Does a 100-amp Gladstone service have room?
We run a load calculation against your existing service first. A 100-amp panel already carrying a heat pump or an electric range may not have the capacity for a charger, and there a load-management device or a service upgrade is the honest answer rather than an overloaded panel. A Gladstone panel upgrade runs $2,500 to $7,500 if it's needed. Our Gladstone panel upgrade page covers it, and doing both at once is usually cheaper than two trips.
