SPB-LS/BT is a charge regulator for PV off-grid lighting systems with remote control that uses a wireless standard Bluetooth radio interface.
Thanks to its IP66 metal box, SPB-LS/BT is indicated for outdoor applications.
It is used in PV lighting systems with charge regulator and batteries on the top; the remote control makes easier the knowing of the system working status without having to climb the pole.
SPB-LS/BT has got a very efficient charge circuit with maximum power point tracker (MPPT) algorithm of PV module. SPB-LS/BT can charge 12V or 24V systems with sealed or flooded lead acid batteries and the charge voltage is compensated in temperature.
SPB-LS/BT automatically manages the LED lamp connected to its output; at sunset it turns on the lamp for a predetermined number of hours (timer setting). To protect the battery from deep discharge SPB-LS/BT switches off the lamp if the battery voltage drops below low battery threshold voltage.
From the bottom of the pole, the Bluetooth radio interface of SPB-LS/BT allows:
1) to change internal setting (timer and low battery threshold voltage settings);
2) to know the system status, i.e.: PV module current, voltage, power, battery current, load current, and so on;
3) to download the historical data. SPB-LS/BT stores every 20 minutes its operation data in a memory (data logger function) and the operator can analyze these data by representing them on charts. The internal data logger can store up to 10 years.
