    EDITOR’S NOTE: This is a sponsored post from EV charging installation specialist DCC.

    Home charging has many difficulties when it comes to installation in multi-residential homes, but solutions have emerged for the most common issues. Condo charging installations generally get blocked by two major things – an inaccessible panel (like if you live on the 7th...

    My electrical contractor (Peter from Steglitz Power in San Diego) just completed the installation of our electric vehicle charger with a DCC-9.

    This was an incredibly challenging installation, due to a variety of factors: An older multi-unit building with only a 90-Amp breaker for the unit, long distance and many obstacles on the way from electrical room to parking spot, and the requirement not to encroach on the neighboring parking spot.

    Since 90 Amps would not be enough to power the condo under full load and the vehicle charger at the same time, Peter had to get creative. He researched the options, including getting a dedicated meter. He recommended using an intelligent switch called "DCC-9" that routes power to the charger whenever the condo isn't using too much load. This saved us the major hassle, time and money for getting a new meter.

    The install itself brought many challenges, including finding the right spot in the storage room to mount the DCC-9, and the aforementioned water and drain pipes that were near the path of the conduit route approved by the HOA. Peter worked diligently around all the constraints, and made it happen!

    Thanks to the DCC-9 and Peter's hard work, our place (called "Bluhaus") is now the first Vacation Rental in San Diego's Pacific Beach area that has an electric vehicle charger.

    Hi IchDochNicht,

    How's the DCC charging working out for you and your customers? Well, I hope!

    Have you ever had the DCC stop charging an EV because you're using all the electricity in the condo? If so, did the EV automatically resume charging once your condo usage drops, or was manual intervention required to restart the charging? Wondering if a Tesla would be able to handle this seamlessly...

    Thanks!

    I have not had a lot of opportunity to test it out. So far it didn't have to cut power to the charger.

    However, I do know that it will switch back power to the charger when the power usage in the condo drops below the threshold. I don't remember, if it's 5 or 15 minutes, but it is automatic. Nobody has to go to the box and fiddle with fuses or the like.
