Common Q&A

Q: How to install it?

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

Q: Why does 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 charge, it will re-output when the battery will return to 12.6V.

Q: What battery type is this controller supported?

A:B01= OPEN B02= AGM B03= GEL. The regulator is only suitable for lead-acid batteries, not for nickel hydride, lithium, ions, or other batteries. Let the children keep far away from the storage battery and the controller.


<1> Wire Range: 26-12 AWG

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

<3> Old batteries may be degraded capacity after hundreds of cycles, easily dropping lower than 8V, which results in the controller will be shut off (LCD screen becoming 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 a cool and well-ventilated place to maintain good heat dissipation
