Page 5: General Information
General Information The RENOGY MPPT series controller is suitable for off-grid solar applications. It protects the battery from being over-charged by the solar modules and over-discharged by the loads. The controller features a smart tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery. - Page 6 The current does not come out of thin air. Instead, the power generated in the solar panels is the same power that is transmitted into the battery bank. Power is the product of Voltage (V) x Amperage (A). Therefore, assuming 100% efficiency: Power In = Power Out Volts In * Amps In = Volts out * Amps out Although MPPT controllers are not 100% efficient, they are very close at about 92-95%...
- Page 7 Four Charging Stages The MPPT charge controllers have a 4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization. Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar power to recharge the battery and is equivalent to constant current.

Page 13: Operation
Mounting Recommendations WARNING: Never install the controller in a sealed enclosure with flooded batteries. Gas can accumulate and there is a risk of explosion. 1. Choose Mounting Location—place the controller on a vertical surface protected from direct sunlight, high temperatures, and water. Make sure there is good ventilation. -
Page 14: Load Work Mode Setting
NOTE: In order to adjust a parameter go to your desired LED indicator, hold the orange set button for a little over 5 seconds. Wait until the number inside the Work Mode display flashes. You are now in parameter setting mode and can continually press the orange set button and cycle through the numbers until the desired number is reached. - Page 15 The MPPT Charge Controller is equipped with a programmable dual timer function for the load terminal. Depending on the user setting, the timer(s)’ purpose is to turn on/off the load for a selected amount of time during the day, during the night, or manually to the user’s discretion.
- Page 16 voltage goes above point of DTTV (Day Time Threshold Voltage). The controller will recognize the voltage increase and undergo a 10 minute delay before turning off the load terminal. If Timer 1 has already been set to a time frame before night time is over, then Timer 2 will be able control the amount of hours the load turns on again before reaching the DTTV.
