Overview This manual describes how to use the QRPworks SolMate solar charge controller. SolMate is a flexible solar charge controller that can charge a variety of battery technologies. SolMate features include: The ability to charge your battery at the same time the battery is being used to run your rig.
Caution: Make sure you use the proper cable for the battery to be charged. Using the incorrect cable could result in damage to the battery, battery fire or explosion. SolMate is not designed to charge batteries that do not have a built-in Battery Management System (BMS). Batteries with a SolMate...
Output Use the appropriate SolMate output cable for the battery type to be charged. The cables have programming resistors that select the output voltage as marked on the label. Never use the 14 volt cable to charge a 3 cell Li-Ion 11.1 battery pack or fire will be a likely result.

Theory of Operation At the heart of SolMate is a very efficient DC-DC Power converter which transfers up to 90% of the panel’s energy to the battery. The power converter is controlled by a microprocessor which performs the Maximum Power Point Tracking, collects and tabulates data, and drives the LCD display.
SolMate Specifications Solar Panel Input Solar Panel Range = 5 to 25 Watts STC Rating. Larger panels can be used, but SolMate will use 25 watts max. Input Voltage Range = 10 to 22 volts Optimum input voltage = 14 to 18 volts ...
