3️⃣ Quick FAQ

• Inverter size should be ≥ total running watts + 20–30% margin.

• Battery Ah = (Wh × days) ÷ (Voltage × DoD). Example: 2000 Wh → ≈ 104 Ah @ 24 V (lithium).

• Panels ≈ (Wh ÷ sun hours ÷ 0.75). Add 20–25% for losses.

💡 Frequently Asked Questions (FAQ)

What size inverter do I need for my home?
The inverter size depends on the total power (watts) of the appliances you want to run at once. Add up the wattage of all devices, then add 20–30% for safety. Example: If your total load is 1,800 W, you’ll need at least a 2.5 kW inverter. For whole-house backup, most South African homes use 3 kW, 5 kW, or 8 kW inverters.
Can I run my fridge or TV during load-shedding?
Yes — a properly sized inverter with enough battery capacity can easily run your fridge, TV, lights, and Wi-Fi during load-shedding. For a small system, choose at least a 1 kW inverter. For larger setups with multiple fridges and appliances, go for 3 kW – 5 kW or more.
How long will my inverter last during load-shedding?
Backup time depends on your battery capacity and the total load. For example, a 3 kWh battery can run roughly 600 W of appliances for 5 hours. To extend runtime, reduce the number of devices in use or upgrade to a larger battery bank.
What is the difference between a hybrid and a normal inverter?
A hybrid inverter can charge batteries from both solar panels and the grid, giving you the flexibility to store energy for later use. A standard (non-hybrid) inverter usually converts DC power from batteries only and cannot manage solar charging directly. Hybrid models are more efficient and ideal for full solar systems.
Can I add solar panels later to my inverter system?
Absolutely! If you choose a hybrid inverter, you can start with a battery-only setup and add solar panels later. Make sure your inverter has a built-in MPPT solar charge controller or solar input ports for future expansion.
What size battery do I need for my inverter?
Battery size depends on how many hours you want backup power. Use this rule of thumb:
🔹 Battery Ah = (Load Watts × hours) ÷ (Voltage × DoD).
Example: 800 W for 5 hours on a 24 V lithium system (DoD 0.8) → 208 Ah battery. Try our X Solar Calculator for quick estimates.
Do I need an electrician or can I install it myself?
For small plug-and-play inverters (under 1 kW), you can install them yourself. For hybrid or solar-integrated systems, a certified installer is recommended to ensure safety, correct wiring, and warranty coverage.
How do I know which inverter brand is best?
Trusted inverter brands in South Africa include Sunsynk, Growatt, Deye, Kodak, and LuxPower. X Solar stocks these reputable models — all with local support and warranties. The best inverter for you depends on your power needs and budget.
Can an inverter power my whole house?
Yes — with the right system size. For example, an 8 kW inverter with a large lithium battery bank can power lights, TVs, fridges, and most appliances. High-draw items like ovens, geysers, and pool pumps may need to stay on the grid or be run separately.
Where can I buy reliable inverters in South Africa?
You can order online from X Solar — your trusted supplier for solar panels, batteries, and inverters. We offer fast nationwide delivery, secure payments, and expert support from our technical team.
