Load Test Method
When the Night light mode is ON and push SELECT SW more than
two seconds, the load will turn on. When you release your hand from
SW, the load will turn off. (This method is effective only before the
load turn on in the day time).

6-2 : Early Start Lighting Function
Day Dusk Night
Other controller's night light load ON point
SolarAmp mini early start lighting load ON point
Turn on early
SolarAmp mini has the early start lighting function. The load will start
to turn on from dusk. This function will operate the following day after
insatlling SolarAmp mini at the earliest.
Soon after installing or sudden bad weather, the load will start to turn
on by the condition of PV voltage. The conditions are as described.
(1) Solar voltage will be less than 10V.
(2) After that, solar voltage will be less than 8V.
For this reasons, you will need to wait for more than 3 minutes to start
to light at the night from charging the battery.

SolarAmp mini rate timer is different from a traditional night-light
timer. The lighting time of load is set by a rate (%) of night time. Even
if the night time is changed seasonally, the lighting-off time will be
apporoximately at the same time. There is no need to reset the timer
setting as seasons change.

7. Troubleshooting
7-1 : Lighting ERROR LED
LVD : The battery voltage is low. Please charge with the battery 12.5V or more until
becoming it.
Battery : The cause is as follows.
• Battery is not connected
• Battery is low or too high voltage
• Short-circuited
• Deeply discharged battery cannot charge with recovery
Please check the wire connection and battery voltage for the system.
PV : The PV voltage is lower than battery voltage. This error will remain for about one
minute after PV begins to generate.
There is no problem though this error occurs during the night.
LVD&PV : LVD and the PV error occur at the same time.
7-2 : Battery is not charged
SolarAmp mini charge controller will not charge unless the PV voltage is higher than
battery voltage. It takes approximately 3 minutes to start charging from PV voltage. In
the event of a battery fault the charge controller will not charge. On the other hand, the
charge controller will not charge when battery is fully charged or battery voltage more
than 13V.
7-3 : Load does not operating properly
7-4 : LED does not light
7-5 : Early start lighting function does not operate
Please check LVD status of solar controller. Even If the battery voltage is over 11.5V,
once the controller become LVD, the load will NOT turn on unless the battery voltage
be over 12.5V.
SolarAmp mini automatically turns off LED. LED lights for one minute only when
SELECT SW is pushed.
The Early start lighting function does not operate on that day when the installation rst
day and the setting were changed.
Besides, when it gets dark suddenly by the bad weather, it begins to light detecting
from the power generation of the solar battery as well as an usual controller.
