The power unit is therefore capable of charging the batteries, performing the charging cycle chosen
by the user, depending on the source available.
In the particular case of the solar panel,
no further devices are needed
between the solar
panel and the power supply unit because, as mentioned, the charge adjustment functions are already
carried out by the power supply unit itself.
The power supply unit supports panels also up to 300W, unlike the previous version that was
indicated for 120W.
Case 1 : Assembly of a single Panel
Make sure the panel is fitted with a non-return diode and if not, install one
.
If a single panel is fitted, it should be connected as shown in Figure 4:
In the figure below the panel is understood to be fitted with non-return diode

It should be noted that along the cable of the positive terminal,
near the power supply unit,
a fuse
of adequate amperage is fitted.
How should the fuse cut-off power be chosen?
Clearly, the fuse should be chosen in accordance with the normal operating current and the diameter
of the cable connections used.
Example:
For a generic 100 W panel the maximum current (Short Circuit Current) indicated by the
manufacturer can be approximately:
Short Circuit Current = 7 A
