1.5.4. Equalization See section 3.9 1.6 Internal temperature sensor Compensates absorption and float charge voltages for temperature (range 6°C to 40°C) 1.7 Optional external voltage and temperature sensor (range -20°C to 50°C) The Smart Battery Sense is a wireless battery voltage-and-temperature sensor for Victron MPPT Solar Chargers.
2. IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS - This manual contains important instructions that shall be followed during installation and maintenance. Danger of explosion from sparking Danger of electric shock ● It is advised to read this manual carefully before the product is installed and put into use.
3. Installation WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY CIRCUIT CAUTION: FOR PROPER TEMPERATURE COMPENSATION THE AMBIENT CONDITION FOR CHARGER AND BATTERY MUST BE WITHIN 5°C. 3.1. General ● Mount vertically on a non-flammable substrate, with the power terminals facing downwards.

● The controller will operate only if the PV voltage exceeds battery voltage (Vbat). ● PV voltage must exceed Vbat + 5V for the controller to start. Thereafter minimum PV voltage is Vbat + 1V. ● Maximum open circuit PV voltage: 75V respectively 100V For example: 12V battery and mono- or polycristalline panels connected to a 75V controller ●...

Some loads with high inrush current can best be connected directly to the battery. If equipped with a remote on-off input, these loads can be controlled by connecting the load output of the controller to this remote on-off input. A special interface cable may be needed.

3.8 Battery charging information The charge controller starts a new charge cycle every morning, when the sun starts shining. Lead-acid batteries: default method to determine length and end of absorption The charging algorithm behavior of MPPTs differs from AC connected battery chargers. Please read this section of the manual carefully to understand MPPT behavior, and always follow the recommendations of your battery manufacturer.

2. Restarting the charge process The charging algorithm will reset if charging has stopped for an hour. This may occur when the PV voltage drops below the battery voltage due to bad weather, shade or similar. 3. Battery being charged or discharged before solar charging begins The automatic absorption time is based on the start-up battery voltage (see table).
4. Troubleshooting Problem Possible cause Solution Charger does Reversed PV connection Connect PV correctly not function No fuse inserted Insert 20A fuse Blown fuse Reversed battery Connect battery correctly Replace fuse connection A bad battery connection Check battery connection Use cables with larger cross Cable losses too high section Large ambient temperature...
