Is Erus Energy Still in Business?

No. Despite some outdated online listings that may still show Erus Energy as open, Erus Energy ceased business operations and filed for Chapter 7 bankruptcy in November 2023.

Erus Builders LLC and Erus Holdings LLC, which operated as Erus Energy, filed Chapter 7 petitions on November 8, 2023.

Erus was headquartered at:

21402 N 7th Ave
Phoenix, AZ 85027

The company also operated from other locations, including Tempe and Tucson, and installed residential solar systems throughout Arizona and other states.

That leaves an obvious question for former customers:

Having an Erus Energy Solar System Doesn’t Mean You’re Stuck

One of the most common misconceptions after a solar installer closes is that nobody else can touch the system. That's generally not true. Your solar system is made up of standard electrical and solar equipment that can be inspected, diagnosed, repaired, and, when necessary, replaced by a qualified contractor. Depending on when and how your Erus Energy system was installed, it may contain equipment from major manufacturers such as:

An Erus system may include:

  • Solar panels
  • Inverter or microinverters
  • Power optimizers
  • Solar wiring
  • Breakers
  • Disconnects
  • Conduit
  • Grounding
  • Monitoring equipment
  • Electrical service equipment

If one part fails, the entire system may appear to be dead.

Our job is to find out which part.

My Erus Energy Solar Panels Aren't Working. What Should I Do?

Start with diagnosis, not replacement. Solar panels are only one component of the system. When production drops to zero, homeowners understandably assume something is wrong with the panels. Quite often, the problem is somewhere else.

Potential causes include:

  • Failed inverter equipment
  • Microinverter or optimizer problems
  • Electrical faults
  • Damaged solar wiring
  • Loose or high-resistance connections
  • Tripped breakers
  • Disconnect problems
  • Ground faults
  • Monitoring or communication failures
  • Damaged modules
  • Utility-related issues

That’s why Watt Masters approaches solar repair from an electrician’s perspective.
Test the system. Find the failure. Then decide what actually needs to be repaired.

Erus Monitoring Is Offline. Does That Mean My Solar Stopped Working?

Erus Monitoring Is Offline. Does That Mean My Solar Stopped Working?

Not necessarily. There are two separate questions:
Is your solar system producing electricity? and
Can your monitoring system communicate with it?
A communications failure can make a working system appear offline.
On the other hand, losing monitoring can also be the first sign of an inverter or electrical problem.
Instead of guessing, the system should be checked to determine whether you’re dealing with a monitoring issue, an equipment failure, or both.

Erus Energy Warranty Problems After Bankruptcy

Homeowners often worry about losing warranties after Erus Energy’s bankruptcy. Understanding the difference between installer and manufacturer coverage is key:

1. Erus Workmanship Warranties

  • Installer-backed warranties (labor, roof penetrations) were affected by Chapter 7 bankruptcy.

  • Watt Masters does not assume Erus Energy’s contractual warranties.

2. Manufacturer Equipment Warranties

  • Equipment (panels, inverters, microinverters, optimizers, batteries) usually carries separate manufacturer warranties.

  • Coverage depends on the equipment brand, model, and cause of failure.

  • Solar panels
  • Inverters
  • Microinverters
  • Power optimizers
  • Batteries
  • Other equipment

Is Your Failed Inverter Still Covered?

Possibly. An installer’s bankruptcy doesn’t void hardware manufacturer warranties. We diagnose the failure so you can determine if active manufacturer coverage remains without replacing the entire system.

Frequently Asked Questions About Erus Energy Solar Repair

Solar System Not Producing

If your Erus system stopped generating electricity, we can troubleshoot the solar and electrical components to identify the likely source.


Inverter Faults

An inverter fault may involve the inverter itself or another part of the system. Proper testing helps distinguish between them.

Low Solar Production

Your system doesn't need to be completely offline to have a problem. A sudden or unexplained production drop may indicate an equipment, module, electrical, or communications issue.

Monitoring Problems

If your monitoring disappeared, we can help determine whether the issue is communications or actual lost production.

Solar Electrical Problems

Solar is electrical infrastructure.
Loose or damaged connections, failed breakers, damaged conduit, grounding issues, disconnect problems, and other electrical faults require an electrician who understands photovoltaic systems.

Unfinished Erus Installations

If Erus closed before your project was operational, we can evaluate the existing solar and electrical equipment and help identify technical issues that remain.

Existing System Inspection

Bought the home after Erus installed the solar? We can evaluate an existing system even if you weren't the original customer.
