The wife asked what the space was for above the batteries and I just said oh that’s like and expansion slot for later, she stared at me quite a lot and then walked away.
I think I may have gotten away with that

there’s actually space for two more 3000c’s each battery sits on its own full length angle brackets so no loading of battery below.
I will go and connect them all together after tea and add the coms and earths just to advance things a bit further along. Electrician is due back after Easter to power up the cabinet change the consumer box and a host of other jobs.
