A battery discharges during your demand peaks so the grid sees a lower maximum, which reduces the demand charge on your bill.

Energy arbitrage: buy cheap, use at peak

On time-of-use tariffs such as Eskom Megaflex, peak-period energy costs far more than off-peak. A battery charges from cheap off-peak power or surplus solar, then supplies your site during the expensive peak periods.

Clean power: get more from your solar

Without storage, solar generated when your site is quiet is exported or curtailed. A battery stores that surplus so you use more of your own clean solar power in the evening and early morning, which optimises your solar investment and lowers your reliance on the grid. See commercial and industrial solar.

Backup during load-shedding and outages

When the grid goes down, the battery takes over essential loads so lights, tills, IT, security and critical equipment keep running through load-shedding and unplanned outages.

How it works

  1. Assessment: we review 12 months of electricity bills or interval-meter data, your tariff and your load profile.
  2. Sizing: we size battery capacity and inverter power to your goal, whether that is peak shaving, arbitrage, backup or full off-grid supply.
  3. Design: we design the system around your site, existing solar and grid connection.
  4. Installation: our team installs and commissions the system, including SSEG registration where it applies.
  5. Monitoring: we monitor performance so you can see what the system is doing and saving.

Frequently asked questions

What is a BESS?

A battery energy storage system (BESS) stores electricity from solar or the grid and supplies it to your site when you need it.

Can a battery system power an off-grid site?

Yes. Paired with solar and sized to your daily load, a battery system can power farms, remote sites and other sites without a reliable grid connection.

How does a battery reduce my demand charges?

It discharges during your highest-demand periods, lowering the peak kVA the grid sees, which reduces the demand charge on your bill.

Can I add batteries to my existing solar system?

Often, yes. We assess your current inverter and system to confirm what is compatible before recommending a design.

How do you size a battery system?

We start with 12 months of bills or interval-meter data and your goals, then size capacity and power to suit your load.
