Backup is not just
a battery size.

Effective load shedding backup starts by separating critical household needs from high-demand appliances, then matching battery energy, inverter power and available solar to the target backup window.

“What must stay on, for how long, and what can wait?”
A resilient daily cycle

Solar by day.
Stored energy after dark.

The system uses available solar first, stores surplus energy and preserves a defined reserve for planned or unexpected grid interruptions.

06:00Morning

Solar begins supporting household loads and battery recovery.

12:00Midday

Surplus solar charges the battery after current demand is met.

18:00Evening

Stored energy helps cover peak household consumption.

OUTAGEBackup

Priority circuits continue within the designed system limits.

Start with a capacity range

Three useful
planning points.

These examples are content and interface prototypes, not electrical designs. A qualified installer must confirm loads, inverter power, wiring, protection and final runtime.

5

5 kWh class

Focused essential loads and shorter backup windows.

LIGHT BACKUP
10

10 kWh class

Broader daily coverage for a typical selected-load system.

BALANCED HOME
16

16 kWh class

More energy for larger selected loads or extended reserve.

EXTENDED BACKUP
Designed for the installation environment

Heat, dust and placement matter.

The site survey should confirm indoor or protected outdoor placement, temperature range, ventilation, access, mounting or floor support, cable routes and local electrical protection requirements.

Request technical review
For South African installers

Make the next quote easier to verify.

01Share the customer load list and required backup window.

02Confirm the proposed hybrid inverter model and power rating.

03Check battery communication and system settings.

04Request the current datasheet, warranty and approved compatibility records.

Questions to settle before the quote.

These answers form the SEO and sales content spine for the regional page. Technical values remain tied to the selected model and installer design.

How much battery capacity does the home need?+

Start with the essential-load list, expected watts, surge demand and desired backup hours. Solar availability and usable battery energy then shape the suitable capacity class.

Can the battery power the whole house?+

That depends on inverter output, wiring, appliance surge current and the chosen backup architecture. Many homes separate priority circuits from high-demand loads.

Can an existing solar system be retained?+

Possibly. The installer must review the existing inverter, system voltage, communication method, protection and whether an AC- or DC-coupled approach is appropriate.

What documents should be checked?+

Use the current datasheet, installation manual, market warranty, approved compatibility record and any applicable certificate for the exact model revision.
