BlueSolar MPPT Charge Controller - 100V - 15AMP Features: Ultra-fast Maximum Power Point Tracking (MPPT): Especially in case of a clouded sky, where light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. Load output: Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof. Some loads (especially inverters) can best be connected directly to the battery, with the inverter remote control connected to the load output. A special interface cable may be needed, please see the manual. Battery Life: intelligent battery management. When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually cycle between a 'partially charged' state and the 'end of discharge' state. This mode of operation (no regular full recharge) can destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e., disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards, the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week. Programmable battery charge algorithm: See the software section on our website for details. Day/night timing and light dimming option: See the software section on our website for details. Programming, real-time data, and history display options: - Color Control GX or other GX devices: see the Venus documents on our website. - A smartphone or other Bluetooth-enabled device: VE.Direct Bluetooth Smart dongle needed.
