@Dellmassive top man, you see in that photo above, they have given me a 5m of that black cable to extend the range of the panels to the controller, but I need the opposite. Can I reuse that cable instead and replace it with Anderson connectos and make the extension that way? It looks thinner than one with the crock clips which goes away from the controler? Is panel cable 4mm and battery supply cable 6mm?
the rest of the kit included . . . connection cables with fused crock clips,
carry pouch, and user guide for the controller.
they use MC4 connectors for the PV and battery side . . . which i dont like, so ill be changing that over at some point soon. (anderson plugs for battery side)
power wise . . . . . i plugged it into the Victron 100/30 while testing . . and got 148W (10.6A charge rate into Lifpo4 battery) in late afternoon . . . so very happy with that. =]
Hey, if you're ever looking for Renogy United Kingdom products, let me know and I can get you a discount at Renogy United Kingdom. Here's a coupon if you need one now:
So, just out of interest what is the difference between supplied controller with Lensun and say Victron one like this, is it worth investing into one of these at the later date? Would it work with 100w folding panels that I have?

i would be putting an inline fuse here on that red cable near the red clamp. -
..
why?
well that cable section is long enough to get you into trouble, say it was clamped to the battery under the seat and out the door . . . the door could be slammed shut shorting out the battery to body work via that piece of unfused red cable. - not good.
remember fuse all connections to a battery - ATT the battery.
so safety first - i would add an in line fuse.
something like this will do. a 20A ATC blade fuse, crimped or soldered inline with heatshrink or cloth tape over the join.
Just tested my new system, rather cloudy here in Wales this afternoon. Plugged as advised, crocks onto batt (controler became alive and detected the batt, then plugged panel connector with a connector coming out of the controller, unfolded the panels and it started to slowly charge the battery producing only 1amp as its heavy cloud cover. @Dellmassive i have ordered those extension cable 5m to the batt, also ring terminals for the quick disconnect Anderson conn for the batteries w/t fuse so there will be no need for crocks. I have also ordered that Victron controller as suggested (coming tmrw).
At the end i folded the panels first, discon panel with the controller (and now fun started, I couldn't disconnect MC4 plugs, dear god i couldn't squeeze those clips to the side to unplug it, managed at the end but i can't feel tips of my fingers now then disconnected the crocks from the battery. I wish these MC4 are Anderson plugs as well as they are sooooo much easier to unplug, could these be changed? I think that i have seen on your system that there is Anderson plug from the panel lead and then into the controller?

yes you can technically use Anderson connectors for the PV side. ( thy are rated high enough spec wise) ( the 200w Renogy kit come that way - but ill be changing that soon)
but i like to have different connectors so its impossible to connect up wrongly.
Ie -
solar panels will ONLY connect on the PV side.
and battery connections will ONLY connect on the battery side via the Anderson connectors.
incorrect connections by mistake could be costly.
having Andersons on both sides leaves you a possibility on connecting up backwards - which is very bad.
