Trying things in the poly tunnel, my first winter. Broccoli was looking great, until the mice found them, despite 6 traps. The spinach hanging in there. First broad beans in small pots high above the mice were doing well until the shelf slipped and they fell onto the floor and the mice had them. pea...

Sounds familiar! I too am from a sailing background since the 1960's, mostly on classic yachts. The Sylvia was a 1927 120ft ketch that had 2 enormous banks of singe cell batteries wired in series to 120 volts d.c. Everything on board was 120 volts DC, including the anchor windlass! Most of the yacht...

Bit of a dilemma ere, was thinking about lithium, but it seems hard to get them sorted for a 24 v system. mine are basically a yachtie version that I am familiar with bigger batteries than we had on the yachts. Had gel and AGM, but that was sometime ago. Looks as if these lithiums need a load of mon...

Wow, I thought my 40 kw wood gasification boiler was hard work to keep going!#

Yes, they are in series. They are big batteries, 1156 AH each battery, connected by thick wires. They don't work too hard, we draw about 4 kwh a day. max draw is 1 kw from the washing machine and max charge from the panels or generator is 70 amps 24v dc.

Indeed I do, and to be honest, the end batteries do not seem to drink more water than the others. Maybe I don't have to disconnect and turn around. here's hoping!

ok, will do thanks.

I have 4 Rolls 500 batteries in series. They are 11 years old, and apart from being a bit thirsty, still do the job. J read somewhere that it is a good idea to end to end them occasionally. I never have, partly because they way a ton and not brilliantly accessible. Any ideas?
Thanks,

Mike

Interestingly, slightly related, a large solar installation near Yarmouth (IOW) has suffered a major degradation of it's panels. I was talking with the farmer yesterday and he said that although they were past the guarantee date, the Chinese company is replacing them as it would be bad publicity for...
