# Legend for Diary

**Voltage Abbreviations**

**ML** :: Morning Low ~ The reading before sunrise and any use

**DL** :: Daily Low ~ Addition to ML if use drops volts below ML

**Ft** :: Float level reached ~ thought this is adjustable

**Ab** :: Absorption level reached ~ again adjustable ~ see Rolls Guide

**Bk** :: Uncontrolled charging until Ab

---

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)
