Charging procedure<br />
The <strong>de</strong>vice has electronic polarity reversal protection, return<br />
current protection and solar short circuit protection. The<br />
charge current is only enabled if the the battery is correctly<br />
connected and sufficient sunlight power is available (see<br />
"charge diagram").<br />
Main charging phase<br />
Charging with the maximum available solar charging current<br />
until the final charging voltage is reached.<br />
Post-charging phase<br />
The post-charging phase is controlled <strong>de</strong>pending on the discharge<br />
<strong>de</strong>pth.<br />
Trickle charge phase<br />
The charge voltage is set to 13,7 V. The charge current is<br />
reduced to the level that is nee<strong>de</strong>d for the battery to compensate<br />
for self-discharging. The consumers continue to be<br />
supplied. If the consumed current exceeds the available solar<br />
charging current, the charge can no longer be maintained.<br />
If the battery voltage drops below 12.5 V the <strong>de</strong>vice automatically<br />
switches to the main charging phase (if enough solar<br />
charging current is available).<br />
Gassing control<br />
The charging end voltage is modified <strong>de</strong>pending on the discharge<br />
<strong>de</strong>pth. If a battery is operated for a long time without<br />
any gas <strong>de</strong>velopment, there is a risk of damaging acid stratification<br />
building up. This acid stratification can be remedied<br />
by means of limited, controlled gassing. This function is<br />
carried out by the gassing control. If the battery charge is<br />
low and the "gassing active" voltage has been un<strong>de</strong>rshot, the<br />
gassing control disables the overcharging protection until the<br />
so-called gassing end voltage has been reached. The gassing<br />
controller also increases the charge voltage in the event of<br />
strong cyclization, which makes better use of the battery capacity.<br />
This control is also temperature-<strong>de</strong>pen<strong>de</strong>nt, and also<br />
suitable for gel batteries.<br />
Parallel operation<br />
If consumer current is removed during battery charging, it is<br />
taken from the available solar charge current. If the consumed<br />
current exceeds the available solar charging current, the<br />
<strong>de</strong>vice cannot charge the battery. The <strong>de</strong>vice automatically<br />
starts charging when enough solar charge current is available<br />
again.<br />
