FAQ
Q1:
Why isn’t charging displayed after my PV panel is connected?
A1:
Check if the PV panel wiring is correct, and if the connection is reversed or
false; check if the PV panel voltage is too high; check if the PV panel is blocked and
the voltage drops consequently.
Q2:
Why is the charge current so small?
A2:
The higher the PV panel power, and the stronger the sunlight, the larger the
charge current, and conversely, incorrect PV panel voltage, and blocking by foreign
object, shadow, etc. will cause the current to decrease. In addition, when the battery
voltage is high, it will enter a floating charge state, at which point the charge current
will also become smaller and smaller.
Q3:
Why won't my load light up?
A3:
The causes that the load is not turned on may include, the load operating mode
is not set correctly. For example, the light control is set up but the load is not turned
on during the day. In this case, battery is low, resulting in the controller to cut off the
load, or the load is not properly connected, disconnected, burned out or the like.
Q4:
What if I don’t need to use electricity for an appropriately long period of time?
A4:
If the daily power generation of the PV panels is less than the amount of
electricity used by the load, it will result in a situation where the generation does not
cover the consumption. In this case, it is recommended to increase the number of
PV panels. In addition, you can increase the battery capacity, as well as reduce the
wattage of the load or working hours to balance the whole system.
Q5:
Why does a fully charged battery run out of power after a short use?
A5:
The battery is close to the end of life. You can do a simple test. For example,
after discharge, charge the battery by PV panel or mains. The voltage will rise very
soon. Then, stop charging and turn on the load. The voltage drops very soon. This
indicates that the battery performance has degraded. You should replace a battery.
