Solar All in 1 Lithium Version 3 - N1,030,000
A 12.8V 300Ah lithium (LiFePO4) battery, paired with a 3kVA (approx. 2400W–3000W) off-grid inverter, provides roughly 3,840 Watt-hours (Wh) of total energy. Due to the high efficiency and deep discharge capabilities of lithium, this setup is excellent for powering medium-sized residential or office loads.
1. Typical Household/Office Capability
A 3kVA system can comfortably handle the following simultaneously:
Lights: 10–15 LED bulbs.
Fans: 3–5 ceiling fans.
Appliances: 1 Standard Fridge/Freezer (inverter model preferred).
Electronics: 1 LED TV, 1 Decoder, Wi-Fi Router.
Work Tools: 1 Laptop and 2–3 phone chargers.
2. Estimated Runtimes (Battery Only)
Moderate Load (approx. 500W): (e.g., Fridge, lights, TV, fans). The battery will last roughly 6–7 hours.
High Load (approx. 1000W): (e.g., Added blender/small microwave). The battery will last roughly 3–3.5 hours.
Critical Load (approx. 150W): (e.g., Only lights, router, and phone charging). The battery can last 15–20 hours.
3. What It Can Power Intermittently (Short Duration)
Washing Machine: (Up to 1200W).
Microwave/Toaster: (Up to 1500W).
Small Pumping Machine: (0.5 HP, intermittent use).
4. What It CANNOT Power (Or Should Avoid)
Large Air Conditioners: (1.5HP+ inverter ACs might work on low, but traditional ACs will trip the 3kVA inverter).
Electric Water Heaters/Geysers: (Typically >3000W).
Electric Oven/Hot Plates: (Typically >2000W).
Key Considerations for 12.8V/300Ah + 3kVA
Battery Management System (BMS): Ensure the battery has a built-in 200A+ BMS to handle the high current requirements of a 3000W load.
Efficiency: A 12.8V system running a 3kVA inverter will draw high amperage, making thick, secure cabling crucial to avoid overheating.
Solar Supplement: If this system is in a solar setup, 800W–1200W of solar panels are recommended to recharge the 300Ah battery within one day.
