FAQ
Q:
Why won't my solar panel display charging when connected?
A:
Check whether the connection of solar panels is correct, whether there is reverse
connection, whether the voltage of solar panels is higher than that of batteries,
and whether solar panels are blocked that causes voltage drop. Under normal
circumstances, 12V batteries should use solar panels with rated voltage of 18V.
Q:
Why is my charging current very low?
A:
The higher the power of solar panels, the stronger the sun, and the larger the
charging current. Conversely, incorrect voltage, shadow occlusion will cause the
current to decrease. In addition, when the battery voltage is high, it will enter
the floating charging status, and the charging current will become smaller and
smaller.
Q:
Why my load does not work?
A:
The reasons that cause the load not to work may include incorrect setting of the
load working mode, such as setting light control but asking why the load does
not work during the day, insufficient battery power leading to the controller cut
off the load, or the load is not well connected, disconnected, burn-out of the
load, etc.
Q:
What if I don't have enough time to use electricity?
A:
If the power generated by the solar panels is less than the daily power
consumption of the loads, it will cause the situation that income is not enough.
It is suggested to add solar panels to cope with extreme rainy weather.
In addition, it can increase the capacity of batteries, reduce the wattage of loads
or work time to balance the whole system.
Q:
Why does a full battery run out of power after a short use?
A:
Batteries are close to scrap and it can be tested simply. For example, after dis-
charging, the battery is charged with solar panels or power supply, the voltage
will rise quickly, then the battery will be disconnected, and then the battery will
drop quickly with load, which indicates that the performance of the battery has
declined. In that case, new batteries should be replaced.
