Victron BlueSolar 15A MPPT Charge Controller (12/24V)
Victron's 15A BlueSolar MPPT charge controller is designed to maximise power output from small solar systems up to 400W (200W at 12V). The MPPT calculations and functionality of the BlueSolar 75/15 and 100/15 are significantly faster, producing up to 10% more than other MPPT controllers in changing weather conditions, such as a clouded sky. The two versions differ by the maximum input voltage from the solar panels; either 75V or 100V.
In addition to protecting the batteries from deep-discharge, by disconnecting any attached electrical devices, Victron have also integrated their 'Battery-Life' algorithm. Sometimes, due to heavy use or very poor weather, the solar panels may not provide enough power to fully recharge the batteries within a 24-hour period. In this case, if activated, the BlueSolar 75/15 and 100/15 will use stored information to slightly increase the battery disconnect voltage. This will continue until the batteries have reached 100% state of charge again. Thereafter, the battery disconnect voltage will be cycled so that a full recharge of the batteries is achieved about once a week.
Since many solar systems are outdoors, Victron have fully encapsulated the BlueSolar 75/15 and 100/15 electronics. This means that the charge controller is IP65 rated, so it can be used outside without any other protection from the weather.
