An automatic changeover switch sometimes called an automatic transfer switch, allows switching between two power sources—usually the utility grid and a backup home generator or solar and battery storage system. It detects when the primary power fails and automatically switches to the backup source so there is no interruption to power. 

Key Benefits

Installing an automatic transfer switch provides these key benefits:

Generator Backup Power Systems

When it comes to home generators, almost all of them need an automatic switching device installed next to the main electrical panel. It's wired into critical circuits so when the power cuts out, the switch tells the generator to turn on while disconnecting your house from the neighborhood electrical lines.

Solar and Battery Backup Systems

Many setups have to shut off when the grid is down to prevent backfeeding. Adding batteries and a switch fixes this - it makes your house rely solely on the sun's energy stored in your batteries. This way you can keep the lights on even if it's nighttime or cloudy.

Selecting the Right Changeover Switch

When selecting a transition switch, these key factors must be considered:

•      Application (generator/solar) and home Electrical load
•      Number of amps and voltage rating
•      Enclosure type
•      Single-phase or three-phase power
•      Transition speed
•      Manual operation capability
•      Integrated controller vs external

Our experts at Blades Power Generation can determine the optimal switch specifications and capacity based on your unique home backup system and loads.

Proper Installation Guidelines

To function safely and efficiently, automatic changeover switches must be professionally installed following proper electrical codes and procedures. Our licensed electricians recommend these guidelines:

Locate it close to the main panel

•      Mount securely with adequate clearance
•      Use appropriate wire size to prevent overload
•      Follow all manufacturer mounting and wiring instructions
•      Test operation thoroughly post-installation

Key Wiring Connections

Making the proper electrical connections is critical for automatic transfer switch functionality. Ensure the following circuits are correctly wired according to the installation manual:

•      Utility Power
•      Backup Power Source (Generator/Batteries)
•      Grounding Conductors
•      Main Electrical Panel
•      Control Wiring

Call Blades Power Generation to keep your system operating safely for years to come.

•      Seamless transition to backup power - Prevents lights and appliances from shutting off when transitioning power sources
•      Safety - Isolates the two power sources to prevent back feed accidents
•      Convenience – Operation is fully automated for ease of use even for homeowners without electrical expertise

Two main types of home backup power systems use automatic changeover switches:

1. Generator Systems
2. Solar/Battery Storage Systems

Potential Cost Savings from Buying Used

The most compelling reason many buyers consider used generators for sale in the UK rather than brand-new models is the lower costs. Some key advantages include:

• The purchase price can be 50-70% less than new

• Still, get good output capacity and features for the money

• Good option if you have a limited budget for the project

• Used industrial generators still have many reliable operating hours left

Potential Drawbacks of Used Generators

• Older used generators may be near typical lifespan expectancies if they have seen thousands of operating hours already
• Past owners may have skipped vital upkeep like oil changes and filter replacements, accelerating wear and tear over time
• A higher likelihood of inheriting mechanical issues or part failures sooner rather than later
• More uncertainties around performance versus new models under factory warranty with minimal runtimes

Just be sure to thoroughly inspect condition and maintenance records before purchase.

Tips for Getting Good Value from Used Generators

If you decide purchasing a used generator is the best fit for your needs and budget, here are some tips for getting the best long-term value from that purchase:

•  Inspect thoroughly - Have both an electrical specialist and diesel mechanic evaluate any used generator to spot existing or upcoming issues with the engine, fuel system, control panel, alternator, etc. Make operation inspections standard practice before finalising a purchase.

•  Ask for maintenance records - Get full details on the total operating hours, regular maintenance activities performed, past issues and repairs, etc. This helps give you realistic expectations for usable lifespan and operating costs.

• Purchase from reputable dealers - Buy from trusted generator companies and resellers rather than unknown private parties. This helps avoid poorly maintained equipment or fraudulent condition claims.

•  Consider certified refurbished - Some dealers fully service and restore used generators with genuine OEM parts and include guarantees on operation. These cost more than other used options but represent enhanced reliability.

•  Factor in some capital for near-term repairs/replacements - Be realistic that a used generator likely requires at least some mild servicing soon even if no major issues surface initially. Assume you’ll spend a bit on maintenance items like new fuel injectors, alternator refits, electronics calibration, battery replacement etc. within the first couple years of operation. Factor funds for this into your total purchase budget.
