Page 9: Additional Components
Additional Components Additional components included in the package: Remote Temperature Sensor: This sensor measures the temperature at the battery and uses this data for very accurate temperature compensation. The sensor is supplied with a 9.8ft cable length that connects to the charge controller. Simply connect the cable and adhere the sensor on top or the side of the battery to record ambient temperature around the battery. -
Page 10: Installation
Installation Recommended tools to have before installation: Screwdriver Multi-Meter Connect battery terminal wires to the charge controller FIRST then connect the WARNING solar panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery. Do not over tighten the screw terminals. This could potentially break CAUTION the piece that holds the wire to the charge controller. -

Therefore, when the user has a solar system whose Vmp is greater than the battery bank voltage, then that potential difference is proportional to the current boost. The voltage generated at the solar module needs to be stepped down to a rate that could charge the battery in a stable fashion by which the amperage is boosted accordingly to the drop.

It uses 100% of available solar power to recharge the battery and is equivalent to constant current.
- Page 22 Equalization: Is carried out every 28 days of the month. It is intentional overcharging of the battery for a controlled period of time. Certain types of batteries benefit from periodic equalizing charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction.
