Hi All, I am getting mixed messages regarding solar panels not connected to a drain (i.e. a source to dump power ) is there any body here that can shed light ? I discovered my panels got disconnected ? Not sure how or why, my question is are my panels no good now ? I have heard rumours that if a solar panel is not connected then they will be no good after. I am struggling to find any thing to back this up via the web, any body have personal experience ? I found out yesterday PM, removed panels and stored in boat, ordered an new pre terminated cable. Just hoping panels are not screwed.

Hi All, We have a fairly simple solar controller set up; Victron Energy Blue Solar PWM 20a 12-24v Dual Battery solar controller which doesn't offer much in the way of solar management, display etc. The control panel for this is more or less the same price as the controller itself. Ideally i would like to up grade the controller system to allow for a better visual and more efficient use of my solar. Can anyone recommend a good controller system that could be put in place of the Solar dual?

Hi all, We currently have 3 x 125ah leisure batteries powering the fridge, lighting (mostly LED) and water/waste pumps. The bank is charged by a single solar panel through an EPSolar MPPT charge controller. This was fine during the summer but with winter fast approaching we are finding that come the morning there isn't enough juice to power the pumps for a shower. We are mostly marina based so would like to add in a mains charger to top up the batteries once night falls. Electricity is metered so would only want to charge from shore power when necessary. Currently we achieve this by attaching a car battery charger using crocodile clips - it works but isn't a viable long term solution. The charger only has trickle or fast charge and is manually selected. I was also a little wary that I might be sending current to the solar panel instead of away from it, but it hasn't blown up yet So, my questions are: Is there such a device available that I can connect both the solar and a 240V charger to and it automatically selects which input to charge the batteries with, prioritising the solar? Maybe even with automatic health programming to allow the batteries to discharge periodically to keep them healthy? Failing that, if I just get a decent 240V charger that automatically switches charge mode, will there be any problems permanently connecting that directly to the batteries in addition to the solar, and just turn it on when required? Or should I connect them via, say, a rocker switch to manually change from solar charging or 240V charging? What fuses would be required? Can someone recommend a decent multistage 240V charger? I'm sure I'll think of something else as soon as I've posted this, but it will do for starters :-) Thanks in advance.

Hi all, I'm just about to purchase two of these solar panels and was wondering whether anyone had any experience with mounting something similar on their roof and was able to recommend where best to get screw-down / secure mounts? I had a search through old posts and, while many discuss various options for securing solar panels or discuss building their own frames, no-one seems to have mentioned actually purchasing frames from a given site and how they found the experience of installing it (unless I missed a post somewhere). Thanks as ever for any thoughts or experience. Ryan
