Buying Guide: Diesel-Related Considerations and Standby Power Decisions
- Fuel type: Diesel, natural gas, and propane each have operational pros. Diesel standbys are common for mobility or specific sites, but many home standby models rely on natural gas or propane for convenience and reliability. Consider fuel availability and conversion feasibility for your home setup.
- Generator size: Match unit wattage to your essential loads. A too-small unit may trip off more often; a too-large unit adds upfront cost and unnecessary fuel use.
- Transfer switch capacity: Ensure the transfer switch can handle the planned load. A 100 Amp transfer switch supports many homes, but larger residences may need 200 Amp or higher.
- Connectivity: Mobile Link or similar monitoring helps track status and maintenance. Decide if cellular or Wi-Fi connectivity fits your monitoring preferences and budget.
- Installation considerations: A licensed professional should assess the electrical system, fuel lines, and outdoor clearances. Check local codes and permit requirements.
- Maintenance and warranty: Look for a clear warranty term and maintenance plan. Regular service intervals preserve reliability during storms and outages.
