Most home battery installs take one to three days once equipment is on site. We confirm the timeline in your proposal after the site survey.
Your system detects the outage and switches to battery automatically. Lights, Wi-Fi, fridges and security keep running, and solar keeps charging the battery during the day.
Powerwall 3 is a single 13.5 kWh unit with the solar inverter built in (see the Powerwall page). SigenStor is modular (see the Sigenergy page), so you can start small and add batteries or a DC EV charger later. We recommend one after measuring your usage.
Yes. We prepare the SSEG application for your municipality, install to ECSA and SAPVIA PV GreenCard standards, and issue a Certificate of Compliance when the installation is complete.
Yes. Powerwall 3 expands to four units, and SigenStor stacks grow one module at a time. We size the wiring and space for expansion on day one.
We are based in Riverhorse, Durban, and install across greater Durban and KwaZulu-Natal. Larger commercial projects can go further; ask us.
