Marc from Marlboro, NJ has been a Green Sun Energy Services client since November of 2024. The charger went in that December: a hardwired ChargePoint Level 2 unit rated 11.5 kW, mounted outdoors on a dedicated 60-amp circuit within ten feet of the breaker box. The service measurement came back with 153 amps of spare capacity, which is generous enough that the 60-amp circuit could be added without touching the panel – the check that decides whether an EV charger is a morning’s work or the start of a service upgrade. A utility rebate application was filed and closed as part of the job, which is the sort of paperwork that gets left undone once the installer has driven away.

EV charger questions from Marlboro homeowners
Does a 200-amp service in Marlboro automatically have room for a 48-amp charger?
No. The rating on the service is not the same thing as the capacity left in it. The existing loads decide: electric heat, air conditioning, an electric range, a dryer, a water heater, a pool, a hot tub, solar equipment and anything else substantial all count against what is available. A load calculation answers the question; the number on the panel does not.
Should the highest-amperage charger always be installed?
No. The right charging rate balances daily driving, what the vehicle can accept, the capacity available in the electrical system and what the installation involves. Upgrading a service purely to gain a few more miles of range per hour is rarely the sensible trade.
What is a ChargePoint Home Flex?
A Wi-Fi connected Level 2 residential charger with an adjustable output. Current Home Flex equipment can be configured for 16, 24, 32, 40, 48 or 50 amps depending on how it is installed, which is what makes it useful on a house whose electrical service cannot support the highest setting.
