Solar System Installation Planning

[carlyai]

Initially planning will see the solar setup on and in the garage.

This is mainly about extending the 3 phase supply to and from the garage, picking a suitable place to install the equipment and batteries.

Installing an EV 3 phase charger.

 

Picture 1.

The 3 phase (4 wire?) will run from the house wall, along the pool fence (using unistruts) for the 8 cables (4 for 3 phase in and 4 for 3 phase out).

 

Picture 2.

The existing 3 phase from the grid comes in in the grey painted conduit, 3 phase underground to the house and single phase underground to the garage.

 

SORRY A FUNERAL HERE AT THE MOMENT SO HAVE TO STOP THIS. TBC.

The power cables run along the fence using unistrut fastners. That's maybe 8 25mm2 cables. Cables go into the garage and into a Consumer Unit just to terminate the cable run. 

What I really want is to install a 3 phase EV charger now, but then extending the cables into the garage to the rooms where the second (from right) or 3rd from right windows are to install the inverter/s and batteries.

The garage wall to terminate the incoming cables and install my EV charger.

I really didn't want to break the cables here but allow enough length to get to the solar installation then loop back to the EV charger. This is a bit impractical so what's the best way to do what I want?

The EV charger should happen yesterday but the solar will be in a few month time.

The cabled for the solar installation will be attached to the garage side wall then go across to the other wall for the inverter/battery installation OR into the next room, the store room, as would be more secure and able to install a small air-conditioning as it gets very hot in the garage and just read about 30 degrees C max.  for batteries.

This could be a solar install area.

 

Picture 8

 

This store room would be a better place for the solar setup but first I would remove a lot of the shelfing and move to the garage area.

 

So what do you think?

My main worry is what to use (a 64A breaker?) to terminate the incoming 4 wire cables but be able to extend them easily, but in the mean time just connect up a 3 phase EV charger. (I have one phase to the garage already so I thought to buy a 3 phase charger that can use 1 or 3 phases and initially use 1 phase charger for EV.) 

I used to EV down to 22% battery remaining the other day and taken 2 to 3 days with the small car supplied charger to get up to 100%.
