You will not receive the critical ancillary components required for a complete installation. These must be sourced separately and represent a significant additional investment and planning. Required items include a matching automatic transfer switch (ATS) capable of handling 80kW, all necessary wiring and conduit, a substantial concrete pad for mounting, and the fuel source infrastructure (large propane tank with regulator and piping or a dedicated natural gas line). First impressions are of a solid, industrial piece of machinery. The aluminum enclosure feels robust, and the fit and finish are professional. Understanding this is key to evaluating if the Protector Series 80kW pros cons balance out for your project.

How to Use RG08045X Protector Series 80kW Generator: Complete Guide

Step 1: Initial Setup and Installation

Warning: Installation of an 80kW standby generator is not a DIY project. It requires licensed electricians and often a plumber for gas work. The process involves: pouring a level, reinforced concrete pad at least 5 feet from the house (per local code); mounting the 1,890-lb unit; installing the automatic transfer switch next to your main electrical panel; running heavy-gauge wiring in conduit between the ATS and generator; and connecting the fuel supply (a 500-gallon+ propane tank or a dedicated 1-1/4″ natural gas line). Proper permitting and inspection are mandatory. This complexity underscores why you must carefully consider if you should I buy an 80kW generator and have the budget for professional installation.

Step 2: First-Time User Guide

Once installed, your electrician will commission the system. This involves configuring the Evolution controller for your fuel type, setting exercise schedules (recommended weekly for 20 minutes), and testing the automatic transfer sequence. As the owner, your first task is to download the companion mobile app and pair the unit using its cellular connectivity. Familiarize yourself with the controller’s home screen, which displays status, voltage, frequency, and engine hours.

Step 3: Core Functions and Daily Use

In daily use, the generator is designed to be invisible. It will run its automatic self-test. During an outage, the core function is automatic: the controller senses the power loss, starts the engine, commands the ATS to transfer the load, and powers your home. You don’t need to do anything. You can use the app to monitor the outage duration, fuel consumption, and see when utility power returns.

Step 4: Advanced Techniques

Use the Mobile Link app’s “Fleet” feature if you manage multiple properties. You can create custom alarm notifications for specific events (like low oil pressure or high engine temperature). For optimal fuel efficiency during long outages, consider manually shedding non-essential loads via your sub-panels, though with 80kW, this is less critical than with smaller units.

Step 5: Maintenance and Care

Routine maintenance is vital. This includes checking oil levels, changing oil and filters (after the first 50 hours, then every 200 hours or annually), inspecting the battery and terminals, and ensuring the air intake and cooling fins are clear of debris. An annual professional service check is highly advised. For a detailed maintenance schedule, refer to our generator maintenance checklist.

Step 6: Troubleshooting Common Issues

Common alerts include “Low Fuel,” “Battery Not Charging,” or “Overcrank.” The Evolution controller provides fault codes. For low fuel, refill your propane tank or check gas pressure. A battery not charging could mean a failed alternator or bad connection. An “Overcrank” fault often points to a fuel supply issue (closed valve, empty tank) or a starting system problem. Always consult a professional technician for repairs. Having a professional install and service your unit is the best way to ensure that your decision to buy 80kW standby generator pays off in reliability.
