I have a 980Ah lead/acid batterie bank , 12x2V, tubular special solar
They are now 10 years old and have not been used correctly over the last
year, voltage without charge had dropped to 2V per element,
I have tried to discharge them to 1,85V per element,
so as to start a correct charge to REVIVE them,
So at this moment they are being charged by 1080Watts solar
DIRECT/ meaning without regulation, as to give them a BOOST
and mix the acid due to bubbling !!
I had hoped to see the voltage go to say 30Volts as it is a 24V system,
but now after 3 days of full sun the voltage does not exceed 29.2V
Not bad but is this sufficient?
I suppose 1080 parted by 24 will give 45Amps max!
which is 5% of the batterie bank ?
These batteries are in good condition ,,,
what would you propose? your opinion ?
PS this is not my boat system but my homestead!
