Buying Guide: Key Purchase Considerations
- Power needs: Match wattage with essential circuits and typical peak loads. If your plan requires running heavy loads, prioritize 12,000+ running watts with a higher surge capacity.
- Fuel options: Tri-Fuel and dual-fuel designs offer flexibility during fuel shortages or price spikes, but expect higher upfront costs and more complex maintenance.
- Starting and operation: Remote electric start, recoil start, and automatic transfer switches impact convenience and install complexity. Consider weatherproofing if you’ll place units outdoors in variable climates.
- Safety features: CO sensors and CO alerts add protection in enclosed spaces; ensure proper ventilation and adherence to local codes for installed systems.
- Maintenance and warranty: Look for extended warranties, available service networks, and included maintenance kits to extend life and minimize downtime.
- Install considerations: Standby systems often require certification and professional installation, especially when integrating with home electrical panels and transfer switches.
- Portability vs. standby: Portable models offer flexibility but less automation, whereas standby units provide automatic transfer and seamless home backup during outages.
