chilligibbon Posted February 3, 2015 Report Share Posted February 3, 2015 I have just had a 3 panel kit delivered, each panel has a + and - cable and connector attached, I also have 2 loose cables with connectors 1 end and bare the other to go into controller. Unless I am missing something I cannot work out how the panels will all link together. Ideas please!!!! Link to comment Share on other sites More sharing options...
EEng Posted February 3, 2015 Report Share Posted February 3, 2015 (edited) The panels will (probably be series) So Panel 1 + goes to Panel 2 - Then Panel 2 + goes to Panel 3 - Now you have Panel 1- and Panel 3 + left - These are the +'ve and -'ve of the series array These 2 will go to your charge / inverter etc ? This will be the other 2 cables you have with only one connector on each end The Pos(+) and Neg (-) on each panel if MC3 or MC4 connectors will be male / females so you shouldn't get these wrong PS I'm taking a calculated guess as i don't really know what 3 panel kit you have.......

chilligibbon Posted February 3, 2015 Author Report Share Posted February 3, 2015 Thanks EEng that makes perfect sense now. The kit is a midsummer energy 390w set up but came with no instruction at all on how to wire (series or parallel). Bring on the weekend and I'll try ang get them fitted..

rogeriko Posted February 3, 2015 Report Share Posted February 3, 2015 Is this the kit http://midsummerenergy.co.uk/buy/solar-panel-kits/Sunrise_130W_Tripple.html If so EEng is right the panels all go in series. Dont forget to connect the controller to the battery first so it can detect your battery voltage and then connect the solar panels afterwards. Make sure you get the positives and negatives correct check everything twice before the final connection. Link to comment Share on other sites More sharing options...
Loafer Posted February 3, 2015 Report Share Posted February 3, 2015 Watch it. Series solar panels could apply a voltage beyond the controller's maximum. Check the manual! Link to comment Share on other sites More sharing options...
rogeriko Posted February 3, 2015 Report Share Posted February 3, 2015 Panels are max 30v each. Controller has 150v max input. No problem with that. Link to comment Share on other sites More sharing options...
matty40s Posted February 3, 2015 Report Share Posted February 3, 2015 Just be careful. The Tracer in the picture is the smaller model, not a 30A one. There are also 2 versions of the Tracer 30A - one at 100V max and one at 150V max. The cables, if fitted with mc4 connectors, will be impossible to wire together incorrectly - however, you do need to know which end is which when connecting to the controller.

Thanks Rogeriko, that is the kit, did some reading on series/parallel and voltages last night and understand a bit better now! Link to comment Share on other sites More sharing options...

Hi Matty, the controller supplied is 30amp/150v so all looks good to go. Just need the sun to shine now! Link to comment Share on other sites More sharing options...
Phil Ambrose Posted February 4, 2015 Report Share Posted February 4, 2015 Don't we all. Phil You will get something out of your panels even in this weather but when the sun shines and you look at your gauges you will get the warm glow that comes from free leccy.

chilligibbon Posted February 4, 2015 Author Report Share Posted February 4, 2015 Hi Phil, I have a small 85w panel that performs well so can't wait to see how the new ones help. Link to comment Share on other sites More sharing options...
