Have a look for a pair of "power distribution posts".
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
5x 2.4kWh Pylontech batteries (12kWh)
LuxPower inverter/charger

(Artist formally known as ******, well it should be obvious enough to those for whom such things are important.)

Cheers Stinsy...

Had a look but they don't seem like they are compatible with the connections/leads I have.

Are they not the standard SurLok connectors pretty much all battery packs have these days?

In any case it looks like you have some leads supplied, therefore you want to crimp an M10 or M12 lug and use a power distribution post. Or even just whack 3 cables (one form each battery and one to the inverter) through compression glands into an enclosure (eg Whiska box) crimp a lug on them and bolt them together...

I'm not sure of the problem!

The leads have the correct connector on one end and a lug on the other. If you can bolt 2x lugs onto the inverter then you're golden. If the inverter has some kind of cable management that prevents this then do as I said above...

Thanks Stinsy...

Will leave it to the spark to have a look when they get round to installing in a couple of weeks.

But I was correct in thinking that ideally there should have been 2 positive and 2 negative connectors on to connect the batteries in parallel?

That'd do it (obviously you need two...)
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
5x 2.4kWh Pylontech batteries (12kWh)
LuxPower inverter/charger
