DIY Field Ground Mount Arrays - Multiple Inverters - Battery DC distance - CU Wiring

    Hey all,

    To give you an idea. Assumptions that an RECI would check, certify, NC6 etc.

    Shed in field directly behind house, 35m away from house's consumer unit. ~5Kw Array 1 location's edge (last panel) is about 20m to the left of the shed. ~2Kw Array 2 to the right of the shed would be 30m away from shed.

    Aim is to use the shed as the central mini consumer unit AC junction (AC switches & RCBOs) and then run a single 16sq armored cable between shed and house.

    Q1 - If the array 1 (left) had a hybrid inverter, outside due to 20m from shed, how would a battery setup work? Or would it work well since its going to be 20m distance for DC from inverter to charge the batteries. Alternatively it would mean placing the Hybrid inverter inside the shed and having the + and - tails running 20m from the array to the shed. Is either feasible?

    Q2 - I assume that each AC feed in the shed's CU would have its own sized RCBO. And then another larger rated RCBO in the House CU.

    Q3 - How does Exporting and FIT work with multiple Inverters using one 16sq line to the house's CU?
