Multi battery chemical available
Multi battery chemical available
Commonly encountered lead acid battery chemicals include AGM, GEL, Traction. The voltage
required for a proper charging of different battery varies. SP offer premium charging for above
commonly encountered battery categories, of which you can set through the LCD and control
button.
2.3.5 Comprehensive Protection
The equipment is being protected against many failures through hardware and software making it
robust and reliable.
PV array reverse polarity protection
PV array reverse polarity protection
When PV reverse polarity is detected, SP will shut down, send out alarm and will resume output
upon corrected the connection.
PV over voltage protection
PV over voltage protection
When SP charger PV voltage is too high, is beyond the scope can be operating voltage, the charger will shut down
output, and by sound and light alarm prompt, to ensure that the charger will not damage.
When the PV voltage exceeds SP charger allows the highest PV open circuit
voltage range, beyond specification use may cause damage, if the customer use
undeserved cause damage, do not provide warranty service.

Battery over temperature protection
Battery over temperature protection
During charging, The SP in the process of charging battery temperature real time acquisition, when the
battery temperature is too high, it will reduce the charging current and shutdown, and fault warning , in
order to prevent thermal runaway of battery.
