Even if you purchase a smaller generator, you can prioritize what you power with Power Relay Modules (PRM). During a power outage, your entire house is connected to generator power, but PRMs cycle some circuits on and off to prevent overloading.
Helps your generator balance high electrical loads

Can manage up to four additional loads using a separate relay in each module
