**ML** :: Morning Low ~ The reading before sunrise.
If there is no overnight use this is an indication of battery charge and is the parameter for setting the length of time the next Absorption charge will run.
The morning low I record is the lowest voltage recorded once a new 'day; begins. a) this isn't at midnight I have noted and b) the voltage will rise once the load is disconected, so the data I extract isn't soemtimes a close value :(
**DL** :: Daily Low ~ The minimum voltage the battery reaches during a 24 hour period of use from sunrise. Unless the batteries are unused and assuming there is some sun to maintain charge then this figure will be lower than ML
**Ft** :: Float level reached ~ though this is adjustable
**Ab** :: Absorption level reached ~ again adjustable ~ see Rolls Guide
**Bk** :: Uncontrolled charging until Absorption reached
Fallback from Ft > Ab and/or Ab > Bk hasn't yet been determined ?? TO DO!!!!
V is Volts:: A is Amps :: W or KW |is watts or kilowatts: (**W = V × A**)
Y is total daily yield from panels including use and storage etc. in Wh or KWh (watt or kilowatt hours)
