Solar PV + battery - do I need a diverter?

@Robert.Wall

But we know @ben.jones12 can’t do this because of the topology

Perhaps it is possible (if the Tesla Gateway uses a c.t.) to combine that c.t. with another around the dump load spur as you suggest here

@Robert.Wall

If you are using genuine current-output c.t’s, then connecting them in parallel results in the currents adding (or of course subtracting if you reverse one of them - either with the direction of the primary (the cable) or with the secondary connections). If they are the voltage output type, then wiring in series will have the same effect. Both c.t’s must have the same sensitivity, or you’ll need to be inventive and you might need an additional burden for one of them, the aim being to make them appear to have the same sensitivity at seen at the input to your inverter.

We know that Ben has some twisted pairs in CAT6 cable available to extend c.t.s between garage and house.
