When it comes to selecting an inverter for residential purposes, the best approach is to identify which appliances you want to run during a power failure. Instead of overspending on high-capacity systems, choosing the most affordable inverter and battery based on actual requirements ensures optimal performance and long-term savings.

Powertech Controls helps homeowners in Chennai select the right inverter and battery combination that balances cost, backup time, and reliability.

How to Choose the Right Inverter for Your Home

Inverter selection depends mainly on:

• Number of lights and fans

• Important appliances you wish to use during power cuts

• Duration of backup required

The capacity of an inverter is usually mentioned in:

• VA (Volt Ampere) or

• KVA (Kilo Volt Ampere)

Whereas battery capacity is specified in:

• Ah (Ampere Hour)

Understanding the Difference

• If you want to run more appliances simultaneously, you need a higher VA inverter

• If you want to run the same appliances for longer hours, you need a higher Ah battery

Ideal Inverter Setup for a Typical Home

For most residential applications, especially a double-bedroom house, the following setup is more than sufficient:

• 1050VA inverter

• 150Ah lead acid tubular battery

This configuration can support:

• Up to 5 lights

• Up to 5 fans

If the connected load exceeds this limit, the inverter will trip automatically, indicating an overload condition and protecting the system.

Backup Time Depends on Power Consumption

The more power you draw from the battery during a power failure:

• The faster the battery discharges

• The shorter the backup duration

Efficient usage during outages running only essential appliances—helps extend backup time significantly.

How to Calculate Watts from VA

To calculate usable wattage from inverter VA:

Watts = VA × 0.8

This helps determine how many appliances your inverter can safely support.

Appliance Wattage Reference Table

Add the total wattage of appliances you wish to run and compare it with the inverter’s watt capacity to select the right model.

Battery Maintenance Tips for Long Life

Tubular batteries require minor periodic maintenance:

• Short Tubular Battery

  • Fill distilled water every 3–4 months

• Tall Tubular Battery

  • Fill distilled water every 6 months

Why Is This Required?

During charging and discharging:

• Acid inside the battery vaporizes

• This causes electrolyte level to drop

• Acid fumes may corrode terminals and lugs

Preventive Measure

• Apply petroleum jelly on terminals and lugs

• This prevents corrosion and ensures proper connectivity
