Hi llkhanse

It is an iSocket - just google that - I for the environment version - which also does temperature, water in the bilge and gas alerts. Cracking bit of kit.

Hi S&J

I went for an 80W panel from Off Grid - and a Victron controller - installed it last week - really pleased. 

I am getting 2A overcast and 4.8A under clear sunny skies. The Victron controller is great - especially with the iPhone App connected by the VE Direct. 

Really pleased - total cost £340.

Hi everyone, Iím new to this topic but the problems others mentioned are now relevant to me. My boat was new in April 2016, so the batteries have completed 3 seasons and 3000 miles. Fitted a Solara solar on roof hatch garage same as others from new, never abused batteries but now starting to notice the cycle life is a lot less than when new. Approximately 10 hrs sailing with fridge and autohelm and they are low., even with a charge from engine for 30 mins or so they wonít last a night at anchor without the low volt alarm sounding (12.2 volts). I Was thinking of adding another 120w of solar on coach roof, to increase to 200w overall, but wonder should I save my cash and just replace the 2 x 165ah AGM batteries.

Hi Adrian,
 
12.2 V means that your battery bank has been 50% discharged. I assume that you have the standard 330 Ah battery bank with two AGM's.  As stated above your average consumption with AP, instruments and fridge is max  7-8 Amps ( mine varies between 5 and 9 Amps peak with and without fridge ). The conclusion is that your battery bank is "sick", maybe caused by a total discharge at one time.
You can install new batteries ( about 800 Ä ) or give it a try with a a Novitec Megapulser which they market as a battery refresher for 85 Ä ( www.conrad.om ). Be aware that opinions about the latter are mixed, some think it is the greatest thing since sliced bread, others call it battery voodoo.
 
We had these gadgets in the military to keep the batteries fresh when permanently connected to a charger in the army depot. I had such a thing on my last boat for standard gel batteries.
 
Good Luck!

The MegaPulse is intriguing!  It appears to get good reviews on svb24 where there is also a marine version which switches on/off at a higher voltage than the standard device.

I would be interested in the views of anyone who has used these with AGM batteries on a Hanse.

After 4 seasons and 7,000 NM I also began to notice degradation in my battery life this season.  I think that extended periods at anchor in the Scandinavian archipelagoes may be a contributory factor.

Update from Mr Blue Sky. Iíve replaced the original Solara solar control pane with a Victron 100/30 MPPT and added an additional 40w panel in front of 80w already fitted to the sliding hatch garage. Both Solara, work well together even in shade and good non-slip surface. Now have max of 120w or 6A, and the Victron gives great real time info, and performance is much improved over the Solara control. Going to fit 2 x new Victron 165ah AGMs in Spring when back to sea level, as too much to lift up whilst in cradle. I intend to monitor my battery performance during 2019 and add further Solar if required, but I hope with the Fridge cut out, new batteries and 120w Iíll be ok, obviously charging frequently in Marina for full boost.

Fendant, My new Victron MPPT has a type of Mega Pulse fitted to help keep batteries in good order, and there are various settings to allow max boost at certain times. However they do not recommend for AGM as this type of battery may suffer if charge exceeded 14.6v. The built in charge boost goes over 15v, so I am reluctant to test it. If at all I could have a stab st it with my old batteries, as nothing to loose there I suppose, just need some sunshine to get the solar pumping!

thx Bluesky,  interesting aspect you rise here. Obviously Victron and Novitec are of different opinion about the use of "megapulsing" AGM's.
