Here is my issue. I have a detached garage that solar was installed on years ago. My issue is the solar company didn't install a 100amp service as they were supposed to, it only has a 30 amp main breaker. This is not enough power to run things like a dust collector (3HP motor) and table saw at the same time. As it will be very expensive to have a new feed wire run to the garage, and I have plenty or unused room on the flat roof for more solar, I was considering an off grid system to power the garage and charge my car. Based on what I have read, two - EG4 6000XPs and a couple batteries would support the load. My question is: Where I have a 30 amp feed that I can also bring into the off grid inverter, will a single inverter likely be enough when combined with the existing feed? Or does "Passthrough" just mean if external power is available it uses just that?
