1. Product Introduction 1.3 Exterior and Interfaces 1.1 Product Overview ① ② ◆ This controller can charge the battery most efficiently by dynamically loading the panel to deliver its maximum power ③ even during rapidly changing conditions, and monitoring the State Of Charge (SoC) of the battery. It is designed to ④ function as the primary control unit in an off-grid photovoltaic system, and to provide an intelligent interface between solar panels, battery, and load.
Compared with conventional PWM controllers, the MPPT controller can make the most of the solar panel's max. power and therefore provide larger charging current. Generally speaking, the latter can raise the energy utilization ratio by 1.5 Charging Stages Introduction 15% to 20% in contrast with the former. As one of the charging stages, MPPT can not be used alone, but has to be used together with boost charging, floating charging, equalizing charging, etc. to complete charging the battery.
layer and burn surrounding materials, and even cause a fire, therefore make sure all connections are tightened securely. >Equalizing charging Wires had better be fixed properly with ties, and when needs arise to move things, avoid wire swaying so as to keep Warning: risk of explosion! In equalizing charging, an open lead-acid battery can produce explosive gas, therefore the battery chamber shall have connections from loosening. good ventilation conditions.
Step 1: choose the installation site ① Connecting to external temperature sampling interface Do not install the controller at a place that is subject to direct sunlight, high temperature or water intrusion, ② Connecting communication cable ③ Connecting power cable and make sure the ambient environment is well ventilated.
ERROR indicator: 3. Product Operation and Display 3.1 LED Indicators PV array indicator Indicating the controller's current charging mode. BAT indicator Indicating the battery's current state. LOAD indicator Indicating the loads' On/ Off and state. ERROR indicator Indicating whether the controller is functioning normally.
3.3.1 Startup interface Mode No. 0 1~14 Descriptions When no sunlight is present, the solar panel voltage is lower than the light control on voltage, and after a time delay, the controller will switch on the Sole light control load; when sunlight emerges, the solar panel voltage will become higher (nighttime on and daytime off) than the light control off voltage, and after a time delay, the controller will switch off the load.
After entering into the setting interface, tap the Set key to switch the menu for setting, and tap the Up or Down key to increase or decrease the parameter value in the menu. Then tap the Return key to exit (without saving parameter setting), or press and hold the Set key to save setting and exit. When the controller temperature exceeds the set value, it will decrease the charging power or halt charging.
