Description
A 3kW (3000 Watt) Complete Inverter System is a compact, entry-level power solution that comes with a 2.56kwh lithium battery storage for small homes, apartments, or offices. It is ideal for users looking to maintain “essential” power during outages. The system consumption and output can easily be monitored on a mobile smart phone since it comes with a data logger.
This 3KW Backup System (Unit-Only) is a high-capacity “UPS-style” solution designed to keep your home or office running during power outages.1 Unlike the solar package, this system charges directly from the utility grid or a generator.
Because there are no panels to “refill” the battery during the day, your runtime depends entirely on your load:
| Total Load | Example Appliances | Backup Time |
| 150W (Light) | 10 LED Bulbs, WiFi, 55″ TV, Laptops | ~15–17 Hours |
| 350W (Medium) | Lights, TV, WiFi, 2 Fans, 1 Fridge | ~6–7 Hours |
| 800W (Heavy) | Lights, TV, Fridge, + 1 Desktop PC/Small Pump | ~2.5–3 Hours |
⚡ Backup Performance (How long will it last?)
⚠️ Important Usage Tip
Without solar panels, the system relies entirely on the grid to charge. If you have very long blackouts (e.g., 20 hours a day), the battery may not have enough time to charge fully between outages. In such cases, adding even 2 solar panels later is highly recommended.
Because there are no panels to “refill” the battery during the day, your runtime depends entirely on your load:
| Total Load | Example Appliances | Backup Time |
| 150W (Light) | 10 LED Bulbs, WiFi, 55″ TV, Laptops | ~8–12 hours |
| 350W (Medium) | Lights, TV, WiFi, 2 Fans, 1 Fridge | ~6 Hours |
| 800W (Heavy) | Lights, TV, Fridge, + 1 Desktop PC/Small Pump | ~2.5–3 Hours |
