Determining Your Power Requirements
Before selecting an inverter and battery, accurately assess your power needs. List all essential appliances you'll run during a power outage. Consider the wattage of each appliance; this information is usually found on a label on the appliance itself. Summing up the wattage of all appliances provides your total power requirement.
For instance, running a refrigerator (150W), a TV (100W), four lights (50W each), and two BLDC fans (50W each) results in a 450W requirement. Remember that inverters operate at around 70-80% efficiency. Therefore, you'll need a slightly higher inverter capacity than your total wattage requirement.
Choosing the Right Inverter
To determine the inverter's VA (volt-ampere) rating, account for the inverter's efficiency. Divide your total power requirement (in Watts) by 0.7 (or 0.8 for a more conservative estimate). This calculation gives you the minimum VA rating needed.
If your calculated requirement is 643 VA, choose an inverter with a rating higher than this (e.g., 600 VA or higher). Inverters come in various capacities (600 VA to 2500 VA), allowing flexibility based on your budget and requirements. Always opt for an inverter with a slightly higher VA rating than your calculated minimum.
Selecting the Appropriate Battery
Battery selection hinges on your power requirement and the desired runtime. Multiply your power requirement (in Watts) by the number of hours you need the inverter to run. Divide the result by 12 (assuming a 12V battery). This calculation gives you the minimum Amp-hour (Ah) rating needed.
For a 450W requirement running for 4 hours, you'd need at least a 150Ah battery. Select a battery with a higher Ah rating for added runtime and to extend its lifespan. The market offers various options ranging from 135Ah to 260Ah; select a battery based on your needs and the inverter's compatibility. For higher capacity needs, consider a dual-battery setup. Note that some inverters have maximum battery compatibility limits
Inverter Features and Considerations
Several advanced features can enhance your inverter's performance and safety. Solar compatibility allows for integration with solar panels, maximizing energy efficiency. A bypass switch provides uninterrupted power during inverter maintenance or malfunction. App-based control allows for remote monitoring and optimized usage.
Safety features are crucial, including short-circuit, overload, over-temperature, and low-battery voltage protection. Most inverters are compatible with various battery brands, offering flexibility in your choices. Factor in warranty periods (typically 2-3 years) and pricing when making your final decision.
Product Recommendations and Conclusion
The video provides recommendations across various usage levels (basic, medium, high). For basic use (lights, fans, fridge), 800 VA inverters suffice with a single battery. Microte Super Power 700 and VGA Prime 750 are suggested. For medium usage (additional TV, computer), 800-1200 VA inverters with single batteries are recommended, like Luminous Zelop Plus 1100 or LiveGuard options.
High usage (including AC) requires 2500+ VA inverters with dual batteries; Luminous Zold 1700 and Luminous I Cruise 3000 are highlighted. Solar compatibility and lithium-ion battery options (Genus Maxi Lion) are also discussed. The final recommendation emphasizes considering individual needs and requirements when making a choice, ensuring the best balance of features, capacity and budget.
