Lithium again...

[Bobc]

How do you use your battery? How often does it get to float? What kind of loads are you applying?

I tend to let it get down to about 20-30% before charging it back up to float, so maybe twice a week. Loads are the usual plus electric winches and anchor windlass, and things like a hob and microwave through the inverter.

I think the frequency of recharging makes a difference. Mine get out of synch after a week or so of not hitting float. Big loads every day from electric kettle 2kw, induction hob 2kw, electric stove 2kw, immersion heater 860w, watermaker 2kw.

Mine do the same, the BMS one gets out of sync quicker and more out of synch than the SmartShunt. Charging the batteries resets them both.

Hopefully a somewhat simpler question as my Lithium plan takes shape - any recommendations for a good quality solar panel - around 150 to 200 Watts I would think, to connect to a single 280aH battery ?

I use Photonic Universe panels. Not the cheapest, perhaps, but i would not touch the cheap and nasty end of Ebay crap, where they try to sell you a 200mm square panels as being 3 million watts.

Are you looking for a glass panel or flexible ?

150W Photonic Universe panel at 12V Planet seems to be £97 which seems very reasonable unless I'm somehow misreading it !

Doesn't need to be flexible, although I haven't quite decided yet

Looks fine, couple of quid less than PU

Where are you locating it? I tend to look at the available space and try and find the largest one that will fit. You can't have too much solar.
If you want to cram more Watts in to a given space, look for N type panels that will more efficient but cost more. When I have a width x length in mind, I see what I can find to fit.
We managed to fit new N type panels in the same space where we previously had older P type panels with only a small increase in actual area. They went from 180w to 250w. A significant increase in output plus the new panels are bifacial
