Planning off-grid 240V 25A EV charge system with EG4 6000XP inverter and EG4 PowerPro 14.3 kWh battery in my house garage. My house is built on riprap (boulders to raise it above a flood plain) which I cannot drive an 8 foot grounding rod into.
Nearby is a steel garage on concrete pad - I attached a 25 foot long bare copper wire 4AWG as a ufer ground to the steel for concrete underground before the concrete was poured
Question is how to earn-ground the planned EV charging electrical panel in my house garage.
Can I run a copper wire 4-6AWG to the steel garage ufer ground.
Code states that a grounding conductor cannot exceed 20 feet in length and should preferably be shorter. The run to the steel garage would exceed the 20 foot minimum.
Any suggestions would be welcome.
