New member, and looking forward to contributing and currently looking for advice.

I’m having PV and battery installed next week, 16 panels 8 east, 8 west @ 450w per panel, 6kw inverter, @ 1 x EP11 10kw battery.

Have a Zappi EV charger installed on Octopus IOG, my concern and it’s not totally answered yet by the installing company, is not drawing from the battery to charge the car, PHEV 14kw, when Octopus decides to charge, which can be in the 6 hour cheap window or anytime they have cheap electric to sell.

So can someone advise if the current setup can be used to hide the load on the house from the battery.

Currently the Zappi CT clamp is across the whole house load on the i/c live tail from the DNO fuse.
The supply cables after the meter for the whole house supply and EV charger is into a Henley block, tails then feed to the house CU and the Zappi CU.
The breakers for the inverter will be installed in the house CU as there are spare bays available, so if the CT clamps for the Fox system are on the house CU side of the Henley block, will this hide the load of the Zappi charger and not draw from the solar battery ?

Diag attached

Many thanks in advance for any advice.

Hi and welcome.

That’s actually quite a straight forward install of your EV charger, the Zappi CT clamp can stay where it is and as long as the inverters CT clamp is fitted between the Henley block and the consumer unit on the live feed it won’t see the load from your EV charging.

Many thanks for the prompt reply and advice

Gut feeling was that was the case, but seemed too simple to be correct
