1 Production Instructions Thank you for choosing the Pstar Series of Solar Power Controllers. The controller uses numerical control technology design, LCD display, automatic operation. Its pulse-width modulation (PWM) type battery charging mode, as well as control technology, will greatly extend the battery life. This controller is suitable for the solar energy system (independent system), control the charging and discharging process automatically.
1.1 Features ⚫ Integrated charge presets Integrated charge presets combined with adaptive charge logic are well suited for most common battery types, such as LiFePO4, Gel and flooded lead-acid. ⚫ Flexible Application Automatic identification of 12V/24V/36V/48V system voltage. ⚫ Multi-stage charge algorithm The multi-stage charge algorithm is specifically engineered to optimise each recharge cycle and charge maintenance over extended periods.
2 Installation and Connection 2.1 Unpacking and Inspection Before unpacking the controller, check whether the package is damaged. After unpacking, check whether the contents of the package are damaged or missing. You should have received the following items inside of package: ⚫...
d. Install the controller in a location where it is protected from environmental conditions such as water, high moisture and dust, and also located well away from any flammable liquids or gasses. e. DO NOT install or place/operate the controller on top of the battery, directly above the battery, or in a sealed compartment with the battery;...
Note: The voltage in series shall not exceed maximum PV input open-circuit voltage. ➢ Recommended wire diameter and breaker type for DC output (DC load side): Model Max. DC output Current Wire Diameter Circuit Breaker Spec Pstar-30A 10AWG 2P-20A Pstar-60A 8AWG 2P-35A...
2.6 Wiring Precautions a. Let installation and connection work be done by a licensed electrician. b. To avoid short circuit and reverse polarity connection, ensure that the positive cable is connected to the positive polarity port (+) of the device, and the negative cable is connected to the negative polarity port (-) of the device.
2.7 Installation and Connection Step-By-Step 1. Mark the position of the mounting spots on the wall based on the mount holes of the controller. Then make 4 mounting holes in the wall with an electric drill according to the spots. Refer to the "...

5. PV Connection: Connect the PV array to the controller with the cables. 6. DC Output Connection: Connect the load to the controller with the cables. 7. Check before starting up: See figure as shown below for wiring details. If everything is all right, and all the wires are firmly connected, close the circuit breakers at the battery side, PV module side, and load side in sequence to startup controller.
3 Operation Mode 3.1 Charge Algorithm The battery charging controller is equipped with an intelligent 3-stage charge characteristic which takes care of an optimal charge of your batteries. When switched on, the Pstar Controller always starts at Bulk stage. 30mins There are 3 integrated charge modes (Bulk, boost, float).
Any setting made are stored and will not be lost when the controller is disconnected from battery or PV module. The multi-stage charge algorithm includes the individual charge stages described below: ➢ Bulk charge: The battery is charged at maximum charge current until the voltage increases to the configured boost charging voltage.
Function Keys To switch the PV input parameters information/ Return the previous option. To switch the charging information/ Enter the next option. To adjust DC output mode and DC output operation duration/ Confirm and reserve the settings. 4.2 Browse and Configuration Parameter Step-By-Step After cables are connected and the device is started, perform the initial configuration according to the following steps based on the actual situation.
