Marybeth from Freehold, NJ has been a Green Sun Energy Services client since September of 2024. The charger went in on 26 November: a hardwired ChargePoint Level 2 unit rated 11.5 kW on a dedicated 60-amp circuit, with the load calculation putting the minimum service at 133 amps. A service upgrade followed in February – the supply taken underground and up to 200 amps with a new forty-space panel. That is the other answer when a load calculation comes back above what a panel can carry: load management holds a charger inside an existing service, and upgrading the service removes the constraint altogether. Which one suits depends on the house, and it is a question worth settling before the charger is ordered rather than after.

EV charger questions from Freehold homeowners
Does a 200-amp service in Freehold 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.
Can home charging be scheduled?
Yes. Both ChargePoint Home Flex and Tesla Wall Connector connect to their manufacturer's app and support scheduling and monitoring, which lets charging be moved into whatever off-peak window the utility rate offers. The same connection carries firmware updates and diagnostics.
Does the receptacle behind a plug-in charger matter?
It does. A receptacle carrying a high current for hours every night takes far more thermal stress than one used occasionally for an appliance, so it needs to be a device suitable for that duty and correctly installed. This is a large part of why hardwiring is often preferred for a permanent installation.
