Automatic 5-45W Solar Controller
The Battery Tender Solar Charger has the following special features:
PN: 021-1162
Battery Tender Solar Controller allows you to convert an existing solar panel into a solar charger using Battery Tender patented Super Smart Charging Algorithm. Usable input range between 5-45 Watts.
Sparkproof: The battery charger DC output leads, either ring terminals or alligator clips must be connected to a battery before an output voltage is developed by the battery charger.
Short circuit protection: The battery charger can sustain a short circuit connection directly across its DC output terminals indefinitely without any risk of either electric shock or excessive heat.
Reverse polarity protection: The battery charger is protected internally against any damage due to the DC output leads being connected to the opposite polarity battery post. No damage will result to either the battery or the battery charger.
Time required to charge a battery: The Battery Tender Solar Charger charges at up to 3.0 Amps Therefore, a fully discharged 15 Amp-Hour battery will take approximately 5 hours, to recharge to 80% capacity with a Battery Tender Solar connected to a 45 watt panel. Some large automotive or marine, deep cycle type batteries may take several days to fully recharge.
Working with a dead battery or a battery with a very low voltage: If you try to charge a dead battery having a voltage below 3 Volts, the battery tender charger will not start to charge because an internal safety circuit prevents the battery chargers from generating any DC output voltage.
