Emporia makes a load balancing charger. You hook an anmeter around the mains and it can pull anything less than the max the box can handle. My 200 service was also "full" but when monitoring the energy, we rarely pull above 40 amps. We'd only hit 200 if the emergency heat was running at max for both HVACs, the oven was on, the water heater was going and the dryer was running. Pretty hard to do by accident, nigh impossible if you think about it
