Sigenergy has become one of the most popular premium choices for homes in Cape Town and Gauteng, and the question we hear most is simple: which size do I need? To make that easier, we've put our installed Sigenergy packages on one page with indicative prices. Here's how to read them and pick a starting point before we design your system.
What Comes in Every Package
Each package is a complete installed system: a Sigenergy hybrid inverter, a Sigenergy battery and solar panels. The price ranges include VAT, installation, certification and council registration, so there are no hidden extras for the paperwork. You can see all of them on our Sigenergy page.

Step 1: Single-Phase or 3-Phase?
Start with your home's electrical supply. If your home is single-phase, the 6kW, 8kW and 10kW packages are the ones to look at. If your home has a 3-phase supply, the 15kW and 30kW packages are built for it. Not sure which you have? We confirm it when we assess your home.
Step 2: Inverter Size Is About Your Peak Load
The inverter size (the kW number in each package name) sets how much you can run at the same time. A smaller home that mainly needs lights, fridge, Wi-Fi and TV through an outage sits comfortably at the lower end. Bigger homes running a pool pump, geyser, oven and air-conditioning together need more inverter headroom.
Step 3: Battery Size Is About How Long You Last
Where two packages share an inverter size (the small ¹ and ² in the name), the second one adds more battery and more solar. More battery keeps you going longer through the night and through outages, and more solar refills it faster and lifts your savings.
