Lumin Smart Panel Overview: How It Works And Who It’s For

Key Takeaways

  • The Lumin Smart Panel adds smart control of up to 12 circuits inside your main electrical panel.

  • The Panel is compatible with any electrical panel, and has special integration with home batteries from Tesla, Enphase, and SolarEdge.

  • The cost of the Lumin Smart Panel is between $2,100 and $2,900 before installation, and installation charges range from $1,000 to $1,500.

  • The installation may qualify for a federal tax credit of up to $600.

  • The Lumin Smart Panel is best for homeowners with existing home batteries who want to add smart controls to save money and extend battery life.


Lumin Smart Panel features and functionality 

The Lumin Smart Panel is essentially an automatic circuit breaker with smart app control. It can control up to 12 circuits: 6 for loads that draw up to 60 amps, and 6 for loads of up to 30 amps. 

The Lumin Panel can be installed alongside any main electrical panel and connected to the circuits inside. This differs from something like the SPAN Panel, which completely replaces your existing electrical panel.

Lumin makes two versions of the Smart Panel: one for indoor applications and the other for outdoor applications, which comes with a NEMA 3R-rated cabinet. The Lumin Smart Panel is compatible with any existing electrical panel and takes about 2 hours to install.

You can decide which circuits you want to control, but Lumin recommends never using the Smart Panel to control circuits for smoke detectors, fire suppression, medical devices, or your internet modem and router.

Using the Lumin Smart app, you can manually turn each circuit on and off and set up automatic control of any of the circuits based on the time of day, whether the grid is up or down, or the available capacity of a home solar battery.

In addition to setting automatic times for circuits to turn off, you can also set circuit priorities to turn off higher-draw appliances as available battery capacity decreases in an outage. 

Here’s a bit more on each of the Lumin Smart Panel’s features:

Power outages and battery integration

When the power goes out, your home battery kicks in to keep the lights on, but the battery inverter might not have enough power to run your whole home. 

Lumin offers a special “Smart Power Mode” for these events. Using the Lumin Smart app, you can set a wattage limit that all circuits in the home (even those that the Smart Panel doesn't control) are allowed to draw. You can also set a priority for each circuit the Lumin Panel controls. 

As you use energy within your home during the outage, the Lumin Smart Panel automatically switches off low-priority circuits to keep your power draw under a specific limit and switches them back on again when enough power is available.

The practice of automatically turning off select circuits to prevent too much power from being drawn is called “load shedding.” Here’s a video showing how the Smart Power Mode works:

State of charge integration

As a power outage continues for extended periods, the battery's capacity can decrease rapidly. Lumin offers integration with Enphase, SolarEdge, and Tesla batteries that can automatically determine the “state of charge” or how much energy is left, and shed loads according to a priority you set. 

Here’s a short video showing Lumin’s enhanced state of charge settings:

Time of use rates

Another way the Lumin Smart Panel can help is by saving money under a time of use (TOU) rate plan

Under TOU rate plans, the cost of electricity changes based on the time of day. Energy is generally more expensive in the evening hours, which is when most people return home from work and use appliances, lights, and air conditioning. 

People in Michigan and Missouri have mandatory TOU rates, and anyone who gets solar panels in California must also sign up for a TOU rate plan.

A graphic showing how the cost of electricity changes during the day  and time of year for customers on Southern California Edison's TOU-D-PRIME rate plan. In summer, there are off-peak prices of 25 cents per kWh every day from 9 pm to 4 pm the next day, and on-peak prices from 4 to 9 pm of 61 cents on weekdays and 38 cents on weekends. In winter, prices for weekdays and weekends is the same, with off-peak prices of 23 cents from 9 pm 4 pm the next day, and on-peak prices of 58 cents from 4 to 9 pm.

The Lumin Smart Panel can automatically turn off non-essential circuits for high-powered appliances during these hours. For example, a water heater and upstairs air conditioner can be deactivated during peak times and reactivated after peak hours are over to save electricity.

Demand management

The term “demand response” refers to utility companies limiting grid demand by temporarily controlling their customers' smart devices to reduce demand among a large number of homes. This can be a very effective way to reduce the cost of grid power for all ratepayers. 

Similar to demand response, a virtual power plant (VPP) is an aggregation of many utility customer batteries, which can be activated when the grid needs extra power. 

Often, customers are rewarded for participating in a demand response or VPP program, earning a small amount of money (or a bill credit) for doing so. 

As a connected device that can control circuits within a home, the Lumin Smart Panel can participate in demand response and VPP programs. However, because the device is relatively new to the market, Lumin has not set up participation in any current programs.


Lumin Smart Panel cost and availability

The Lumin Panel is available at retail prices of between $2,100 and $2,900 from sources like NAZ Solar Electric and Signature Solar and can also be purchased directly from one of Lumin’s partner installers. 

Lumin estimates that the installation takes two hours, but installation costs will vary based on the job's complexity, local hourly rates, and the cost of materials and equipment. We estimate the installation cost to be between $1,000 and $1,500, bringing the total cost of the Lumin Smart Panel to between $3,000 and $5,000.

The Lumin Panel may qualify for a tax credit of up to $600 for electrical panel upgrades. According to the IRS, to qualify for the credit, the panel must be “installed in conjunction with, and enable the installation and use of any qualified energy efficiency improvements, or any qualified energy property (such as a heat pump).” Discuss the credit with your tax advisor to ensure you can qualify. 


What problems does the Lumin Smart Panel solve? 

The modern need for reliable electricity has led many people to install solar panels and home solar batteries, so they can have power in the event of an outage. But whole-home backup batteries can be quite expensive, so people tend to choose a battery with smaller capacity and only power essential circuits in their home in the event of an outage. 

This is typically accomplished by connecting the battery to a critical loads panel, which connects to certain circuits inside the home’s main electrical panel to provide power from the battery to only those circuits in an outage. But critical loads panels are rather “dumb,” meaning they must be manually switched on and off. 

The Lumin Smart Panel provides automatic control of key circuits in a home to reduce power draw from non-essential appliances at certain times. The Smart Panel allows homeowners with battery backup to preserve some of their battery capacity and reduce their power consumption during times when the grid is expensive. 

In addition, the rise of time-of-use electric rates has led people to seek out a solution that can deactivate appliances that draw a lot of power during the evening “peak” hours when electricity is the most expensive. People don’t want to have to go to their electrical panel every evening to turn these circuits off and then back on again. 


Pros and cons of the Lumin Smart Panel

The Lumin Smart Panel compares favorably with other smart electrical panels on the market and offers several advantages. However, it also has some drawbacks compared to other options.

  • Allows smart control of home appliances.

  • Saves money on utility bills under TOU rate plans

  • Allows customization of the use of energy stored in a home battery

  • Integrates with batteries from very popular brands: Tesla, Enphase, SolarEdge

  • Relatively inexpensive and easy to retrofit to existing home

Cons
  • Can only control up to 12 circuits in a home

  • Doesn’t offer solar priority (i.e. activating circuits like EV chargers when there is extra solar power available)

  • Doesn’t cost much less than competing products that offer more control


Bottom line: Who should get the Lumin Smart Panel?

In our opinion, you should get the Lumin Panel if all of the following are true:

  • You have a home battery

  • You are on a time-of-use rate plan

  • You want to have manual and automatic circuit-level control via a smart app

  • You have no more than 12 circuits you need control over

  • You have some space on the wall near your main electric panel

  • You can find a great company to install the Lumin Smart Panel

If all of those things are true for you, we recommend the Lumin Smart Panel as a great way to add smart circuit control to your home!
