Hi Alan No bulging or heat or sulphur as far as I can tell. Batteries are about 4 years I think... Andy

No - nice thought but sadly no solar! Baffling. Giving all the input and a nights sleep my guess so far is it's either the batteries not telling the unit to stop charging or it's a fault on the charger.

Thanks chaps. I've got 4 x 6V 232A us2200 leisure batteries. Combi pro setting is 6 - open lead acid. So that's correct. Fast charge measured at 14.8V and it's now on trickle at 13.2V which seems ok. According to the led lights and a beep as described in the two page instructions it means 'overcharge' - as above I've no idea what this actually means! Can't easily measure current but suspect this might be it as can't see what else it could be. As suggested will call Sterling Power on Monday to see if they have any suggestions. Thanks everyone for the input so far - the mystery continues!! Andy

Thanks - What do you think it should be kicking out on trickle charge? The sterling combi always goes into fast charge mode on switching on and steps down to trickle but can't find anything online about what voltage I should be expecting...

Been struggling with my inverter charger! Alarm came on and sparse instructions say led panel light combination means Overcharge. Checked batteries and they were low on fluid. Topped them up and seemed ok for a day then alarm again. Batteries low on fluid again. Seems to my simple mind that the combi is overcharging and boiling the batteries dry but could it be the batteries? This unit was a replacement for a Victron unit that died. Both before I owned the boat. Grateful for any advice!

Boy you have to love these forums (or is it forii) Lots of really good advice here. I wasn't thinking of using for heating - more for ventilation and heat distribution. My lovely stove gets the lounge area really warm (sometimes too hot) so a system that trickle pumped warm air to the colder areas and helped ventilate looked interesting. Wondered if lack of usage of MHVR systems on canal boats was down to something I'd missed or just not a big enough benefit. Looking like maybe the latter but jury is still out!

Thanks for prompt replies! Good point on the battery drain. I'm on shore power when not on the move so maybe less of a problem. There's lots of info on these systems - mainly designed for house ventilation - one of many sites online with info http://www.greenwood.co.uk/range/5/heat-recovery-mvhr.html

A year into boat ownership (loving it) and researching heating and condensation. Has anyone fitted a MVHR heat recovery system? Like this - https://www.ebay.co.uk/itm/251159375045. A 20W trickle fan sucks warm damp air out and transfers up to 80% of the heat to incoming fresh air. A few holes and some flat trunking could suck damp & hot stove, cooking and showering air from living and bathroom and pump warm fresh air into bedrooms on my 57' x 10' liveaboard. Circulating warm fresh air and removing damp air. Feeling I'm missing something as it seems all too easy!!
