Common Q&A

Q: How to install it?

A: (1)Battery --->(2)Solar panels ---> (3)DC load

Q: Why the LCD screen become blank?

A: When the battery voltage is too low, the controller will stop to output(≦ 8V, controller turns itself off, LCD is blank, ≦ 10.7V, 12V output ports are not available); after the solar panels charging, it will re-output when the battery will return to 12.6V.

Q: What battery type is this controller supported?

A: (1)B-01=LEAD-ACID, 12V; B-02=LITHIUM ION 3s, 3*3.7V=11.1V; B03=LIFePO4 4s, 4*3.2V=12.8V. (B01 is the default type, If you would like to to switch to another 2 types, please select it manually.)

Note:

<1> Wire Range: 26-12 AWG

<2> Make sure the voltage of your battery reach 11V for initial use , so as to start up for the controller to registered the battery type accordingly.

<3> Old batteries may be degraded the capacity after hundereds of cycles, easily drop lower than 8V, which results in the controller will be shut off (LCD screen become totally “DEAD”).

<4> Indoor use only: the working temperature of this controller is -35°C to +60°C. During hot sunny days, the temperature outside might go up to 60-75°C. Please do keep the controller stay in cool and well-ventilated place to maintain good heat dissipation
