Does a disconnect need to be installed with the EVENFLOW?

Short answer, no. The EVENFLOW is rated for a 50amp load and per the 2020 NEC, disconnects only need to be installed on circuits that are greater than 60amps. "Section 625.43 Disconnecting Means. For equipment rated more than 60 amperes or more than 150 volts to ground, the disconnecting means shall be provided and installed in a readily accessible location. The disconnecting means shall be lockable open in accoradance with 110.25."

Do the existing wires need to be upgraded?

Generally the answer is no, existing wires are perfectly fine... Since you're installing a charging station sub-circuit that matches (or is less than) the volt/amp rating of the existing load, it is typically not necessary to upgrade the wiring since only one of the two loads will ever be drawing current at any given moment. (You will obviously need to install new wiring from the EVENFLOW to the charging station.) Online Voltage Drop Calculator Tool

Will I need to upgrade or replace the existing circuit breaker?

If, by code, the existing circuit breaker is appropriately rated (voltage, amperage, and protections like GFCI, AFI, etc.) to handle each load (only one is on at any given moment), then you should not need to upgrade the breaker. That said, some electricians will install a -- stand-alone breaker -- between the EVENFLOW and the charging station if the customer is planning to use a charger that plugs into a NEMA outlet.

Who can install the EVENFLOW?

The EVENFLOW needs to be installed by a licensed eletrician.

What does the 2020 National Electric Code have to say about the EVENFLOW?

The 2020 NEC makes specific mention of technologies like this. "Section 625.42 Rating... Where an automatic load management system is used, the maximum equipment load on a service and feeder shall be the maximum load permitted by the automatic load management system."

Will I need to install a junction box to make connections to the EVENFLOW?

Maybe... If you can install the EVENFLOW near the service panel or the existing load then no, just run a new bit of wire from the EVENFLOW to the panel or the existing load. If the EVENFLOW needs to be installed somewhere away from both the panel and the existing load then yes, just install the junction box somewhere along the existing wiring run and then run a new bit of wire from the j-box to the EVENFLOW. ...

Which vehicles and charging stations will the EVENFLOW work with?

While there are too many vehicles and charging stations to answer this question definitively, the answer is simple, ask the manufacturer what happens when there is a power outage while a user is charging his/her vehicle. We are simply reproducing that scenerio whenever the owner uses his/her dryer, oven, etc.

What tools are required to install the EVENFLOW?

  • #2 Phillips screwdriver with 4" shank

EV Owners

How many miles of range will a EVENFLOW integrated circuit add to my EV battery in 8 hours?

This answer varies from vehicle to vehicle, as well as how much voltage and amperage your charger has available. Based on our experience having installed level 2 electric vehicle charging stations for the last 5 years before inventing the EVENFLOW: EVENFLOW is sharing a 50amp 240volt circuit breaker with an electric oven, 8 hours should add about 200 miles of driving range EVENFLOW is sharing a 40amp 240volt circuit breaker with an electric range, 8 hours should add about 160 miles of driving range EVENFLOW is sharing a 30amp 240volt circuit breaker with an electric clothes dryer, 8 hours should add about 120 miles of driving range

What is the warranty and return policy on the EVENFLOW? How do you handle returns?

The EVENFLOW's warranty is 3 years from the date of manufacture. If a return is necessary, EVENFLOW will take a pre-authorization on a credit card towards the purchase of a new EVENFLOW and send out a replacement same day. As soon as the defective unit is returned to us and we have an opportunity to inspect it. At our discretion, we will judge if the unit was properly installed and/or subject to abuse. If we judge the unit to have been faulty upon leaving our facility, we will cancel the pre-authorization. We also offer a 30 day money back guarantee on any unopened product, simply send us a return request and we will send you a confirmation and instructions to return the product to us within 30 days of the date it left our facilities and we will happily offer you a full refund.

Who is the typical Evenflow Energy customer? Who can install the EVENFLOW?

The EVENFLOW needs to be installed by a licensed electrician. Generally speaking, our customers are the electricians that have been hired to install the charging station. During the professional assessment of the building, the electrician will decide if the existing service does or does not have enough capacity to add the 240 volt charging station. If he/she determines that it does not, the electrician may suggest a complete upgrade of the entire electrical service or perhaps installing the EVENFLOW as a more cost effective solution if it is sensible to do so. As stated elsewhere on this website, the EVENFLOW can also be used to minimize the installation of new wiring through finished walls and ceilings. During the electrician's assesment, he/she may notice you happen to have a large load like an electric clothes dryer near a potential location for the charging station. The electrician may then suggest the installation of the EVENFLOW near the dryer and then just a short run of wiring from the dryer to the charging station, saving your walls and ceilings from the installation of heavy wiring.

What does the EVENFLOW do exactly?

For all the work we put into designing this product, at the end of the day, it is really quite simple... The EVENFLOW Energy Router allows large electric loads to share the same circuit breaker by creating a sub-circuit for the EV charging station and directing power exclusively to the load/circuit that needs it at any given time. Since only one of the two loads/circuits wired to the EVENFLOW can be on at any given time, the service panel and circuit breaker are completely unaffected by the addition of the new EV charging station sub-circuit and load.

How long will the EVENFLOW last?

The EVENFLOW has a 3 year limited warranty. That said, we built the EVENFLOW with industrial grade components to last for years (if not decades) but if you have a problem we'll work with you to make it right.

Can the EVENFLOW work with any of my existing large electric loads?

The EVENFLOW will work to monitor current on any existing 240 volt load (up to 50 amps) that you prioitize and will control any new secondary load you want installed (like an EV charging station). Keep in mind, the new circuit will only be active when the existing circuit is not. When deciding which circuit you want to share with your new EV charging circuit, you will want to select a circuit that is not typically used continuously through the day/night. An example of a circuit that might be problematic to integrate with the EVENFLOW might be some of the newer AC condensers that are designed to run continuously at lower levels to create a more constant temperature and humidity level. While this may provide optimum comfort, it is also a very expensive and energy intense way to run your AC (and arguably not great for the environment). With some adjustments and updates, such systems are typically able to run with a more traditional on/off cycle. Seeing that the EVENFLOW functions by only allowing the EV charging station to run when your prioritized existing load is off, the existing load needs to be completely off for the charging station to work. Basically, when choosing a load to share with your charging station, choose a load that is used the least.

Can I use the EVENFLOW for 110/120 volt charging?

Not today, but we will have a 110/120 volt compatible device in the near future.

Is the EVENFLOW Energy Router listed?

Yes, the EVENFLOW Energy Router is an ETL Listed product and complies with all appropriate UL standards.

Will the EVENFLOW work with my electrical vehicle/charging station?

The answer is simple, ask the manufacturer of the vehicle and/or charging station, "What happens if there is a power outage while I am charging my vehicle?" As we are essentially just reproducing that scenerio whenever you use your dryer, oven, etc., you'll have your answer.
