Your inverter is the brain of your solar system — it converts DC power from your panels and batteries into AC power for your appliances. Choosing the wrong inverter can leave you with inadequate power, wasted solar energy, or premature equipment failure.
Understanding kVA Ratings
The kVA (kilovolt-ampere) rating tells you how much power the inverter can deliver simultaneously:
- 3.5kVA: Lights, fans, TV, fridge, phone chargers. Good for 2-bedroom flats.
- 5kVA: All of the above plus AC (1HP), washing machine, microwave. Ideal for 3-bedroom homes.
- 10kVA: Multiple AC units, water heater, heavy appliances. Built for duplexes.
- 15kVA+: Commercial-grade. For offices, shops, and businesses.
Key Features to Look For
- Hybrid Capability: Can work with solar, battery, AND grid power simultaneously.
- MPPT Charge Controllers: More MPPT channels = better solar harvest. Look for 2+ channels.
- WiFi Monitoring: Check system performance remotely from your phone.
- Pure Sine Wave Output: Essential for sensitive electronics like computers and medical equipment.
- IP65 Rating: Weather protection for outdoor installation.
