Selecting the right inverter capacity when building a home backup system is crucial. An inverter that is too small will not power the essential appliances you need. A large inverter will be an unnecessary expense.
Inverter capacity is the total power consumption of the devices and the total time the devices are meant to be powered. You should consider the daily power consumption of your devices in the home before you decide on a backup system.
Calculating backup wattage begins with creating a list of appliances that will require power backup and the wattage rating of each.
The example also shows total power consumption of 420W.
A 20-30% safety margin should also be added to future needs and appliance start up loads.
Understanding VA and Watts
Interpreting inverter specs can be challenging for some homeowners because some specifications are in VA (Volt-Amperes) while others are in watts.
VA = Watts ÷ Power Factor
The average household has a power factor close to 0.8.
Therefore, 800 W of power means a power rating of 1000VA is required for the inverter.
800 ÷ 0.8 = 1000VA
Inverter Capacity Based on Home Size
600VA - 1000VA Inverters
For homes that only need backup for lights, fans, routers, and a TV, a 600VA - 1000VA inverter is adequate.
Typically Applies To:
For a home that has several fans, lights, a TV, and a refrigerator, a 1200VA - 2000VA inverter is required.
Typically Applies To:
For homes that have large appliance usage, a 3 kVA inverter is adequate.
Typically Applies To:
For large systems, a professional load assessment is recommended.
An inverter is limited in capability by the battery bank selected.
Even large capacity inverters only provide limited usage of backup power if the bank is small.
Many people only look at inverter size and completely miss battery size, causing backup performance issues.
Power cuts and inconsistent supply are ongoing problems for many people. Short fluctuations in power can impact the function and shorten the lifespan of electrical equipment, especially backup systems.
A mainline stabilizer helps provide a steady supply, before power reaches sensitive appliances and power backup systems.
Benefits include:
A stabilizer is the minimum solution to protect connected equipment for systems designed to run through sustained supply and voltage fluctuations.
Not all systems and products provide the same level of protection, as the quality of the product, the engineering, and the support after the sale can significantly impact the protection.
When looking at stabilizers, consider:
Reliable manufacturers of stabilizers supply protective guidance and support the selection of the stabilizer for the application.
Forgetting Future Needs
Many people purchase a system based only on present needs. Future purchases of appliances may lead to an overloaded inverter.
Not Accounting for Normal Loads
Some appliances may draw a substantial start-up load that can lead to an overloaded inverter.
Opting for the Cheap Alternative
The quality of some inexpensive options should be considered. Prioritizing long-term performance over short-term costs is critical.
Forgetting About Voltage Protection
Backup systems may be damaged as the result of inconsistent power. A good protection solution is an effective way to minimize that risk.
Ignoring the Need for an Install Specialist
While some tasks can be completed without professional assistance, many complicated installations should be completed with an experienced expert. A great installer can outline the right capacity choice that accurately reflects the true consumption.
Selecting the right size inverter begins with the way power is used in the home. For reliability, total load plus future estimates, and an appropriate battery solution are essential. A system that delivers the desired performance will utilize the right sized inverter solution.
Safeguarding equipment from inconsistent power should also be a concern. The combination of a suitably sized inverter solution and an adequate protection solution results in an effective and dependable electrical system for everyday consumption.
