Well finally it’s done. We completed installing the solar panel this morning. It seems to working fine but will need to go to anchor to check. In the end I’m glad we employed a local sparky to finish off the installation as we didn’t have enough MC4 connectors. He managed to salvage 2 from a double to single y piece connector and the also use soldier to make sure of the connection. I had all the cables (6mm2) ready including the one through the arch. It took him 90 minutes to complete the job. We feel €100 well spent. That’s us with a single 315w panel, 4 x 142aH house batteries, 1 x 110aH starter battery all connect through a Votronic humidity specific MPPT. We plan to buy a double induction hob in August when we are home for a few weeks. No 3kw inverter yet until we get used to what we have. The tv one is only 300w. Ian how big is your TV to be 300W ? should be more like 30W my 24" TV with BlueRay and 4T disk with movies consumes about 4amps when all is ON and all to MAX. for example this one is only 48W with DVD etc... www.bauhn.co.uk/_literature_156074/ATV24C-1116_BAUHN_24inch_Full_HD_LED_TV_with_DVD_Player_-_Instruction_Manual

Vasko, 62”. No only 21”. The inverter was already on the boat when we bought it. I guess it was part of the commissioning in 2008. Ian

Ian Glad you have it sorted, our twin system with the same LG 315 and votronic mppt is working really well too 😁 we have been sailing quite a bit in last week and with admittily quite a bit of sun is keeping the batteries at 100 percent even with fridge, autopilot and my quite powerful hungry E80 plotter on for hours. I was a bit worried I might have cooked the mppt when I connected it. I covered the panel with thick sunbrella then with the mppt fuse removed I connected the positive wires then then the negative, battery one last, then inserted the fuse, there was an audible spark, but all seems well. Sure there is a better way of doing this which perhaps our resident sparkies could advise?

The way to connect the mpp should be described in the manual of the mppt ... to be honest I followed the manual some times some times I do not I usually connect the battery first next tbe panels... I do not cover the panes etc.. and so far all has been good ... If your panes are in series and the voltage is high - this may have been the reason for the spark...

Ian Then you are quoiting the inverter power - e.g. 300W this is not the actual consumption my guess is that you TV should still consume about 70W including the loss inside the inverter...

Malcolm, The sparky here made up the connections to the panel first and then checked there was power at the battery end of the cable before making any connection to the MPPT or batteries. Having seen power was passing through the cable he disconnected the connections at the panel. He never covered the panel. With the connections at the panel disconnected he made all the connection adjacent to the battery box - MPPT, fuses, MPPT to house batteries and the engine start battery, temperature connection. All very methodical. Once these were made he then reconnnected the connections at the panel. Ian

2 x 140W I think. German (can't remember make). Can remember they were very not cheap. Replacement for old knackered panels and needed new regulator to enable full juice to flow.
Hello. I’m planing to install a panel on the same location as you hav. Did you have to remove the panel covering the lines to get the cables inside the boat, or how did you do it? Thanks in advance! Regards Martin

This is on a Jeanneau 41DS I installed 4 100wtt panels on the frame. Then took them off to place the canvas back on and put the panels over the canvas. My goal was to make the panels invisible and low profile as if it did not exist. Abe
