The 8kWh battery gives flexible backup depending on your combined load:
- ~1.0kW load (e.g., lights + fans + TV + router + laptop): ≈ 8 hours
- ~1.5kW load (adds more fans/laptops or a small freezer): ≈ 5–6 hours
- ~2.0kW load (inverter AC + fridge + lighting + TV): ≈ 4 hours
Single-device guidance:
- LED TV (100W): ~60 hours
- Wi-Fi router (15W): ~405 hours
- Deep freezer (avg ~100W): ~60 hours
- Inverter AC (eco ~450W): ~13.5 hours; Small AC (~600W): ~10 hours; 1.0 ton (~900W): ~6.8 hours
Continuous power capability: The 3.6kW pure sine inverter can run combined loads like 1.5HP AC + fridge + lighting + TV + internet + laptops with headroom for startup surges.
Charging time
- Solar: Unit supports high PV input. With 8 × 550W (4.4kW) in good sun, typical full charge window is about ~2.5–3.7 hours (weather and setup dependent).
- Grid (PHCN): Fast AC charging supported, so you can quickly replenish during outages.
Actual times vary by sun intensity, shading, wiring, and usage while charging.
