I am using MRTG to monitor a charge controller at a remote site. I can graph the voltage of the solar panels and the battery bank.
It nicely displays the maximum, average and current values for the period of the graph.
I am not very interested in knowing the maximum value of the battery voltage at night because it won't ever be higher than it is at sunset. I would like to see the minimum voltage for the overnight period. That would help me decide if more or fewer batteries are needed to store the power.

The configuration is as follows:
MaxBytes[PacketFluxVoltage]: 1375000
Options[PacketFluxVoltage]: growright, gauge, nobanner, absolute, noarrow
Title[PacketFluxVoltage]: Battery V*100(10) and Solar Volts(11)
YLegend[PacketFluxVoltage]: Volts)
YTics[PacketFluxVoltage]: 5
YTicsFactor[PacketFluxVoltage]: 0.1
Factor[PacketFluxVoltage]: 0.01
ShortLegend[PacketFluxVoltage]: Volts

Legend1[PacketFluxVoltage]: Battery Volts
Legend2[PacketFluxVoltage]: Solar Volts
LegendI[PacketFluxVoltage]: Battery
LegendO[PacketFluxVoltage]: Solar
