Buying Guide: Propane Tanks For Generators
What size should I choose? Consider your generator’s run-time needs and your storage space. Smaller tanks (20–30 lb) are easy to move but require frequent refills. Medium tanks (40 lb) balance storage and run-time. Large tanks (60–100 lb) offer longer outages and are better suited for backup systems that sit idle for long periods.
What features matter most? Look for an overflowing protection device (OPD) valve as a safety baseline. DOT and Transport Canada certifications indicate transport safety standards. A powder-coated exterior helps resist rust in outdoor setups. For larger installations, a multi-valve setup can simplify on-site refilling.
Should I pick POL or Type 1 fittings? POL valves are common on larger, stationary installations and require compatible hoses and regulators. Type 1 valves are typically easier to fill and widely used in consumer tanks. Ensure your generator’s regulator matches the valve type on the tank.
Is on-site refilling important? If you run a home generator during outages and want to minimize downtime, a tank with an integrated multi-valve system or a larger capacity can be advantageous. If you plan to transport propane often, ensure the tank’s size is manageable for your vehicle and local regulations.
What about safety and maintenance? Regular inspection of the valve, collar, and exterior coating helps prevent leaks and corrosion. Ensure the tank is X-ray and hydrostatic tested according to local requirements, and store it upright on a stable surface away from heat sources.
FAQ
