A

B

  • BM - battery monitor
  • BTU - British Thermal Units, a measurement of heat.

C

D

E

  • endAmps - the amount manufacturer-specified amount of measured current in Amps that signals the end of the Absorption stage of charging.

F

G

I

  • Imp - current (I) the panel puts out at Vmp. Vmp X Imp = Pmax
  • IRL - in real life; in practical terms
  • Isc - max current (I) the panel can output. This occurs when the panel wires are short circuited.

L

  • LFP - LiFePO4 lithium batteries

M

P

  • Pmax - maximum power the panel can output
  • PT - part time (ie, lives in a vehicle part time)

S

T

  • TLA - three letter acronym =)
  • Toad - a second vehicle which is towed
  • TT - travel trailer
  • TV - tow vehicle, usually a pickup truck

V

  • Vabs - Voltage setpoint for the Absorption stage of charging.
  • Vfloat - Voltage setpoint for the Float stage of charging.
  • Vmp - Voltage at which a solar panel produces maximum power under present conditions.
  • Voc - Maximum Voltage the solar panel can output. This occurs in an open circuit condition1)
  • VSR - Voltage Sensing Regulator, a smart kind of battery isolator

W

  • WM - walmart
